    Roof Repair
    $4,300

    I had a terrible leak coming from the roof after a storm and hence called up Cooper Roofing out of desperation. They offered a swift response and did the fix quickly. The leak issues have been handled professionally and it was nice to interact with these chaps. I will be using their services more for roofing-related worries.

    I would highly recommend Cooper Roofing to anyone who has to replace their roof. They placed before me the best options for a roof replacement and I only had to make a choice. They did the core replacement flawlessly but that was not all. They helped me out with the insurance and made sure that I got the best deal. I am grateful to them for helping me out with the complex process of a roof replacement.

    I am extremely pleased with the friendly professional service on offer from Cooper Roofing. They had arrived for some basic roof repairs and did the work smoothly. They did the roof repairs without creating much noise and kept me informed at every stage. I will be using their services more in the future.

    I use the services of Cooper Roofing to do any form of inspection, repair, and even replacement work necessary for my roof. They have been my roofers for the last 25 years and I have found them to be a professional, reliable team. I intend to continue the association with them and would also be referring them.

    Roof mobile home
    $8,000

    Cooper Roofing put a new roof on our Mobile Home. Less than a year later we had a bad leak into our family room and bedroom ruining the ceiling. It was determined that the flashing from roof to awnings was in very bad shape and needed at the least sealing or better replacing. After numerous calls a guy came and sealed about 2 feet but the flashing is about 25 feet long.Then Cooper Roofing said they don't work on flashing to awnings. We had to sue ,We won they tried to vacate the judgement they lost they appealed they lost. We reported to Contractors board and they finally paid. I would not recommend !!!
