Commercial Roof Leak Detection: A Practical Guide for Colorado Businesses

Leaks in commercial roofs can lead to serious damage — from structural issues and interior water damage to costly downtime. Colorado’s freeze-thaw cycles, hailstorms, and heavy snowfall only make leak detection more critical. Whether you own a warehouse in Denver or manage a school in Fort Collins, spotting leaks early is essential to protect your investment.

Here’s what you need to know.

Why Roof Leaks Happen in Commercial Buildings

Commercial roofs are often flat or low-slope, which means water tends to collect instead of run off. Over time, that leads to vulnerabilities. Common causes include:

• Aging membrane systems (EPDM, TPO, PVC, BUR)

• Open seams or failed flashing

• Ponding water after rain or snow

• HVAC curb or skylight penetrations

• Storm damage — hail, wind, or freeze-thaw cracking

Signs of a Roof Leak You Can’t Ignore

Some leak signs are obvious. Others are subtle but just as serious. Watch for:

• Water stains on ceilings or walls

• Dripping during or after storms

• Mold, mildew, or musty odors

• Bubbling or discoloration on flat roof surfaces

• Spikes in heating or cooling bills (caused by wet insulation)

How Commercial Roof Leak Detection Works

Professional leak detection includes visual inspections and advanced tools:

1. Infrared Thermography

• Detects trapped moisture under membranes

• Useful for identifying “invisible” leaks without destructive testing

2. Electronic Leak Detection (ELD)

• Finds pinpoint leak sources in membrane systems

• Ideal for large flat roofs or roofs with solar arrays

3. Core Sampling

• Used to inspect wet insulation and measure water penetration

4. Water Testing / Flood Testing

• Confirms leak locations and evaluates drainage systems

Why Early Detection Matters

Delaying repairs increases cost. Wet insulation loses its R-value, metal decking corrodes, and mold spreads fast. Early leak detection helps:

• Lower repair costs

• Avoid interior damage

• Extend roof lifespan

• Reduce energy bills

• Maintain warranty compliance

FAQs: What Colorado Business Owners Ask

What’s the best way to find a commercial roof leak?

Start with a professional inspection using infrared or ELD testing. These methods find hidden damage under the membrane without tearing anything up.

How often should I inspect my commercial roof?

Twice a year — spring and fall — and after major hailstorms or wind events.

Can small leaks wait?

No. Small leaks grow, especially with Colorado’s temperature swings. Acting fast prevents structural damage.

Is leak detection covered by insurance?

If the leak is caused by a covered peril like hail or wind, yes — but documentation and early detection help support your claim.
