Common Commercial Roof Failures and Signs of Potential Issues with Commercial Membrane Roofs
Roof Membrane Punctures
Punctures or holes in the roof membrane material can occur for a variety of reasons, material penetration from tree limbs, penetration from worker error, poorly mounted or installed rooftop HVAC equipment, etc. These punctures can be repaired by fusing or welding new membrane material
Open seams can occur when the roof membrane deteriorates due to issues or age. These can also be fixed with welding or fusing and replacement of membrane material
Pooling or Ponding Water
When roof drains fail, rain water tends to pool or “pond” in areas of the roof and standing water on your roof can be a major issue and lead to accelerating roof deterioration. Having your drains inspected for blockage and having any blockage cleared is the first step
Blocked or Clogged Roof Drains
Blocked or clogged roof drains, including roof downspouts and gutters can cause issues with pooling or ponding water on the roofs surface that will lead to roof leakage, and accelerated roof material deterioration
Bridging walls on the roof are usually a sign that the roof is is nearing it’s age out, and considerations for a roof replacement should be considered or discussed. It can also be from poor initial installation. This can be repaired if this is the case.
Fastener Failure and Backout
When the membrane fails and water penetrates the surface material the roof contracts and expands more than the tolerances allowed forcing the fasteners to “backout” and creating a situation where the roofing envelope is compromised. These fasteners must be replaced after a full inspection of the roofing sub base and membrane are inspected and repaired as necessary.
This is the most common commercial roof failure with membrane roofs and occurs when caulk ages. This can lead to serious roof issues if left unchecked. Annual roof inspections can help you determine when roof caulking needs to be repaired and replaced. This is also one of the easiest roof repairs to make as it entails removing the old caulk, cleaning the locations, and resealing with new caulking.
Blisters occur when air gets trapped under the membrane. This requires the removing of the affected area, alleviation of the blister, and the replacement of new membrane material that is fused or welded in place with manufacturers approved processes.

- Failing shingles
