Flat roofs are commonly found in commercial buildings, and various types of roofing membranes are used for their construction. Among these, three popular options are EPDM, TPO, and PVC. PVC flat roof membranes offer several advantages, including the longest lifespan. In this article, we will explore the concept of PVC roofing, its characteristics, and how to extend its life expectancy.

What is PVC Roofing?

PVC Roofing Membranes

PVC roofing comprises rolls of roofing membranes made from polyvinyl chloride (PVC). These membranes play a vital role in creating a durable and long-lasting flat roof.

Layers and Support

A PVC roof consists of two layers, with polyester support added between them. This additional layer provides reinforcement and imparts flexibility to the roofing material, enhancing its overall performance.

Characteristics of PVC Roofing

Durability and Watertight Sealing

PVC roofs are renowned for their durability. The heat-welded seams of PVC roof membranes create an exceptionally strong and watertight seal, surpassing other types of membranes. Unlike alternative roofing systems, PVC roofs do not require tapes, caulks, or adhesives to seal their seams.

Wind Resistance

The welded seams of PVC roofs make them highly resistant to wind. In fact, PVC roofing systems can often withstand hurricanes of Category 3 intensity. If you reside in a hurricane-prone area with intense winds, PVC roofing is the optimal choice.

Fire and Chemical Resistance

PVC roofs exhibit excellent fire resistance, making them safer than many other roofing materials. Additionally, PVC roofing is highly resistant to oxidation and various chemicals. This resistance ensures the longevity of the flat roof, even when exposed to harsh chemicals.
