Collins Roofing & Maintenance has been installing asphalt shingle roofs across Collins for 20 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.
The difference between a 15-year roof and a 30-year roof isn't the shingle — it's the installation. Proper nail placement in the manufacturer's nailing zone, correct overlap between courses, ice-and-water shield at all vulnerable areas, and flashing that's sealed at every transition. Collins Roofing & Maintenance follows the exact specs that keep the manufacturer warranty valid.
Our Shingle Roofing Process
Free Roof Estimate
Our estimator examines your current roofline, checks the condition of the underlayment and flashing, and presents shingle options with honest pricing. GAF, Owens Corning, CertainTeed — you pick.
Old Roof Removal
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.
Ice Shield & Drip Edge
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.
