1. Curling, Cracking, or Clawing Shingles
One of the easiest ways to spot trouble is to look at the shape of your asphalt shingles. They are designed to lie flat, creating a seamless waterproof barrier. When you see shingles with edges turning upward (curling) or the middle popping up (clawing), it’s a sign of trouble. You might also notice random cracks spreading across them. This usually happens because of advanced age and years of heat exposure, which causes the asphalt to shrink and deform the shingle. Cracks are often the result of wind damage or simple weathering. In either case, the shingle can no longer shed water properly, creating an entry point for moisture. While you can replace a few damaged shingles, widespread curling or cracking means the entire roofing system has reached the end of its life and a full replacement is needed to restore its protective barrier.
