Roofing reviews in Sunnyvale

    They responded to my inquiry right away on a Saturday and offered to stop by for a free estimate. They arrived when promised, quoted a fair price, and did the job on the spot. I got up on the roof myself to inspect their work and they did an excellent job.

    As repeat customers, we initially worked with Signature Roofing about 15 years ago to replace an old wood shake roof on our first home. At the time, we found them to be very professional, from the moment we received the quote through the entire re-roofing process. They were very honest, punctual, and did a wonderful job of installing a high quality roof with no problems during the following rainy season - no leakage at all, even around three skylights. They also did a very thorough job of cleaning up after the project was completed. But what really stood out was the building inspector's comments when it came time to sell our home. The building inspector said that the roof installed by Signature was probably the nicest roof he had ever seen, and he gave them an A+ for their quality and workmanship. Our experience with Signature was so positive that when it came time to re-roof our second home, we didn't bother to get quotes from any other roofing company. Again, we found both William and George to be very professional, honest and punctual. We met with William first, who patiently took the time to walk around the house and answer all of our questions and concerns. We discussed ventilation, dry rot issues, the different types of roofing materials out there, whether or not to replace the gutters or add more insulation, and even rodent issues which other neighbors around us have had. William was very honest. He told us what we did or did not need and didn't try to push more expensive products or services with us. Both William and George were very good at responding to our emails within the same day with answers to any additional questions and concerns we had. Once the re-roofing project started, George kept us updated with daily progress reports. After the installation, they did an extremely thorough job of cleaning up. Our gardener was very impressed, stating that in the 30 years of working as a gardener, she has NEVER seen such a thorough clean-up job. Our new roof looks beautiful, and we are extremely happy with the re-roofing job by Signature Roofing. We highly recommend them!!!

    Mike Simons ( was on time for the price quote and the members of our Church accepted his bid. His crew was on time for the gutter work, as well as cleaning and painting and it was completed on schedule. The work met all our expectations, as does the warranty. He also gave our Church 2 follow up free gutter cleanings.

    Gutter Pros was knowledgeable, prompt, professional and did a quality job. When the amount of flashing required was more than expected, they came out a second time with more flashing and did not charge extra.

    Could not be happier with Tri-City Roofing. Had a complete re-roof and rain gutter replacement. Their crew was great. The job took a total of three days and at the end of each day they did an outstanding job of job site cleanup. The office staff was extremely informative and cooperative from start to finish.

    Cosmos work crew showed up on time to start work. Had one mixup by a supplier that pushed completion out by a day but not Cosmos fault. New gutters are great and new roof looks like it is doing promised job of reflecting heat and keeping house cooler. The replacement ceiling fan had wiring issue but that was due to crappy documentation by manufacturer and not Cosmos.

    Excellent! My Dad used Security Roofing 34 years ago(and they are still in business) which is a big plus to me. The roof that they put on in 1983 lasted until 2017 with no leaks, ever! Just recently with the high winds did I start to find shingles coming off. Security Roofing is family owed, they have a great crew, they show up on time, clean the mess, do the job in a timely manor and the best thing...they are HONEST!!! I had many estimates that ranged from 11.000 to 29,300. For my size roof I thought it would cost between 11,000 to 15,000 Bob's estimate was a little higher than the lowest one I got but because I knew the last roof they installed last so long and my Dad liked the job they did 34 years ago I went with them. I made a good decision and I got a beautiful new roof, gutters and drain pipes. JOB WELL DONE!!!!

    The work was done very professionally (very careful to stack and not break tiles that were removed). Didn't notice a single nail, scrap metal, or anything after they were gone. I'm assuming the roof doesn't leak any more as we haven't had rain since the work was done.

    They did excellent work, particularly Jesus and his sons who did the majority of the job. They paid a huge amount of attention to detail to make sure everything was done right. The job did take a little longer than forecasted, mainly due to a faulty insulation blowing machine and an overly patched tube. Cosmos Roofing quickly fixed a small amount of "collateral" damage done to some brickwork in our front yard. I was extremely happy with this response, since most contractors are loathe to fix things they break in the process of doing a job. Additionally Cosmos had the lowest bid of the 4 companies we had bid on the job. I highly recommend Cosmos Roofing.

    The team was very professional and communicative, they did everything on
    time and passed all inspections. We asked to add a few more items to
    the work while the project was running and they responded and did the
    necessary adjustments very quickly and for I think was a very fair
    price. I will recommend them to my friends and to anyone that is looking
    for a reliable contractor. Good job.
