A new roof is much more than a fresh layer of shingles. It is a complete system designed to move water away from your home, resist weather exposure, support the roof covering, and protect the structure underneath.
That system can include shingles or other roofing materials, underlayment, flashing, ventilation, fasteners, ice and water protection, and the roof deck.
The deck is particularly important because it provides the structural surface beneath the visible roof. If plywood has been repeatedly exposed to moisture, it may swell, soften, warp, or develop rot. Installing new roofing materials over severely damaged wood can leave your new roof with an unstable foundation.
During every roof installation Innisfil project, we pay attention to the condition of the roof deck so problems beneath the surface are not overlooked.
