San Mateo Roof Replacement
Simmitri Inc. completed a full re-roof for a single-family residence located at 22 Grand Blvd in San Mateo. The project began with a complete tear-off of the existing roofing system, revealing the home’s original skip-sheathing decking beneath. Simmitri’s crew prepared the deck surface before installing GAF Tiger Paw synthetic underlayment across the entire roof, followed by new GAF asphalt shingles in a charcoal grey finish with a neatly finished ridge cap. The project was permitted through the City of San Mateo (Case #BD-2025-300638) and passed its Roof In-Progress inspection, confirming full code compliance throughout the installation.
The Challenge
The home’s roof had reached the end of its lifespan, with aging materials sitting over original skip-sheathing decking that was no longer adequate for a modern roofing system. The homeowner needed a complete, code-compliant re-roof that would pass City of San Mateo inspection and provide long-term protection.
Our Solution
Simmitri pulled the required permit, performed a full tear-off, and prepared the existing skip-sheathing deck for a proper modern installation. GAF Tiger Paw synthetic underlayment was laid across the entire roof surface, followed by new GAF asphalt shingles in a charcoal grey tone with a clean ridge cap finish. The project passed its in-progress inspection (Case #BD-2025-300638) and was completed to full city code compliance.

FAQ
Does Simmitri pull permits for roof replacements in San Mateo?
Yes. Simmitri manages the entire permitting process for you. For this San Mateo project, we secured City of San Mateo Case #BD-2025-300638 and ensured the installation passed its Roof In-Progress inspection, confirming full code compliance from start to finish.
What roofing materials were used on this San Mateo home?
We installed GAF asphalt shingles in a charcoal grey finish over GAF Tiger Paw synthetic underlayment. This combination provides excellent protection against moisture infiltration, wind uplift, and the varied weather conditions common throughout the Bay Area.
What is skip-sheathing and how does Simmitri handle it during a re-roof?
Skip-sheathing is an older decking style found in many Bay Area homes where boards are spaced apart rather than laid solid. Before installing modern underlayment and shingles, Simmitri prepares the deck surface to ensure a flat, stable base — delivering a finished roof that meets today’s building code standards.
How does Simmitri ensure quality during the roofing process?
Every Simmitri re-roof is permitted and subject to city inspection. On this San Mateo project, our team coordinated a Roof In-Progress inspection so the underlayment and deck work were reviewed before shingles were laid — giving the homeowner full confidence in the quality beneath the surface.
