Whatever your flat roofing need, our team has the product knowledge and installation expertise to deliver a watertight, long-lasting solution.
TPO Roofing
Thermoplastic Polyolefin (TPO) is the most widely specified single-ply roofing membrane in the commercial roofing industry today, and it is easy to understand why. TPO delivers an outstanding combination of energy efficiency, durability, and value that makes it the go-to choice for DFW commercial property owners and building managers.
TPO membranes are heat-welded at the seams using hot-air welding equipment, creating a continuous, monolithic waterproof surface that is actually stronger at the seams than in the field of the membrane. This welded seam technology is a significant advantage over mechanically fastened or adhesive-bonded seam systems, providing superior long-term leak resistance.
TPO Advantages:
- Energy Efficiency: Highly reflective white surface meets ENERGY STAR and Cool Roof Rating Council standards, reducing cooling costs by up to 30% in the DFW summer heat
- Chemical Resistance: Excellent resistance to oils, grease, and common rooftop chemicals from HVAC equipment
- Flexibility: Remains flexible in cold temperatures, resisting cracking during North Texas winter freeze events
- Multiple Thicknesses: Available in 45, 60, and 80 mil thicknesses for varying performance and warranty requirements
- Cost Effective: Lower material and installation costs compared to PVC while delivering comparable performance
PVC Roofing
Polyvinyl Chloride (PVC) roofing membranes represent the premium tier of single-ply flat roofing technology. PVC has a proven track record spanning over 50 years in commercial roofing applications worldwide, making it one of the most thoroughly tested and reliable flat roofing materials available.
PVC membranes are heat-welded at the seams just like TPO, but PVC offers several performance advantages that make it the preferred choice for demanding applications. PVC is inherently fire-resistant, has superior chemical resistance, and maintains excellent dimensional stability over its service life. For restaurants, manufacturing facilities, and buildings with rooftop grease exhaust systems, PVC is often the only membrane that can withstand the chemical exposure.
PVC Advantages:
- Superior Chemical Resistance: Withstands animal fats, vegetable oils, and chemical exhaust that degrade other membranes
- Fire Resistance: Self-extinguishing material that meets stringent fire code requirements without additional fire-retardant additives
- Proven Longevity: 50+ year track record with roofs installed in the 1960s still performing today
- High Reflectivity: White PVC membranes offer excellent solar reflectance for reduced cooling costs
- Weldable for Life: PVC seams can be re-welded during repairs decades after installation, unlike TPO which becomes more difficult to weld as it ages
EPDM (Rubber Roofing)
Ethylene Propylene Diene Monomer (EPDM) is a synthetic rubber membrane that has been the backbone of commercial flat roofing for over 60 years. EPDM is valued for its exceptional durability, flexibility, and resistance to UV radiation and ozone, two of the primary degradation factors for flat roofing materials in the intense North Texas sun.
EPDM membranes are available in large sheets that minimize the number of field seams, reducing potential leak points. The material is available in both black and white, with white EPDM offering enhanced solar reflectance for improved energy efficiency. EPDM can be fully adhered, mechanically attached, or ballasted depending on the building structure and project requirements.
EPDM Advantages:
- Proven Performance: 60+ year track record in commercial roofing with documented service lives exceeding 40 years
- UV & Ozone Resistance: Exceptional resistance to the degradation caused by intense Texas sun exposure
- Extreme Flexibility: Remains flexible at temperatures as low as -40 degrees, accommodating building movement and thermal cycling
- Large Sheet Sizes: Available in sheets up to 50 feet wide, minimizing seams on large commercial roofs
- Easy Repairs: Field repairs are straightforward using adhesive-applied patches, reducing long-term maintenance costs
Modified Bitumen Roofing
Modified bitumen roofing combines the proven reliability of traditional built-up roofing with the convenience of modern single-ply application methods. The asphalt-based membranes are reinforced with polyester or fiberglass and modified with APP (atactic polypropylene) or SBS (styrene-butadiene-styrene) polymers to dramatically improve flexibility, UV resistance, and weather performance.
Modified bitumen is an excellent choice for commercial buildings, multi-family properties, apartment complexes, and residential flat roof sections throughout the DFW area. The multi-layer redundancy of a modified bitumen system provides a margin of safety that single-ply systems cannot match, making it a popular choice for building owners who prioritize long-term reliability.
Modified Bitumen Advantages:
- Multi-Layer Protection: Two or more plies create redundant waterproofing that provides a safety margin against leaks
- Foot Traffic Resistance: Granule-surfaced cap sheets withstand regular maintenance foot traffic without damage
- Self-Healing Properties: SBS-modified membranes can self-seal around minor punctures and fastener penetrations
- Reflective Options: White granule and aluminum-coated cap sheets reflect solar heat for improved energy efficiency
- Proven in Texas: Decades of successful performance on DFW commercial and multi-family properties
Built-Up Roofing (BUR)
Built-up roofing, commonly known as BUR or "tar and gravel" roofing, is the original flat roofing system and has been protecting commercial buildings for over 100 years. BUR systems consist of alternating layers of bitumen (asphalt or coal tar) and reinforcing fabrics (felts or ply sheets) that are built up on the roof deck to create a thick, durable, multi-layer waterproof membrane.
The finished system is typically surfaced with a flood coat of asphalt and aggregate (gravel or slag) or a mineral-surfaced cap sheet. The gravel surface provides excellent protection against UV degradation, hail impact, and foot traffic, while adding significant ballast weight that enhances wind resistance.
BUR Advantages:
- Maximum Redundancy: Three to five layers of waterproofing create the most redundant system available in flat roofing
- Proven Track Record: 100+ year history with documented performance data spanning decades
- Hail Resistance: Gravel surfacing absorbs hail impact that would puncture single-ply membranes
- Low Maintenance: Thick, multi-layer construction tolerates minor damage without leaking
- Cost Effective: Competitive installed cost with a long service life of 20 to 30 years or more
Silicone Coating Systems
Silicone roof coatings have revolutionized flat roof maintenance and restoration. Rather than tearing off an aging flat roof and starting from scratch, a silicone coating system can be applied directly over the existing roof membrane, restoring waterproof integrity and adding years of service life at a fraction of the cost of a full replacement.
Silicone coatings are spray-applied or roller-applied in a seamless, monolithic layer that bonds directly to the existing roof surface. The cured silicone forms a highly reflective, UV-stable, waterproof barrier that sheds water and resists ponding, which is a common challenge on flat roofs in the DFW area. Silicone does not break down under standing water the way acrylic coatings do, making it the superior choice for flat roofs.
Silicone Coating Benefits:
- Ponding Water Resistance: Silicone will not degrade, soften, or lose adhesion under standing water
- No Tear-Off Required: Applied directly over existing roofing, eliminating costly and disruptive tear-off
- Energy Savings: Highly reflective white surface can reduce rooftop temperatures by up to 60 degrees
- Seamless Application: No seams means no potential leak points across the entire roof surface
- Renewable: Can be recoated at the end of its warranty period, extending roof life indefinitely
- Environmentally Friendly: Low VOC formulations meet the strictest environmental regulations
Elastomeric Coating Systems
Elastomeric roof coatings are flexible, rubber-like coatings that stretch and contract with the natural thermal movement of the roof substrate. The term "elastomeric" refers to the coating's ability to elongate and return to its original shape without cracking, bridging gaps and sealing minor surface defects as the roof expands and contracts through the extreme temperature swings common in North Texas.
Acrylic elastomeric coatings are the most common type and are an excellent choice for roofs with adequate drainage where ponding water is not a concern. They offer outstanding UV reflectance, good adhesion to a variety of substrates, and are available in a range of colors. For DFW property owners looking to extend the life of a metal, modified bitumen, or BUR roof, elastomeric coatings provide a cost-effective solution.
Elastomeric Coating Benefits:
- Flexibility: Stretches up to 300% to accommodate thermal movement without cracking or splitting
- UV Reflectance: Reflects up to 90% of solar radiation, significantly reducing cooling costs
- Substrate Versatility: Adheres to metal, modified bitumen, BUR, concrete, and spray polyurethane foam
- Cost Effective: Typically 50 to 70% less expensive than a full roof replacement
- Quick Application: Faster installation timeline means less disruption to your business operations
Ballasted Roofing Systems
Ballasted roofing systems take a different approach to flat roof installation. Instead of mechanically fastening or adhering the roofing membrane to the roof deck, the membrane is loose-laid over the substrate and held in place by the weight of ballast, typically river-washed stone, concrete pavers, or a combination of both.
This installation method offers several unique advantages for DFW commercial property owners. The ballast protects the underlying membrane from UV exposure, hail damage, and foot traffic, dramatically extending the membrane's service life. The stone or paver surface also provides excellent thermal mass that moderates rooftop temperatures, improving building energy efficiency.
Ballasted System Advantages:
- Membrane Protection: Ballast shields the roofing membrane from UV, hail, and physical damage
- Extended Membrane Life: Protected membranes can last 30 to 40+ years with minimal maintenance
- No Penetrations: Loose-laid installation eliminates fastener penetrations through the membrane
- Thermal Performance: Stone ballast provides thermal mass that reduces heat transfer into the building
- Wind Resistance: Ballast weight provides excellent wind uplift resistance on large, open roof areas
- Paver Options: Concrete pavers create a walkable roof surface for rooftop equipment access or outdoor amenity spaces
