Complete Shingle Roof Replacement and Deck Repair

On August 26, 2025, the Roof Repairs CA team completed a comprehensive shingle roof replacement at 4600 Viro Rd in La Cañada Flintridge, CA 91011. The project began with a full tear-off of the old roofing system, revealing multiple issues with the existing structure. Large areas of the roof deck were weakened by water damage and rot, exposing the insulation and leaving the home vulnerable to future leaks.

Our skilled crew removed all compromised plywood and reinforced the framing before installing new decking. During this process, safety measures were put in place, and all work was performed under strict OSHA compliance. One notable section near the roof’s edge had a large open cavity, which we repaired using fresh wood sheathing and secure nailing patterns to ensure a solid base.

Once the decking was restored, we installed a CertainTeed DiamondDeck synthetic underlayment system, which offers superior moisture protection and long-lasting durability. The team also inspected and improved the flashing systems around all roof penetrations—including the home’s skylights—to prevent future water intrusion. Gutter guards were installed to reduce future maintenance and leaf buildup.
