Shingle roofing is a layered assembly: asphalt shingle on top, synthetic underlayment beneath, ice-and-water shield along the eave and valley, and metal drip edge at the rake. We fasten each course with ring-shank nails at the manufacturer's spacing.
Architectural shingle outsells three-tab shingle here because the heavier, laminated mat resists granule loss and hail bruising. Dimensional profiles such as GAF Timberline HDZ, Owens Corning Duration, and CertainTeed Landmark Pro add algae-resistant granulated surfaces and stronger wind ratings than builder-grade fiberglass shingle.
As a licensed and insured roofing contractor, we set step flashing and counterflashing to the local building code. We caulk the pipe boot, secure a ridge cap along every hip, and check attic ventilation before we close the roof.
