Commercial, Industrial and industrial properties are frequently exposed to severe weather conditions, which can significantly impact the integrity of their roofing systems. With cold winters that bring snow and ice, followed by hot summers in Southwestern Ontario that can lead to thermal expansion, it's essential to choose a roofing material that can withstand these extremes. Two popular options for flat roofing systems are PVC (Polyvinyl Chloride) and TPO (Thermoplastic Olefin). To help you make informed decisions for your building, it’s important to consider some key differences between both materials. Material Composition
PVC roofing is made from a blend of polyvinyl chloride resin and various additives, including plasticizers and stabilizers. This composition gives PVC roofing its flexibility and durability. On the other hand, TPO roofing is composed of a single-ply membrane made from a blend of polypropylene and ethylene-propylene rubber. This combination results in a lightweight, flexible roofing material that is also resistant to UV rays and chemical exposure.
Durability
PVC roofing is known for its long lifespan, often lasting 20 years or more with proper maintenance. It is highly resistant to punctures, tears, and impacts, making it a suitable choice for commercial buildings that may experience foot traffic or equipment placement on the roof. TPO roofing, while slightly less durable than PVC, still offers a robust solution for flat roofs. It can withstand various weather conditions and is resistant to mould and algae growth. However, TPO may not have the same longevity as PVC, with an average lifespan of 15 to 20 years. It's essential to consider your building's specific needs and the potential for wear and tear when choosing between these two materials.
Energy Efficiency
TPO roofing is particularly well regarded for its energy-efficient properties. Its reflective surface helps reduce heat absorption, which can lead to lower energy costs during the hot summer months. This feature can be especially beneficial in Southwestern Ontario, where the summer sun can create significant cooling demands. PVC roofing also offers energy-efficient options, but its performance may vary based on the thickness and colour of the membrane. While both materials can help reduce energy costs, TPO often takes the lead in this category due to its superior reflective capabilities.
Installation
Installation processes for PVC and TPO roofing can differ significantly. PVC roofing is typically installed using a hot-air welding method, which creates strong seams and ensures a watertight seal. This method requires skilled labour and can be more time-consuming. In contrast, TPO roofing is often installed using mechanical fasteners or adhesive, making the installation process quicker and easier. This can result in lower labour costs and faster project completion times, which may be appealing to building owners looking to minimize disruption.
