Commercial roofs that earn their warranty.

Commercial systems are flat or low-slope (usually 1:12 to 4:12 pitch), use single-ply membranes (TPO, EPDM, modified bitumen) instead of shingles, and require unique waterproofing strategy at penetrations (HVAC curbs, drains, scuppers). The crew, materials, and code path are all different — not "residential at scale."

60-mil TPO installed in California's Central Valley usually runs $7–$12 per square foot, depending on substrate condition, insulation R-value, edge metal scope, and HVAC leak count. A 20,000 sq ft warehouse typically lands $140K–$240K turnkey. We quote flat-rate after on-site inspection.

Yes. Most commercial re-roofs we do are phased — we complete sections at a time so business operations continue. We coordinate around your peak hours, isolate dust during tear-off, and protect interior finishes. Zero forced closures on every commercial re-roof we've completed since 1996.

TPO membranes usually carry 15–30 year manufacturer warranties (Carlisle SynTec, Firestone, GAF Everguard). Workmanship warranties from Econo Roofing run 5–10 years depending on system. We provide a single warranty document covering both — and we register the manufacturer warranty in your name at close-out.

60-mil TPO: 20–30 years with proper maintenance. EPDM (rubber): 25–30 years. Modified bitumen: 15–20 years. Silicone coating restoration: 10–15 more years on a sound substrate. The maintenance program matters more than the membrane brand for hitting the top of those ranges.

Yes. We document storm damage with drone imagery, meet adjusters on-site, provide detailed scope reports, and negotiate scope with the insurer when needed. Most claims close within 4–6 weeks of damage event. We've worked with most major California commercial carriers.

Over a 25-year horizon, warranty tier matters more. An NDL (No Dollar Limit) warranty costs 4–7% more upfront but eliminates the financial cliff on a major leak event. Membrane thickness (60-mil vs 45-mil) is the second-biggest lever. Price per sq ft alone hides the real total-cost-of-ownership.

Core-sample first. If insulation moisture content is under 5% by weight and the substrate is structurally sound, a recover saves 30–40% on initial cost. Above 5% moisture, a recover traps water against new membrane and you fail within 5 years — tear-off is the only honest answer. We always core-sample before recommending either path.

Almost always, yes. A cool-rated white TPO membrane cuts HVAC cooling loads 15–25% vs. dark membranes during 100°F+ summers. California Title 24 mandates cool roofs on most commercial replacements anyway — so the question is usually "which cool-rated system" not "cool or not."
