"Mr. Clark quickly provided an easy to understand quote and politely answered all of our questions regarding the roof repair. He adjusted his schedule to fit in our repair before the next rain. The crew was professional and performed a quality repair. We would highly recommend RC Roofing and would definitely use them again."

"Initially we called Protecta Roofing to get our roof inspected. Even though we currently did not have leak issues we thought it wise to have the roof inspected as the ceramic tiles were close to 30 years old. Mario was prompt in responding and coming out to inspect. We were informed of 10 broken tiles. Our decision was to have the tiles replaced and power wash the roof to remove algae which included applying an organic sealant product. After a couple weeks of failed attempts to obtain an estimate from Mario I was in touch with Edith, the company sales manager. From then on the communication and process went smoothly. Edith and crew were a delight to work with. Her knowledge of the work to be done and concern for my satisfaction were impressive. In addition to repairing the broken tiles, our solar panels were cleaned along with painting the pipe flashings. Because everything looked so clean we decided to have Protecta power wash our driveway and side walkways, which are also cleaned with the organic algae solution. The work done was outstanding!"

"Start to finish the entire roof replacement was about 2 days, which is impressive with how great it looks. Now some people might think that it’s expected for the roof to look really good because it’s brand new but I drive around neighborhoods all the time and I see brand new roofs that don’t look great…We added in some vents for the attic (with their suggestion), which I really didn’t think would make such a big difference, but I gotta tell you they have. The temperature difference inside my home has been noticeably different. overall, I can’t imagine going anywhere else in the future for any issues we may have and I will definitely be referring them to all my friends and family."

"Very nice, polite and efficient. After inspecting the roof and chimney flashing Tony told me my roof was actually very well done and in good shape, and that in his opinion the source for water leaking into my home was due to a rusted out chimney case cover and termination cap (I got those items replaced as suggested and my problem was solved). I had actually called two companies to get an analysis and quotes to fix the problem. The other company told that my relatively new roof should be ripped up and replaced in that area of the roof. I appreciate the professional and honest approach of Great Western and they will be who I will use in the future when it does come time to replace or repair my roof."

"Zenith was easy to work with and they did great work. I received three different quotes to remove and install new gutters around my house. Zenith was the only company that was able to provide an estimate without physically visiting the property, their rates were better than the other estimates I received, and they completed the work on time and within the budget. I would use Zenith for any future roofing needs and highly recommend them to others."
