Canada’s climate can often be harsh and unpredictable. When it comes to your home, it is important to make sure that you have the right protection for your most important asset – your roof. The following are some warning signs that may help you identify potential roof failure.
Can a roof be replaced in one day?
On average, roofs usually take 2-3 days to replace depending on the size of the roof. Certain roofs can be replaced in one day if it’s a smaller job.
Is roof flashing necessary?
Flashing is completely necessary because it stops water from entering through any joints. Flashing ensures that your home is completely protected and the roof is watertight, not allowing any water in through the joints between the roof and chimney and also the higher roof tiles.
Can a roof collapse?
A roof can collapse if there are structural problems from weather damage, excessive weight or water has managed to work its way into the roof. Bends in the roof support and cracks can also cause significant enough damage to a roof and that could run the risk of the roof collapsing.
What are some maintenance tips to prevent shingle damage?
Checking your roof at least once a year for the early signs of wear and tear is the best way to stop serious shingle damage. Getting your roof professionally inspected periodically is a good investment. Making sure that your eavestroughs are kept clean will help too. As will not letting too much ice build-up and cleaning off any moss and treating mould.
How soon can I expect my new shingles to start curling due to natural aging?
How soon your new shingles start to curl depends on how well they have been laid, what materials have been used and if they are good quality or not. Some cheap asphalt shingles will start to curl after about 10 years. While the best ones are not likely to do so for at least 20.
Should I be worried about mold on my roof?
You should be worried about mould on your roof. Usually, it is a sign that moisture is getting into your home. If you have mould on the outside of your roof you will have it inside too. The other problem is that it is unsightly, which can affect the resale value of your property.
Shingle damage can be caused by a variety of factors, most commonly extreme wind conditions, snow and ice build-up, and over-exposure to the sun. Because shingles are not waterproof, broken, torn or missing tabs become entry points for water. Damaged shingles are of even greater concern on lower sloped roofs where water run-off is slower.
Buckling is a visible distortion of waviness in the horizontal lines of the shingles, and usually runs in a straight line up the roof slope. This distortion allows shingle tabs to become exposed to wind, which can result in blow-offs. Buckling is usually a byproduct of a warped roof deck or poor ventilation. The use of thinner-than-recommended plywood and inadequate air intake/exhaust will act as a catalyst.
During the roof’s natural aging process, the bottom edge of the shingle tabs may begin to curl. The resulting bulge is susceptible to substantial damage by wind, hail, snow & ice, and driving rains. This process can be expedited if ventilation is poor.
Many leaks or pooling of water tend to occur at the flashings around vents, soil stacks, chimneys, skylights and vertical wall joints. Consider the following questions when it comes to your roof’s flashings: Is the flashing cracked? Is the caulking around the flashing dried out? Are the shingles that lie over, in or around the flashings in good shape?
