What we stand for

Three decades of doing it right.

Econo Roofing was founded in 1996 by Mario Espindola in Delhi, California. The original mission was simple: do the work right the first time. Three decades later, that’s still how we operate. We’ve grown from a three-person crew with one truck to a 20-person team. Same family ownership. Same crew standards.

The credentials we hold aren’t marketing claims. They’re earned through years of training, install audits, and customer satisfaction tracking. Each manufacturer keeps our certification only if our quality stays above their thresholds. We’ve held Owens Corning Platinum Preferred status since 2008. We’ve held GAF Master Elite for over a decade. We’ve held CertainTeed Select ShingleMaster continuously. The audits keep us honest. Manufacturers track every job we register, so we can’t cut corners on material grade or install method. Econo Roofing is the only contractor in Merced and Madera County to hold all four top-tier manufacturer credentials at the same time.

We carry $1 million general liability insurance and full workers compensation coverage. We’re bonded ($25,000 CSLB contractor bond). License #749551, verifiable at CSLB.ca.gov. The same family that started the business in 1996 still runs it. Mario reviews every project scope before work begins. He inspects the finished roof before the crew leaves the site. Every customer gets warranty paperwork, job photos, and a written workmanship warranty from Econo Roofing. No subcontractors. No surprises.

For residential roofing, we serve 15 cities across Merced and Madera counties. For commercial roofing, we work throughout the Central Valley. All 4 top manufacturer certifications back every job, including OC Platinum Preferred. We dispatch from our Delhi headquarters for the fastest response. Free written estimates are available across our entire service area. Call (209) 668-6222 to reach the same family that has been roofing the Central Valley for three decades.

A note from Mario

Why this work matters to us.

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

Mario Espindola founded Econo Roofing in 1996. Three decades later, we have a 20-person team serving the Central Valley. The operating principle hasn’t changed: do the work right the first time. We document everything with photos. We stand behind every install with a written workmanship warranty. We register every manufacturer warranty within 30 days of completion. We treat every customer like a neighbor, because in the Central Valley, most of them are.

Our credentials are earned, not bought. Econo Roofing is the only locally based, quad-certified contractor in Merced and Madera County. We hold GAF Master Elite (top 2% of GAF contractors), CertainTeed Select ShingleMaster (top 1% of CertainTeed contractors), and GAF Gold Elite. No other contractor in the region holds all four at once. Each manufacturer audits our installs to keep our certification active. That means we can’t cut corners on material grade or finish quality. The audits keep us honest on every job.

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. Call (209) 668-6222 for free written estimates across the 15 cities we serve in Merced and Madera counties.
