Pharr Roofing & Maintenance has been installing asphalt shingle roofs across Pharr for 12 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.
Strip & Inspect
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.
Waterproofing Layer
The waterproofing layer is what protects your home if a shingle ever fails. We install ice-and-water shield at every vulnerable point — valleys, eaves, penetrations — then roll synthetic underlayment over the entire deck. Drip edge directs water into gutters, not behind fascia boards.
Nailing & Overlap
Starter strips along the eave, then field courses of architectural shingles with manufacturer-specified offset and overlap. Each shingle nailed in the designated zone with 4-6 fasteners. Ridge cap shingles hand-nailed at every hip and ridge for a finished, watertight top.
