Coronado Roofing & Maintenance has been installing asphalt shingle roofs across Coronado for 18 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.
Every shingle roof starts with the layers beneath the shingles. Synthetic underlayment rolls across the entire roof deck as the primary waterproof barrier. Ice-and-water shield goes down in the valleys, along the eaves, and around every penetration — chimney flashing, pipe boots, vent boots. Drip edge along every eave and rake directs water into the gutters instead of behind the fascia.
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 Courses
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.
