Leadwork in Chesham and across Buckinghamshire
A lot of roof leaks don’t come from the tiles themselves — they come from the joins. Where the roof meets a chimney, a wall, a valley, or an extension, you’re relying on the waterproof detailing to do its job. That’s where leadwork matters. When lead flashing splits, lifts, or has been fitted poorly in the first place, water will find a way in. Often you’ll only notice it once a stain appears indoors, or after a spell of driving rain.
At Southeast Roofing & Building, we carry out leadwork in Chesham and complete lead roofing work across Buckinghamshire, including repairs and new installations. We’ve got 10 years’ experience, we’re fully insured, and all work is guaranteed. We’re also proud of the reputation we’ve built through genuine reviews on Checkatrade, TrustATrader and Google — largely because we focus on doing the awkward details properly, not just the obvious bits.
Our leadwork service in Chesham
Lead is used on roofs for a reason: it’s durable, flexible, and perfect for weatherproofing junctions. But it needs to be installed correctly to perform long-term. The most common issues we see are lead that’s been cut too short, fixed incorrectly, or has fatigued over time due to movement and temperature changes.
What our leadwork includes
Our roof leadwork services typically cover
Lead flashing repair around chimneys, dormers and wall abutments
Replacement lead flashings where sections are split, lifted or beyond repair
Soaker flashings (individual stepped sections) for brick walls and side abutments
Apron flashing at the front of chimneys and stepped flashings to the sides
Back gutter work behind chimneys where water collects and needs directing away
Valley leadwork repairs and replacements where valleys have failed or overflow
New gutter installation for extensions, garages and new roofline set-ups
Lead detailing on flat roof upstands and roof junctions
Re-securing and making good where chase lines have opened up in the brickwork
If we find the leak is coming from elsewhere — a cracked tile, ridge issue, damaged felt, or blocked guttering — we’ll tell you straight away. The aim is always to fix the true cause, not just “do some leadwork” and hope it solves it.
How we deliver the work
We inspect the area properly and look for the usual failure points: split lead, lifted edges, failed pointing in the chase, poor overlaps, or signs of water tracking underneath. Then we’ll explain what needs doing in plain English and carry out the repair or replacement using the right method for that detail.
Good leadwork is all about neat finishing and correct fixing. We take our time with it because it’s the difference between a roof that stays dry and one that keeps letting water in every winter.

Frequently Asked Question
What are the signs that lead flashing has failed?
Common signs include damp patches around chimney breasts, staining on upstairs ceilings near external walls, leaks that worsen in wind-driven rain, and visible lifting or cracking on the lead itself.
Can you repair lead flashing, or does it always need replacing?
It depends on the condition. Small issues can often be resolved with a lead flashing repair. If the lead is split, fatigued, or poorly installed, replacement is usually the better long-term option.
Why does leadwork fail in the first place?
Movement, temperature changes, poor fixing, incorrect overlap, or pointing failures in the chase line can all cause issues over time — especially in exposed areas.
Do you do leadwork as part of chimney and roof repairs?
Yes. Leadwork is often part of a wider repair, especially around chimneys, valleys and roof junctions. We’ll advise on what’s needed based on the roof’s condition.
Is your leadwork guaranteed and insured?
Yes — we’re fully insured and all work is guaranteed.
