When it comes to the health of your roof, your shingles are often the biggest indicator. Looking at you shingles can give you a good idea of what is wrong with your roof so that you know when to call in a roofing contractor to take a closer look.
If your shingles are cracking around the edges, this is an indicator that the granules – the sandpapery stuff on top of the shingles, have worn off. This causes the shingles to become brittle, which means that they definitely need to be replaced.
If the edges of your shingles are curling up, or cupping, it could mean one of two things. Shingles start cupping over time as they become worn out. It could also mean that your attic is not properly ventilated. If your attic is too hot, it can actually speed up the aging process of your shingles.
If your shingles are cupping, you should call a roofing contractor to replace the shingles on your roof and check your ventilation to make sure it’s working properly.
If patches of shingles are missing from your roof, it could mean that the sealant attaching the shingles to your roof has degraded. Once this happens, severe winds can easily loosen and pull off your shingles.
Leaving your shingles missing can cause water damage, so it’s important to have them replaced right away.
Black stains on your shingles mean that algae are growing on your shingles. This is mainly an aesthetic problem, which can lessen the curb appeal of your home. Next time you reroof, consider getting algae-resistant shingles to prevent this.
