Which roof membrane has been reported to experience shattering problems in cold weather?

The roof membrane that has been reported to experience shattering problems in cold weather is PVC (Polyvinyl Chloride). PVC roofing systems are known for their durability and flexibility, but their chemical composition can become brittle when exposed to extreme cold temperatures. This brittleness can lead to the material cracking or shattering if subjected to impacts or heavy loads during cold weather conditions.

It is essential to consider the environmental conditions in which a roofing system will be installed and maintained. In regions that experience significant temperature fluctuations, the potential for PVC membranes to develop shattering issues in winter must be accounted for. This can affect the overall performance and longevity of the roofing system, making it crucial for roofing professionals to choose materials that are appropriate for the climate in which they are working.
