Signs Your Roof Needs Attention
A roof rarely fails all at once. These are the warning signs worth having inspected, whether the answer turns out to be a repair or a replacement.
Missing, cracked or curling shingles
Damaged shingles let water reach the layers underneath, and wind can take more with them.
Leaks and water stains
Brown stains on a ceiling or wall, or a damp attic, mean water is getting in somewhere above.
Granules in your gutters
Shingle granules washing into the gutters is a sign the surface of the shingles is wearing.
Damage after a storm
After hail or high wind, have the roof checked even if nothing leaks yet. Some damage is not visible from the ground.

Should I repair or replace my roof?
It depends on how much of the roof is affected. A leak from one spot or a few damaged shingles on an otherwise sound roof can often be repaired. Widespread damage, repeated leaks or shingles that are failing across the roof usually point to replacement. We inspect the roof and tell you which makes sense. Learn more about roof repair and roof replacement.
Which shingles does Casey Exteriors install?
We install CertainTeed Landmark and Landmark PRO shingles and Owens Corning TruDefinition Duration shingles. See CertainTeed Landmark shingles and Owens Corning Duration shingles.
What should I do if my roof is leaking right now?
Call us at (314) 892-5900. Stay off the roof, move belongings out of the way of the leak, and take photos of the damage and any water stains inside. We will tell you what we can do and how soon. If you plan to file an insurance claim, contact your insurer as well.
Do you work with insurance companies on storm damage?
Yes. Casey Exteriors repairs storm damage that goes through homeowners insurance, and we can support your claim with an inspection, photos and an estimate. Your insurance company decides what is covered, and claim rules and deadlines vary by carrier and policy, so check your policy and file promptly. More on storm damage and insurance claims.
Do your shingles come with a warranty?
Yes. CertainTeed Landmark shingles carry a lifetime limited transferable warranty, and Owens Corning Duration shingles carry a limited lifetime warranty. Both warranties have conditions, limits and component requirements, so ask us for the actual warranty documents for the shingle you choose. Ask us about Casey Exteriors’ own workmanship warranty as well.
How long does a roof replacement take?
It depends on the size and design of the roof and on the weather. We give you an expected schedule with your estimate.
