Tracey Streeter

Will and his crew were amazing! They were all very professional and did an amazing job on our new roof! Will came out and gave us an estimate within hours, said he was out 3-4 weeks and they showed up on the day they said. So punctual, communication was top notch and all questions were answered. I would highly recommend them.

Excellent! They were so wonderful to work with because they were easy to communicate with, on time and quick, very thorough, very reasonable price, extremely clean. After two days I had a beautiful roof and no evidence of them even working there because so clean. My best compliment was there commutation so clear and quick making me feel confident and informed, no guessing on my part. Very nice as well!

I called a dozen places before I spoke to Ideal Roofing. They came out same day and fixed my roof leak. The service call was fast and because the crack in my roof tiles just needed to be sealed, he didn't even charge me for his time. I would highly recommend them. Fast, kind, and no more leak, even with the following day's rainstorm. Whatever my roof may need in the years to come, I will be calling these guys.

We needed new shingles and skylights on our home and new skylights on a utility shed due to hail damage. Will and his crew did stellar work from the installation to the cleanup on both projects. Will made sure we were happy with the quality of all the products installed. Communication was easy and we honestly couldn't be any happier with the outcome. Thank you Ideal Roofing Co., L.L.C.

Our experience working with Will was awesome. He went above & beyond helping us with house repairs due to a hail storm. From being here when the insurance adjuster came to the very end when the job was completed. He was on top of all our needs & concerns. Him & his workers rate a 5 star for their excellent work & professionalism. Ideal Roofing is on the top of our list for recommendations. A big Thank You to Will & your crew!
