Credentials & Proof

The only roofer in Merced and Madera County who holds all four top-tier manufacturer credentials — simultaneously, always.
Specialties
Built for the Central Valley.
Mario’s 41 years on roofs split into four areas of deep field expertise — the work he’s done thousands of times.
Residential roofing
Asphalt shingle, tile, and metal systems for Central Valley homes. Mario has installed thousands of homes since 1996. From 1970s ranch homes in Modesto to new builds in Stockton. Every install registered for full manufacturer warranty within 30 days.
Residential servicesCommercial low-slope
TPO, EPDM, modified bitumen, and elastomeric coatings for warehouse, retail, and ag buildings across the San Joaquin Valley logistics corridor. GAF Gold Elite certified since 2013. One of the few in Stanislaus County qualified for low-slope work.
Commercial servicesStorm damage & insurance
Hail, wind, and atmospheric river damage assessment. Mario has handled hundreds of insurance claims for Central Valley homeowners. He documents damage. He works with adjusters. He rebuilds to code. Drone aerial inspection included on every storm claim.
Storm damage servicesTitle 24 cool roofs
California Title 24 cool-roof code requires reflective surfaces on most reroofs. Mario’s teams know which products meet code. They know which qualify for utility rebates. They know how to spec them for 110°F summers. Critical knowledge for Modesto, Stockton, and Sacramento reroofs.
Read Title 24 guideTile & metal roofing
Concrete tile, clay tile, and standing-seam metal. Mario’s a CertainTeed Select ShingleMaster and knows tile underlayment service windows on Central Valley Mediterranean homes. Critical for 1990s and 2000s tile reroofs.
Tile roofing servicesFree roof inspection
Drone aerial assessment plus interior + exterior walk. Mario or a foreman writes the report personally. Photos, measurements, and a flat-rate written estimate within 24 hours. No obligation, no upsell, no pressure.

Editorial Perspective
Forty-one years on California roofs. Here is what holds up.
I started carrying bundles on the Hendricks Brothers crew in 1985. I was sixteen, and the day-one job was hauling 80-pound bundles of asphalt up a ladder in 105 degrees. Within a month I had taken apart and reassembled a tear-off down to the rafters. That summer is when I learned the difference between a roof that lasts twenty-five years and a roof that fails in eight — and it is almost never the shingle. It is the flashing detail at the chimney, the underlayment selection in the valleys, the ridge ventilation balance, and the slip-sheet on a tear-off over original 1×6 sheathing.
In 1996 I founded Econo Roofing out of my truck. The market in Merced and Madera county had two kinds of roofers — high-volume tear-and-stack outfits that finished a roof in six hours and never came back, and old-timer shops with no manufacturer credentials. I wanted a third option: a Latino-owned crew that would do the manufacturer-spec install, register the warranty correctly the first time, and answer the phone fifteen years later when a homeowner called about a registered claim.
Today we are the only contractor in our two-county footprint that holds all four top manufacturer certifications — OC Platinum Preferred, GAF Master Elite, CertainTeed Select ShingleMaster, and GAF Gold Elite. That is not marketing copy. It is a hard requirement we re-certify every year through annual manufacturer audits, continuing-education hours, and warranty-claim reviews.
Three patterns from four decades that I tell every prospective customer.
First: the Central Valley summer is a roofing fingerprint. We hit 110°F for forty days a year. That destroys budget asphalt three-tab shingles in twelve to fifteen years; a properly-installed architectural shingle with cool-roof granules lasts twenty-five to thirty. The premium pays back inside seven years.
Second: tile is the right answer for more Central Valley homes than people think. The math is unintuitive — tile costs roughly 1.6× asphalt on a one-time install but lasts 50+ years versus 25. Across a homeowner's tenure the per-year cost is lower. The catch is the underlayment: a cheap underlayment under expensive tile is the most common Central Valley roofing mistake we re-do.
Third: ventilation is not optional. Most homes I inspect have ridge-to-eave airflow that is fifty percent of what code requires. That single misfire shortens shingle life by five-to-eight years and bakes the deck. We will not install a new roof without correcting the ventilation balance first.
On insurance work I tell homeowners three things the carrier will not say out loud. One: an adjuster's first scope is a baseline, not a verdict — every line item is negotiable with photographic evidence and matching-shingle documentation. Two: replacement-cost-value versus actual-cash-value is the single most consequential checkbox on your policy, and most homeowners misunderstand the depreciation hold-back. Three: California Insurance Code section 2071 sets a one-year statute on supplements after the first payment. Miss it and the supplement is barred even if the original scope missed the matching valleys.
On contractor selection: the license number is the floor, not the ceiling. Verify it at cslb.ca.gov — then ask three questions the license check does not surface. Ask which manufacturer certifications the contractor holds and request the certification certificate (not just a sticker on the truck). Ask for the contractor's workers-comp coverage certificate addressed to the customer — an uninsured crew is the homeowner's liability if someone falls. Ask how a warranty claim works in year fifteen — the answer should be a name, a phone number, and a written process, not "call us and we'll see."
The articles above are what I write when a Central Valley homeowner asks the same question for the fifteenth time. They are field notes — not generic SEO copy — and every one of them goes through manual fact-check against our two-county install database before it publishes. If you have a question I have not written about, the phone is (209) 668-6222 and you will reach our office in Delhi. Same family, same standards, same number since 1996.
