Frequently Asked Questions

What are the first signs of roof damage before a leak starts?

The earliest signs of roof damage are curling or lifting shingles, cracked shingles, and granule buildup in your gutters. Inside, water stains on ceilings and a mold or mildew smell in the attic indicate moisture is already getting through. Catching these signs early typically costs far less to repair than waiting until an active leak develops.

How do I check my attic for roof damage?

Go into your attic on a sunny day and look for any daylight visible through the roof boards. Spots of light mean gaps large enough to let in water, insects, and cold air. Also check insulation by feel — wet or compressed insulation is a direct sign of water intrusion from the roof above.

What does granule loss on shingles mean?

Granule loss means the protective surface layer of your asphalt shingles is wearing away. You'll notice it as excessive gritty granules collecting in your gutters. Once granules are gone, the shingle underneath is exposed to UV damage and breaks down faster, shortening the roof's remaining lifespan.

When should I call a roofing contractor instead of handling it myself?

Call a contractor immediately if you see any water intrusion inside the home, sagging sections on the roof deck, or damage that covers 25% or more of the total roof area. Any of these conditions signal structural or widespread problems that go beyond a simple patch repair.

Are cracked shingles a serious problem?

Cracked shingles are a serious concern because visible splits and breaks allow water to seep under the shingle and into the underlayment or deck below. A few isolated cracks can be patched, but widespread cracking across the roof surface usually indicates the shingles are at the end of their useful life.
