Residential & Commercial Roofing in Guilford
Guilford Roofing & Maintenance handles every roofing job from a single-shingle repair to a full commercial re-roof. Here's what we do in Guilford.
Roof Replacement
Full roof replacement starts with a complete tear-off down to the deck. We inspect every board for rot or soft spots. In Guilford, we find decking damage on about 30% of tear-offs. Damaged sections get replaced with CDX plywood before anything else goes on. Then we build up: ice and water shield in valleys and at eaves, synthetic underlayment across the full deck, new drip edge on every edge, starter strip, field shingles, hip and ridge caps, and ridge vent. Dumpster, permits, and cleanup included.

Improper step flashing is the leading cause of roof leaks at wall-to-roof transitions. Step flashing needs to be woven between shingle courses with each piece extending 4" above the shingle exposure. We see Guilford homes where the last roofer used continuous L-flashing or just caulked the gap. That always fails. We tear it out and install proper step flashing with a kick-out diverter at the bottom per IRC R905.2.8.3.

After every major storm in Guilford, out-of-town companies flood the area offering free inspections. They're not all bad, but many are. We're local, we're licensed, and we'll be here to honor the warranty. Storm chasers won't be.

New construction means we get to do everything right from scratch. No compromises, no working around someone else's mistakes. Ice and water shield where it belongs, properly lapped underlayment, correct nailing patterns, and ventilation sized to the space. That's a roof that lasts.

Standing seam metal with Kynar 500 PVDF fluoropolymer finish. The gold standard for color retention and chalk resistance. We install Sheffield Metals and McElroy Metal panels in 24-gauge Galvalume steel. UL 2218 Class 4 impact resistance (qualifies for insurance discounts in most Maine markets). UL 790 Class A fire rating. Wind uplift rated to 140+ mph per ASTM E1592 testing. Concealed Z-clips allow thermal expansion without stress on fasteners. That's what makes standing seam leak-proof.

Asphalt shingles cover more homes in America than every other roofing material combined. There's a reason. They're affordable, they look good, they last 25-50 years depending on the grade, and they come in dozens of colors and profiles. Our Guilford crews have installed thousands of shingle roofs and we know the product better than most roofers in the state.

The number one cause of flat roof failure is ponding water. Standing water that doesn't drain within 48 hours after rain. We solve ponding by installing tapered insulation systems that create positive slope to drains, scuppers, or roof edges. Minimum 1/4" per foot of slope eliminates standing water.

TPO is our most-installed commercial membrane in Guilford. 60-mil thickness, hot-air welded seams, mechanically attached or fully adhered over polyiso insulation. The weld is stronger than the membrane. 15-20 year manufacturer warranties depending on system build-up.

We hang gutters with hidden hangers screwed into the rafter tails or fascia board every 24 inches max. No spike-and-ferrule, no exposed hardware. Proper pitch is 1/4" per 10 feet toward each downspout. Too flat and water sits. Too steep and it looks wrong.

Roof inspections are free for Guilford homeowners. No strings, no obligation to hire us for repairs. If your roof is fine, we say so. If it needs attention, you get an honest assessment of what's going on and what it'll cost to fix.

When a tree goes through your roof at 2 AM, you need someone who answers the phone and shows up with a truck full of materials. Call (877) 349-1553. We handle roofing emergencies in Guilford 7 days a week, including holidays.

Replacing an old leaking skylight is often cheaper than trying to repair it. New units from VELUX have Low-E laminated glass, argon fill, and No Leak guarantees when installed with the manufacturer's flashing system. Our Guilford crews replace skylights in a single day.
