What the job involves
Flat roof replacement is priced per square metre of covering, with the system choice (EPDM, GRP, felt, TPO) driving most of the variance. A typical small extension is 15–25 m², which puts full replacement in the £1,200–£4,500 range before scaffold and skip.
A proper replacement includes checking and usually replacing the deck underneath, creating sufficient falls to avoid ponding, and dressing upstands properly into the abutting wall or parapet. Cheap quotes often skip these details.
Sunderland — local context
