Commercial roofing in Las Vegas means flat and low-slope systems operating under 115°F summer heat, monsoon debris loads, and HVAC equipment traffic that residential systems never face. The contractors who do this well are licensed for both residential and commercial, understand membrane systems, and carry the liability coverage to work on occupied buildings.
Commercial roofing systems we install and repair in Las Vegas
TPO (Thermoplastic Polyolefin) — most common
TPO is the dominant flat roofing membrane in Las Vegas commercial construction. White or light-colored membranes reflect 80%+ of solar energy, dramatically reducing building cooling loads. Heat-welded seams create a watertight bond that outperforms adhesive systems. Lifespan: 15–25 years with proper maintenance. Best for: retail, office, warehouse, and light industrial.
EPDM (Ethylene Propylene Diene Monomer)
The "black rubber roof" — durable, flexible, and cost-effective. EPDM handles thermal cycling exceptionally well and resists ozone degradation common in dry desert climates. Seams require adhesive or tape rather than heat welding. Lifespan: 20–30 years. Best for: large low-slope areas, older commercial buildings, budget-sensitive projects.
Modified Bitumen (Mod-Bit)
Asphalt-based membrane system with reinforced fleece backing. Torch-applied or cold-adhesive systems available. Common in Henderson and North Las Vegas warehouse and industrial stock from the 1980s–2000s. Lifespan: 15–20 years.
Acrylic and silicone roof coatings
For commercial roofs in good structural condition with minor surface wear, elastomeric coatings extend membrane life 10–15 years at a fraction of replacement cost. We assess the existing membrane before recommending a coating — not every roof is a good coating candidate.
Commercial roof maintenance programs
Las Vegas commercial property owners and managers benefit significantly from annual roof inspections and scheduled maintenance. Common commercial maintenance items include:
- Drain cleaning and flow testing before monsoon season
- Seam inspection and re-welding at separation points
- HVAC curb flashing inspection
- Penetration sealant inspection and replacement
- Coating touch-up at high-traffic areas
Commercial roof repair vs replacement decision
- Membrane is under 15 years old
- Damage is localized (under 25% of field)
- Seams are generally sound
- Drainage is adequate
- No ponding water issues
- Membrane is past rated life
- Multiple failures across field
- Decking is compromised
- Drainage cannot be corrected
- Repair cost exceeds 30% of replacement
