June 12th, 2024 BY First American Roofing

Maintaining the longevity and structural integrity of a commercial property is no small feat, especially when it comes to the roof. Scheduling routine roof inspections can help you:

Regular commercial roof inspections are essential to preemptively identify and address issues before they escalate into costly repairs or replacements. Keep reading for nine common issues that are found during commercial roof inspections and how to address them.

1. Roof Leaks

Roof leaks are one of the most common problems identified during a commercial roof inspection. They can be caused by various factors such as damaged or missing shingles, cracked flashing, or clogged drainage systems. Water infiltration can lead to significant property damage, including mold growth, structural weakening, and damaged insulation.

2. Ponding Water

Ponding water, or water accumulation, is another frequent issue in flat or low-sloped commercial roofs. It occurs when water does not drain properly and remains on the roof surface for more than 48 hours. Ponding water can lead to roof deterioration, structural damage, and even a collapsed roof.

3. Roof Surface Deterioration

Over time, exposure to environmental elements such as UV rays, rain, and wind can cause the roof surface to deteriorate. This can manifest as blistering, cracking, or the wearing away of roofing materials. If left unaddressed, it can lead to leaks and further damage.

4. Poor Installation

Improper installation of roofing materials can lead to a myriad of problems, including premature aging and failure of the roofing system. Issues stemming from poor installation include loose shingles, improper sealing, and inadequate underlayment.

5. Membrane Shrinkage

In single-ply roofing systems, membrane shrinkage is a prevalent issue. This occurs when the roofing membrane contracts, leading to pulled seams, cracks, and other forms of damage. Membrane shrinkage is primarily caused by prolonged exposure to UV rays and high temperatures.

6. Punctures and Penetrations

Punctures and penetrations in the roof can be caused by various factors including foot traffic, fallen debris, or installation of rooftop equipment. These openings can lead to water intrusion and other damage.

7. Blistering and Surface Bubbles

Blistering and surface bubbles occur when air or moisture gets trapped under the roof membrane. This can weaken the roofing system and make it more susceptible to damage.

8. Flashing Failures

Flashing failures are common problems in commercial roofs. Flashing is used to seal and protect joints and edges, but it can become damaged or deteriorated over time, leading to leaks.

9. Vegetation Growth

Vegetation growth on a roof, such as moss or algae, can retain moisture and lead to significant damage over time. It may also indicate poor drainage or standing water issues.
