CAT Contracting, Inc. is a national restoration company which operates two divisions. The residential catastrophe division facilitates the sales and restoration processes for homeowners after catastrophic storm events. The Commercial Division services large low slope membrane systems including but not limited to TPO, EPDM, Spray Foam, PVC, Metal and Hydro-Stop

"The original project manager was good. He installed the roof, had a few hiccups, but I was satisfied until 1 1/2 years later when I got 4 leaks. Additionally, some aluminium was supposed to be installed and it still hasn't been installed. I have been calling since March 2019 and still no one has come out to fix the leaks. I only have a couple of months left until warranty expires which I'm figuring they are waiting for. I've called & asked the owner Matt to call me, b ut 5 days later and still no call. A roofer is only as good as his repairs. My advise is don't use Cat. They have no one within 50 miles to repair my roof. I'm very disappointed as I first thought they had done a good job. I had seen reviews where the owner was very responsive, but not to me."

Hail Damage Specialist, family owned since 1993 that operates under a NO PRESSURE SALES mentality. Most roofing projects completed in 1-2 days. Insurance claims welcomed. A+ with BETTER BUSINESS BUREAU. Fully licences and insured.

"Heinz Roofing just finished installing a beautiful new roof on our house. We were impressed by the quality of their work and their attention to detail. Even though it was not called for in the contract, they replaced the old drip edge with a new one that matched the color of our gutters and trim, while the old one did not. They arrived by 6AM and worked until dusk to finish the job and make sure that all debris was cleaned up and the yard left in good order. We highly recommend Heinz Roofing to anyone needing a new or replacement roof."

Roofing questions, answered by experts

Shingle damage comes in many forms, and the damage usually depends on the wind speed and the shape of the roof before the winds. Typically, when shingles are damaged by wind, they become torn, creased, or detached from the roof. Some might go missing entirely. More extensive roof damage might occur if a tree branch or other debris has fallen onto the roof as a result of the windstorm.

Depending on the condition of your roof, you may be able to add flashing to it. If you’re looking for a way to maintain its integrity while saving some money, you should ask a roofing pro if this is an option. Keep in mind that if your roof is in poor shape, a full replacement may be necessary before flashing is installed.

The best roof replacement type depends on your budget and your particular climate, as well as your personal aesthetic. But in general, asphalt shingles are the best roof replacement type for homeowners looking for durability at a budget-friendly price. Asphalt shingles are the most common roofing material—cost-effective, easy to install, lightweight, and the perfect choice for handy homeowners.

If a home isn’t properly winterized, the pipes can freeze and burst, causing flooding and massive property damage. It can also leave your house susceptible to pests, which can infest it and cause significant damage. Winterizing a home can prevent many potential issues and save you money on costly repairs.

If you’re looking for a cost-effective alternative to a traditional chimney, consider having a dummy chimney installed. Dummy chimneys can either be aesthetic-only or fully functional and can be installed on both new and older homes. Whether installed to match your neighborhood’s aesthetic or to vent your chimney, dummy chimneys are made out of a Glass-Reinforced Plastic (GRP) core, then covered with brick or stone slips to look like a traditional chimney.
