If you’re looking for a durable, cost-effective, and long-lasting solution for your flat roof, the 3-layer torch-on felt roofing system is hard to beat. At Marlow Roofing Company, we specialise in fitting high-quality felt roofs for garages, extensions, dormers, and more – with all work fully guaranteed.
What Is a 3-Layer Torch-On Felt Roof?
This modern system is made up of three key layers of bitumen-based felt, each heat-bonded to form a seamless, watertight finish. It’s installed using a gas torch, which melts the layers together, making the system strong, weatherproof, and built to last.
How the 3-Layer System Is Installed
- Roof Preparation
We start by removing any old materials and repairing damaged decking. The surface is cleaned and primed to ensure perfect adhesion. - Base Layer – Venting Sheet
This bottom layer allows any moisture to escape from below, reducing the risk of trapped condensation and blistering. - Underlay – Reinforced Felt
A middle layer of tough, reinforced felt adds durability and acts as an extra waterproof barrier. - Cap Sheet – Mineral Finish
The final top layer has a UV-resistant mineral surface, providing protection from sun, rain, and daily wear and tear. - Edge Sealing & Trims
All seams, edges, and corners are sealed and detailed for a professional, watertight finish. Trims and drip edges ensure water flows away cleanly.
