Roof restoration typically costs $3-6 per square foot, while full replacement runs $8-14 per square foot in Southern California. For a typical 10,000 square foot commercial building, you’re looking at $30,000-60,000 for restoration versus $80,000-140,000 for replacement.
The savings go beyond the upfront cost. Restoration projects usually take days rather than weeks, so you avoid the business disruption costs that come with full replacement. No lost productivity, no temporary relocations, no noise complaints from tenants.
Most restoration projects also qualify for similar warranty coverage as replacement systems, so you’re not sacrificing protection for savings. With proper maintenance, a restored roof can give you 10-15 more years of service—often enough time to plan and budget for an eventual replacement on your terms rather than during an emergency.
