At Northbay Roofing Co, we bring over two decades of experience to every commercial roofing project in Novato and Marin County. Our team understands the unique demands of flat and low-slope roofing systems, from built-up roofs (BUR) and modified bitumen to single-ply TPO, PVC, and EPDM membranes. We also specialize in standing seam metal roofs for commercial buildings that want a durable, energy-efficient solution with a 40-year lifespan. What Does Commercial Roof Replacement Cost in Novato? Commercial roof replacement in Novato typically ranges from $8.50 to $18.00 per square foot, depending on material, roof complexity, and accessibility. A 2,000-square-foot flat TPO roof averages $17,000 to $24,000 installed. Metal roofs run $12 to $22 per square foot. We provide detailed, line-item quotes so you know exactly where your investment goes. Our Commercial Roofing Process We follow a proven six-step process for every commercial project. Step one: thorough roof inspection and moisture survey. Step two: structural assessment and substrate preparation. Step three: removing old roofing and repairing decking. Step four: installing vapor barrier and insulation layers. Step five: membrane or metal panel installation with thermal-welded seams or mechanically fastened clips. Step six: final quality inspection and warranty paperwork. Material Options for Your Novato Business TPO roofing is our most popular choice for Novato commercial clients. It reflects UV rays, lowers cooling costs by up to 25%, and resists punctures. PVC offers superior chemical resistance for restaurants or industrial spaces. EPDM rubber provides a budget-friendly option with proven 30-year durability. For a premium upgrade, standing seam metal roofs handle Marin County's fire season with a Class A fire rating and 140 mph wind resistance. Timeline and Project Duration Most commercial roof replacements take 5 to 10 working days, depending on size and weather. A 3,000-square-foot TPO roof on a Novato office building typically wraps up in 7 days. We work around your schedule to minimize downtime. Weekend and evening work is available for retail or restaurant properties. Warranty and Ongoing Maintenance We back every commercial roof with a minimum 10-year workmanship warranty and manufacturer warranties up to 30 years. Our annual maintenance program includes fall and spring inspections, debris removal, and minor repairs to extend your roof's life by 5 to 10 years. Why Northbay Roofing Co for Your Commercial Roof?

How do I know if my commercial roof needs replacement? Look for ponding water that stays 48 hours after rain, blisters or bubbles in the membrane, cracked flashings, or interior water stains. A professional moisture survey can detect hidden leaks before they cause structural damage. Do you offer financing for commercial roof replacement? Yes. We partner with GoodLeap and Hearth to offer 0% interest options for qualified businesses. Ask your estimator for details during your free consultation. What is the best roofing material for a Novato commercial building? For most Novato businesses, TPO offers the best balance of cost, energy savings, and durability. If your building has heavy equipment on the roof, consider PVC or EPDM for added puncture resistance.
