Flat Roof Information

Flat Roof Information.  A flat roof is a kind of shielding for any building. A flat roof is horizontal or close to horizontal in comparison to the more sloped variety of covering. Roofs that are nearly flat are classified as low-pitch roofs (because the angle of slope rises, therefore, the pitch is said to increase): Typically the slope of your roof is properly termed its pitch.

Each location around the globe have their own tradition or preference regarding products used for flat roofs. A few flat roofing product options include felt, asphalt or bitumen. A flat roof might possibly be covered with roofing shingle or possibly converted to a green rooftop. It may be sealed using a cold applied water-resistant coating or it can becovered with a single ply membrane layer on the whole created from a synthetic polymer that’s been intended to resist weathering, chemical oxidation and UV radiation and to preserve its physical attributes over a variety of temperatures.

Each time a leak does start on a flat roof covering then damage mostly goes unnoticed for very long time frames during which water seeps and soaks the decking and any insulation and/or structure under it. The rot which normally develops and if allowed to remain can potentially weaken the roof structure may lead to costly repairs. Although a argued point, additionally there are various sorts of health risks to those people and animals breathing in the mould spores.

Perhaps the biggest issue with flat roof repair is not generally picking out the product for your weatherproof covering, but detecting the reasons why it leaked at the outset. A great many British flat roofs are too flat and they sag in the middle because they have been constructed with weak structural products, so that allows rainwater to pond, which in turn finds its way through any pinprick imperfection. Whenever water does permeate the barrier covering (be it traditional or a modern membrane layer) it may travel a long way before creating recognizable damage or leaking straight into a property where it can be seen. As a result it is tough to determine where its leaking so that you can repair it.

The upkeep of your flat roof is usually proportional to its life-span. ten years can be the average life-cycle, although this is determined by the type of flat roof system set up.

Additional flat surfaces including balconies have got similar problems to flat roofing and tend to be handled in a similar fashion. Anti slip flooring or slip resistant flooring should also be thought about when deciding on a flooring area.

It’s worth getting suggestions from a specialized roofing contractor about flat roofing selections even if you opt to do the job by yourself. Having a flat roof is a good alternative over having peaked roofs.

The Air Barrier and Your Home

The Air Barrier and Your Home by the Orillia Home Inspector

 

In Ontario the air barrier in a home is installed under the authority of the Ontario Building 9.25.4.3. Installation of Vapour Barriers

 

(1) Vapour barriers shall be installed to protect the entire surfaces of thermally insulated wall,

ceiling and floor assemblies.

(2) Vapour barriers shall be installed sufficiently close to the warm side of insulation to prevent

condensation at design conditions.

 

Where a vapour retarder is employed, the opposite wall surface must provide a permeable surface to allow drying to occur. Thus, in hot, humid, cooling climates, where a vapor retarder is employed at the exterior, the interior wall surfaces should be permeable. Novapor retarder paints, kraft-faced insulation, or vinyl wall coverings should be used. Conversely, in northern heating climates, with interior vapour retarders, the exterior wall coverings should be vapour permeable. This simply means that in warmer climates where cooling is the main concern, the vapour barrier would be installed on the outside of the insulation.

 

House wraps are a permeable surface which, while protecting your home from the elements allows moisture to pass. This allows any moisture that is between your vapour barrier and house wrap can escape and evaporate rather than collecting in your wall system. The primary attribute of house wraps is their ability to operate as air infiltration barriers while not forming an impervious vapour barrier. When placed over the exterior surface of the wall sheathing, the material allows moisture vapour to escape from the frame wall cavity while reducing convective air movement in the insulation, thereby helping to maintain the composite R-value of the wall.

 

The Dew Point of your house is the area where warm moist air will convert to moisture. The dewpoint is a measure of atmospheric moisture. It is the temperature at which air must be cooled in order to reach saturation (assuming that air pressure and moisture content are constant). As the surface of the earth cools at night, warm moist air near the ground is chilled and water vapour in the air condenses into droplets on the grass and other objects. Dew is particularly heavy on clear nights, when the earth cools rapidly. When a blanket of cloud insulates the earth, the cooling rate is slower. The greater the difference between the temperature and the dew point, the drier the air

 

When warm moist air infiltrates your vapour barrier, and passes through to your exterior wall, when it meets a cold surface or void, moisture is created as it cooled to its dew point.   This can cause wet insulation, frost on exterior walls and in some cases even mould.

 

Prevention is possible by ensuring all your insulation is covered by a vapour barrier, most codes call for a minimum of 6 mm poly, and all penetrations are overlapped and taped by Tuck tape, the red tape not the silver duct tape of Red Green fame. All electrical boxes,  windows,   switches, and  vent penetrations should be tightly sealed.

 

Basements are more susceptible   to breaks in vapour barriers due to the fact that most services are located there and many installers fail to replace insulation and repair holes in vapour barriers etc. This can be increased if you have laundry facilities located in your basement and an open sump hole which contains water.

 

Humidity is the main factor of the creation of moisture and if you live in a climate where the humidity is less than 35% this would not be an issue for you.   So if you have high humidity using a dehumidifier in your basement can alleviate these moisture problems.

Furnace Maintenance Tips

Furnace Maintenance Tips

Written by Roger Frost, the Barrie Home Inspector

Heating system and maintenance

In general, heating systems are easy to maintain and are usually trouble free. Efficient operation is a function of good regular maintenance. There are several things you can do to keep your heating system in top condition no matter the type of furnace you have. When a heating or cooling system fails, it is typically one of three things creating the issue ( the heat/cold source , the distribution system and/or the thermostat) . If the furnace or A/C doesn’t work , chances are the issue is at the source. The unit may have lost power , fuel may not be reaching the unit or the fuel may not be igniting. If the unit turns on but the cold or warm air isn’t reaching the rooms , the blower or distribution system may be faulty. A faulty thermostat or control , could keep the unit from turning on or cause it to turn on and off repeatedly. Whatever the problem, start with the simplest procedures. In most cases, all it takes is patience and common sense.

Before working on the system , take these preliminary steps:

Make sure the unit is receiving power . Make sure the unit doesn’t have a blown fuse or tripped breaker. Some furnaces have a separate power entrance on a separate panel and some have fuses mounted on or in the unit.
If the unit has a reset button , let the motor cool down and press the button. If it doesn’t work right away , wait a little while and try it again.
Make sure the units power switch is turned on. Remember , the unit may have a separate power switch.
If it is a gas burning unit, make sure the gas is on and the pilot light is lit. If it’s an oil burning unit check and make sure there is an adequate supply of oil.

If working on the system is necessary remember these important safety factors :

Before doing any work on the unit , make sure all power to the unit is turned off. Remember the unit could be on a separate panel. Make sure the breakers are tripped or the fuses are removed for the particular unit. If your not sure which breaker or fuse it is , trip the main breaker or remove the main fuse to shut off the power to the entire house.
If the unit is constantly tripping breakers or blowing fuses then there is an issue with the electrical. If this is the case , call a professional service person.
If your home smells of gas , leave your home immediately, leave the door open and call the gas company to report a leak. Do not turn any lights on or off and do not re-enter your home.

Keep your furnace clean

Dirt is your furnaces greatest enemy. It can waste fuel drastically lowering the units efficiency. Dirt affect three basic components on your furnace ( the filter , the blower and the motor ) so keeping them clean is the most important part of furnace maintenance. A disposable furnace filter should be replaced monthly during periods of continuous use. To check the filter , simply remove it and check to see if it looks clogged. If it looks clogged replace it regardless of how long it has been used. Install the filter with the arrow on the outer edge pointing towards the blower on the inside of the furnace. The filter size should be marked on the outer edges of the filter.

A permanent filter can usually be cleaned with a filter coating chemical which should be available at your local hardware store. Clean this filter according to the manufacturer’s instructions which may be located in the furnace housing.

Cleaning the blower assembly is also important for maintaining your furnace because the openings can often become clogged with dirt. To clean blower, remove panel that covers filter to gain access to blower or panel on front of furnace. This panel may be slip-fit on hooks or held by series of retaining screws. Access to inside of blower is usually gained by sliding out fan unit, which is held on track by screws. With toothbrush, clean each fan blade and spaces between blades. Then, with vacuum cleaner hose, remove all dirt and debris loosened by brushing. Also vacuum belts and pulleys. Wipe motor housing clean to prevent heat build-up in the motor.

Keep your furnace motor lubricated

To keep your furnace motor running cool, make sure it’s clean. Most furnace motors are permanently lubricated and sealed by the manufacturer however some have covered oil ports above the bearings near the motor shaft. If your furnace motor has oil ports , it should be lubricated annually .Apply two or three drops of 10-weight non-detergent motor oil (not all-purpose oil) to each port. Do not over lubricate. If the blower shaft also has oil ports then it should be lubricated as well. If the blower shaft has grease cups instead of oil ports then remove the caps from the grease cups and fill the cups with bearing lubricant which should be available at your local hardware store.

Inspect on your furnace belt

While lubricating your furnace motor, it is a good time to check the belts. If the belts are worn or frayed , replace them with new one’s that are the same type and size. If the belt squeaks while the motor is running , spray it with fan belt dressing which should be available at your local hardware store. These steps should hopefully help keep your furnace healthy and your family warm for years to come.

To keep the unit in good shape , have it professionally serviced annually. The end of the heating season is usually the best time to do this because of off-season discounts and the company won’t likely be as busy. It a good idea to have your air conditioning unit serviced at the same time.

Which Is The Best Way To Eradicate Termites?

Which Is The Best Way To Eradicate Termites?   The question of which is the best termite treatment? is a tricky one to resolve, because the reply relies partly on your point of view on the widespread use of chemicals. The debate on the usage of chemical pesticides has been going on since the Second World War and even before.

In the Forties and Fifties, many countries that had been involved in the fighting had grave bomb and shell damage, so the local governments took advantage of the clean-up to obliterate all the old inner city slums.

As they did so they observed plagues, simply plagues of bed bugs, cockroaches, rats and other pests, so they spread chemical killers such as DDT everywhere in large quantities. A similar process, for different reasons, was carried out in the United States.

This had the desired effect of destroying the pests, but there was already unease, that insects may become immune to these insecticides. The use of DDT was later banned. The qualms of those who worried about insects becoming resistant, were at least partly warranted and so the debate goes on on. In this article, we will look exclusively at: which is the best termite treatment.

There are three basic methods of termite control: fumigation, baiting and soil barriers

Fumigation involves the gassing of termites. A tent is built around the building in question and gas toxic to termites is pumped into your house from top to bottom and between the exterior walls and the tent.

This gas is then forced into every nook and cranny by fans and it is left there for about twenty-four hours. Then the tent is removed and the gas is extracted from the house by the same fans.

The treatment takes three days. You will move out on day one and back in on day three. The gas only kills termites, they say, so all your mice, spiders and cockroaches will be left unscathed. You will get a warranty that the house is free of all termites. However, some people are not enthusiastic about the idea of fumigating.

Baiting involves laying bait stations around the house and monitoring them for termite activity. This can be carried out by yourself or you can have a pest control firm do it for you. Once the wooden bait shows signs of termites, then the bait is poisoned.

The principle is that the poison is taken back to the colony where it is passed on the the others either by bodily contact or feeding. This process takes longer to eradicate a nest than the three days of fumigation.

Creating a soil barrier means exactly that, you poison the soil around and underneath your home, so that as soon as a subterranean species of termite burrows into your garden it is stopped dead. Quite literally and subterranean termites are the worst of the three kinds. However, a lot of people hesitate at the idea of poisoning hundreds of tons of earth just to kill termites.

So, the debate on the matter of: which is the best termite treatment? goes on. A lot of it centres on your gut feelings about chemicals, but at the end of the day, ‘you pays your money and you takes your choice’.

Sleeping Patterns of the Elderly

Sleeping Patterns of the Elderly.  Many elderly people complain about getting less sleep.  We think this is related to getting older. While it’s a common belief that getting older means less sleep and more fatigue, a new study suggests that older adults may actually enjoy better sleep than their younger counterparts.

Researchers conducted phone surveys of more than 150,000 Americans and found that people in their 80s had the fewest complaints about sleep disturbances and daytime fatigue compared to other age groups. The study appears in the March edition of the journal Sleep.

Some sleep specialists think we have got to get away from all these myths about ageing – many people are very content with their sleep.” However, he said that asking people for their subjective opinion about sleep patterns could produce answers that were dependent on their mood at the time. “If you are angry because your boss didn”t give you a pay rise, your perception of sleep quality may be very different from someone who is feeling generally content.

It’s not clear why older people reported fewer sleep disturbances and tiredness, the authors said. It could be that older people have more control over sleep duration while younger people experience more stressors (jobs, kids, socializing) that interfere with sleep. It’s also possible that older people are just more accepting of sleep quality and don’t complain about it as much.

As we age, our bodies secrete less of two important sleep hormones: melatonin and growth hormone. Melatonin is important because changes in the level of this hormone control our sleep cycle. With less melatonin, many older adults feel sleepy in the early evening and wake up in the early morning. They also may have more trouble falling asleep. Growth hormone is what makes children sleep so deeply. As we age, our body secretes less of this hormone and deep sleep becomes more difficult.

Sunlight helps your body to produce melatonin, which regulates your sleep cycle. Try to get at least two hours of exposure to bright light each day. If it is difficult for you to get outside, consider using a full-spectrum light indoors.  Using alcohol, nicotine or caffeine can also affect your sleep patterns.

Regular exercise and healthy eating habits could be all that is required to make your dreams come true for your next evening sleep.  Adopting a more active lifestyle can make the world of difference in most elderly peoples lives.  Always consult with your doctor before starting an exercise program or changing your diet.

Government Trying to Infringe On Our Privacy

Government Trying to Infringe On Our Privacy. A majority of Canadians think that the Conservatives’ proposed online surveillance Bill C-30 is too intrusive and should be defeated,  according to a poll by Angus-Reid. The poll, conducted February 23-24 and surveying 1,011 respondents on the polling firm’s online panel, found 53 per cent of Canadians believe the bill is too intrusive, compared to only 27 per cent who believe the it is necessary to fight online criminal activity.

The Privacy International investigation revealed that surveillance companies commonly promote virtually unlimited monitoring capabilities to governments and police agencies. For example, Italian-based Innova offers “solutions for the interception of any kind of protocols and IP-based communication, such as web browsing, email and web-mails, social networks, peer-to-peer communication, chat and videochat.”

“The government has a voracious appetite for our private information. Now, with electronic records, we do that by linking electronic databases without ever creating the actual, old file. It’s all already there,” said Micheal Vonn, policy director with the B.C. Civil Liberties Association.

Section 33 tells us that, ‘The Minister may designate persons or classes of persons as inspectors for the purposes of the administration and enforcement of this Act.’..Section 34 spells out the sweeping powers of these “inspectors.” And, if they sound Orwellian, welcome to the world of Section 34.

The inspectors may “enter any place owned by, or under the control of, any telecommunications service provider in which the inspector has reasonable grounds to believe there is any document, information, transmission apparatus, telecommunications facility or any other thing to which this Act applies.” And, once he or she is in, anything goes. The inspector, says the bill, may “examine any document, information or thing found in the place and open or cause to be opened any container or other thing.” He or she may also “use, or cause to be used, any computer system in the place to search and examine any information contained in or available to the system.”

There is an inherent lack of transparency in this bill that extends way beyond what the government is telling us,  are you surprised? Included in this bill is the fact that, by default everyone has the right to ask any company that is subject to the law what information they have about him or her, how they’ve used it and to whom they’ve disclosed it. That is, unless that right is overridden by Section 9. Section 23 of C-30 essentially says that any personal information that is handed over without a warrant under the lawful access law has to be treated in the same way under PIPEDA as information disclosed in response to a law enforcement request. Here’s where the gag order kicks in. If the person exercises his lawful right to seek his or her personal information and accounting of its use, the ISP is prohibited from telling him or her unless the police, national security agencies or competition cops give their OK. And they can refuse to give their OK on a number of relatively flexible bases.

Ontario Commercial Building Inspector

The inspection of Commercial Properties is performed by someone who has experience and knowledge to inspect structures such as; residential, mixed-use, factories, storage, office buildings, restaurants or any combinations of these.  This will provide potential buyer with a PCA report that will enable him to make his purchasing decision based on the findings.

As a member of NACBI our inspectors represent the best of the best with experience and professionalism for our respective trades. NACBI members follow the industry nationally accepted guidelines of ASTM International for Property Condition Assessments and Inspection Institute standards of practice for infrared thermal imaging Inspections.

Commercial Buildings usually fall under a separate part of the building code for a reason.  The bigger the building the more complicated the design. Large Buildings is an intensive course dealing with the Occupancy of Buildings; Building Fire Safety; Safety within Floor Areas; Exits; Barrier Free Design; Structural Design; Change of Use and Renovations to name a few.  As you can see from the subject titles all of these aspects of a building are important and can be very expensive to repair or upgrade.

Commercial property’ covers a range of options from office and retail space through to car parks and industrial properties like warehouses and factories. You may be surprised by this, but investing in commercial properties can be quite affordable, sometimes costing less than many residential properties. There is now a defined protocol for due diligence building inspections. For years, there has been a well-defined standard for performing Environmental Site Assessments. This new protocol should eventually make it easier for those involved with commercial real estate transactions, as the report contents and format have been well defined.

The Commercial Building Inspector  www.commercialbuildinginspector.ca also provides Environmental Assessments. A Phase I ESA is an assessment of a property conducted in accordance with the regulations to determine the likelihood that one or more contaminants have affected any land or water on, in or under the property. The Phase I ESA provides preliminary information about environmental conditions on the property; a determination of the need for, and where necessary, a basis for carrying out any Phase II ESA.

The Commercial Building Inspector has inspected Plaza’s, Strip Malls, Office Complex’s, Factories and Industrial Buildings, Churches, Mixed Use Commercial,  residential apartment buildings, Commercial Leases and properties valued up to 30 million dollars.  We use the lastest equipment and all our staff are highly trained in the Ontario Building Code and have many years of practical experience which ensures your investment will be protected.

Search Engine Optimization

Search engine optimization (SEO) is the process of improving the visibility of a website or a web page in search engines via the “natural” or un-paid (“organic” or “algorithmic”) search results. In general, the earlier (or higher ranked on the search results page), and more frequently a site appears in the search results list, the more visitors it will receive from the search engine’s users. SEO may target different kinds of search, including image search, local search, video search, academic search, news search and industry-specific vertical search engines.

The term “search engine friendly” may be used to describe website designs, menus, content management systems, images, videos, shopping carts, and other elements that have been optimized for the purpose of search engine exposure.

Early versions of search algorithms relied on webmaster-provided information such as the keyword meta tag, or index files in engines like ALIWEB. Meta tags provide a guide to each page’s content. Using meta data to index pages was found to be less than reliable, however, because the webmaster’s choice of keywords in the meta tag could potentially be an inaccurate representation of the site’s actual content.

White Hat SEO refers to the “legal” types of optimization that is allowed and even recommended by the different Search Engines. Google has many tips for Webmasters to improve their visibility and page rank position. What is white hat SEO (sometimes called ethical SEO) anyway? It’s not an easy concept to explain, but it’s important to understand what it means if you’re looking to create a stable, uninterrupted online business.

Black Hat SEO black practices will actually provide short-term gains in terms of rankings, but if you are discovered utilizing these spammy techniques on your Web site, you run the risk of being penalized by search engines. Black hat SEO basically is a short-sighted solution to a long-term problem, which is creating a Web site that provides both a great user experience and all that goes with that.

Sandbox and aging delay are similar in meaning and many SEO experts use them interchangeably. Aging delay is more self-explanatory – sites are “delayed” till they come of age. Well, unlike in legislation, with search engines this age is not defined and it differs. There are cases when several sites were launched in the same day, were indexed within a week from each other but the aging delay for each of them expired in different months.

Google constantly re-configures how they rank individual sites.  SEO people call this the “Google Dance” and it does make their work harder.  The last Penquin change to Google’s algorithm has affected many sites which may change for the better or worse in the future.

Inspection of a Gas Furnace

Inspection of a Gas Furnace.  Inspecting your natural gas furnace will detect problems and save you money in the long run.  Typically gas furnaces are divided into two categories, high efficiency models and standard efficiency models.  The up-draft model is the most popular.

Newer furnaces do not require chimneys as the products of combustion are turned into a vapour and vented to the outside through PVC lines.  ABS pipe is no longer permitted to be used for venting and must be up-graded to 636 PVC when changing furnace.

The major energy saving in high efficiency furnaces is by eliminating the heat loss up the chimney, which continues even when furnace is not running.  The combined loss through heat loss and products of combustion is substantial.

AFUE rating of furnace is the estimated energy efficiency rating of the furnace based on one year. The high efficiency furnace will actually produce heat at a cooler temperature than conventional furnace due to the fact that more heat is extracted from combustion which is why the need for a chimney is eliminated.

The components of gas fired furnaces which are typically inspected. Gas fired furnaces are comprised of a cabinet, distribution system, heat exchanger, fan and controls and a thermostat.  Humidifiers, HRV’s and electronic filters are just some of the accessories you may find installed on a furnace.

Inspection areas of Gas Furnace. Four main areas of furnace inspections are;

1.  Take off fan and burner cabinet covers. Always ensure power is off.
2.  Check the heat exchanger, either using light and mirror or combination of tests.
3. Start up the furnace so a visual inspection of flame and exhaust system may be performed.
4.  Inspect ducts and supply air systems through out the house.

Life Expectancy

Most gas furnaces are expected to last from 20 to 25 years.  The heat exchanger is usually guaranteed for 20 years.  Failure of heat exchanger usually means replacement of furnace.

Regular service and maintenance can greatly extend the life of your furnace and some furnaces will last over 35 years.

Your Home Exterior Finish

Your home exterior finish.  A cornice can be any horizontal decorative trim located at the top of any building or architectural element.  The term cornice comes from the Italian cornice, meaning “ledge.”  A cornice usually refers to the horizontal decorative trim at the top of an exterior wall and below the roof edge of a building, but a cornice can be over a door or window. The function of the projecting cornice is to throw rainwater free of a building’s walls.  At a residential home, this function is handled by projecting gable ends, roof eaves and gutters.  The cornice may include decorative trim.  Highly decorative trim is often called an entablature.

Quoins are used as a detail at the corner of two walls. Quoins typically project from the face of the walls on both sides of the corner.  Quoins can function as the cornerstones of brick or stone walls.  Quoins may be structural, or may be simply decorative. The most common form of decorative use for quoins is as an alternating pattern of rectangular blocks that wrap around the wall, mimicking the pattern of stone blocks or bricks as they would wrap around a corner and thus join the two walls.

A double-hung window has two operable sashes that move.  Many older and historical homes have double-hung windows.  This window is a traditional style of window in the U.S.  The window has two parts (sashes) that overlap slightly and slide up and down inside the frame.   Most new double-hung sash windows use spring balances to support the sashes.  Traditionally, counterweights were used. The weights are attached to the sashes using pulleys of either a cord or chain. An awning window is a casement window that is hinged at the top.  The window hangs horizontally by the hinges.  It swings outward like an awning.  It typically opens outward and operates with a crank.
Siding is the exterior wall covering or cladding of a house.  It is the “skin” of a house’s exterior.  Its primary function is to keep out the weather and provide the building’s aesthetic look.  It protects against wind, rain and snow.  It takes a blow from a baseball or the scraping from a tree branch.  Apart from providing the external appearance of the house, the primary function of cladding is to protect the structure from weather, particularly to shed rainwater.  This may be achieved by using one of the following:

porous materials.  Porous materials, such as brick, absorb water during rain and subsequently dry out.  If the wall is thick and the permeability is low, the water will not penetrate during a rainstorm.  A cavity is normally designed in the wall of porous materials to provide a pathway for possible water intrusion; sealed construction.  Impermeable siding materials permit the intrusion of water only at the joints.  Sealing the joints creates an impermeable layer that is continuous; or
a rainscreen.  The purpose of a rainscreen siding material is to protect the wall from direct rain.  The joints may allow some water penetration, but an air gap and water-resistant barrier behind the siding limit the penetration.  An air gap with ventilation is designed into the wall to encourage drying out.

There are many different types of siding.  As an inspector, you may see a wide variety of materials installed on the outside of houses.  Siding may be made of wood, metal, plastic (vinyl), masonry, or composite materials. It may be attached directly to the building’s structure or to an intermediate layer of sheathing.  You may see shingles or shakes, bricks or stone, aluminum or vinyl, or combinations of siding materials on the same home.  You may see siding that is painted or stained, or wood siding on top of brick, or stucco installed on top of steel siding materials.  You may see wood siding installed vertically, horizontally or diagonally.

Vinyl siding has always been designed as an exterior cladding, not a water-resistant barrier.
Vinyl siding is designed to allow the material underneath it to breathe; therefore, it is not a watertight covering. Vinyl siding provides a supplemental rainscreen that enhances the water-resistive barrier system by reducing the amount of water that reaches the underlying water-resistant barrier.

Many siding problems are caused by improperly applied paint.  Paint on siding may blister, peel, crack, fade or chalk.  Some paint problems are caused by interior moisture that passes through the wall and lifts the paint.  Semi-transparent, oil-based stains can be applied to wood siding.  Most beveled wood sidings have one rough-sawn side that absorbs paint and stain well.  Unlike paint, stains do not lift (blister), peel, crack or chalk.  Some woods can be allowed to weather without any stain applied.  Vertical-grain, all-heartwood redwood and cedar are two ideal woods used for exterior siding.

During your home inspection a professional home inspector will carefully inspect the exterior of your home and note any deficiencies.  The Barrie Home Inspector has experience with most types of siding and with over 4,000 inspections performed is a premier home inspector in the Barrie, Alliston and Orillia area.
