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."

FAMILY OWNED.

"I used this company in 2017/2018 and it was a complete disaster. Some guy named Cord/Coy fail through my roof in 4 spots leaving permanent damage and the repairs were horribly done. They damaged my HVAC and another company had to be paid to come in and fix it. I had to hire another well known roofing company to completely redo the work. The owner was not responsive or involved in communication at all. I live in Urbana il and will gladly provide photos and proof of this horrible experience to anyone that needs it. Stay clear of this company and it's poor practices. BEWARE!"

"Very high pressure sales. For your own sake have cameras rolling during sales pitch. Don’t let them make you believe that the installation is done by Erie. Totally subcontracted. Talked us into choosing them even though they were 7k higher than other roofers with the promise of higher quality service that didn’t happen, job site was a mess had to inspect gutters they were not cleaned. They came back out cleaned said it was done got back up on ladder gutters still full and found damaged siding on back of chimney. After filling with BBB repairs and cleanup were done just not worth the higher price. Price started at $26 a square for metal and $15. For fiberglass after 4 hours of sales it came down to $21 metal and $10.5 a square foot fiberglass. I surely have buyers remorse hopefully this review helps someone in their decision. Also suggest reading this [*** Link removed ***] prior to reading all the A+ ratings on BBB Also make sure proper permits were pulled they did not pull one till after the install when I questioned it. Good Luck"

Home Building questions, answered by experts

Building a new home can be more expensive than buying an existing one, depending on the housing market in your area. Many homeowners still find that building a new house is worth the investment as they can choose the exact layout they want, as well as to choose their own floors, wall coverings, appliances, and finishes. If you live close enough to the build site, you can also stop by to check on the builder’s progress, which can provide some peace of mind that the project is worth it.

How long it takes to build an in-law suite will vary by type. The time it takes to build an addition will typically be less than for completely new construction. Expect to spend about two months if you convert a basement, attic, or other existing room in your home. New structures can take up to five months, plus up to two months to receive the required permits.

Ranch and colonial-style homes are often the most affordable to build. They have a common layout with available designs that are easy to adjust in simple ways without having to spend too much on a structural engineer or architect. Both types of homes' symmetry, simple roofs, and often one or two-story plans mean they often fall in the $150 to $200 square-foot range, putting them right around average.

Modular homes can be a great investment, especially for those who find the prices of stick-built real estate too high. Modular homes are usually much more affordable because they’re mass-manufactured and then assembled on-site or delivered mostly assembled. If they’re installed properly and by professionals, they can last for between 50 and 100 years, potentially making them an outstanding investment.

Common pitfalls include underestimating the cost of site preparation, overlooking permit and utility fees, and not setting aside funds for unexpected changes. Change orders during construction can disrupt your budget. It’s best to plan a detailed budget, obtain multiple quotes, and include a 10% to 15% contingency fund for unexpected expenses.
