"We had our roof replaced with GAF shingles by American Cool Roofing and the whole process was excellent. The crew was professional, efficient, and finished the job on time. The roof looks amazing and the quality of the work is very noticeable. Hailey provided outstanding customer service and kept us informed throughout the entire project. Highly recommend them!"

""Hey there, just wanted to share my experience with Platinum Roofing & Retro-Fit.They did a solid job on our metal roof. The team was friendly and made sure we knew what was going on every step of the way. Our roof's looking sharp now! Also, when it started raining unexpectedly, they came out and tarped the roof to avoid any extra damage. If you're looking for roof work, they're worth reaching out to. Thanks, boys!"

"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"
