Grindstone Roofing & Maintenance has been installing asphalt shingle roofs across Grindstone for 22 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. Grindstone Roofing & Maintenance follows the exact specs that keep the manufacturer warranty valid.
Our Shingle Roofing Process
Consultation & Inspection
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 Grindstone home.
Tear-Off & Deck Prep
Old roof stripped to bare deck. We inspect the plywood or OSB sheathing for structural integrity, replace any compromised boards, and prep a clean, solid substrate for the new underlayment and shingles.
Ice Shield & Drip Edge
Synthetic underlayment across the full roof deck. Ice-and-water shield in valleys, along eaves, and around chimney flashing, pipe boots, and vent boots. New drip edge installed at every eave and rake. Step flashing and counter-flashing at all wall transitions.
Shingle Installation
Field shingles installed with proper exposure and overlap. Nailed per manufacturer specs — 4 nails standard, 6 in high-wind zones. Starter strips at the eave prevent wind uplift. Ridge cap shingles finish every peak with integrated ridge vent for ventilation.
