New flat roofs, replacements and repairs, done properly

As a guide, re-covering an 18 m² single garage roof costs around £1,500–£2,600 in torch-on felt or £1,600–£2,800 in EPDM, including VAT. A 20 m² extension roof with a new deck and warm-roof insulation is around £2,800–£4,900 in EPDM. These are guide prices, and the fixed price comes after the free survey.

A localised patch repair is typically £150–£500, and an upstand, flashing or abutment repair £250–£650. An emergency temporary-weatherproofing visit is around £180–£450, and the fixed price for any permanent repair is confirmed once the roof has been inspected.

No single system is best for every roof. EPDM suits simple roofs and has a long life, GRP suits roofs with complex details or occasional foot traffic, and modern torch-on felt is robust and good value. With good specification and maintenance, indicative lives are 25–50 years for EPDM, 20–40 for GRP and 15–25 for torch-on felt.

A flat roof typically lasts anywhere from 10 to 60 years, depending on the system: torch-on felt 15–25, liquid-applied 10–25+, GRP 20–40, single-ply 25–35+, EPDM 25–50 and mastic asphalt 30–60. Good falls, careful detailing and regular maintenance matter as much as the material.

Usually not, if the roof's appearance does not change materially. Listed buildings need listed building consent for changes that affect their character, some conservation areas have Article 4 directions, and a new roof terrace or balcony generally needs planning permission.

Often, yes. In England, Wales and Northern Ireland, re-covering a flat roof over heated rooms is usually renovation of a thermal element, and if more than half the roof is renovated the insulation should be upgraded where feasible, which normally needs approval. We handle building control where it is needed.

A typical garage or extension roof usually takes one to four days, depending on its size, the condition of the deck and the weather. Larger and commercial roofs take longer and are planned in phases.

The team only strips as much roof as can be made watertight before leaving site, and keeps temporary covers ready. GRP and liquid systems need dry conditions and suitable temperatures to cure, so work may be moved to a better day.
