Residential Roof Tear-Off, Shingle Install & Dry Rot Repair

Homeowners in Santa Rosa, CA, face a mix of intense sun and heavy seasonal rains that rapidly exploit vulnerabilities in aging roofing systems. Upstate Roofing recently executed a complete residential roof tear-off, addressing extensive underlying moisture damage before installing a high-performance composition asphalt shingle system. Operating under strict Cal/OSHA safety regulations, our fully licensed and insured team prioritized structural integrity, rigorous job site cleanup, and long-term weatherproofing.

The tear-off phase revealed severe structural vulnerabilities hidden beneath the original shingles. Chronic moisture intrusion, particularly along the roof valleys, eaves, and around the brick chimney, had caused extensive dry rot. The existing wood decking and fascia were significantly deteriorated, leaving the roof incapable of safely supporting a new, heavy-duty shingle system. Furthermore, navigating the steep roof pitches while safely extracting large volumes of rotted wood and abrasive asphalt debris required strict fall-protection measures and controlled material handling to protect the surrounding residential property.

Worker safety and structural restoration drove our operational approach. Utilizing full-body safety harnesses and anchored lifelines, our technicians stripped the roof down to the bare joists in the compromised areas. We executed extensive dry rot repairs, custom-cutting and installing 32 sheets of fresh CDX plywood and new fascia boards to completely restore the roof's framing and match the existing construction.

With a solid deck established, we installed the 2" x 3" metal drip edges and rolled out a high-quality synthetic underlayment, sealing the critical valleys with heavy-duty leak barriers. We applied starter strip shingles along the roof perimeters to guarantee maximum wind resistance and shingle adhesion. Our crew then precisely installed the new composition asphalt shingles, integrating custom step flashing around the brick chimney and installing new roof vents for optimal attic airflow. Throughout the process, we maintained continuous material pickup, ensuring debris was immediately loaded and hauled away.

To deliver a permanent, watertight, and code-compliant roofing system, our team executed the following comprehensive residential services:

Roof Tear-Off & Disposal: Removed one layer of the existing roofing system down to the roof deck, with all debris safely loaded, hauled, and legally disposed of at an approved facility.
Woodwork (Dry Rot Repair): Removed and replaced deteriorated wood decking and fascia, installing 32 sheets of CDX plywood to provide a solid, code-compliant substrate.
Roof Deck Protection & Drip Edge: Installed new 2” x 3” metal drip edges along all perimeters and rolled out premium synthetic underlayment to serve as a high-quality protective moisture barrier.
Flashing & Vent Components: Replaced all roof vents and installed step flashing around penetrations and the masonry chimney to ensure a watertight seal.
Shingle System Installation: Applied manufacturer-approved starter strips along all eaves and rakes, followed by the installation of new composition asphalt shingles in accordance with local building codes.
Ridge Cap Completion: Finished all roof ridges with new ridge cap shingles for an elevated appearance and additional defense against wind and water intrusion.
Final Jobsite Cleanup & Material Pickup: Performed daily cleanings and a final magnetic sweep, properly hauling away all roofing debris, nails, and job-related materials.

The Santa Rosa residence is now protected by a flawless, multi-dimensional composition asphalt roofing system. The extensive dry rot has been entirely eradicated, securing the home's structural foundation against future moisture intrusion. The newly flashed chimney, properly ventilated decking, and capped ridges provide superior defense against high winds and driving rain. Adhering to our strict final jobsite cleanup protocols, Upstate Roofing completed a thorough magnetic sweep and hauled away all garbage, leaving the homeowner with a high-performance roof and a pristine, hazard-free property.
