Las Vegas Commercial Roofing Contractors
Roof penetrations, equipment curbs, repairs, and replacements for Las Vegas commercial buildings.
Tenant improvements often reach the roof. New rooftop units, exhaust fans, and plumbing vents all create penetrations, and every one of them has to be flashed so it stays dry through summer heat and monsoon storms.
Our network’s commercial roofing contractors work with owners and general contractors on roof work tied to build-outs, as well as repairs and replacements on retail centers, office buildings, and industrial property across the valley.
Roof Work During a Build-Out
Common roofing tasks on a tenant improvement include:
- Curbs and flashing for new rooftop units
- Exhaust fan and hood penetrations
- Plumbing vent flashing
- Removing and patching abandoned openings
- Protecting the roof during equipment lifts
Using a roofer approved by the owner can keep the existing roof warranty intact.
Roof Systems in Las Vegas
Commercial roofs in the valley use several systems:
- Spray polyurethane foam with a protective coating
- TPO and PVC single-ply membranes
- Modified bitumen
- Built-up roofing on older buildings
- Tile and metal on some retail and hospitality buildings
Repairs should match the existing system so the roof performs as one assembly.
Heat and UV Exposure
Intense sun is hard on roofing materials:
- Reflective coatings that lower roof temperatures
- Recoating foam roofs on a regular schedule
- Checking seams and flashing for heat damage
- Protecting walk paths to equipment
- Planning work for cooler hours
A reflective roof can also reduce the cooling load on the space below.
Monsoon Readiness
Summer storms can bring heavy rain in a short time:
- Clear drains, scuppers, and gutters
- Sealed penetrations and curbs
- Crickets to move water off low areas
- Inspection after major storms
- Emergency leak response
Getting ahead of monsoon season protects new finishes inside the space.
Coordination With Other Trades
Roof work touches several other scopes:
- HVAC equipment replacement and new curbs
- Structural review for added equipment weight
- Electrical and gas lines to rooftop units
- Fall protection for workers
- Owner approval for any roof changes
The general contractor sequences roofing so penetrations are sealed before interior finishes go in.
Inspections and Warranties
Good roofing work is documented:
- Pre-work roof condition photos
- Manufacturer warranty requirements
- Permit and inspection where required
- Final walk of all new penetrations
- Closeout photos and reports
Clear records make future repairs and warranty claims simple.
Frequently Asked Questions
Will a new rooftop unit affect my roof warranty?

What type of roof is most common in Las Vegas?
Spray foam and single-ply membranes like TPO are very common on commercial buildings in the valley, along with modified bitumen and built-up roofs on older properties.

Ideally before interior finishes go in and ahead of monsoon season, and during cooler morning hours in summer.
