Flat Roofing Services in San Ramon, CA When your flat roof leaks, you need a San Ramon roofing contractor who understands the unique demands of low-slope systems. At Sanramon Roof Repair, we've been serving this community since 2005. We know the local weather patterns, building codes, and material suppliers. We bring that experience to every flat roof we touch. ### Why Flat Roofs Need Special Care Flat roofs don't shed water like pitched roofs. Standing water, ponding, and UV degradation are constant threats. A tiny puncture can turn into a major water damage event inside your home or business. That's why we use a thorough inspection process before recommending any repair or replacement. ### Our Step-by-Step Flat Roof Process 1. Initial Inspection – We check for blisters, cracks, ponding water, and seam failures. We measure moisture levels with a non-invasive meter. This takes 30-60 minutes. 2. Diagnosis & Estimate – We explain what we found and give you two options: a targeted repair or a full replacement. Repairs typically run $300–$1,500. Full replacements cost $4–$8 per square foot, depending on material. 3. Material Selection – We carry TPO, EPDM, PVC, and modified bitumen. TPO is our most popular choice for San Ramon homes—it's energy-efficient and handles our hot summers well. EPDM is great for budget-conscious projects. PVC offers superior chemical resistance for commercial roofs. 4. Preparation – We remove debris, clean the surface, and apply primer if needed. For full replacements, we tear off the old membrane and inspect the deck for rot or damage. 5. Installation – Our crews follow manufacturer specifications to the letter. We use mechanical fasteners or fully adhered systems, depending on the roof deck. Seams are hot-air welded or chemically bonded. We flash all penetrations—vents, drains, skylights. 6. Final Inspection – We flood-test the roof to confirm no leaks. We walk the entire surface and check every seam. You get a written warranty and a maintenance schedule. ### Cost Ranges for Flat Roof Repair & Replacement - Minor patch repair: $300–$800
