TPO is the most common choice for Sonora commercial buildings due to its heat reflectivity and low maintenance. For buildings with rooftop equipment or heavy foot traffic, PVC or modified bitumen offers superior puncture resistance. We assess your building and recommend the best fit.
Most commercial roof replacements in Sonora take three to ten business days depending on the roof size, system type, and weather. We work around your business schedule to minimize disruption and can phase the project if needed.

Systems & Makers

Commercial roofing systems for Sonora buildings.

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 Sonora re-roofs is polyisocyanurate (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

Why commercial roofing in Sonora matters.

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 Sonora homeowners, that calculus matters even more. The Central Valley climate puts extreme stress on roofing systems — 105°F+ summers, intense UV exposure, and dust from regional agriculture all 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 Sonora commercial roofing projects since 1996. Over three decades, our crews have catalogued the failure patterns specific to Sonora 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 Sonora runs $8-$15 per square foot for typical projects. As OC Platinum Preferred and GAF Master Elite contractors — the only contractor in Stanislaus County and Merced County to hold both credentials simultaneously — we can offer manufacturer-backed warranties most local roofers cannot 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 Sonora 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

Our Sonora commercial roofing process.

Every commercial roofing project we do in Sonora 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. Sonora 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 Sonora 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. Three decades of Sonora commercial roofing work, three regional offices in Delhi, Ripon, and Turlock, and one phone number for everything: (209) 668-6222.

Materials & methods

How we approach commercial roofing in Sonora.

The materials we install on Sonora commercial roofing projects are not the cheapest options on the market — and that’s by design. As OC Platinum Preferred contractors, we install Owens Corning Duration shingles, Total Protection Roofing System components, and the full line of OC accessories that qualify your roof for the Platinum Protection Limited Warranty. As GAF Master Elite contractors, we install Timberline HDZ shingles, the Weather Stopper roofing system, and qualifying GAF accessories that unlock the Golden Pledge warranty. 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 Sonora 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 Sonora 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 Sonora job.

A note from Mario

Why this work matters to us.

Roofing is more than a transaction. The roof you install on a Central Valley home protects your family for decades. Wrong materials, wrong methods, or wrong crew, and you’re replacing it again in 12 years instead of 30. Right materials, right methods, and a properly trained crew, and your roof outlasts the mortgage. The difference is install detail, manufacturer-grade materials, and the certifications that hold contractors accountable.

Mario Espindola founded Econo Roofing in 1996. Three decades later, the company has grown to a 20-person team across three regional brands — Econo Roofing in Delhi, Nushake Roofing in Ripon, and DeHart Roofing in Turlock — but the operating principle hasn’t changed. Do the work right the first time. Document everything with photos. Stand behind the install with a written workmanship warranty. Register every manufacturer warranty within 30 days of completion. Treat every customer like they’re a neighbor — because in the Central Valley, most of them actually are.

Our credentials are earned, not bought. Econo Roofing is the only OC Platinum Preferred contractor in Stanislaus and Merced County — a tier held by fewer than 1% of US roofing contractors. We’re also GAF Master Elite (top 2% of GAF contractors), CertainTeed Select ShingleMaster (top 1% of CertainTeed contractors), and GAF Gold Elite. No other roofing contractor in the region holds all four credentials simultaneously. Each manufacturer audits our installs to maintain certification, which means we can’t cut corners on material grade, install method, or finish quality. The audits keep us honest on every project.

License #749551, verifiable at CSLB.ca.gov. We carry $1 million general liability insurance, full workers comp coverage, and a $25,000 CSLB contractor bond. Family-owned and operated.
