Roof Replacement in Decatur — Replacement here begins with a number that has nothing to do with your roof's age. How many coverings are already up there decides whether you have a choice at all, and most people who call us have never once been told theirs.
Roof Leak Repair in Decatur — A leak on a doubled-up roof does not behave like a leak on a single one. Water that gets past the top course travels sideways in the space between the two, sometimes for several feet, before it finds a way down through the deck.

Hail Damage Roofing in Decatur — Reading hail on a Decatur roof means reading it through whatever is underneath. A bruise is a fracture in the shingle mat, and the mat behaves differently depending on what is supporting it at the moment the stone lands.
Wind Damage Roofing in Decatur — The most common wind failure we take off Decatur houses is not a bad shingle or a bad storm. It is a nail that never reached wood, on a roof somebody laid over an existing one without changing the fastener.
