Our roof replacement process begins with a comprehensive inspection and a detailed, free estimate. We assess the condition of your decking, flashing, and underlayment, which is crucial given our local weather. Using our certification from top manufacturers, we help you select materials suited for durability against coastal moisture. Our experienced crew then manages the entire project, from safe removal of the old roof to meticulous installation and a thorough cleanup, ensuring your new roof is built to last.

Yes, issues like roof valley leaks and lifting flashing are very common in San Mateo due to wind, heavy rain, and thermal expansion. These areas are critical for water drainage. We address this by first conducting a precise leak detection to find the source. For valleys, we often repair or replace the metal lining or shingle weaving with superior sealing techniques. For flashing, we resecure or install new, corrosion-resistant flashing integrated properly with the roof system to prevent future lifting and water intrusion.

Our deep local experience, spanning over 50 years combined since our founding in 2004, is key. We don't just install roofs; we install roofs for San Mateo's specific conditions. We factor in local building codes, typical weather patterns, and architectural styles. Our long-standing relationships with material suppliers and a network of trusted references mean we source quality materials and stand firmly behind our workmanship, ensuring your new roof is a reliable, long-term investment for your home.
