Shingle Roof Guides

A complete shingle scope should address tear-off or repair limits, decking, underlayment, starter edges, valleys, flashing, ventilation, ridge details, disposal, and cleanup.

Ventilation works with insulation and air sealing to manage attic heat and moisture. Intake, exhaust, roof design, and existing conditions must be evaluated together.

A focused shingle repair needs flexible surrounding material, sound decking and underlayment, and a clean tie-in. Widespread brittleness or repeated leaks can point toward replacement.

Shingle wear should be judged across the roof field. Curling, exposed mat, concentrated granule loss, lifted tabs, cracked sealant, and repeated repairs can indicate different stages of aging.
