Roof Replacement

We handle the whole replacement from permits to final inspection. Our Alton Bay office pulls the permit, coordinates the dumpster, runs the crew, and schedules the building inspector. You sign the contract and we handle the rest.

roof repair
SAME-DAY

Roof Repair

After we fix your roof, we send you before-and-after photos and a written warranty. If it leaks again from the same spot within 5 years, we come back free. That's the deal.

storm damage repair
LICENSED

Storm Damage Repair

Hail, wind, fallen branches. New Hampshire storms do real damage to roofs. We respond within 24 hours, tarp exposed areas to prevent further damage, and start your insurance claim with a detailed inspection report.

new roof installation
TOP RATED

New Roof Installation

Atlas Pinnacle Pristine shingles with Scotchgard algae protection. Ideal for New Hampshire humidity. We also install Tamko Heritage laminated shingles for budget-conscious builds and Malarkey Vista AR with Flexor SBS polymer-modified asphalt for high-wind zones. Your installer should match your material choice to your climate, not just your budget.

metal roofing
GUARANTEED

Metal Roofing

Metal roofing in New Hampshire makes sense. It reflects heat, handles high winds, and sheds hail better than shingles. We install standing seam, corrugated, and metal shingle panels.

shingle roofing
INSURED

Shingle Roofing

GAF Timberline HDZ architectural shingles with StrikeZone nailing area. The highest-selling shingle in North America. Impact-rated to UL 2218 Class 4 when installed with the full GAF Roof System. Our Alton Bay crews install Timberline in the full system configuration to qualify for Golden Pledge warranty. ASTM D3462 and D7158 Class H certified.

flat roofing
FREE ESTIMATE

Flat Roofing

Commercial flat roof replacement in Alton Bay starts with a core sample to check the existing insulation. If it's waterlogged, everything comes off. If it's dry, we can sometimes overlay. Saves you $2-$4 per square foot.

commercial roofing
SAME-DAY

Commercial Roofing

TPO is our most-requested commercial membrane in New Hampshire. Reflective, energy-efficient, and it welds together at the seams for a watertight bond. We install 60-mil and 80-mil systems with 15-20 year manufacturer warranties.

gutter installation
LICENSED

Gutter Installation

If your gutters overflow during rain, they're either clogged, undersized, or pitched wrong. Sometimes all three. We'll assess the issue and fix it. Might be a cleaning, might be a replacement.

roof inspection
TOP RATED

Roof Inspection

Our Alton Bay roof inspections cover shingles, flashing, pipe boots, ridge vent, soffit, gutters, and decking condition. You get a written report with photos. If nothing's wrong, we tell you that.

emergency roof repair
GUARANTEED

Emergency Roof Repair

After we tarp and secure your roof, we document everything for insurance purposes. Photos, measurements, damage descriptions. Your adjuster gets a professional report, not a handwritten note.

skylight installation
INSURED

Skylight Installation

VELUX FS fixed skylights and VS vented skylights installed with EDL flashing kits for profile roofing. The flashing integrates with your shingle courses per IRC R903.2 weather protection requirements. We cut the opening, frame the curb with doubled 2x lumber, install the skylight with factory sealant, and weave the flashing into the existing shingle field. Leak-proof when done right. And we do it right in Alton Bay.

"Went with the Owens Corning Duration shingles in Estate Gray. The SureNail strip is legit. You can see each shingle is locked down tight. Happy with the choice."

"They replaced our gutters along with the roof. Seamless aluminum, everything matches. No more overflow when it rains hard. Wish I'd done this years ago."

"Asked for a second opinion because another company said I needed a full replacement. Alton Bay Roofing & Maintenance said I only needed valley flashing repair and some shingle replacement. Saved me about $14,000. I trust these guys."

FAQ

Frequently Asked Questions

Catch the water with a bucket, move valuables out of the drip zone, and call us at (877) 586-1316. Don't get on the roof yourself. It's dangerous and you probably can't fix it permanently anyway. We respond to emergency leaks within 24 hours in Alton Bay and tarp the area to stop further damage.

Yes. We offer 12-month same-as-cash, low-interest plans up to 144 months, and no-money-down options through GreenSky and Hearth. Credit approval takes about 5 minutes. A new roof is a major expense. Financing lets you get it done now without draining your savings.

There's no single "best" shingle. It depends on what you need. For warranty coverage, GAF Timberline HDZ with Golden Pledge is the best in the industry. For wind resistance, Owens Corning Duration with SureNail locks down tight. For value, CertainTeed Landmark or IKO Cambridge give you solid performance at a lower price point. We carry all of them.

The shingles carry the manufacturer's warranty. Typically 30-50 years for architectural shingles. Our installation warranty covers any defects in our workmanship. If something goes wrong because of how we installed it, we fix it at no cost. Both warranties are in writing and we provide them at the final walkthrough.

Most residential roof replacements in Alton Bay cost between $8,500 and $24,000. The price depends on your roof size (measured in squares, where 1 square = 100 sq ft), pitch, accessibility, and material choice. Architectural shingles are $350-$550 per square installed. We give free estimates with exact pricing.
