Stopping leaks where roofs meet walls, chimneys and dormers – new lead flashings, valleys and soakers, plus fascias, soffits and gutters.

Most roof leaks are not caused by slates or tiles but by the joints – where a roof meets a chimney, a wall, a dormer or another roof slope. These joints are usually sealed with lead, which lasts a long time when properly sized and fixed, but fails when the lead is too thin, too long, or held in with sealant instead of being dressed into the joints.
We use the right thickness of lead for each detail, keep individual pieces short enough to cope with expansion, wedge and point them into joints, and avoid relying on mastic sealant.
