Common Commercial Roofing Problems and How to Spot Them

Commercial roofs are exposed to various environmental stressors, which can lead to a range of problems over time. Regular roof inspections and maintenance are crucial in identifying and addressing these issues early, preventing costly repairs, and extending the life of your roof. In this post, we’ll explore some of the most common commercial roofing problems and provide tips on how to spot them.

1. Water Ponding

Water ponding occurs when water accumulates on the roof surface and doesn’t drain properly. This can lead to structural damage and leaks.
After a rainfall, check for standing water on the roof that doesn’t drain away within 48 hours. Look for signs of water stains or algae growth.
Ensure that roof drains and gutters are clear of debris. Consider installing additional drainage systems if ponding is a recurring issue.

2. Leaks and Moisture

Leaks are one of the most common issues in commercial roofing and can be caused by various factors, including damaged membranes, flashing, or seals.

Look for water stains on ceilings and walls, mold growth, and damp insulation. Conduct regular interior inspections, especially after heavy rain.

Seal any cracks and replace damaged membranes or flashing. Regular maintenance and prompt repair of minor issues can prevent major leaks.

3. Blistering and Bubbling

Blisters and bubbles form when air or moisture gets trapped between the roof layers, causing the materials to expand and separate.
Inspect the roof surface for raised areas or bubbles. These are often more noticeable during warm weather when materials expand.
Remove the affected areas and apply new roofing material. Ensure proper ventilation and adherence during installation to prevent recurrence.

4. Punctures and Tears

Punctures and tears can occur due to foot traffic, falling debris, or weather conditions, compromising the roof’s integrity.

Perform a visual inspection for visible tears, punctures, or areas where the roof membrane appears damaged.

Repair or replace the damaged sections immediately to prevent leaks and further deterioration. Consider using protective walkways on high-traffic areas.

5. Shrinkage

Shrinkage happens when the roofing membrane contracts, leading to cracks, tears, and gaps around flashings and penetrations.
Check for signs of pulling or stretching at roof edges, seams, and around penetrations. Look for gaps between the membrane and roof edges.
Repair any affected areas and monitor for ongoing shrinkage. Replace severely shrunken membranes to prevent extensive damage.

6. Roof Membrane Issues

The roof membrane can suffer from wear and tear over time, leading to cracks, punctures, and other issues.
Look for visible signs of damage such as cracks, holes, and worn spots. Check seams and edges for separation.
Repair minor damages promptly and consider a roof membrane replacement if extensive damage is found.

Regular roof inspections and maintenance are essential in identifying and addressing common commercial roofing problems. By spotting issues early and taking corrective actions, you can extend the life of your roof and avoid costly repairs.
