Rose Roofing | Roofing Services in Gorham, ME 04038

In our area, roof deck rot is most often caused by trapped moisture from ice dams, damaged flashing, or undetected leaks in valleys. We start by locating and repairing the source of the water intrusion. Then, we remove and replace any rotted plywood or sheathing to restore structural integrity before installing new underlayment and shingles. Proper attic ventilation is also key to preventing future issues.

Roof valleys handle a tremendous amount of water runoff, especially during Maine's heavy rains and snowmelts. Over time, the valley metal or flashing can corrode, or the surrounding shingles can degrade. Our approach is to carefully remove the old material, inspect the underlying deck, and install a new, watertight valley system—often using corrosion-resistant metals—sealed and integrated perfectly with new shingles.

A professional inspection by someone familiar with Gorham's weather patterns can spot early warning signs—like minor leaks, compromised flashing, or poor ventilation—that often lead to deck rot or valley failures. We catch these issues early, saving you from costly structural repairs. Think of it as routine maintenance for your home's first line of defense against the elements.
