Chimneys and the lead around them are where roofs leak first. We repair, repoint and reflash chimneys across Hampshire, renew lead valleys and flashing, and waterproof every joint where the roof meets a wall.
A chimney breaks up the run of a roof, and every joint around it relies on lead and mortar. When those fail, they cause problems of their own.
The lead flashing sealing the chimney to the roof splits and lifts over time, so rain runs straight down beside the brickwork.
Cracked and missing mortar on a chimney lets water into the joints, where it soaks the stack and the roof below.
The lead in valleys and around penetrations fatigues and splits, and each split is a direct route into the roof.
Left alone, water tracks in around the chimney and shows up as damp and staining on the breast and ceilings inside.
Sealing the chimney, the valleys and the joints properly is what keeps water out at the very points a roof is most likely to fail.
Repair damaged stacks and repoint failing mortar to keep the chimney sound and weathertight.
Safely remove an unused chimney and make the roof good where it stood.
Repair or renew the flashing that seals the chimney and roof joints against water.
Repair and replace worn lead valleys before splits let water into the roof.
Renew tired or damaged leadwork to a lasting, weathertight standard.
Fit chimney cowls, seal around roof penetrations and waterproof where the roof meets walls.
Chimney and lead work is not a single fix. Several joints work together. Here is how the survey, the lead and the finish fit into the six steps.
We inspect the chimney, flashing and leadwork, find the cause of the leak and advise honestly on what needs doing.
You get clear written costs covering the leadwork, mortar and any related work, with no hidden extras.
We remove the cracked flashing, worn lead or failing mortar around the affected area.
We repoint the stack and make good any brickwork or roof disturbed by the leak.
We dress in new lead flashing, valleys and seals so water runs off, not in.
We check the joints are watertight, then leave your property clean and tidy.
