Caledon home maintenance: Is it time to repair or replace your old roof? Before you call a roofer, look for these red flags!
1. Age Hold old is your existing roof? Many experts will agree that the typical lifespan of an asphalt shingle roof is between 20-25 years. This also depends on whether or not the old roof was removed, or if you only have one layer of shingles. Another factor is if it has been properly ventilated. If it was installed over another layer or is older than 20 years, you should call an expert.
2. Curling and Buckling If your shingles are curling or buckling, it is a sure sign that you need a new roof. Look at the slopes of your roof that get direct sunlight. If you notice that shingles are curling or losing material it could mean that your shingles are past due and need to be redone.
3. Valleys If you are missing shingles or they are falling apart in these areas, you definitely need a new roof. The valleys of the roof are the most important part. Snow and rain flow through the valleys and into the gutters. Having compromised valleys leaves you more susceptible to leakage.
4.Check Your Gutter For Shingle Granules Look and see whether your gutters are loaded up with shingle granules. Roofs will lose more toward the end of their life expectancy. Inconsistent or darker colours on some parts of the roof is another sign that the shingles have worn away.
5. Missing Shingles This is another sign that your roof could be failing. Check and make sure that your shingle tabs are intact.
6. Always Start Inside If you think you may need a new roof, the first place to check is the attic. So grab a flashlight and climb up under the eaves. You are looking for beams of light coming through the tops of the house, stains or streaks. These are the signs of a leaky roof. After reading this, if 1 or all apply, call a roofer – it’s time to get a new roof! This has been home maintenance 101.
