    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.
