Each roll measures 10 metres long by 1 metre wide, providing approximately 10 square metres of roofing material before overlaps.
This convenient size makes it suitable for many standard garden buildings, including:
- Garden sheds
- Summerhouses
- Small workshops

- Timber storage buildings
- Garden structures
The 1m width also makes the felt relatively easy to position and handle during installation.
Single-Layer Waterproof Roof Covering
This roofing felt is designed for use as a single-layer waterproof top coat, making it a straightforward solution for many shed and garden building roofs.
When correctly fitted, the felt creates a weather-resistant barrier over the timber roof deck, helping protect the structure and contents from rain and everyday weather exposure.
Shed Roofing Felt Installation
For a secure installation:
- Ensure the roof deck is clean, dry and in good condition
- Position the roofing felt smoothly over the roof
- Secure using galvanised clout nails spaced approximately every 50mm
- Apply suitable felt adhesive or felt joint adhesive along edges and overlaps
- Allow sufficient overlap between adjoining sections
- Seal edges and joints carefully to help prevent water ingress
- Do not remove the film backing
Correct installation is important for achieving the best waterproofing performance and maximising the expected lifespan of the roofing felt.
Designed to Stay Flat
One of the useful features of this glass fibre roofing felt is its ability to stay flat after installation.
This makes the felt easier to work with and helps reduce creasing or rippling across the completed roof surface.
For DIY users in particular, this can make it easier to achieve a tidy and professional-looking finish.
Ideal for New Roofs & Replacement Projects
Whether you’re constructing a new garden building or replacing worn existing felt, this charcoal mineral shed roofing felt provides a simple and economical roofing solution.
It is particularly suitable for customers who want dependable weather protection without moving to a heavier polyester or SBS premium roofing system.
