What is a Triflex Roof System?
When it comes to protecting a flat roof, the quality of the waterproofing system is everything. A durable, flexible and long-lasting solution can make the difference between a roof that performs for decades and one that constantly demands repairs. One of the most reliable solutions available today is the Triflex roof system — a high-performance, cold-applied waterproofing system known for its durability, flexibility and exceptional weather resistance. Below, we break down what it is, how it works, and why it’s becoming a preferred choice for both domestic and commercial properties.
A Seamless, Liquid-Applied Waterproofing SystemAt its core, a Triflex roof system is a cold liquid-applied waterproofing membrane. Unlike traditional sheet-based systems that rely on seams or joints, Triflex forms a fully seamless membrane once cured. This eliminates weak points where water can penetrate and ensures thorough protection, even on roofs with awkward details or complex shapes. Because it is applied as a liquid, it can easily bond to corners, penetrations, edges and upstands — making it ideal for roofs with pipes, vents and skylights.
Cold-Applied for Safer InstallationOne of the biggest advantages of a Triflex system is that it’s applied without the use of heat or flames. This makes installation safer, reduces the risk of fire, and allows it to be used on buildings where traditional hot-works roofing methods would be unsuitable. The system also cures rapidly, meaning it becomes rainproof and usable in a much shorter time than many alternatives. For clients, this means less interruption and faster project completion.
Designed for Long-Term DurabilityA Triflex roof system is engineered to withstand the toughest conditions. Once cured, the membrane is:
Highly flexible – able to accommodate building movement without cracking UV-resistant – maintaining durability and colour over time Weatherproof – resisting wind, rain, ice, and standing water Impact-resistant – suitable for areas that receive foot traffic Its robust reinforcement layer also helps it handle structural movement, making it suitable for both new roofs and refurbishment projects. Compatible With a Wide Range of Roof Types Another key benefit of Triflex is its versatility. It can be applied to a variety of substrates, including: Concrete Bitumen Asphalt Metal Timber Single-ply membranes This makes it an excellent choice for refurbishing ageing roofs as well as for new constructions. Its versatility allows installers to specify the exact build-up needed for each project. Perfect for Details and Difficult Areas Where many roofing systems struggle — such as at junctions, penetrations, gutters, rooflights, and edges — Triflex excels. Because it is liquid-applied, it forms a tight, fully bonded waterproof layer around even the most intricate details. For clients, this results in a cleaner finish, stronger performance in vulnerable areas, and fewer long-term maintenance issues.
