Roundup Roofing & Maintenance has been installing asphalt shingle roofs across Roundup for 15 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. Roundup 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 Roundup home.
Tear-Off & Deck Prep
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.
Waterproofing Layer
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
Asphalt shingles laid from eave to ridge with precise offset between courses. Every shingle fastened in the manufacturer's nailing zone — too high or too low voids the warranty. Ridge cap and hip shingles complete the system with ridge vents for balanced attic ventilation.
