Lead Flashing Repairs in Stockport
Lead flashing has to shed rain while still being free to expand and contract. Problems often start where long pieces have been fixed too rigidly or folded sharply.
Look at stress points first
Corners, folds and the ends of long lengths are common places for splits.
The chase above the lead matters
Even sound flashing can leak if the mortar joint holding its upper edge has opened and lets water behind it.
Several layers of sealant can hide the original defect
Bitumen or sealant can slow a leak for a while, but several old coats often hide split lead and make a proper repair harder.
