What affects the price
Roofing repairs vary depending on the extent of the damage and the materials involved. If your leak is isolated to a few shingles, the fix is usually straightforward. However, if the underlying decking is rotted or the flashing around your chimney is compromised, the labor and material needs increase. Steep roof pitches can also add to the cost due to safety requirements. We assess your unique situation to give you a clear picture of what is needed. Exact pricing confirmed free on the call.
About this service
Waterproof sealant is a protective coating applied to roofing materials to stop moisture from seeping into the structure.

Applying a sealant can extend the life of your current roof, though the final cost usually varies based on the product quality and the amount of surface area involved. Exact pricing confirmed free on the call.
The summer heat is perfect for roof work because materials are flexible and sealants set properly.
