Our Services
Full-service roofing contractor in Thornton — from asphalt shingle roof replacement and emergency hail damage repair to metal roofing, flat roof systems, and gutter installation. Every project is installed by manufacturer-certified crews with workmanship warranties.
Trusted by homeowners and businesses across Thornton.
We get on the roof, take photos, and give you an honest assessment. If you don't need work, we'll tell you. No charge, no obligation, no high-pressure sales pitch.
Only 3% of roofers earn this certification. It means we can offer the Golden Pledge warranty: 25-year workmanship plus 50-year materials. Best warranty in roofing, full stop.
GAF Master Elite, Owens Corning Preferred, CertainTeed SELECT ShingleMaster. We carry certifications from the big three. That means factory-trained crews and the best available warranties.
Storm damage? We work with your insurance company directly. Free inspection, Xactimate documentation, adjuster meeting on-site. We fight for full replacement when your roof qualifies.
Simple Process
We climb up, walk the entire roof, and document what we find with photos and measurements. Takes about 30 minutes. You'll see exactly what we see.
Our Thornton estimator builds your proposal same-day in most cases. Includes material options, warranty comparison, and a realistic timeline for your specific roof.
Dumpster arrives at 7 AM. Tarps on the landscaping. Tear-off starts immediately. New ice and water shield, underlayment, drip edge, shingles, ridge vent. All in sequence.
We register your GAF, Owens Corning, or CertainTeed warranty directly with the manufacturer so it's active from day one. Your workmanship warranty from us starts the same day.
Verified Reviews
"Got three quotes for a roof replacement. Thornton Roofing & Maintenance was the middle price but the only one who actually got on the roof and showed me photos. Everyone else just eyeballed it from the driveway."
"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."
"Had them install a ridge vent to replace the old box vents. Attic runs about 15 degrees cooler now. Should've done it when we got the roof but better late than never."
