Don’t wait to fix your leaking roof! Leaks should be repaired immediately to prevent or minimize damage to your roof, structure, and the contents inside and ultimately save you money. One tiny roof leak left unattended is enough to breach the waterproof seal on your home and leave it wide open to water damage. Once moisture gets inside, mildew, rot and mold weaken the structure of your home. Fixing roof problems is not something that can wait until later. Often proper roof repair can add months or years to the life of your roof. The experts at Grennan Construction can help extend the life of your roofing system by locating and repairing even the most difficult leaks.
