Who We Are

Restco Roofing Inc. is a licensed commercial and industrial roofing contractor headquartered in Lake Forest, California. We specialize in high-performance roof restoration, replacement, repair, and maintenance for commercial and industrial facilities across all of Southern California.

Our team brings over 100 years of combined commercial roofing experience to every project. We are factory-authorized by GE Enduris as a certified silicone applicator, factory-trained by GAF, and maintain active OSHA safety certifications for all installation crews.

We hold an active California C-39 Roofing Contractor License (#1076149) and are qualified to deliver manufacturer warranties of up to 30 years on select systems. Every project we complete is backed by our Proactive Roof Inspection Program, providing annual inspections for the full term of the manufacturer's warranty.

Based in Lake Forest, CA, we serve commercial properties throughout Los Angeles, Orange, San Diego, Riverside, San Bernardino, Ventura, and Imperial counties.

Serving All of Southern California

We serve commercial and industrial facilities across 7 counties — from Ventura to Imperial, and from the coast to the Inland Empire.

Our Commitment to Commercial Roofing

We believe commercial roof decisions should be based on clear information, honest recommendations, and proven systems — not high-pressure tactics.

Proactive Inspection Program

Every restoration and replacement project includes annual inspections for the full term of the manufacturer's warranty — with a full-color photo report after every visit. This keeps your warranty current and catches developing issues before they become costly failures.

Restoration-First Approach

We start every engagement with an honest assessment of whether restoration is viable. When restoration is an option, it saves you up to 70% vs. full replacement and qualifies as a 100% maintenance expense for tax purposes. We'll always recommend the right solution — not the most expensive one.

Factory Certification & Safety

Our crews are factory-trained by the manufacturers whose products we install. OSHA safety certification is maintained for all installation teams. You get the confidence of manufacturer-backed workmanship — not just a contractor warranty.
