At Henris Roofing, we’ve guided property owners through this exact situation for over 80 years. A roof replacement isn’t just about laying new shingles. It’s about protecting everything beneath that roof, preserving property value, and giving you decades of confidence during storm season. We provide free estimates with no conditions attached, so you can understand the true condition of your roof before committing to any work.
Our Roof Replacement Process
We approach every replacement methodically, because shortcuts create the very problems we’re trying to solve. Our crews begin with a thorough inspection of the entire roof system, including the decking, flashing, ventilation, and any signs of moisture intrusion. Only after we fully understand the condition of your existing structure do we recommend a replacement scope tailored to your building.
Once the plan is approved, our replacement follows a consistent, disciplined sequence designed to protect your home and deliver lasting results.
- Property protection: We cover landscaping, siding, and outdoor features before any tear-off begins.
- Complete tear-off: We remove old shingles down to the decking so we can inspect and repair the wood underneath.
- Decking and repairs: Any rotted or weakened decking is replaced to create a solid, reliable foundation.
- Underlayment and flashing: We install moisture barriers and reseal all valleys, chimneys, and vents.
- Shingle installation and cleanup: New materials go on with precision, and we thoroughly clean the site before we leave.
We respect your property and are mindful to clean up after ourselves, running magnetic sweeps across your yard and driveway to collect stray nails and debris. Our goal is to leave your property looking better than we found it, with a roof that performs for decades.
Materials and Technical Standards
The materials we install directly affect how long your new roof lasts and how well it withstands wind, hail, and temperature swings. As a GAF Master Elite contractor and ShingleMaster Pro certified company, Henris Roofing holds credentials that fewer than a small percentage of roofers nationwide earn. These certifications allow us to offer enhanced manufacturer warranties and reflect a commitment to ongoing training and proven workmanship.
We work with architectural asphalt shingles rated for high wind resistance, along with specialized underlayments, ice-and-water shields, and ridge ventilation systems that regulate attic temperature and moisture. Proper ventilation is often overlooked, yet it’s critical: without balanced intake and exhaust airflow, heat and humidity can shorten shingle life and drive up energy costs. We calculate the correct ventilation ratio for each roof so your new system breathes the way it should.
For clients interested in sustainability, we’re proud to be Energy Solar Certified and a Timberline Solar Roofing Contractor. This means we can integrate solar-generating shingles directly into your new roof, giving you clean energy production without the bulky look of traditional panels. Doing our part in being environmentally friendly with best practices and materials is a value we build into every project.
Residential and Commercial Applications
Our replacement work spans a wide range of properties across Petaluma, CA and surrounding areas. On the residential side, we handle everything from modest single-family homes to large multi-gable estates with complex rooflines that demand careful flashing and valley detailing. For commercial clients, we replace flat and low-slope systems on retail centers, warehouses, apartment complexes, and office buildings, matching each material choice to the demands of the structure.
Because storm damage rarely waits for convenient timing, we also offer 24/7 emergency service. If a fallen tree or severe wind event exposes your interior, we can secure the roof quickly and then plan a full, permanent replacement. Serving homeowners and businesses throughout Petaluma, Penngrove, Novato, Rohnert Park, Cotati, Santa Rosa, & Sonoma, CA, we bring the same professional, reliable, efficient, and established approach to every job.
