Our Commercial Roofing Process: Step by Step
Step 1: Free Roof Inspection & Assessment
We start with a thorough inspection of your existing roof. We check for water damage, ponding water, membrane condition, flashing integrity, and insulation moisture. You'll get a detailed report with photos and a clear recommendation — no jargon, just facts.
Step 2: Material Selection & Budgeting
We walk you through the best options for your building. For most San Ramon commercial properties, we recommend TPO (thermoplastic polyolefin) for flat roofs — it's energy-efficient, durable, and cost-effective at $6–$10 per square foot installed. For pitched roofs, we offer standing seam metal roofing at $10–$16 per square foot, with a 40-year lifespan. We also install modified bitumen and EPDM systems. Every quote includes a line-item breakdown so you know exactly where your money goes.
Step 3: Scheduling & Prep
Once you approve the estimate, we schedule the work to minimize disruption to your business. We set up safety barriers, protect landscaping and entrances, and coordinate with your property manager. Most commercial re-roofs take 3–7 days depending on size and complexity.
Step 4: Tear-Off or Overlay?
We recommend a full tear-off for most commercial roofs to avoid adding weight and to let us inspect the deck. For single-ply membranes in good condition, we can overlay in some cases. We'll explain the trade-offs so you can decide.
Step 5: Installation & Quality Checks
Our crew follows manufacturer specifications to the letter. We seal every penetration, install proper flashing at parapets and curbs, and test for leaks. We take photos at each stage for your records.
Step 6: Final Walkthrough & Warranty
After completion, we walk the roof with you or your facility manager. We provide a 10-year workmanship warranty and transferable manufacturer warranties ranging from 15 to 30 years. No callbacks, no surprises.
