Econo Roofing is an Owens Corning Platinum Preferred contractor — the highest title OC awards. It means your roof is installed to OC's exact standards and backed by their strongest warranty. Not ours. Theirs.

The Designation

What Owens Corning Platinum Preferred means for you.

You cannot buy this. Owens Corning Platinum Preferred is invite-only — the top 1% of roofers in the U.S. When you hire an OC Platinum Preferred contractor, you get something most homeowners never can: OC stands behind both the product and the install. That means access to warranties other roofers cannot offer.

Your roof. Their guarantee.

When Econo Roofing installs your roof, OC backs it with the Platinum Protection Limited Warranty. That means lifetime coverage on both materials and workmanship. OC is not just selling shingles. They are vouching for the crew that put them on.

That is the difference. Not just a roofer — a contractor with OC standing behind every install. For homeowners in California, this is the top standard.

The Difference

Same shingles. Different warranty.

Any licensed contractor can install Owens Corning shingles. But the warranty you get depends on the contractor's tier. Here is what each level unlocks.

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 serving the Central Valley. Same family ownership, same crew standards, same focus on getting the install right the first time.

Our credentials aren’t marketing claims. They’re earned through years of training, install audits, and customer tracking. Each maker keeps our cert only if our quality stays above their bar. We’ve held Owens Corning Platinum Preferred since 2008. GAF Master Elite for over a decade. CertainTeed Select ShingleMaster without a gap. The audits keep us honest — the makers track every job we file. Econo Roofing is the only contractor in Merced and Madera County to hold all four top-tier certs at the same time.

We carry $1 million general liability and full workers comp. We’re bonded ($25,000 CSLB bond). License #749551 — look it up at CSLB.ca.gov. The same family that started in 1996 still runs the company. Mario reviews every job scope before work starts and checks the finished roof before the crew leaves. Every customer gets warranty paperwork, job photos, and a written workmanship warranty. No subs. No surprises.

We focus on 15 cities in Merced and Madera counties for homes. For commercial work, we serve the wider Central Valley — backed by all four top certs, including OC Platinum Preferred. We send the closest crew from our Delhi office. Free written estimates across our full service area. Call (209) 668-6222 and you reach the same family that’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, we’ve grown to a 20-person team serving the Central Valley. 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 locally based, quad-certified contractor in Merced and Madera County. 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.
