Our Services
Our Roofing Services
Professional Roofing solutions for residential and commercial properties in Derry.
Roof Replacement
Our Derry crews tear off and replace 15-20 roofs a month. That kind of volume means tight installs, clean job sites, and no wasted time. Most homes are done in a day. Two-story steep-pitch jobs take two.
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
We work with every major insurance carrier. State Farm, Allstate, USAA, Liberty Mutual, Farmers, Nationwide. Our supplement team knows Xactimate line items and fights for full replacement when your roof qualifies.
New Roof Installation
New construction roof installation following IRC Section R905 and local Derry building code amendments. We calculate ventilation per IRC R806 (1:150 ratio reduced to 1:300 when 50% is within 3ft of ridge. Synthetic underlayment per ASTM D226, ice barrier per ASTM D1970 at eaves in freeze-thaw climate zones. Manufacturer-certified installation locks in the full system warranty.
Metal Roofing
We install 24-gauge and 26-gauge standing seam in Galvalume and pre-painted steel. Concealed fastener system means nothing's exposed to weather. Panels lock together at the seam and clip to the roof deck.
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 Derry crews install Timberline in the full system configuration to qualify for Golden Pledge warranty. ASTM D3462 and D7158 Class H certified.
Flat Roofing
Commercial flat roof replacement in Derry 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
Your commercial roof is protecting your inventory, your equipment, and your employees. We do annual inspections for Derry business owners. Catch small problems before they become $50,000 problems.
Gutter Installation
Improperly sized gutters cause fascia board rot and foundation erosion. We calculate gutter capacity using the rainfall intensity formula: roof square footage x pitch factor x rainfall rate (inches/hr for Derry). Standard 5" K-style handles 5,520 sq ft of effective roof area. Bigger roofs or steeper pitches need 6" gutters with 3x4" downspouts. We hang with hidden hangers screwed into rafter tails every 24".
Roof Inspection
We climb up, walk the entire roof, and document what we find with photos and measurements. Takes about 30 minutes. You see exactly what we see. No mysteries, no scare tactics.
Emergency Roof Repair
Storm damage, fallen trees, sudden leaks. We handle all roofing emergencies in Derry. First we stop the water, then we fix the cause. Emergency response available 7 days a week.
Skylight Installation
A skylight installed wrong will leak. The flashing has to integrate with the shingle courses. Step flashing on the sides, headwall flashing on top, and a sill pan underneath. We use manufacturer flashing kits because they're engineered to work with the skylight frame.
