Best for: Large flat roofs, cold climates
Durable synthetic rubber membrane known for its longevity and versatility. Black surface absorbs heat, making it ideal for colder climates.
Best for: Buildings with rooftop equipment
Multi-layer system with reinforced fabric for enhanced durability. Excellent for roofs with foot traffic and HVAC equipment.
Best for: Industrial, agricultural, retail
Standing seam and exposed fastener systems for commercial and industrial applications. The longest-lasting option available.
Every commercial "flat" roof has a slight slope, typically ¼ inch per foot, to allow for proper drainage. This prevents ponding water, which is the #1 cause of flat roof failures.
When we install or repair commercial roofs, we always verify proper drainage. If ponding water is an issue, we can install tapered insulation or additional drains to correct the problem. After a hailstorm or high winds, our storm damage roofing team can document the loss for your insurance carrier.
No guesswork. No surprises. We guide you from the first call to the final walkthrough.
We come to you, get up on the roof, and document everything with close-up and drone photos. Prefer nobody walking your roof? We can inspect it entirely by drone.

A reflective TPO or metal roof can reduce cooling costs by up to 25%. For large commercial buildings, that means thousands of dollars in annual savings.
Energy-efficient roofing pays for itself over time through reduced utility costs and extended HVAC equipment lifespan.
Schedule Free Inspection
"We used Cornerstone for a roof and gutter replacement and had a very positive experience. The entire process was trouble free. A few things that stood out; great communication throughout the entire process, the laborer's care for our property, no clean up afterwards, and the finished product looks great. Would definitely recommend."

"The owner who came out to inspect the roof was very professional, friendly , took pictures of roof and explained everything very well. His crew is awesome! Very professional and cleaned up everything when done. I highly recommend this business! Prices were less than I had expected."

WHO IN THE WORLD DOES THAT? Cornerstone roofing does.
Showed up exactly when they said they would (6:15 am) sorry to my neighbors. They were done by 2:15 Pm.YES that same day! … they had a guy cleaning up as the crew was working. not one nail or plastic left behind.
Seeing them work was like watching a well-oiled machine!
Their no-risk inspection revealed multiple pieces of wind damage to my shingles. From start-to-finish, the process was smooth, detailed and professional. The team who removed my shingles and installed the metal was amazing!
Comments from friends and family say it looks like a new house.
Cornerstone roofing did an absolutely amazing job on our home’s complete exterior transformation (roof, gutters, siding). … We are so pleased, and highly recommend them to anyone in need of an excellent, reliable company.
