“A-1 Roofing’s Kanga Roof did two flat roofs for us.

One was already in pretty good shape, so all that was needed was some repairs and Silver Coating. That was completed in one afternoon.

The second (over the porch) was leaking badly. It needed complete removal of the old roof and replacement of some of the wood. The replace was a torch down rubber roofing. Also all of the flashing was replaced – fabricated here on site.

The work was performed in a timely manner, and the crew of four was very professional. They were here all day, and I did not notice them ever even taking a break.

The next morning, Maurice (the company owner) came by for a final inspection and to remove the debris trailer. Everything looked very good. The real test came in a few days with heavy rains – no signs of any leaks. We were very happy with the job.”

“As a Property Manager, I have performed extensive research on selecting the best contractors to perform the jobs on my building. And “Kanga-roof” was all I needed for my flat roof. Mr. Maurice inspected my roof and recommended what was the best option for me. Not only Mr. Maurice and his staffs are very knowledgeable, but also they have performed roof restoration (rather than replacing entire roof) PERFECTLY!! It was cost efficient as well. Not only their restoration material is waterproof, but also it is very energy efficient. In addition, their warranty is best there is. PLEASE DO NOT GET FOOLED by Big Companies. Not to mention, Mr. Maurice performed 3 small repairs on my other commercial roofs, and they were just PERFECT!! Mr. Maurice and their staffs are “THE BEST” there is. Give them a try and you will be a forever customer like myself.

Thank you for being there for me Mr. Maurice.”
