The Most Common Commercial Roofing Problems And How To Fix Them

Jan 25, 2025 | 0 comments

Commercial roofing systems are essential for protecting your business, employees, and investments. However, these roofs face constant exposure to harsh weather, fluctuating temperatures, and foot traffic — all of which can lead to damage over time. Understanding the most common commercial roofing problems and how to fix them can help you save on costly repairs and extend the lifespan of your roof.

In this blog, we’ll walk you through the most frequent issues with commercial roofs and provide professional insights on how to address them effectively. Whether you’re dealing with minor leaks or major structural issues, Iron Shield Roofing is your trusted partner for commercial roofing in Edmonton.

1. Roof Leaks and Moisture Infiltration

The Problem:

One of the most frequent issues with commercial roofs is water leakage, often caused by ageing materials, cracked flashing, poor drainage, or punctures from foot traffic or debris.

The Fix:

Start with a thorough roof inspection. Identify leak sources and seal them using commercial-grade waterproofing materials. In more severe cases, consider a partial or full roof replacement.

Pro Tip: Schedule regular inspections with a certified commercial roofing company to catch leaks before they cause internal damage.

2. Ponding Water

The Problem:

Flat or low-sloped roofs can accumulate standing water after rain or snow. This can lead to membrane degradation and increased roof load.

The Fix:

Ensure proper drainage by cleaning and maintaining gutters and downspouts. If necessary, re-slope the roof or install additional drains.

Need expert help? The commercial roofing experts at Iron Shield Roofing can assess your roof’s drainage system and recommend tailored solutions.

3. Blistering and Bubbling

The Problem:

Blisters and bubbles occur when air or moisture becomes trapped under the roof membrane. This can weaken your roofing system and lead to leaks.

The Fix:

Minor blisters can sometimes be cut and patched, but widespread blistering may require re-roofing.

4. Flashing Failures

The Problem:

Flashing — the metal strips used around roof edges, vents, and HVAC systems — can pull away or corrode over time, allowing water intrusion.

The Fix:

Replace or reseal damaged flashing. Use high-quality materials that are designed to withstand Alberta’s climate extremes.

5. Membrane Shrinkage or Cracking

The Problem:

Some roofing membranes shrink or crack due to UV exposure and ageing, putting strain on seams and causing roof splits.

The Fix:

Inspect your roof membrane regularly. Early-stage cracks can often be patched. For more extensive shrinkage, a new membrane installation may be required.

6. Poor Installation

The Problem:

Improper installation can lead to a host of long-term issues, including leaks, weak seams, and system failure.

The Fix:

Only work with experienced and certified commercial roofing contractors. Poor installation often leads to costly repairs down the road.

7. Punctures and Surface Erosion

The Problem:

Heavy equipment, tools, or even foot traffic can puncture the roof membrane or erode its protective surface.

The Fix:

Conduct routine roof inspections and enforce a rooftop maintenance plan. Install protective walk pads where foot traffic is frequent.

8. Wind and Storm Damage

The Problem:

Strong winds and storms in Edmonton can tear away roof materials or lift edges, leaving areas vulnerable to water damage.

The Fix:

Inspect after every major storm. Promptly repair loose or missing sections. Reinforce your roof with wind-resistant materials.

9. Vegetation Growth

The Problem:

Moss, algae, and even small plants can take root in clogged drains or damp areas, compromising roof integrity.

The Fix:

Keep your roof clean and clear of debris. Schedule seasonal maintenance with a trusted commercial roofing company.

10. Ageing and Lack of Maintenance

The Problem:

Over time, even the best roofs begin to wear out. Without proper maintenance, small problems escalate into major expenses.

The Fix:

Create a long-term maintenance plan. Bi-annual inspections, timely repairs, and upgrades will help maximize your roof’s life expectancy.
