** The roofing market in Ontario, California, is competitive and robust, driven by the region's mix of older residential properties, extensive commercial and industrial developments (including the presence of Ontario International Airport and large warehouses), and exposure to seasonal sun and occasional wind events. The average quality of contractors is high, with reputable companies holding state licenses and key manufacturer certifications (e.g., GAF, Owens Corning). Competition is strong, which generally benefits consumers through competitive pricing and a focus on customer service. Typical pricing for a standard asphalt shingle roof replacement on a single-family home can range from **$8,000 to $15,000+,** heavily dependent on the roof's size, pitch, and material choice. Commercial roofing costs are highly variable based on the system type (TPO, EPDM, Metal) and square footage.

Get answers to common questions about roofing services in Ontario, California.
For a standard asphalt shingle roof on a 2,000 sq. ft. home in Ontario, homeowners can expect costs to range from $8,500 to $15,000, with the final price heavily dependent on material choice, roof complexity, and current material/labor rates. Prices are influenced by California's high cost of living and stringent building codes, which require specific materials and installation methods. Always get 3-4 detailed, written estimates from licensed local contractors for an accurate price for your specific home.
The ideal time is during our extended dry season, typically from late spring through early fall (May to October), to avoid the rare but possible winter rains. However, summer heat can be intense, so reputable contractors will start work early in the morning. Scheduling well in advance for this peak period is crucial, as quality roofers in the Inland Empire are often booked months ahead.
Absolutely. Given our hot, dry summers and intense UV exposure, materials with high solar reflectance and thermal emittance are ideal for energy efficiency. Concrete or clay tiles are excellent, durable choices that handle the heat well, while modern asphalt shingles rated for high temperatures (like those with reflective granules) are a popular, cost-effective option. All materials must meet California's Title 24 energy efficiency standards.
First, verify they hold a valid **California Contractors State License Board (CSLB) license** in the "C-39 Roofing" classification and carry ample insurance. Always check local reviews and ask for references from recent jobs in the Inland Empire. A trustworthy Ontario roofer will provide a detailed written contract, explain local building permit requirements (which they should pull), and offer strong manufacturer warranties on both materials and labor.
Yes, a building permit from the City of Ontario's Building & Safety Department is mandatory for a full roof replacement. This ensures the work complies with the California Building Code (CBC), including critical wind uplift resistance and fire ratings for our wildfire-prone region. Your chosen contractor should handle the permit process, and the work will be inspected to confirm proper underlayment, flashing, and ventilation are installed.
