Asphalt shingles remain the most popular residential roofing material in GA for good reason. Architectural shingles — also called dimensional or laminated shingles — provide a thicker, textured profile that mimics wood shake or slate. Portal Roofing & Maintenance installs asphalt shingle roofing throughout Portal, 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. Portal Roofing & Maintenance follows the exact specs that keep the manufacturer warranty valid.
Our Shingle Roofing Process
Consultation & Inspection
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 Portal home.
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.
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.
Shingle Courses
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.
