When is time to replace your asphalt shingle roof?

Taking care of your building, especially the roof is one of the most critical aspects of any home maintenance. In fact, your roof has a lot of responsibility and its one of the elements of a home, which must be in good conditions at all times. Many homeowners fail to inspect their roofs from time to time, allowing problems like roof leaks to arise. Sometimes, it’s impossible to predict when a roof will begin to leak or fail, but there are many signs that show when to replace an asphalt shingle roof. Some of them are as follows:

1. Curling shingles

Curling is caused when the asphalt in the shingles is drying and shrinking. The situation cannot be reversed and the shingles becomes brittle, hence starting to blow off, especially in high winds. Good Toronto roofing contractors will definitely advice you to consider a replacement of your roof since this is a sign that your roof is getting old.





2. Abundant moss on the shingle roof

Moss growth on your asphalt shingles doesn’t mean that your shingles are worn out or old, especially if it’s just a section of the roof. If this is the case, it can be easily cleaned. However, if the growth of moss is abundant and widespread then it will definitely start to damage the singles of your roof. Mostly, it gets under the shingles and begin lifting them up. If this condition is prevented before worsening, then the damage would not affect the roof. However, if it’s not prevented it will prematurely shorten the life and damage your roof, leading to roof leaks.


3. Missing granules

When the asphalt misses granules is a common sign that you need to replace your asphalt shingle roof. When viewed from the ground, they look like dark patches and if the shingles are black, there are lighter patches on the roof when the granules fall off. In addition, large amounts of granules are collected in the gutters as they fall of the roof and you will notice them when cleaning your gutters. These granules don’t act as waterproof, so if they fall off you wouldn’t get roof leaks, but they protect your asphalt in the single against damage caused by the UV rays directly from the sun. This means that once they are missing, the singles will definitely wear out faster.

4. The age of your shingle roof

Age is also a factor to consider when determining whether your asphalt shingle roof needs a replacement or not. It can be a full roof replacement or just a mere roof repair. Some reputable Toronto roofing companies or contractors can advice when to consider a repair or replacement of your roof based on its age.



5. Buckling
