About This Service
Reviewed by Mario Espindola, Founder & GAF Master Elite Installer · Updated
Commercial roofs in Brentwood — offices, retail, warehouses, and farm buildings — face the same harsh weather as homes. They add a twist: flat or low-slope decks where drainage has to be planned, not guessed.
For Brentwood commercial properties we install TPO single-ply membrane, standing-seam metal, and elastomeric coatings. Active leak? Our Brentwood emergency roof team responds same-day.
We plan commercial roof work to keep your doors open. Early starts, weekend windows, and phased install on big buildings — whatever your week needs.

Systems & Makers
Each manufacturer has its own membrane mix, warranty tiers, and detail kits. We match the system to how the building is used. No single brand fits every job. We pick what fits yours.
Insulation matters as much as membrane on commercial roofs. Standard practice for Brentwood re-roofs is rigid foam insulation (polyiso) insulation board to meet Title 24 R-value rules, with mechanically-attached or fully-adhered installs depending on building height and wind exposure. EPS (expanded polystyrene) and XPS (extruded polystyrene) are alternative insulation options for specific use cases such as below-membrane or edge applications.
On commercial re-roofs covering over 50% of the deck, we draw up engineered plans. The California Building Code requires them. We file them with the city as part of every permit.
In-Depth Guide
Commercial roofs protect millions of dollars in equipment, inventory, and operations. The right system handles foot traffic, HVAC penetrations, and ponding water that residential roofs never see. For Brentwood homeowners, that calculus matters even more. Central Valley weather is hard on roofs. Summers hit 105°F+. UV exposure is intense. Agricultural dust adds wear. Together, these shorten the life of any roof material. Add winter tule fog and the occasional Pacific storm, and you have one of California’s most demanding roofing climates.
Econo Roofing has worked on Brentwood commercial roofing projects since 1996. Over three decades, our crews have catalogued the failure patterns specific to Brentwood housing stock. The most common issues we see include seam failures on aging single-ply membranes, ponding water around drains, blistered modified bitumen, damaged flashing around HVAC mounts, and granule loss on bituminous surfaces. Each of these has a known cause and a known fix — but only when diagnosed correctly. A repair that addresses the symptom but not the root cause will fail again within months.
Pricing for commercial roofing in Brentwood runs $8-$15 per square foot for typical projects. We’re OC Platinum Preferred AND GAF Master Elite. We’re the only contractor in Stanislaus and Merced County with both credentials. That lets us offer manufacturer-backed warranties most local roofers can’t match. Owens Corning Platinum Protection covers up to 50 years, non-prorated, including workmanship. GAF Golden Pledge offers 50-year materials plus 25-year labor coverage. Both warranties are reserved for top-tier certified contractors.
The right approach to commercial roofing starts with diagnosis. Wrong diagnosis leads to wrong work, wasted money, and shortened roof life. Our Brentwood commercial roofing approach focuses on system selection that matches your building load, traffic, and warranty needs. We document every job with photos, measurements, and written reports. License #749551, in business since 1996, with verifiable reviews on Google, BBB, and GuildQuality.
What to expect
Every commercial roofing project we do in Brentwood follows the same proven process. We start with a free on-site inspection. Our certified inspector walks the entire roof, checks all flashing, vents, valleys, and pipe boots, and inspects the attic for moisture and ventilation issues. We document the inspection with photos and deliver a written report within 24 hours. No pressure, no hard sell — if your roof is healthy, we say so in writing.
Once you approve the project scope, we schedule the work. Brentwood permits go through the local building department; we pull every permit, schedule every required inspection, and handle all paperwork. Homeowners never deal with the permit office directly. Most commercial roofing projects in Brentwood take one to three days depending on roof size and complexity. We monitor weather forecasts closely and reschedule if rain is expected. We protect landscaping with tarps and clean up debris daily.
Materials matter. We install only manufacturer-certified products from Owens Corning, GAF, CertainTeed, and other top-tier brands. As OC Platinum Preferred contractors, we install Owens Corning Duration shingles and Total Protection Roofing System components. As GAF Master Elite contractors, we install Timberline HDZ and the full Weather Stopper system. As CertainTeed Select ShingleMaster contractors, we install Landmark architectural shingles and the 5-Star Protection system.
After install, we register every warranty with the manufacturer within 30 days. We send you copies of the warranty paperwork, photos of the completed work, and a written workmanship warranty from Econo Roofing. Mario Espindola personally reviews every project’s scope and final inspection.

Materials & methods
The materials we install on Brentwood commercial roofing projects are not the cheapest options on the market — and that’s by design. We’re OC Platinum Preferred contractors. That means we install Owens Corning Duration shingles plus the full Total Protection Roofing System. Your roof qualifies for the Platinum Protection Limited Warranty. We’re GAF Master Elite contractors. That means we install Timberline HDZ shingles with the full Weather Stopper system. The result is a Golden Pledge warranty on your roof. As CertainTeed Select ShingleMaster contractors, we install Landmark architectural shingles and the 5-Star Protection system. Each of these top-tier warranties is unavailable through uncertified contractors.
Our methods reflect 30+ years of Brentwood field experience. Every commercial roofing project starts with attic ventilation assessment because the attic environment shortens or extends roof life by 20-30%. Inadequate ridge or soffit venting cooks shingles from the underside; we measure airflow and add ventilation as needed. We install ice and water shield in valleys and at every penetration regardless of climate zone. We use synthetic underlayment rated for high heat. We replace deck damage rather than overlay. We seal every fastener with manufacturer-approved sealants. None of this is mandatory by code, but all of it extends roof life and protects your warranty.
The crew matters as much as the materials. Our Brentwood commercial roofing crews are W-2 employees of Econo Roofing — not subcontractors. Each crew member completes annual GAF Master Elite training and Owens Corning installation certification. Mario Espindola personally reviews every project scope before work begins and inspects the finished roof before the crew leaves the site. We carry $1 million general liability and full workers comp insurance. License #749551, verifiable at CSLB.ca.gov. Family-owned and operated since 1996. Same family, same standards on every Brentwood job.
