Cadogan Roofing & Maintenance has been installing asphalt shingle roofs across Cadogan 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.
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. Cadogan Roofing & Maintenance follows the exact specs that keep the manufacturer warranty valid.
Our Shingle Roofing Process
Consultation & Inspection
Free on-site inspection. We measure, assess your roof deck condition, and walk you through architectural vs. three-tab shingles with realistic pricing. No pressure, just facts.
Old Roof Removal
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
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.
Nailing & Overlap
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.
