Roof
Heavy-Duty Mineral Felt
The standard roof covering on every timber building.
Why we build with this
Mineral felt is the covering every installer knows and every customer can maintain, which is exactly why it's our standard. It's proven, easily patched or replaced, and it keeps the price of a good timber building down. Anyone who wants a seamless, longer-life roof can upgrade to EPDM in a couple of clicks.
Dimensions
40kg green mineral felt, nailed and lapped
Every timber building comes with heavy-duty mineral felt as standard — nailed and lapped in the traditional way. It's a well-understood, easily repaired covering; anyone wanting the single-membrane EPDM upgrade can add it in the Build Studio.
Benefits
- Included as standard on every timber building, no extra cost
- A proven, familiar roofing method any installer can work with
- Straightforward to repair or replace in future
Worth knowing
- Nailed, lapped seams are a possible weak point over time
- A shorter expected lifespan than an EPDM rubber roof
- Can be upgraded to EPDM rubber at build time
