Single-ply roofs use a waterproof membrane made of synthetic polymer to prevent water damage and pooling on flat roof systems. However, this doesn’t mean the material is incapable of sustaining damage.
Understanding the problems that commonly plague single-ply roofs is the first step toward proper roof maintenance. Here’s a look at the most common issues.
1. Membrane Punctures
Regular foot traffic can damage any flat roofing material. Without a hard top layer, any single-ply membrane can be punctured from loose gravel, stepped-on screws or dropped blunt or sharp tools. Keeping nearby tree limbs short and observing proper care when walking and working on the rooftop can help prevent puncturing.
Temperature fluctuations brought about by perennial weather changes eventually take their toll on roofing materials. Thermal expansion and contraction can lead to fastening issues and seam failure. Be sure to pay attention to signs of minor shrinkage on the field membrane to carry out timely roof repair.
3. Improper Installation
One wrong detail during the installation of single-ply membranes can lead to long-term problems for the flat roofing systems. For instance, unsealed seams and laps expose the roof to not just moisture problems, but also to strong winds that can rip off a large portion of the membrane from the substrate.
4. Surface Blisters
Roof blisters are caused by moisture trapped beneath the roof surface. This issue results in adhesion loss of the roof membrane. Small or expanding blisters require immediate repairs, which is why you must talk to your trusted contractor to prevent moisture damage from spreading to the other areas of the roofing system.
