How Much Does a Garage Roof Repair Cost in 2026? (UK)
A garage roof repair in 2026 typically costs £300–£1,500, while a full garage roof replacement runs £1,200–£4,500 depending on size, material and access. A small felt patch might be £150–£350; a complete EPDM rubber flat roof on a single garage is around £1,500–£2,800. If your garage roof is asbestos cement, do not disturb it — it needs a licensed contractor and safe removal.
How much does a garage roof repair cost in 2026?
Typical 2026 UK garage roof costs:
- Minor felt patch / repair — £150–£400
- Larger repair or re-felt — £400–£1,500
- Full flat roof replacement (EPDM/felt) — £1,200–£3,500
- Pitched garage roof re-tile / re-slate — £2,500–£6,000
Most homeowners with a leaking single garage spend £1,500–£2,800 on a new EPDM rubber flat roof, which typically lasts 20–30 years. Asbestos-cement roofs must be handled by a licensed contractor — never break or drill them.
Garage Roof Cost by Job Type & Material
A single garage roof is roughly 12–18 m²; a double garage 24–36 m². The right option depends on whether the roof is flat or pitched, its current material, and whether a patch will genuinely hold.
Minor repair — patch, reseal, flashing
Fixing a small felt tear, resealing around a flashing or upstand, or clearing and repointing where water is getting in. Fine as a short-term fix if the deck underneath is sound.
Felt flat roof replacement — torch-on / built-up felt
Stripping the old covering and laying new three-layer torch-on felt with a new timber deck if needed. A budget-friendly replacement lasting 10–15 years.
EPDM rubber flat roof — the popular upgrade
A single-piece EPDM rubber membrane with new deck and trims. Seamless, low-maintenance and typically guaranteed 20 years with a 30-year+ service life. The most recommended option for a flat garage roof.
Pitched garage roof re-tile / re-slate
Re-covering a pitched garage roof with concrete tiles or slate, new battens and breathable membrane. More costly but longest-lasting where the garage has a pitched roof.
What Actually Drives Your Bill
Two identical-looking garages can differ by £1,000+. These are the factors that move the price.
1. Repair vs replace
A patch is cheap but temporary. If the deck is rotten or the covering is past its life, a full replacement is better value than repeated repairs.
2. Material choice
Felt is cheapest, EPDM rubber is the mid-range favourite, and GRP fibreglass or tiles cost more but last longer. Material can swing the price by £800+.
3. Asbestos cement
Older garages (pre-2000) often have corrugated asbestos-cement sheets. Safe removal by a licensed contractor adds £500–£1,500+ and must never be DIY-disturbed.
4. Deck condition
If water has rotted the timber deck, replacing it adds £250–£500. It's a common hidden cost only found once the old covering is stripped.
5. Access & scaffold
A detached single garage is easy access; an integral or first-floor garage may need scaffold or a tower, adding £250–£600.
6. Size & region
A double garage roughly doubles material and labour, and London/South East rates run 25–40% above the UK average.
