Leadwork Specialists Across Kent
Lead is the traditional, long-lasting material for weathering the junctions and details on a roof — around chimneys, in valleys, at abutments and in parapet gutters. Pro Guard Roofing Specialists Ltd carries out specialist leadwork across Kent, from renewing perished flashing to forming new lead valleys and gutters, dressed and welded to a weathertight standard that lasts for decades.
About this service
Leadwork is the skilled craft of forming lead sheet into the flashings, valleys, soakers and gutters that keep a roof weathertight at its most vulnerable points. Correctly dressed and welded lead is extremely durable — a well-formed lead flashing or valley can outlast the tiles around it. Poorly fitted lead, or the wrong thickness, fails early and lets water in.
We use the correct code (thickness) of lead for each application, allow for thermal movement so the lead does not split, and dress and weld joints to a traditional, weathertight standard. Common leadwork includes chimney back gutters, step and cover flashings, valley gutters, soakers under slates, and lead-lined parapet or box gutters.

Frequently asked questions
How long does lead flashing last?
Correctly installed lead flashing of the right code, with movement allowed for, can last 50 years or more. Premature failure is usually down to the wrong thickness or poor dressing, which is why specialist leadwork matters.
Why has my lead flashing cracked?
Lead expands and contracts with temperature. If it is fixed without allowing for that movement, or the wrong thickness is used, it work-hardens and splits. We replace it with the correct code and detailing.
Do you form new lead valleys?
Yes. We form and line new lead valleys and gutters, and renew failed ones, using the correct lead code and undercloak detailing so water is carried safely away.
Can you match existing leadwork on a period property?
Yes. We work on period and listed properties and use traditional lead detailing appropriate to the age and style of the building.
Why is water coming in around my chimney?
Water entering around a chimney is most often caused by failed lead flashing — the step or cover flashing that seals the join between the stack and the roof. Cracked flaunching and weathered mortar are other causes. We inspect the chimney, trace the true entry point, and repair it properly. See our chimney repairs page for more.
My lead flashing is leaking during heavy rain — can you help?
Yes. Cracked or split lead flashing is a common cause of winter leaks around chimneys, valleys and abutments. We inspect the leadwork — using a drone where helpful — and renew it with the correct lead code and detailing so the repair lasts. See our roof leak repairs page if you are tracing a leak.
