San Diego homeowners searching for the best roofing companies in San Diego find no shortage of options. The challenge is knowing which contractors carry the local depth, verified credentials, and consistent track record to back up their claims. This guide examines well-known San Diego roofing companies — who they are, what they specialize in, and what sets Dils Roofing & Solar apart from the field.

Every company mentioned here holds a valid license and maintains a verifiable local presence. This is not a ranking designed to tear anyone down. It is a practical comparison to help you make an informed decision for your home.

What Makes a Great San Diego Roofing Company?

Before comparing specific companies, know what to measure. The best roofing companies in San Diego share a few defining traits: deep local roots, a valid CSLB C-39 license, manufacturer certifications that signal quality installation, strong and consistent reviews across independent platforms, and community recognition that reflects real homeowner experience.

San Diego’s specific conditions also matter — coastal salt air, intense UV exposure, Santa Ana wind events, and regional building code requirements all separate a locally seasoned contractor from one still learning the market. A company that has roofed in San Diego for decades brings knowledge that newer or out-of-area operators simply have not had time to build.

Below is a side-by-side look at three well-known roofing companies operating in San Diego County today. We drew this information from publicly verifiable sources including the CSLB, BBB, and each company’s website.

A Closer Look at Each Company

Dils Roofing & Solar — San Diego’s Longest-Running Family Roofer

Dils Roofing & Solar has operated continuously in San Diego since 1982 — making it one of the longest-established roofing companies in the county. Four generations of family ownership mean continuity of leadership and a genuine stake in the community that a corporate chain cannot replicate. When you call Dils, you reach a company that has built its reputation roof by roof over more than four decades.

Dils holds CSLB License #639961 and earned CertainTeed Select ShingleMaster certification through demonstrated installation quality. Their services cover the full range of residential roofing — repair, replacement, tile, shingle, and flat roofs — along with solar installation and gutters.

Tenure and specialization set Dils apart most clearly from competitors. Roofing has been the company’s core business since day one. That single-minded focus, combined with over 40 years of San Diego-specific experience, gives Dils crews a depth of knowledge around local materials, microclimates, and permit requirements that newer or multi-service companies are still working to develop.

Semper Solaris — Home Services Company

Kelly Shawhan and John Almond founded Semper Solaris in San Diego in 2012 as a residential solar installation company. The veteran-owned business grew significantly over the following decade, adding roofing, HVAC, and battery storage to its service lineup. Semper Solaris holds CSLB license #978152, carries BBB accreditation, and earned Owens Corning Platinum Preferred Contractor status.

Solar and home energy remain the company’s primary focus — roofing sits as one service within a broader portfolio.

San Diego Roofing Inc. — Roofing Contractor

San Diego Roofing Inc. holds BBB accreditation dating to 2011 and focuses on both residential and commercial roofing across a range of materials. The company operates as a licensed, bonded, and insured contractor with a verifiable local presence in San Diego County.

Homeowners looking for a roofing-focused contractor with regional history will find San Diego Roofing Inc. a legitimate option in the market. As with any contractor, check their current license status at cslb.ca.gov and read independent review profiles before signing anything.

Why Homeowners Choose Dils Roofing

Dils Roofing reviews consistently highlight the same themes: responsive communication, no-pressure estimates, crews that show up on time, and work that holds up over time. That kind of track record does not appear in a year or two. It builds over 40-plus years of showing up for San Diego families.
