If you have an asphalt shingle roof, you can count on around 20 years of durability with proper maintenance. Roofs that persist longer than this begin to have trouble, and will eventually fail when faced with a storm or other stress. To avoid this catastrophic consequence, pay attention to the following signs that you need a new roof.
The most frequently cited reason for the replacement of a roof comes from simple old age. As a roof persists past its general lifespan, it begins to have consistent problems. Small areas of wear accumulate, and the roof weakens in its resistance to high winds and storms. Even a roof that looks perfectly serviceable can exist on the brink of failure. Your best bet is to take preemptive action with the installation of a new roof.
Another sign of impending failure comes from the frequent need for repair. If your roof necessitates repairs more than once a year, you should probably have it replaced. Frequent repair needs can indicate an aged roof, or one that has inherent flaws. Either way, you will save money in the long run with a fresh installation.
A final indicator that you need a new roof appears when you clean your gutters. If you notice an abundance of roofing granules, then your shingles have become vulnerable. Granules exist to protect shingles from impacts and damage from the sun. As shingles age, they will lose granules to the point where they are no longer serviceable.
