Lead Flashing Repairs

Lead flashing seals the junctions between your roof and vertical surfaces — chimneys, walls, dormers, and valleys. When flashing fails, water enters these critical joints and causes internal damage that's often hidden until it's extensive.

Flashing fails for several reasons: thermal expansion cracks the lead, mortar chases deteriorate, or the original installation was poor. We assess the flashing, determine whether repair or replacement is needed, and carry out the work to last.

We use Code 4 and Code 5 lead, properly dressed and fixed into chases with appropriate sealant. Our flashing work is designed to accommodate thermal movement without cracking — a common cause of premature failure.

Why does lead flashing crack?

Thermal expansion. Lead expands and contracts with temperature changes. If pieces are too long or not properly dressed, they crack at stress points. Proper installation accounts for this movement.

Can flashing be repaired or does it need replacing?

Minor cracks can be repaired with sealant or lead patches. If the lead is heavily fatigued, cracked in multiple places, or poorly installed, replacement is the better long-term solution.

How long should lead flashing last?

Properly installed Code 4 or Code 5 lead flashing should last 50-100 years. Premature failure usually indicates installation issues.
