Denver Flat Roofing Contractor for Commercial Properties

Q: Is TPO or EPDM better for Denver commercial buildings?

Both systems are effective, but TPO (Thermoplastic Polyolefin) is often preferred in Denver for its reflective white surface, which repels UV rays and lowers summer cooling costs. However, EPDM (rubber roofing) is extremely durable against large hail and remains flexible in sub-zero temperatures. We often recommend EPDM for buildings in areas with high hail risk and TPO for businesses prioritizing energy efficiency.

Q: How often should I inspect my commercial flat roof?

You should schedule professional flat roof inspections twice a year: once in the spring (to check for winter freeze-thaw damage) and once in the fall (to clear drains before snow). Additionally, you should always inspect the roof after any major weather event, such as a heavy hailstorm or windstorm, to catch acute damage early.

How much does commercial flat roof replacement cost in Denver?

In the Denver metro area, commercial flat roof replacement typically ranges from $6.00 to $12.00 per square foot for single-ply membrane systems like TPO or EPDM. Costs can vary based on the thickness of the insulation (R-value) required by code, the ease of access to the roof, and whether the existing roof needs to be fully torn off or if a layover is permitted.

How long do commercial flat roofs last in Colorado?

Due to Colorado’s high UV exposure and freeze-thaw cycles, a well-installed commercial flat roof generally lasts 20 to 25 years. Regular maintenance is critical; unmaintained roofs may fail in as little as 15 years, while systems with consistent preventative care can extend their lifespan to 30 years.

Is TPO or EPDM better for Denver commercial buildings?

Both systems are effective, but TPO (Thermoplastic Polyolefin) is often preferred in Denver for its reflective white surface, which repels UV rays and lowers summer cooling costs. However, EPDM (rubber roofing) is extremely durable against large hail and remains flexible in sub-zero temperatures. We often recommend EPDM for buildings in areas with high hail risk and TPO for businesses prioritizing energy efficiency.

Does insurance cover hail damage to commercial flat roofs?

Yes, most commercial property insurance policies cover hail damage, but coverage depends on the extent of the damage and your specific policy limits. It is critical to schedule a professional inspection immediately after a storm, as hail damage on flat roofs (such as bruised insulation or micro-fractures in the membrane) is often invisible to the untrained eye but leads to major leaks later.

How often should I inspect my commercial flat roof?

You should schedule professional flat roof inspections twice a year: once in the spring (to check for winter freeze-thaw damage) and once in the fall (to clear drains before snow). Additionally, you should always inspect the roof after any major weather event, such as a heavy hailstorm or windstorm, to catch acute damage early.
