Peak Roofing, a roofing contractor in Glens Falls, NY, holds installer certifications from both Owens Corning and GAF, two of the largest residential shingle manufacturers in North America. The dual credential gives homeowners in the region access to manufacturer-backed installation standards and enhanced warranty options on new roofs and replacements.
Founded in 2023 by owner Alex Cela, Peak Roofing serves residential and commercial customers in Glens Falls and nearby communities, including Queensbury, Lake George, Saratoga Springs, Fort Edward, Warrensburg, Schroon Lake, Ticonderoga, North Creek, and Lake Placid. As a roofing company in Glens Falls, NY, the company handles shingle, metal, and low-slope roofing, along with siding work.

Alongside its manufacturer certifications, Peak Roofing has been accredited by the Better Business Bureau of Upstate New York since September 2024 and holds an A+ rating. The company is licensed, bonded, and insured, and offers 24/7 emergency roof repair for leaks, storm damage, and impact damage. Roof replacements are backed by manufacturer warranties and a company workmanship guarantee.
“People around here don’t replace a roof very often, so they want to know it’s going to hold up through a lot of winters,” said Alex Cela, owner of Peak Roofing. “Being certified with both Owens Corning and GAF means we’re installing to the manufacturer’s spec, and the homeowner gets a warranty that actually means something.”
Manufacturer certification programs are separate from general contractor registration. Shingle makers typically review a contractor’s insurance, licensing where required, and installation training before granting certified status, and they can revoke it if standards slip. The programs are designed to give homeowners a way to identify installers the manufacturer is willing to stand behind.
For homeowners, the practical benefit is warranty coverage. Certified contractors can offer enhanced manufacturer warranties on qualifying roof systems that are not available through uncertified installers. Installation details such as underlayment, starter strips, and attic ventilation also affect whether a manufacturer will honor a future claim.
Holding two certifications gives customers more choice. Homeowners can compare shingle lines, colors, and price points from both brands without changing contractors. The same installation standards carry over to roof repair in Glens Falls, NY, including flashing, ventilation, skylight, and storm damage work, whether the job is scheduled or handled through the company’s after-hours emergency service.
“Ask any roofer which manufacturer they’re certified with and what warranty you’ll get in writing,” Cela said. “If they can’t answer that clearly, keep looking.”
Peak Roofing’s services include residential roofing, commercial roofing, flat roofing, metal roofing, roof leak repair, roof replacement, roof structure repair, storm damage repair, and siding. The company installs Owens Corning and GAF shingles, standing seam and ribbed metal panels, and EPDM, TPO, and modified bitumen systems for flat and low-slope roofs.
