Waterproofing and Flashing
Roof junctions, chimneys, and valleys are the most common entry points for rainwater. We install and repair lead flashing and waterproof membranes to seal these vulnerable areas completely.
When You Need Waterproofing
Cracked, loose, or missing mortar and lead flashing around brickwork. Damp patches appearing on walls right below roof intersections. Aging sealants breaking down around roof penetrations and skylights.
How We Do It
We remove old, cracked mortar and damaged leadwork cleanly. We install fresh lead flashing and weatherproofing seals tailored to the joint. We check the seal integrity to ensure complete protection against driven rain.
What to Expect
Flashing repairs and waterproofing updates are typically completed within a single day.

Waterproofing and Flashing FAQs
Flashing is thin metal, usually lead, installed at joints and roof penetrations to divert water away from seams.
Constant exposure to weather causes thermal expansion and contraction, which eventually loosens mortar and cracks joints.
Minor gaps can be repointed, but severely damaged or split lead flashing is replaced for lasting security.
Proper flashing and waterproofing eliminate the vast majority of residential roof leaks caused by heavy rain.
