    I am so delighted with my beautiful new roof. When my estimator (Sean) came to the house he was friendly & knowledgeable. Sean explained everything to me and stated that they would start in a week or two, weather permitting. The project … More manager (Daniel) arrived with the work crew lead by Javi at 8am. They set everything up in a short time and proceeded to start the job. I couldn't believe how efficient and hard-working the crew was. The old shingles were off and sheeting replaced and disposed of. The tarps came down and shingles went on. The clean up was VERY impressive. Not a single scrap left behind- they even used the blower on the grass and walkways. I went to take a look and was overjoyed! What a great job and what an amazing company- A great big "Thank You" to Sean and they whole crew!

    CRS crew did a wonderful job on the garage roof. They are very professional, fast but efficient at what they do. The clean up was spectacular. There was a crew of at least 7 to make it a one day job.

    Tyler and crew led by Wolf did a fantastic job! The crew started at 8am, peeled off the steel roof, the two layers of shingles under neath, replaced 21 sheets of OSB , layed down the new shingles and pulled out of our driveway at 9pm that … More night. From start to finish the whole experience was smooth and efficient. Thank you very much for your professionalism.

    Our trim on our metal roof blew off in a wind storm and this company did a great job of repairing it for us. We didn't have to wait long for the repair either. They were always on time and reliable! Great job! I would definitely call … More them again!

    This is probably the best roofing company that I have ever used. Mike Clop (owner) was excellent with scheduling, communication and materials.
    Nick Tomasoni, (job supervisor) was amazing at directing his crew and overseeing the work.
    … More He kept me informed and up to date on the progress of the project throughout the day. They removed all of the existing roofing materials on the 32 square roof, replaced existing sheathing that was deteriorated, and installed the new architectural shingle roofing system in one day. Cleanup was fantastic.
    Highly recommend these folks to anyone. Kudos to Nick and crew.
