Shingles that have curled edges are usually on their way out, and won’t last much longer. When it comes to shingles, your roof’s shingles should lay flat against each other. This keeps water from getting to the surface of your roof, where it shouldn’t be. If you see bent or warped shingles, usually that’s a sign of age, and that they’ve endured a lot of temperature swings and different forms of weather.
Torn, Missing, Or Cracked Shingles
If your shingles show tears, cracks, they’re moved, or they’re completely missing, this is an obvious sign that your roof needs to be replaced. These indications are a bit more serious because if they are left untouched, it can lead to further, more serious damage. Shingles can break, shift, or fly away entirely when your roof faces severe weather, or if your roof was installed poorly to begin with.
Lack Of Granules
Shingles are textured with small granules. These granules are important for shedding water over the surface of shingles, so it doesn’t impact the roof or cause leaks. They also protect your roof from UV rays, and add to the look of your home with their color and texture. A lack of granules is a sign of a need for a roof replacement.
Discoloration On Shingles
Discoloration of your roof’s shingles is a natural part of the wear and tear associated with a roof. However, complete discoloration is a sign that your shingles are outdated and are in need of replacement.
Moss And Algae Growth
Moss and algae are not good signs to see on your roof. Moss and algae hold moisture against the surface of your roof, and can lead to moisture penetrating to the subsurface of your roof. Simply cleaning the moss and algae off of your roof doesn’t guarantee that it won’t come back. If you see green peeking on the edge of your shingles, it’s a good time to think about a new roof.
An Old Roof
How old is your roof? If it’s 20 years or older, most likely, it’ll need to be replaced. Roofs with shingles that are being used beyond their lifetime are at higher risk for failing and causing leaks.
