TPO Roofing Systems

The ultimate energy-efficient, leak-proof single-ply membrane roofing system preferred by modern Texas warehouse and retail property owners.

System Specification Overview

Thermoplastic Polyolefin (TPO) is the fastest-growing commercial roofing choice in Texas. Metroplex Flat & Metal Roof Systems specializes in premium heat-welded TPO installations. We offer single-ply TPO membranes in standard 45-mil, 60-mil, and maximum-durability 80-mil thicknesses, featuring a heavy-duty polyester scrim reinforcement for superior tear and puncture resistance. Our crews deploy three main installation methods: Mechanically Attached (ideal for steel decks), Fully Adhered (using low-VOC bonding adhesive for ultimate wind uplift rating), and Ballasted systems. To comply with modern Texas building energy codes, we install thick, multi-layered Polyisocyanurate (Polyiso) or EPS insulation boards under the membrane, achieving high R-values (R-20 to R-30+) that lower HVAC stress and slash heating and cooling costs.

Key Engineering Benefits

  • Reflective Cool Roof Technology exceeding ENERGY STAR guidelines to reduce building cooling costs
  • Extremely durable heat-welded seams forming a single continuous watertight sheet stronger than the membrane itself
  • Outstanding resistance to ozone, chemical exposure, pooling water, and harsh Texas UV rays
  • Highly flexible single-ply sheet accommodating structural expansion and contraction
  • Industry-grade resistance to fungi, algae, mold, and environmental pollutants

System FAQ & Specifications

WHAT IS THE EXPECTED LIFESPAN OF A COMMERCIAL ΤΡΟ ROOF?
When professionally installed by certified contractors and supported by biannual preventative maintenance inspections, a high-quality 60-mil or 80-mil TPO roof typically delivers a reliable service life of 20 to 25 years.
While 45-mil is standard, we highly recommend 60-mil or 80-mil membranes for commercial buildings in Texas. Thicker membranes offer substantially higher puncture resistance against hail and severe weather debris.
Yes, easily. Compromised sections can be cut out, and a brand-new reinforced TPO patch is permanently heat-welded over the area, restoring the roof’s full watertight warranty.
