Welcome to the Roofing Felt category on Build4Less, where you will find a comprehensive range of roofing felt products suited for various applications and projects. Roofing felt is an essential material in the construction and repair of roofs, providing an extra layer of protection against the elements. Here, we explore the different types of roofing felt available, their practical uses, and guidance on selecting the appropriate type for your needs.

What is Roofing Felt?

Roofing felt is a flexible, waterproof material used beneath roofing materials or as a standalone layer to protect roofs from water ingress, wind damage, and UV rays. It is typically made from bitumen-saturated base materials like polyester or fibreglass and can be torch-on, self-adhesive, or nail-on. Roofing felt is especially popular for flat roofs, sheds, garages, and extensions.

Types of Roofing Felt

Torch-On Roof Felt

Our collection includes various Torch-On felts like the Danosa and FIX-R SBS Underlays and Cap Sheets. These are typically used in flat roofing and require a torch to melt the bitumen, allowing it to bond securely to the roof surface. Polyester-reinforced Torch-On felts are popular for their durability and effective waterproofing qualities.

Cap Sheets and Underlays

Cap Sheets, such as the FIX-R Classic and IKO Britorch Non-Woven varieties, provide the top layer of protection, offering additional UV resistance and waterproofing. Underlays, including the universal types from FIX-R and IKO, are used beneath the cap sheet to provide an extra layer of waterproofing and insulation.

Specialty Roofing Felts

We also offer specialised products like the IKO Adesso and Polyester Torch-On Cap Sheets, designed for specific applications such as higher durability or adaptability to various roof types. These products are perfect for when a custom or enhanced solution is required.
