"Needed to have our roof replaced. Lifetime Roofing is great! Gui from Lifetime stopped by the same day I called in for an estimate, and he was able to get us a very competitive price. Gui regualrly checked in to provide us updates on the status (permitting, install progress, etc.) and to see if we had any questions or issues. The crew was fantastic. Clean and quick. The best part? The City of Mt. View told Lifetime to install 20 vents on a 2,500 square foot roof!!! Lifetime spent time with the inspector and got that down to 5 vents and ridge vents. Very helpful! Overall, a wonderful experience."

Cobex Construction Group is your 5-Star trusted exterior contractor for Roofing , Siding and Windows. We are a local family owned home improvement company with a combined 30 years of experience in home improvement and construction. Our company principle is "people before profit" we believe in the saying ?Do it once, Do it right?

"I live in a home owners association. One of the roofers got a speeding ticket. The project manager said the Company would pay the fine. A month and two emails later radio silence and no effort to pay the fine. Can't judge the workmanship since it hasn't rained enough to test the roof. However, given the companies failure to live up to the representation of the project manager and their failure to respond to my emails over such a simple issue, I anticipate problems will be forthcoming."

CAP INC is dedicated to providing our customers with the best quality and craftsmanship. We are here to build relationships with our customers and communities and to provide our employees with a great place to work. We look forward to working with you.

"This roofing job started off bad and continued to the finish. I wanted a professional with a few requirements. Be careful of original structure as it is prefabbed. The workers punched twelve holes in sheeting removing old roof material, requiring sheeting overlay. I requested that roofing nails not protrude through roof in patio area. They were protruding through the entire area. They left refuge sitting on the side of the driveway until I asked to have it removed. The one-week job turned into a two-month Odessey. The job was obviously a side job, piece-mealed together with little supervision little supervision. I am not confident the roof will not fail. prematurely fail. "

"After 28 years in a newly built home, a few weeks ago I noticed a leak in the roof following California storms. Out of all the roofing companies I contacted in panic, Rafael from Titanium Roofing was the first one to show up with a drone. He gave me comprehensive report with pictures and a competitive pricing. His team promptly patched multiple leaks, replaced a few tiles and even cleaned up the gutters. Then he came back with another crew to paint the inside of a high ceiling, all with a big smile. I therefore recommend him and his company without hesitation for any roofing jobs."

Roofing questions, answered by experts

A gambrel roof and a mansard roof are similar in that they are both hipped roofs, meaning they have double slopes—one steep and one more gradual above the steep slope. The difference is that a gambrel roof has a double slope on only two sides of the structure, whereas a mansard roof has a double slope on all four sides.

You can replace a roof in the winter, though it’s not the most popular time to do so. The biggest drawback of winter roofing work is the weather. Snow and ice make for dangerous, slippery working conditions. Plus, shingles can only be installed in temperatures above 40 to 45 degrees. 

The best time to replace a roof is in the spring or fall when the weather is mild. However, you can likely save some money by booking the job in the winter off-season, when roofers have more availability. 

Depending on the condition of your roof, you may be able to add flashing to it. If you’re looking for a way to maintain its integrity while saving some money, you should ask a roofing pro if this is an option. Keep in mind that if your roof is in poor shape, a full replacement may be necessary before flashing is installed.

It’s not normal for a chimney to leak even a little bit during heavy rain. A chimney in good condition will keep rain from seeping into the chimney or house, so if you notice a small leak during a rainstorm, it’s time to call a pro for inspection. There could be damage to the flashing, chimney crown, or flue liner.

Flat roofs are cost-effective, offer usable space, and are easy to maintain. Foam and single-ply materials provide excellent insulation and durability.
