Roofing Felt | Roofing Sheets
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.
Benefits of Roofing Felt
- Waterproof Protection – Creates a durable barrier against rain, snow, and moisture
- Cost-Effective – Offers a budget-friendly roofing solution without compromising durability
- Thermal Stability – Modified bitumen options (like SBS) resist cracking in cold and softening in heat
- Versatility – Suitable for both new builds and refurbishments across various roof types
- Ease of Installation – Torch-on and self-adhesive variants allow quick, secure application. It is easy to install.
- UV & Weather Resistance – Mineral finish felts protect against sunlight and wear.
Applications of Roofing Felt
- Flat Roofing Systems – Commonly used in three-layer systems with underlay and cap sheet
- Shed & Outbuilding Roofs – Simple, quick fix to keep rain out of smaller buildings
- Garage Roofs – Ideal for protecting low-slope garage roofs from the elements
- Extensions & Porches – Affordable waterproofing for home additions
- Temporary Roof Covering – Offers emergency protection during repair work
Choosing the Right Roof Shed Felt
When selecting roofing felt, consider the following:
- Roof Type: Ensure the product is suitable for the specific type and shape of your roof.
- Durability Needs: Look for higher-grade materials if the roof will be exposed to harsh weather conditions.
- Installation Method: Choose between torch-on, self-adhesive, or other types based on your installation preference and skill level.
