How long will a flat roof in Arnold last?
A correctly installed EPDM or GRP flat roof on a Arnold extension should comfortably last 20–25 years. Torch-on felt is shorter-lived but still gives strong value across NG5 when specified well.

Nottinghamshire · NG5
Flat roofs on Arnold properties take a beating — mild urban climate but heavy summer downpours that overwhelm undersized 1930s cast-iron gutters. Whether it's a single-storey kitchen extension, a garage roof or a dormer cheek, we install EPDM rubber, GRP fibreglass and torch-on felt systems across a large suburban town on the north side of Nottingham, with interwar semis around Arnot Hill Park, postwar housing along Front Street and modern detached homes pushing toward Daybrook and Killisick. Every job is specified for that particular roof rather than fitted off a generic price list.
