“My wife and I want to thank you for all your help, performance and unprecedented 20 year transferable guarantee. We researched several roofing contractors. We inspected many homes, talked to references, and looked at contract details and guarantees. We found the best value, attention to detail, and guarantee was with Cosmos Roofing. They did a great job, at a great price with a great guarantee – a perfect combination.”
P. & J. B. Los Altos  
“Cosmos Roofing reroofed our Eichler home 22 years ago. Recently, in 2009 they reroofed it again saving the existing foam insulation underneath, and giving us another reliable and attractive tar & gravel roof with a 20 year transferable guarantee, white gravel and no periodic maintenance needed. Rich Cosmos was extremely helpful with impeccable attention to detail.”
A. & T. S. Palo Alto
“Alex was great to work with, and your crew did a very professional, clean and on time job. Thanks so much. We will highly recommend you.”
P. J. Belmont
“As a property manager and real estate agent, I have had a 25 year relationship with Cosmos Roofing. They have installed dozens of roofs of all types for me and my clients always using quality materials and workmanship at a reasonable price. All roofs were bid and directly managed by one of the owners making communications very easy and thorough. They always do a first class job. I recommend them to all of my clients.”
J. R. Sunnyvale
“Our new tile roof looks fantastic. Your installers were efficient, courteous and meticulous. This was the best contractor experience we have had with our home. Alex worked with us from estimating the roof to managing the crew every step of the way. Thank you Cosmos Roofing for a great contractor experience.”
M. & A. P. San Jose
“A first class job, priced right with a great guarantee. You guys were great.”
A. T. Los Gatos
“As owner of several commercial properties I have had Cosmos Roofing reroof 3 of my properties in the recent years, including a factory and medical unit rental. From start to finish their installations have been superb. They even met with the tenants to discuss all details and coordination. They installed a KOOL CAPSHEET MEMBRANE roof on our factory saving us substantial energy costs. We highly recommend them.”
J. S. Menlo Park
“The process was painless and the new roof looks great. I’m very satisfied… ”
J. B. Palo Alto, Angie’s List
“Our new Presidential TL shingle roof looks just great. Alex made us feel very comfortable taking the time to explain all the options for converting our old wood roof to high grade asphalt shingle. He explained all about sheathing options, roof venting considerations and more. We noticed a substantial reduction in energy bills with the radiant barrier sheathing and the ridge venting Cosmos Roofing installed. Thanks, Alex for taking the time to give us the ultimate roof.”
