Shed Roof Repair: Cost & Options 2026 (UK)
A shed roof repair costs £80–£400 in 2026 for a patch or a re-felt, and £250–£700 to replace the covering completely, depending on the shed size and material. The cheapest fix is not always the best value: traditional felt is inexpensive but short-lived, while EPDM rubber costs more up front and lasts decades. Here is what each option costs, when to repair versus replace, and how to get a shed roof that stays watertight.

Felt vs EPDM vs bitumen sheet
Roofing felt is the cheapest and simplest, but even good torch-on felt only lasts 5–10 years and shed-grade nailed felt often less. Bitumen sheets or shingles look tidier and last longer. EPDM rubber is a single seamless membrane with no laps to fail; it costs the most up front but lasts 20–30 years and is now the go-to for anyone who wants to do the job once. For a shed you use as a workshop or garden room, EPDM is usually the best value over time.
Repair or replace?
Patch a small, isolated leak if the rest of the covering is sound and the boards underneath are dry. If the felt is brittle and cracked across the whole roof, or you can see daylight or damp boards, re-covering is the sensible call — repeated patches on failing felt are money down the drain. Always check the deck: soft or rotten boards must be replaced before any new covering goes on.
What a lasting job includes
- Sound deck: rotten boards replaced, surface dry and clean.
- Proper laps or a seamless membrane with well-formed edges and drips.
- Secure edge trims so wind cannot lift the covering.
- Clear water run-off to a gutter or drip edge, not pooling on the deck.
