Flat and low-slope roofs are standard on Dallas commercial buildings and on residential additions built over garages or rear additions. Dallas Roof Master installs and repairs TPO, EPDM, and modified bitumen systems across Dallas. Flat roofs typically fail when seams separate or drains clog — our maintenance programs catch both issues before they become interior water damage. All flat roof work is backed by a 10-year workmanship warranty.
Flat and low-slope roofing systems require specialized membrane installation to achieve a watertight seal across the entire surface. Contractors install TPO (thermoplastic polyolefin), EPDM (ethylene propylene diene monomer), PVC membrane, modified bitumen, and built-up roof systems — selecting the right membrane for your building's needs, climate, and budget.
Installation begins with rigid insulation boards over the roof deck, providing thermal performance and a smooth substrate. The membrane is rolled out and adhered with adhesive, heat-welded at seams (TPO and PVC), or torch-applied (modified bitumen). Every parapet wall, drain, pipe penetration, and HVAC curb gets custom-fabricated flashing. For built-up roofs, we mop or spread alternating layers of bituminous felt and asphalt to build a multi-ply waterproof system. Reflective elastomeric coatings can be applied for additional UV protection and energy savings. All flat roof installations are verified for proper drainage slope and building code compliance.
