Garvin Roofing & Maintenance has been installing asphalt shingle roofs across Garvin for 14 years. GAF Timberline HDZ, Owens Corning Duration, CertainTeed Landmark — we carry the top shingle lines and we're certified by the manufacturers to install them.
We install every shingle roof to manufacturer specifications. That means 4-6 nails per shingle in the designated nailing zone, proper offset between courses, starter strips along the eave, and ridge cap shingles at every hip and ridge. When the manufacturer inspector shows up, your roof passes.
Our Shingle Roofing Process
Free Roof Estimate
We inspect your existing roof deck and sheathing, measure the area, and help you choose between architectural and three-tab asphalt shingles. Color samples brought to your Garvin home.
Strip & Inspect
We strip the old shingles, underlayment, and damaged flashing down to the roof deck. Every square foot of OSB or plywood sheathing inspected for rot, water damage, and soft spots. Compromised decking replaced before new materials go down.
Underlayment & Flashing
Ice-and-water shield bonded at valleys and eave lines. Synthetic underlayment over the full deck. New aluminum drip edge at every eave and rake. All flashing — chimney, pipe, vent, wall — sealed and secured before a single shingle goes down.
Shingle Installation
Starter strips along the eave, then field courses of architectural shingles with manufacturer-specified offset and overlap. Each shingle nailed in the designated zone with 4-6 fasteners. Ridge cap shingles hand-nailed at every hip and ridge for a finished, watertight top.
