Roofing Felt | Roofing Supplies

Protect your roof with durable, weather-resistant roofing felt from JJ Building Materials. Whether you’re working on a shed, garage, extension or a full roofing project, our range includes high-performance options designed to provide long-lasting waterproofing, insulation and protection. With choices such as Torch On Felt, Shed Felt, Breathable Felts, Vapour Control Layer, and Eaves Protection, you can build a roof that is secure, efficient and built to withstand harsh UK weather.

Torch On Felt for Professional, Long-Lasting Protection

Our Torch On Felt range offers exceptional strength and waterproof performance. Ideal for flat roofs, garages and commercial projects, these membranes are applied using a heat-bonded method that ensures a strong, durable seal. Torch On Felt is engineered to resist UV exposure, standing water and temperature changes, making it a reliable solution for long-term flat roof protection.

Shed Felt for Quick and Reliable Roofing

For garden buildings and smaller structures, Shed Felt provides an easy-to-install waterproof layer that protects against rain, wind and everyday wear. Its lightweight design makes installation simple, while its protective mineral surface helps prolong the life of your shed or outdoor structure. Shed Felt is perfect for DIY users and maintenance jobs.

Breathable Felts for Ventilated Roof Structures

Our Breathable Felts support airflow within pitched roof systems, helping reduce condensation and improve energy efficiency. These felts allow moisture to escape from within the building while keeping external water out, providing essential protection for modern warm and cold roof constructions.

Vapour Control Layer for Moisture Management

A Vapour Control Layer is vital for preventing condensation build-up inside your roof space. Installed on the warm side of insulation, these membranes reduce the movement of water vapour and help maintain the performance of insulation materials. Essential for new builds and refurbishments, a Vapour Control Layer enhances the longevity of your entire roof structure.

Eaves Protection for Extended Roof Lifespan

Our Eaves Protection products defend the lower edge of your roof from water ingress and rot. Designed to sit beneath the felt, these rigid trays support the roofing membrane and ensure rainwater drains correctly into the gutter. Using Eaves Protection helps prevent sagging felt and long-term moisture damage.
