Asphalt shingles remain the most popular residential roofing material in PA for good reason. Architectural shingles — also called dimensional or laminated shingles — provide a thicker, textured profile that mimics wood shake or slate. Glenshaw Roofing & Maintenance installs asphalt shingle roofing throughout Glenshaw, from three-tab to premium designer shingles.
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. Glenshaw 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.
Strip & Inspect
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.
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.
Nailing & Overlap
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.
