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 the operating principle. We’ve grown from a three-person crew with one truck to a 20-person team across three regional brands — Econo Roofing in Delhi, Nushake Roofing in Ripon, and DeHart Roofing in Turlock. Same family ownership, same crew standards, same focus on getting the install right the first time.

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

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. We’re family-owned and operated — the same family that started the business in 1996 still runs it. Mario personally reviews every project scope before work begins and inspects the finished roof before the crew leaves the site. We send copies of the warranty paperwork, photos of the completed work, and a written workmanship warranty from Econo Roofing to every customer. No subcontractors, no surprises, no unanswered questions.

Our work spans 52 cities across 10 California counties: Stanislaus, Merced, San Joaquin, Tuolumne, Calaveras, Alameda, Contra Costa, Sacramento, Solano, and Fresno. We dispatch the closest available crew from our three offices for fastest response. Free written estimates available across our entire service area. (209) 668-6222 reaches the same family who’s 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 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.
