"The project went even better than I thought it would. We had a hard time finding someone who would work on fixes to existing roof. Most wanted to do full replace. Northern California roofing came very quickly to do estimate and was able to start work on roof within a week. Great turn around. The work was very well done and makes us feel like we have a new roof. Can’t wait for next rain!"

"The team from Titanium Roof Innovations company recently did a great job preparing our roof for installation of solar panels. The work included removing existing tiles and underlayment from the roof, doing necessary prep work like replacing damaged plywood, installing new metal valley flashing at all roof connections and T-tops and vent caps on all exhaust pipes, and applying water-resistant mastic in all valleys. They installed peel-and-stick underlayment designed for tile roofing which provides advanced water barrier before placing back the tiles. Finally, they painted all flashings and vents with Rust-Oleum to match the roof color and cleaned the roof with a power washer. They left the working area in a neat clean state removing all debris. The team manager, Julian Mattos, was very efficient and responsive to our requests. Importantly along with a great service the Titanium Roof Innovations company provided a very competitive price for their work and the work has been completed on"
