Lead on Your Roof

Leadwork Where Roofs Meet

Most leaks on a sound roof start at a junction rather than in the middle of the tiles: where a chimney passes through, where a wall rises above the slope, or where two pitches meet in a valley. Lead keeps those joints dry because it can be shaped by hand to fit almost any profile.

Our team fits new lead flashings, lead valleys, lead-lined gutters, bay and porch roofs and dormer cheeks on homes in Amersham and across the county. On a full re-roof the leadwork is part of the job, and our new roofs page explains how we plan that work.

We follow general good practice for lead: the right code (thickness) for each position, pieces kept to sensible lengths, and expansion joints so the metal can move with the seasons without splitting. That care over detail is what lets lead last as long as it should.

Leadwork: How It Works

How a Leadwork Job Runs

Each roof differs, but most leadwork follows the same broad stages from first look to final check.

1

Inspect the Joints

We look at the existing lead, the mortar and the tiles around it to find where water is getting in and why the old lead failed.

2

Written Quote

You receive a written price listing each piece of lead, its code and the fixing method, along with the days we plan to be on site.

3

Strip & Refit

Old lead and loose mortar come out, the chases are cleaned, and new lead is cut, dressed and fixed with room to expand.

4

Final Check

Once the last piece is pointed in and the offcuts are gone, we review the completed work with you and confirm everything has been done as agreed.

Leadwork FAQs

Leadwork Questions Answered

What Is a Lead Code?

A lead code is a number that describes the thickness and weight of the sheet. Thinner codes are easier to dress into tight shapes, so they suit step flashings, while heavier codes go where lead lies flatter and has to resist wear, such as valleys, gutters and bay roofs. Picking the right code for each position has a big effect on how long leadwork lasts.

Why Has the Lead Around My Chimney Cracked?

Lead expands in summer heat and contracts in winter. If a piece was fitted too long, nailed too tightly or cut from a code that was too thin, that movement eventually splits it. Old pointing that has fallen out of the chase also lets water behind the flashing. We work out which of these caused the problem before pricing the replacement.

Can You Replace Lead Without Re-Roofing?

Usually, yes. Flashings, valleys and bay roofs can normally be replaced on their own, lifting only the tiles or slates next to them and refixing them afterwards. Where the surrounding covering is in poor condition we will tell you, and you decide whether to deal with it now or leave it for another time.

Is Lead Still the Best Material for Flashings?

Lead remains the traditional choice because it is heavy, holds its shape once dressed, and can be formed around brick, stone and tile without joints. Other materials exist, but lead is still what most roofers reach for on period properties and complicated junctions. We will explain the options on your roof and let you choose.

Why Do Lead Valleys Leak?

A valley carries the rain from two slopes, so it handles more water than any other part of the roof. Leaks tend to come from splits where long lengths were laid without laps, from leaves building up and pushing water over the edge, or from lead that was too thin for the position. Renewing valley lead normally means lifting the tiles along each side.

Do You Fit Lead to Bay Windows & Porches?

Yes. Small flat or curved roofs over bays and porches are often covered in lead, dressed over timber boards and joined with rolls or welts so the sheets can move. We can strip a tired covering, check the boarding beneath and lay new lead that suits the age and style of the house.
