Single Ply Roofing & Leak Detection: What Every Colorado Property Owner Needs to Know

Single Ply Roofing and Leak Detection: A Practical Guide for Colorado Property Owners

Single ply roofing is a popular choice across Colorado for both commercial and residential flat or low-slope roofs. If you manage a building in Denver, Colorado Springs, Fort Collins or anywhere across the Front Range, understanding this system — and how to detect leaks fast — can save you thousands in repairs.

Here’s what you need to know.

What Is Single Ply Roofing?

Single ply roofing systems are made from flexible sheets of synthetic material, most commonly:

• TPO (Thermoplastic Polyolefin)

• PVC (Polyvinyl Chloride)

• EPDM (Ethylene Propylene Diene Monomer rubber)

These membranes are installed in a single layer over insulation or decking, making them lightweight and relatively quick to install.

Why single ply is popular in Colorado:

• Excellent UV and weather resistance

• Performs well under freeze-thaw cycles

• Cost-effective for large surface areas

• Can be mechanically fastened or fully adhered

• Energy efficient when white reflective surfaces are used

What Causes Leaks in Single Ply Roofs?

Even high-performing single ply roofs can develop leaks over time. The most common causes include:

• Punctures from foot traffic or dropped tools

• Seam failures due to poor welding or material fatigue

• Shrinkage (especially with older EPDM roofs)

• Membrane aging after long-term UV exposure

• Clogged drainage leading to standing water and membrane damage

Colorado’s wide temperature swings and hail events accelerate wear and tear — so early detection is critical.

How Is Leak Detection Performed?

Modern leak detection for single ply roofs has improved dramatically. Here are the top methods used in Colorado:

1. Electronic Leak Detection (ELD)

This is the most advanced and non-destructive way to pinpoint even tiny breaches in membranes. It works by detecting electrical current paths through wet insulation or punctures.

2. Infrared Thermography

Infrared cameras spot moisture trapped below the membrane by detecting heat differences. Best used at night or early morning for accuracy.

3. Flood Testing (Conductive Dye)

Water mixed with a visible dye is spread across the surface to spot active leaks. More time-consuming, but still used on small sections.

4. Visual Inspection with Probes

Trained professionals walk the roof and use moisture meters or seam probes to find problem areas.

Benefits of Proactive Leak Detection

Leak detection isn’t just for emergencies. Here’s why regular testing matters:

• Prevents structural damage to insulation and decking

• Avoids mold and moisture damage inside the building

• Helps maintain roofing warranties

• Supports long-term asset planning and budgets

• Reduces insurance claims from water damage

At Roof Nuts CO, we recommend having your single ply roof inspected and tested at least once a year — especially before winter or after hailstorms.

FAQs About Single Ply Leak Detection

How do I know if my roof needs leak detection?

If you see interior staining, blistering, or bubbling in the membrane — or if your roof is over 10 years old — it’s time.

Can leak detection be done on a wet roof?

Yes. In fact, ELD and infrared testing often work best with some moisture present.

What does leak detection cost?

Most commercial properties can expect to pay between $500 and $1,500 depending on roof size, access, and method.

Does insurance cover leak detection?

Sometimes — especially if tied to storm or hail damage. We help Colorado owners navigate this with their adjusters.
