Whether it's a residential flat section over a room addition, a garage with a flat top, or a full commercial building, San Joaquin Roofing & Maintenance handles flat roofing in San Joaquin with the same attention to detail. TPO for reflectivity, EPDM for budget, PVC for chemical resistance, modified bitumen for foot traffic.
EPDM (rubber roofing) has a 50-year track record as a proven flat roofing membrane. Fully adhered EPDM over polyiso insulation is a reliable, cost-effective choice for San Joaquin property owners who want proven performance without the premium price of TPO or PVC.
Our Flat Roofing Process
Membrane Assessment
We inspect the membrane surface, seam integrity, flashing condition, penetration seals, drain function, and overall drainage pattern. Core samples reveal whether the existing insulation is dry or waterlogged. Full findings provided in a written report.
Detailed Proposal
Your proposal includes membrane type, insulation R-value, drainage design, and warranty coverage. If multiple options make sense, we price all of them so you can compare and choose what fits your budget and goals.
Professional Installation
Insulation board cut and installed with staggered joints. Membrane installed over insulation per manufacturer specs. All penetrations (pipes, vents, HVAC curbs) receive custom-fabricated flashing. Drains and scuppers cleared and properly connected to the new membrane system.
Warranty & Drainage Test
Final roof inspection with drainage verification. Warranty paperwork provided. We recommend a maintenance plan to keep your flat roof performing and your warranty valid for its full term.
