Flat roof life expectancy in Hucknall comes down to detailing at upstands, outlets and abutments, not the membrane alone. With typical East Midlands rainfall with strong gusts from the west that lift loose ridge tiles and chimney cowls, those details are where leaks start. We've replaced flat roofs across Bulwell, Bestwood Village, Linby and every quote includes a written specification.
