Leary Roofing & Maintenance has been installing asphalt shingle roofs across Leary for 23 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
Shingle Selection
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.
Tear-Off & Deck Prep
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
Synthetic underlayment across the full roof deck. Ice-and-water shield in valleys, along eaves, and around chimney flashing, pipe boots, and vent boots. New drip edge installed at every eave and rake. Step flashing and counter-flashing at all wall transitions.
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.

Why Choose Leary Roofing & Maintenance for Shingle Roofing?
Ice-and-Water Shield Standard
Every shingle roof includes ice-and-water shield at valleys, eaves, and around penetrations. This self-adhering membrane is the last line of defense against water intrusion if a shingle fails.
Proper Flashing at Every Penetration
Chimney flashing, step flashing, pipe boots, vent boots, valley channels — every transition sealed with waterproof sealant and proper overlap. Flashing failures cause 90% of roof leaks.
Nailed to Manufacturer Spec
Every shingle nailed in the designated nailing zone with the correct number of fasteners. This is what keeps the manufacturer warranty valid and the shingles on your roof in high wind.
Full Tear-Off Standard
We strip to the deck on every shingle job. No overlay shortcuts. Your underlayment, ice-and-water shield, and flashing are installed on a clean, inspected roof deck.
