You know that there’s something a bit wrong with your roof, mostly because you have to put a bowl under that spot in your ceiling that leaks when it rains. But when you go outside you don’t see anything wrong. The shingles look fine to you, and they’re all there. So why is the roof leaking? You figure you could find out if you go up on the roof and take a good look, but there’s no way you’re going up there. How can you tell just where the roof damage is? (Remember you can always call a local roofer to help you out with figuring this all out!)
Look in Your Gutters
If you have a sturdy ladder, climb it and take a look at your gutters and downspouts. If there are dark granules in the gutters, that means that your asphalt shingles are starting to degrade. You can’t tell by looking at a distance, but this is a telltale sign. If you don’t have gutters, see if there are granules around your foundation plantings. Even if the shingles look healthy, the fact that they’re shedding granules means that their watertightness has been compromised.
After a while, so many granules will have fallen off the shingles that you will be able to see bald spots even from the ground. After that, you’ll see the edges of the shingles curl and dry up.
