Grangeville Roofing & Maintenance has been installing asphalt shingle roofs across Grangeville for 17 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.
Architectural shingles are heavier and more wind-resistant than three-tab because of their laminated, multi-layer construction. The fiberglass mat provides the structural base, asphalt makes it waterproof, and the granulated ceramic surface protects against UV radiation and provides fire resistance. We install them over synthetic underlayment with ice-and-water shield at valleys and eaves.
Our Shingle Roofing Process
Shingle Selection
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 Grangeville 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
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 Courses
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.
