Commercial Roof Types in Austin, TX
Commercial roofing isn't one-size-fits-all. The right system depends on your building type, slope, budget, and how long you plan to hold the property. Here's an honest look at every system we install.
TPO (Thermoplastic Polyolefin)
Advantages
- + Most widely installed commercial membrane in the U.S.
- + White reflective surface reduces cooling costs 15–30%
- + Heat-welded seams — strongest joint method available
- + Energy Star rated, may qualify for utility rebates
- + Excellent UV and chemical resistance
Considerations
- − Requires qualified installers for proper seam welding
- − Lower puncture resistance than EPDM at equivalent thickness
- − Some older formulations had durability issues — specify 60-mil or 80-mil
Our take: Our most recommended flat roof system for Austin commercial properties. The combination of reflectivity, seam strength, and cost makes it the best all-around performer in Central Texas heat.
Full Details →EPDM (Ethylene Propylene Diene Monomer)
Advantages
- + Proven track record — widely used for over 50 years
- + Excellent flexibility in cold temperatures
- + Resistant to UV, ozone, and weathering
- + Lower material cost than TPO in some configurations
Considerations
- − Black surface absorbs heat — poor choice for Austin heat without white coating
- − Seams are glued or taped, not welded — higher long-term leak risk
- − Petroleum oils degrade EPDM — avoid near HVAC condensate discharges
Our take: A solid system in moderate climates, but TPO's welded seams and reflective surface give it a meaningful advantage in Austin. We install EPDM when the application specifically calls for it.
Modified Bitumen
Advantages
- + Multi-ply construction provides redundancy
- + Torch-applied SBS systems are highly waterproof
- + Granulated cap sheet adds impact resistance
- + Performs well over uneven or irregular decks
Considerations
- − Torch application creates fire risk — requires experienced installers
- − Darker surface absorbs heat unless coated
- − Heavier than single-ply — may require structural verification
Our take: Common on older Austin commercial buildings. Many are candidates for a silicone coating to extend life rather than full replacement. We assess each roof individually.
Standing Seam Metal
Advantages
- + Longest commercial roof lifespan available
- + Class 4 hail resistance in most profiles
- + Minimal maintenance over its life
- + Reflective coatings available for energy performance
- + Strong resale signal for commercial properties
Considerations
- − Highest upfront material and installation cost
- − Expansion noise in temperature extremes
- − Requires experienced panel installers for proper clip and float detail
Our take: Best life-cycle cost for buildings with 20+ year hold periods. The premium upfront cost is typically recovered within 15 years compared to two successive TPO replacements.
Full Details →Spray Polyurethane Foam (SPF)
Advantages
- + Monolithic application — no seams, no joints, no flashings to fail
- + Fills and levels irregular surfaces and eliminates ponding areas
- + Insulation and waterproofing in one application
- + R-value of 6–7 per inch — significant energy savings
Considerations
- − Requires a protective topcoat (typically silicone) that must be reapplied every 10–15 years
- − Sensitive to wind and humidity during application — weather window required
- − Cannot be visually inspected for interior wet spots after application
Our take: Excellent for buildings with complex rooftop geometry, ongoing ponding problems, or a desire for maximum insulation. Becoming increasingly popular on Austin area churches and institutional buildings.
Built-Up Roofing (BUR)
Advantages
- + Multi-ply redundancy — multiple layers of protection
- + Excellent for high foot-traffic rooftops
- + Proven system with decades of performance data
Considerations
- − Heavy — structural requirements must be verified
- − Slow installation process
- − Not commonly specified on new construction in Austin
- − Repairs can be complex depending on ply count
Our take: Rarely specified for new Austin commercial construction today, but we replace and repair existing BUR roofs across Central Texas. Recover systems are often an economical option when the existing BUR is in serviceable condition.
