Garage Roof Replacement Cost in the UK

Garage roofs — particularly flat ones — are often the first part of a property to need replacement. Whether you've got a leaking felt roof or a deteriorating pitched garage roof, here's what to expect in terms of costs.

Garage Roof Cost by Type

Garage Type	Felt	EPDM Rubber	GRP Fibreglass
Single Garage (15 m²)	£800 – £1,200	£1,200 – £1,800	£1,400 – £2,000
Double Garage (30 m²)	£1,200 – £2,000	£2,000 – £3,000	£2,500 – £3,500
Pitched Garage (tiles)	N/A	N/A	£2,000 – £4,000

Flat vs Pitched Garage Roofs

Most UK garages have flat roofs, which are simpler and cheaper to replace. If your garage has a pitched (tiled) roof, costs are higher due to the additional materials and labour involved.

• Flat garage roof: £800–£3,500 depending on material and size
• Pitched garage roof: £2,000–£4,000+ including tiles, battens, and felt

What's Included in the Cost?

• Stripping the old roof covering
• Inspecting and repairing timber decking (if needed)
• New roofing material installation
• Edge trims and drip details
• Waste disposal
• Any necessary fascia or soffit repairs

Is It Worth Replacing a Garage Roof?

If you use your garage for storage or as a workshop, a waterproof roof is essential to protect your belongings. Even if the garage itself isn't valuable, a leaking roof can cause damp problems that spread to the main house if the garage is attached.
