Thermoplastic polyolefin, or TPO roofing, is a lightweight and energy-efficient single-ply membrane recognized for its durability. It offers resistance to punctures, tears, UV rays, and chemicals, making it an ideal choice for protecting flat roofs. The installation process of a TPO roof involves heat welding that creates watertight seals between sheets. TPO roofing is also well-suited for low slope roofs, providing a durable and energy-efficient solution.

TPO roofs are well-suited for cooler climates and can provide up to 20 to 30 years of service if properly maintained. Regions with significant snowfall or frequent freeze-thaw cycles may adversely affect the performance of TPO roofing systems due to their specific environmental vulnerabilities.

PVC Roofing

PVC roofing, crafted from a pliable and fire-resistant thermoplastic substance, comes in an array of thicknesses and hues. Renowned for its longevity as well as its resilience against chemical exposure, PVC roofing has the potential to endure up to three decades with appropriate upkeep. It is UV resistant and aptly fits flat roofs across diverse environmental conditions. PVC roofing is also a viable option for low slope roofs, offering longevity and chemical resistance.

The installation process for PVC roofing accommodates either adhesive bonding or the use of mechanical fasteners, thereby rendering it adaptable for various structures. Nevertheless, this type of roofing is not recommended for steeply pitched rooftops or regions that experience substantial snow accumulation.

Liquid Applied Roofing

Liquid roofing, also known as liquid-applied roofing, is becoming increasingly favored owing to its straightforward application process and adaptability. It forms a uniform, impermeable elastomeric coating that can be applied over various substrates. This method of installation requires only basic tools, resulting in less interruption and easier accessibility during the implementation phase. Liquid applied roofing is also suitable for low slope roofs, providing a seamless and adaptable solution for various roofing needs.

A notable benefit of this type of roofing is its capacity to prolong an existing roof’s lifespan by adding a protective overlay on top of aging materials. These systems have the remarkable ability to become waterproof within a short span ranging from 10 minutes up to one hour after application, subject to weather conditions. Liquid membranes are exceptionally efficient for roofs with intricate designs where they provide excellent protection against water seepage.
