1. Check the Integrity of your Roofing Boards
One of the first things you should do to check the integrity of your roofing boards, is to take a look it from the attic. While you’re there look for any daylight shining through the roofing boards. Also look for any signs of water stains or other damage.
If everything looks good from the attic, get up there and make sure there’s no bounce or spongy feel.
2. Check the Valleys
The valleys on your roof are some of the most important areas for protecting your home. Water is directed into these valleys as it moves into your gutters. If any of your valleys are cracked or compromised in any way, it won’t be long before leaks start to occur.
3. Take a Look at Your Chimney Flashing
Chimney flashing areas are similar to roof valleys as they also handle the flow of a lot of water. Make sure the flashing is solid and replace any tar or cement flashing with a metal system.
4. Is Your Roof Missing Shingles?
While it may seem obvious, you may not normally notice missing shingles if they are in specific places . It is essential that you check all of your shingles to make sure they are all intact.
5. Do You Have Buckling or Curling Shingles?
If your roof still has all of its shingles, you should check for buckling or curling shingles next. Focus on the parts of your roof that receive direct sunlight. These issues may mean your roof is past its life expectancy, or it could mean that the shingles are simply defective.
6. Are Your Gutters Full of Shingle Granules?
If all your shingles appear to be functioning properly, you should also take a look at your gutters. If they are full of shingle granules, you may need a replacement. Shingles start to lose more granules at the end of their life cycles.
7. How Old is it?
On average, most roofing experts believe that an average roof should last 20 to 25 years. This lifespan can be reduced further if the roof is not properly ventilated or installed over another layer (or multiple layers in some cases) of shingles.
