Leadwork and flashing around a chimney

Leadwork & Flashing Repairs in Somerset, Bristol, Bath & Devon

Flashing and leadwork seal the joints where a roof meets chimneys, walls and valleys — and when they fail, water gets in. Cracked, lifted or poorly-fitted lead is one of the most common causes of roof leaks, and one we put right regularly.

1 year workmanship guarantee — Roof repairs and maintenance work, subject to the agreed scope of the repair.

What's included

When you compare quotes, check what's actually in them. Ours include the things that determine whether the job lasts:

  • Inspection of the flashing and surrounding detail
  • Replacement or re-dressing of failed leadwork
  • Re-pointing and re-sealing where needed
  • Checks of nearby junctions for related issues
  • Tidy finish matched to the roof

How we approach it

Step 1

Inspect

We check the flashing, the mortar, and the surrounding tiles or slates to find where water is getting past.

Step 2

Repair

Failed lead is replaced or re-dressed, joints re-pointed and sealed, and fixings made good.

Step 3

Verify

We check related junctions so the same leak doesn't reappear from a neighbouring detail.

Ideal for

  • Chimney flashings and back gutters
  • Wall abutments and step flashings
  • Valleys between roof slopes
  • Any lead detail showing cracks or lifting

Options & finishes

  • Localised flashing repair
  • Full re-lead of a chimney or valley
  • Combined with chimney repointing where needed

Important considerations

  • Very old lead can be brittle; sometimes replacement is more sensible than repeated repair.
  • Chimney structural work (rebuilds) is outside our standard remit, but we can advise.
  • Carries a 12-month workmanship guarantee, subject to terms.

Leadwork & Flashing — your questions answered

Why does flashing fail?

Lead expands and contracts with temperature; over decades this can crack it, and wind can lift poorly-fixed lengths. Mortar pointing around it also weathers and fails. All of these let water in and are repairable.

Is my chimney leak the flashing?

Very often, yes — chimney junctions are one of the most common leak points on a roof. We'll confirm whether it's the flashing, the pointing, or something else before repairing.

Do you re-lead whole valleys?

Yes — where a valley's lead has failed, we can replace the full run rather than patch it, which is usually the lasting fix.
