The warning signs that you may need to be in the market for a new roof can be hard to spot if you don’t know what you’re looking for. Often, you will have to either get on your roof or climb a ladder to assess your roof’s condition correctly. Ultimately, what you are looking for degradation and damage to the shingles. You don’t want to let your roof deteriorate to the point of leaks since this will mean much more than a roof replacement and will probably require the replacement of beams or joists.
What to look for
To spot a roof in need of replacement, you’ll want to look for the following signs:
- General deterioration of shingles
This can include such things are bald spots on the shingles where granules are missing, curled shingle edges or shingle tabs that are cupped, or cracked shingles. Discolouration can also start to occur at this stage, which can be visible to the naked eye without getting up on a ladder. The shingle will generally begin to look ‘rough’ and pale, with a nubbly texture.
- Your roof is around 20 years old
Many new types of shingles can be rated to last as long as 50 years, but homes built over 20 years ago won’t usually have this kind of shingle. If your roof has been on for around or over twenty years, it may be time to consider replacement. Another good way to tell if your roof is reaching the end of its life is if your neighbors are having theirs done. Homes built around the same time and Roofing in Toronto subdivisions will usually have their roofs fail on a similar timeline.
- You see dark streaks
Airborne algae can lead to dark streaks on the roof. This is not something that will necessarily harm the shingles, but it is a sign they are aging. You can remove these streaks yourself by using a 50/50 blend of water and bleach sprayed onto your roof with a low volume garden hose. Be sure to protect surrounding landscaping if you do this from bleach runoff.
- Moss has set up home
Moss will begin to grow on roofs in cool, wet climates that lack sunlight. While it is aesthetically displeasing, moss growth can be more than a cosmetic issue. Moss holds lots of moisture and can damage your shingles by freezing in winter and damaging the granules. To remove it safely, you may need to hire a professional roofer.
- You see sunlight in your attic
When you can see light in your attic, you have a serious problem on your hands. If light can get into your attic, it means that moisture and the cold also can. This will mean water damage and rot and can quickly cause issues for other areas of your home and your electrical systems.
