    Did You Know?

    "Flat" Roofs Aren't Actually Flat

    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.

    Signs of Drainage Issues

    • Water still visible 48+ hours after rain
    • Visible dirt rings or algae growth
    • Sagging areas on the roof surface
    • Water stains on interior ceilings

    Who in the world does that? Cornerstone does.

    Showed up at 6:15 am, done by 2:15 PM. Same day. Not one nail left behind. As I walked around I noticed they had even painted the vent stacks to match. A++ in my book!

    All we did was make a claim. Cornerstone handled everything.

    We had wind damage and all we had to do was call our insurance. Every phone call, every email, down to the silliest questions. Knowledgeable and professional from start to finish.

    "Cornerstone is a very professional company with excellent work ethics. They really care about providing excellent service and doing a quality job. They arrived on time and spent a great deal of time providing protection for my house and plants/flowers. The workers were friendly and responsive to any of my questions. The job was done in a day and their clean up after the work was done was very detailed and complete. They have been back to my house to check on their work and to make sure I was satisfied. Any concerns/questions I had were addressed immediately. I have had numerous compliments on my new roof from friends and neighbors. I would definately recommend Cornerstobe Roofing."

    "Hands down the easiest insurance roof claim experience I've ever had! With his experience and expertise, the owner himself made the entire insurance experience a complete breeze. After that the rest of his team stepped it up and made the scheduling and completion of work happen so smoothly — they had the job completed with a bow on top by the time I even thought to call for an update! There's no doubt about it, I'll be calling Cornerstone Roofing and Siding for any future needs."

    "We had a fantastic experience working with Cornerstone Roofing and Camen. He handled everything from start to finish — helping us replace our roof, filing the claim with our insurance company, and working diligently to get everything approved. Camen was extremely thorough, and his support staff was excellent. Even the roofing crew did a great job, showing skill and professionalism throughout the project. We're very happy with the new roof and also love the new gutters they installed."
