4 Common Problems Associated with Single-Ply Membrane Commercial Roofing Systems
Although one of the most popular and durable commercial roofing materials out there, the single-ply membrane is also prone to damages and requires repair and maintenance work at regular intervals. Over time, due to age, regular wear and tear, and harsh weather conditions, a variety of problems can arise in your single-ply membrane roof. Here are the 4 common ones-
Shrinkage and Seam Failure
As the single-ply membrane material ages, it becomes brittle and loses elasticity. It shrinks and places additional stress on flashings, resulting in tears to the membrane or flashing that has pulled away–ultimately leading to seam failure and membrane cracks. Seam failure also can result from improper installation techniques that lead to seam voids or bad welds.
All types of single-ply roofing, whether it is TPO (Thermoplastic Polyolefin), PVC (Polyvinyl Chloride), or EPDM (Ethylene Propylene Diene Monomer), are subject to damage from wind uplift. If the membrane attachment method is deficient or the uplift is severe enough, a strong wind can tear off portions of the membrane. Although the wind is the main culprit for this problem, the cause can also include delamination of the roof’s core due to improper installation, adhesive failure, or water penetration. Depending on the size of the affected area, the best roofing repairers in Austin, TX can reattach the membrane by making use of plates and screws. In the worst-case scenario, the roof might require removal and installation of a new section of the membrane.
Single-ply membrane roofing does not have a solid hard-top layer that can protect the synthetic rubber from dropped tools or gravel, or loose screws from being pushed into the rubber membrane. This kind of damage could puncture the membrane in the rubber, making your roof vulnerable to leaks.
While TPO and PVC single ply systems are welded by hot air, EPDM single ply membranes seams are joined by adhesive. Blisters are essentially a loss of adhesion of the roof membrane from the underlying roofing material. They are usually the result of moisture trapped beneath the roof surface. While small blisters are relatively easy to deal with, larger or expanding blisters are an indication of the presence of additional moisture below the membrane, which can cause even further damage to your single-ply membrane roof.
