Flat roofs on commercial buildings deal with challenges residential roofs don't: rooftop HVAC units, exhaust fans, plumbing penetrations, satellite equipment, foot traffic, and ponding water. Dagmar Roofing & Maintenance has the training and equipment to handle all of it across Dagmar.
We install every major commercial roofing system: TPO single-ply, EPDM rubber membrane, PVC for chemical-resistant applications, modified bitumen for high-traffic roofs, and built-up roofing for proven long-term performance. Material selection depends on your building, budget, and specific exposure conditions.
Our Commercial Roofing Process
Commercial Roof Assessment
Before we recommend anything, we inspect everything. Membrane, seams, flashings, drains, penetrations, parapet walls, and rooftop equipment curbs. Core samples test for trapped moisture in the insulation. Honest assessment. No scare tactics.
Project Proposal
We present options when they exist: repair vs. replace, TPO vs. PVC, 15-year vs. 20-year warranty. Each option is priced so you can make an informed decision based on your budget and building plans.
Professional Installation
Factory-trained crews using proper equipment, hot-air welders for TPO/PVC, torch equipment for modified bitumen, and adhesive systems for EPDM. Every seam, flashing, and penetration detail inspected before we leave.
Warranty & Maintenance
Final roof inspection with photo documentation. Warranty paperwork provided. We recommend an annual maintenance plan to catch issues early and maintain warranty compliance.
