Obviously, you’ll need to replace your roofing if it has been severely damaged in a storm and was torn off your house. But what if it’s more or less intact? How do you know that it’s time to call your roofing contractor? There are actually several ways to determine when it’s time to replace the shingles, and one of these is to watch out for the following signs:
The roof line isn’t straight
Ideally, your roof should be bone-straight from one end to another. If you see curved or dipped sections, or if the entire roofline is sagging, it most likely indicates a structural issue like improperly installed framing and rotten, waterlogged sheathing. The worst-case scenario is that your house has a problem with its foundation, which would require extensive repairs. Your contractor will help you pinpoint the exact cause of the sagging and suggest the appropriate solution for it.
The shingles are distorted
Exposure to extreme and fluctuating temperatures can cause shingles to develop a cupping, curling, or clawing pattern. This can be an indication of several possible problems: your attic might have poor ventilation, the shingles might have been poorly installed, or they might be nearing the end of their lifespan. No matter what the problem is, though, you’ll want to hire a roofing contractor ASAP since distorted shingles can lead to leaks and eventually water damage.
You see plenty of dark granules in the gutters
Manufacturers cover shingles with granules, which act as a shield against UV damage. Without these granules, the shingles will easily bake under the sun and ultimately deteriorate, which means they won’t protect your house as well as they should. If your gutters are littered with granules, it means the shingles are no longer in good shape and should be replaced.
You replace missing shingles every now and then
This won’t cause any functional problem, but it would make your roofing look like a big chessboard especially if the color of the new shingles don’t match the color of the original shingles. If you’re planning to sell your home in the future, you’ll want to do a full roofing replacement so you can increase your property’s curb appeal.
