Decking
The wood surface beneath the roof covering. Ask how damaged sections are documented and priced after tear-off.
HOMEOWNER GUIDE / SHINGLE ROOFING
Understand shingle roofing.
What the parts do, what the terms mean and what to ask before work begins.
Underlayment
A layer between the deck and shingles. Ask which product is specified and where additional water protection is needed.
Starter shingles
The starter course at roof edges, separate from the visible field shingles. Confirm the accessories specified for the chosen system.
Drip edge
Metal at the roof perimeter that helps direct water away from exposed edges. Discuss its relationship to the gutters.
Flashing & pipe boots
Details that manage water where the roof meets walls, pipes and other interruptions. Ask which pieces will be replaced.
Ridge cap & ventilation
Ridge cap covers the roof peak. A ridge vent, where suitable, provides exhaust and needs a coordinated intake path.
