Allentown Roofing & Maintenance has been installing asphalt shingle roofs across Allentown for 16 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.
We install every shingle roof to manufacturer specifications. That means 4-6 nails per shingle in the designated nailing zone, proper offset between courses, starter strips along the eave, and ridge cap shingles at every hip and ridge. When the manufacturer inspector shows up, your roof passes.
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 Allentown home.
Tear-Off & Deck Prep
Full tear-off to the deck. Old shingles, deteriorated felt, and corroded flashing removed and hauled to the dumpster. Deck inspection catches hidden damage — rotted sheathing, water-stained OSB, nail pops — before it's buried under new shingles.
Underlayment & Flashing
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.
Shingle Installation
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.
