"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."

"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. "

We pride our company on reliability, great communication, integrity, and quality work. We are experts in our trade and will do our best to keep you as educated as we can on your particular task or project. We look forward to earning your business!

"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."

FAQs for flat, foam, or single ply roofing installation and replacement projects in Knightsen, CA

Many roofing pros point to PVC as the top performer on flat roofs thanks to its tough seams and long-term waterproofing. A properly installed PVC membrane can last 30 years or more, resisting ponding water and harsh weather with ease. You will pay more up front than you would for EPDM, but the added durability often translates into fewer repairs and a lower cost per year of service.

Yes, a rubber roof is an environmentally friendly choice. Most rubber membranes contain recycled content and can reflect heat, which helps trim cooling bills in hot weather. Manufacturing has a lighter footprint than many traditional materials, and the long lifespan means fewer tear-offs headed to the landfill. If sustainability is a priority, ask your roofer about brands that carry third-party eco-certifications and confirm they meet local environmental standards.
