For customers searching for heavy duty shed roofing felt, polyester shed felt, long-lasting shed roofing felt or premium green mineral roofing felt, this product provides an excellent combination of strength, durability and value.
Attractive Green Mineral Finish
The exposed surface is finished with a traditional green mineral slate coating, providing both a durable external surface and an attractive appearance.
Green mineral roofing felt is especially popular for garden buildings because it blends naturally with outdoor surroundings and gives sheds, summerhouses and cabins a smart, traditional finish.
20m x 1m Roll for Larger Roofing Projects
With a full 20m x 1m roll, this roofing felt provides approximately 20 square metres of material before allowing for overlaps.
The larger roll size makes it particularly useful for:
- Larger garden sheds
- Double sheds
- Long timber buildings
- Workshops
- Large summerhouses
- Garages

Using a longer roll can also help reduce the number of joints and separate pieces required across larger roof areas.
Single-Layer Waterproof Roofing System
This premium polyester shed felt is designed to be used as a single-layer waterproof roof covering, making it a practical solution for garden buildings where a strong yet straightforward roofing system is required.
When installed correctly, the felt creates a dependable waterproof barrier that helps protect the timber roof deck and the contents of the building from rain and changing weather conditions.
Shed Roofing Felt Installation
For a secure and long-lasting installation:
- Ensure the roof deck is clean, dry and in good condition
- Position the roofing felt flat across the roof surface
- Secure using galvanised clout nails approximately every 50mm
- Apply suitable roofing felt adhesive along the edges and overlaps
- Allow appropriate overlaps between adjoining sections
- Do not remove the film backing from the underside of the roofing felt
Correct installation will help maximise the lifespan and waterproof performance of the finished roof.
Ideal for Re-Felting Larger Shed Roofs
If an existing shed roof has become cracked, torn, leaking or badly weathered, this 20m polyester shed roofing felt provides an excellent replacement option.
Its larger roll size is particularly useful when re-felting bigger sheds, workshops, garages or garden offices, while its polyester construction provides greater strength and durability than many basic shed felts.
When correctly installed, this roofing felt has an expected lifespan of approximately 15 years, making it a strong long-term choice for garden building roof protection.
