The Most Common Commercial Roofing Defects

Commercial roofing systems are designed to protect the building and its contents from weather-related damage. However, defects in the roofing system can lead to water infiltration, which can cause extensive damage to the building and its contents. Here are some of the most common commercial roofing defects.

Water Infiltration

Water infiltration is one of the most common commercial roofing defects. This can occur when there are cracks or gaps in the roofing system or when the flashing around chimneys, skylights, and other openings is not installed correctly. Water infiltration can cause extensive damage to the building and its contents, so it is vital to have your roof regularly inspected to identify any potential problems.

Ponding Water

Ponding water can occur when there is inadequate drainage on the roof or when the gutters are blocked. When ponding water occurs, it can cause the top to sag and eventually collapse. Ponding water can also lead to mold and mildew, which can cause health problems for the occupants of the building.



Another common commercial roofing defect is the build-up of debris on the roof. This can be caused by leaves and branches falling onto the roof or by animals nesting on the roof. Debris can block drains and gutters, leading to water infiltration and damage to the building.


If you notice any of these commercial roofing defects, a professional must inspect your roof as soon as possible. If the problem is not addressed, it could lead to further damage and expensive repairs.
