The 6 Common Problems of Single-Ply Roofing Systems

Compared to residential roofs, commercial roofing systems can be a bit challenging to maintain. This is because single-ply roofing systems tend to face more issues compared to the likes of asphalt or slate roofs. With that in mind, it’s important that you learn what the characteristics are of these single-ply roofing systems.

In this post, The Great American Roofing Company, a leading commercial roofing company with a reasonable roof repair cost, discusses the six common problems you can usually see in single-ply roofs.

1. Blisters – Blisters are the loss of adhesion in one part of the roofing membrane from the roofing material beneath it. This is often due to moisture trapped beneath the surface of the roof. While small blisters can be left alone and monitored, the larger ones are indicators of additional moisture below the membrane and can cause further damage. To rectify this, work only with qualified roofing contractors.

2. Shrinkage – Over time, your roofing membrane will lose its elasticity due to its age. This will cause the membrane to shrink and place stress on your flashings, which can result in tears to the roofing system.

3. Seam Failure – As single-ply membranes can shrink, this adds stress to the seams of the membrane and will often result in failure. This can easily compromise the integrity of your roofing system. Once you notice this occurring, contact a roofing professional with the necessary experience to fix your roof.

4. Attachment Failure – Single-ply roofing system are vulnerable to wind uplift damage because if the uplift is severe enough, portions of the membrane can be torn off. While it’s possible for a roofer to reattach these membranes with plates and screws, if the affected area is large in size, installation of a new membrane section may be required. If this is the case, consider working with only the best roofers to repair the roof.

5. Unexpected Foot Traffic – Single-ply roofs are extremely vulnerable to high foot traffic as plastic soles and rubber synthetics can easily puncture through the membranes and cause damage. With that in mind, consider using protective mats to shield your roof against high foot traffic or only allow experienced maintenance personnel on your roof to minimize foot traffic as much as possible.

6. Poor Installation – During the installation of your single-ply roof, it’s possible for the installation to go wrong and cause long term problems. If your contractor fails to cut the right seam size, it can create gaps that can allow leaks onto your building. Improper welding, meanwhile, can either cause insufficient melting or over-melting. Both can cause structural damage to your roof in the long run. To prevent poor installation, only hire a contractor that has the correct amount of experience with single-ply roofs.
