Flashing Repairs in Portsmouth

Portsmouth customers looking for flashing repairs turn to Hampshire Roof Repairs. Flashing is the material — traditionally lead, though alternatives exist — used to seal the junctions on a roof where two different surfaces meet: a chimney meeting the tiles, a roof meeting a wall, around a dormer window, or at the edge of a roof-light. These junctions can't be sealed with tiles or slates alone because the materials and the angles involved are too different, so flashing bridges the gap and is dressed to shed water away from the joint. It's also one of the more failure-prone parts of a roof, because it has to accommodate genuine thermal movement — expanding and contracting with temperature — as well as wind, and can be dislodged by anything from a heavy gust to nesting birds working under the edge. A lifted or split section of flashing is a very common, very fixable cause of a leak that otherwise looks mysterious, because the tiles either side of it can look completely undamaged. Portsmouth's densely packed terraces sit on an island surrounded by water on almost every side, and that constant salt-laden exposure accelerates corrosion on lead flashing and metal fixings noticeably faster than an equivalent inland roof. Shared party walls between terraces mean a chimney or valley problem can affect the junction between two neighbouring properties, and the tight streets typical of Portsea Island mean access for repair work often needs planning around on-street parking rather than a driveway.
