Flat roofs on Mansfield properties take a beating — a mix of wind-driven rain off the Pennines and sharp frosts that crack older mortar joints and clay ridge tiles. 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 the largest town in the Nottinghamshire coalfield, with Victorian terraces around the town centre giving way to large interwar semis in Berry Hill and newer estates around Forest Town. Every job is specified for that particular roof rather than fitted off a generic price list.
