When you need work done on your roof, make sure that any contractor you hire is a licensed roofing contractor with the California Contractors State License Board, or CSLB. Hiring a licensed contractor provides you with benefits and protections you will not receive if you hire an person or company that is not licensed with the CSLB.

#1 A Licensed Contractor Will Never Ask You for Illegal Payments

In the state of California, all home construction contractors are only allowed to request a down payment up to $1,000 or 10 percent of the total contract before they start working on a job for you.

You should never be asked to pay more than the legal amounts before a contractor starts a job for you. You should never have to pay for supplies until they are sitting on your property or work until it is completed.

#2 A Licensed Contractor Is Responsible for Paying Subcontractors

Many contractors work with subcontractors to get work done. When you hire a licensed CSLB contractor to replace your roof, they are responsible for paying any subcontractors who perform work on your home.

When you hire a non-licensed contractor, and they hire subcontractors, you become responsible for their payment. Working with a licensed contractor protects you from any payment issues with subcontractors.

#3 A Licensed Contractor Carries Insurance

When you hire a contractor licensed by the CSLB, they are needed to carry their own insurance. If a worker were to get injured while working on your roof, their insurance would cover the cost.

Also, a licensed contractor carries insurance should they damage your home. Working with a licensed expert on any home construction project protects your best interests. When you need your roof repaired or replaced, consider working with the team at Econo Roofing.

Why California's licensing system specifically protects homeowners

The California Contractors State License Board (CSLB) runs one of the most rigorous contractor licensing programs in the U.S. Licensed C-39 Roofing Contractors must show four years of journey-level know-how. They must pass two exams. a trade exam on roofing systems plus a general business and law exam. They must carry workers’ comp and a $25,000 surety bond.

Hiring a licensed roofer in California is more than paperwork. It means hiring someone whose business is contractually required to follow specific construction practices. There’s state-backed financial recourse if things go wrong. An unlicensed roofer can’t offer either. The CSLB and your insurance both rely on the license number.

Insurance and warranty implications of unlicensed work

Most homeowners insurance policies have specific exclusions for damage caused by unlicensed contractors. If an unlicensed roofer causes a leak that damages your interior — or worse, falls and gets injured on your property — your insurance is likely to deny coverage. Workers’ comp falls back on you, the homeowner.

Maker warranties on roofing materials (Owens Corning, GAF, CertainTeed) usually require install by a certified contractor program member. When unlicensed contractors install premium materials, the maker warranty often becomes void. meaning a defective shingle that should have been replaced under warranty becomes the homeowner's expense.

How to verify a California roofing license

The CSLB provides a free online license lookup at cslb.ca.gov. Search by license number, business name, or owner name. The lookup shows current license status (active, suspended, expired, revoked), the classifications held, the bond status, workers' comp status, and any complaint history. Always verify before signing any contract — license numbers can be borrowed or fabricated.

For Econo Roofing, our California Contractor License is #749551, classification C-39 Roofing, set 1996, now active and in good standing with $1M general liability and current workers' comp.

FAQ

Common questions on this topic

Why should I hire a licensed roofer?

Hire a licensed roofer because California requires C-39 licensing for any roofing work over $500. Licensed roofers carry workers comp, liability insurance, and a $25,000 surety bond. Unlicensed work voids your homeowners insurance and manufacturer warranties. Licensed roofers face state-backed accountability through the CSLB.

How do I verify a roofer is licensed in California?

Verify any roofer at CSLB.ca.gov by entering their license number or business name. The CSLB site shows license status, classification (look for C-39 Roofing), bond status, workers comp, and complaint history. Econo Roofing holds CA license #749551 — active and clean since 1996.

What happens if I hire an unlicensed roofer?

Hiring an unlicensed roofer voids your homeowners insurance for any related damage, voids manufacturer warranties on the materials installed, and leaves you liable for worker injuries on your property. The CSLB can also fine homeowners who knowingly hire unlicensed contractors. Always check the license at CSLB.ca.gov.

Why This Matters

Behind every article: 30+ years of Central Valley roofing.

Every article on this blog is written or reviewed by someone who has actually installed, repaired, or inspected the specific roof types and scenarios discussed. That distinction matters. Most roofing content online is written by content marketers who have never set foot on a roof. The advice may sound right, but it misses the practical realities — how shingles age in 110°F Central Valley summers, how tile underlayment fails at year 25-30, how flashing wear compounds over winter Pacific storms, how insurance adjusters evaluate damage claims in Stanislaus County. Field experience changes the answer.

Mario Espindola founded Econo Roofing in 1996 in Delhi, California. Three decades later, our team has installed, repaired, and inspected thousands of Central Valley roofs. We’ve catalogued the failure patterns specific to this region: cracked pipe boots from year 8-10 UV exposure, lifted ridge caps after winter wind events, valley flashing wear at year 15, tile underlayment hitting its 25-30 year service window on 1990s Mediterranean homes. Each of these has a known cause, a known fix, and a predictable cost — but only when diagnosed by someone who has seen it hundreds of times.

The credentials matter for accountability. Econo Roofing is the only Owens Corning Platinum Preferred contractor in Stanislaus County and Merced County — a designation 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. That means we can register manufacturer-backed warranties — OC Platinum Protection (lifetime, non-prorated), GAF Golden Pledge (50-year material plus 25-year workmanship), and CertainTeed 5-Star Protection — that simply aren’t available through uncertified roofers. Each manufacturer audits our installs to maintain our certification, which keeps us honest on every project.

If you’re reading this article because you have a real roofing question or concern, the next step is 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. Schedule at (209) 668-6222. License #749551, verifiable at CSLB.ca.gov. Family-owned and operated since 1996, with three regional offices in Delhi, Ripon, and Turlock serving 52 cities across the Central Valley.

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.
