Your Roofing System and How It Works
Shingles are only the outer layer. Decking, underlayment, ice-and-water protection, flashing and ventilation all have distinct jobs.
Exterior work gets easier to plan when the homeowner understands what each system does, which warning signs matter and what questions to ask before the estimate.
The roof deck carries the system
Plywood or other roof decking provides the structural surface beneath the roofing layers. Soft or damaged areas need to be addressed before new shingles hide them again.
Water protection is layered
Underlayment and ice-and-water membranes help manage wind-driven rain and ice-dam risk while metal flashings protect intersections, valleys and penetrations.
Ventilation manages heat and moisture
A balanced attic ventilation strategy can reduce moisture accumulation and help the roof assembly perform more consistently through Nova Scotia's seasonal changes.
