Fast, code-compliant commercial and industrial roofing for San Jose businesses — TPO, EPDM, PVC, and modified-bitumen flat roofs, 24/7 emergency leak response, and preventative maintenance contracts that protect your building and your uptime.
Commercial roofing covers the low-slope and flat roof systems on offices, warehouses, retail, and industrial buildings — where drainage, seam quality, and membrane choice decide whether a roof lasts 25 years or leaks in five. We install, restore, and repair TPO, EPDM, PVC, and modified-bitumen roofs across San Jose, and when a leak opens over your inventory we respond 24/7. For pitched or steep-slope buildings, see our roof replacement and metal roofing services.
24/7 emergency response — same-day leak containment and tarping so water never reaches equipment, stock, or tenants.
Heat-welded TPO & PVC systems — factory-spec welded seams and tapered insulation that eliminate ponding water.
Title 24 cool-roof compliance — reflective membranes that meet California code and cut building cooling load 10–30%.
Maintenance contracts — scheduled inspections and repairs that extend roof life and protect the warranty.
Yes — we provide 24/7 emergency commercial and industrial roof repair across San Jose and the South Bay, with same-day response for active leaks. A failed seam or storm-opened leak over a server room, production line, or warehouse stock can cost far more than the roof itself. Our crew contains the leak immediately with tarping and water mitigation, then delivers a written repair or restoration scope with photos and pricing — not a verbal guess.
Same-day response for membrane failures, punctures, blistered seams, flashing leaks, and storm damage on flat and low-slope commercial roofs. We stop the water first, then fix the root cause.
Because we're a local San Jose contractor, emergency calls get a crew on the roof fast — often within hours — followed by a photo-documented scope so building owners and property managers can approve repairs with confidence.
Every commercial roof starts with a rooftop assessment so we recommend the most durable, cost-effective system for your building, traffic, and drainage — not a one-size-fits-all membrane.
Heat-welded, reflective single-ply — the best-value system for most San Jose commercial buildings. 20–30 year lifespan and Title 24 cool-roof compliant.
Multi-ply torch-down for high-traffic and ponding-prone roofs — rugged, redundant waterproofing that stands up to foot traffic and rooftop equipment.
Reflective silicone and acrylic coating systems that restore an aging flat roof and extend its life at a fraction of tear-off cost — ideal for tight maintenance budgets.
Chemical-resistant PVC for restaurants and buildings with grease exhaust, and durable EPDM for large low-slope roofs — welded or seam-taped for a watertight envelope.
A commercial roof protects everything under it — inventory, equipment, tenants, and uptime. Here's what a properly specified system delivers.
Tapered insulation, crickets, and welded seams move water off the roof instead of into it — the #1 cause of premature flat-roof failure.
Reflective cool-roof membranes meet California Title 24 and cut rooftop heat gain, lowering HVAC load across San Jose's warm season.
Manufacturer system warranties up to 30 years plus our workmanship warranty — registered and protected with a maintenance plan.
From first call to warranty registration, a clear process keeps your project on schedule and your building dry.
We inspect the membrane, seams, drainage, insulation, and penetrations, then document conditions with photos and moisture readings.
You get an itemized proposal with the recommended system, drainage corrections, and a phased schedule that keeps operations running.
Our crews install to manufacturer spec, pass inspection, and register your system warranty — with maintenance options to protect it long-term.
Local, licensed, and commercial-first — with 24/7 emergency response and the reviews to back it up across the South Bay.
A full commercial flat-roof replacement — old, failing surface removed and rebuilt with a clean, watertight membrane system.
Yes — we provide 24/7 emergency commercial roofing service across San Jose and the South Bay. When a membrane fails or a storm opens a leak over inventory or equipment, our crew responds the same day, starting with emergency tarping and water mitigation to stop interior damage, then delivers a written repair or restoration scope with photos.
For most San Jose commercial and industrial buildings, TPO is the best-value flat-roof system: heat-welded seams create a monolithic watertight membrane, the reflective white surface cuts cooling load and helps meet Title 24, and it lasts 20–30 years. Modified bitumen (torch-down) suits high-traffic or ponding-prone roofs, and roof coatings can restore an existing roof at a fraction of tear-off cost.
Commercial flat-roof replacement in San Jose typically runs $7–$14 per square foot installed, depending on the system (TPO, modified bitumen, or PVC), the amount of tapered insulation needed to correct drainage, and rooftop penetrations like HVAC curbs and skylights. We provide a written, itemized proposal after a rooftop assessment — no ballpark-only quotes.
Yes. We schedule commercial and industrial re-roofs in phases so your business keeps operating — sequencing sections, protecting rooftop equipment, and keeping the interior dry throughout. For HOAs and property managers we provide inspection reports, budget planning, and phased scheduling that minimizes tenant disruption.
Yes — preventative maintenance contracts include scheduled inspections, seam and flashing checks, drain and scupper clearing, and minor repairs that extend the life of a commercial roof and protect its warranty. Pairing maintenance with a documented roof inspection catches small problems before they become leaks.
Yes — Lifetime Roofing & Renovation is fully licensed (CA License #1090028, C-39 Roofing) and insured, and we're an Owens Corning Platinum Preferred Contractor. We also serve nearby markets, including commercial roofing in Sunnyvale and across Santa Clara County.
From a 24/7 emergency leak to a full flat-roof replacement or a maintenance contract, get an honest rooftop assessment from San Jose's commercial roofing team — same-day emergency response available.
A reflective "cool" membrane bounces sunlight instead of absorbing it, which lowers rooftop and attic-plenum temperatures, reduces HVAC load through the summer, and slows heat-related aging of the membrane. For flat and low-slope commercial roofs in San Jose, Santa Clara, and Sunnyvale, that means both code compliance and lower cooling bills over the life of the roof.
Not every project is required to hit the prescriptive cool-roof path — some qualify for exceptions or a performance-based alternative. We confirm the requirement for your building during the free commercial roof inspection and document compliance for your permit.
