Leadwork in Hertfordshire: flashings, valleys and chimney lead that keep the water out

Leadwork in Hertfordshire for split flashings, worn valleys and lifting chimney lead, renewed to keep the water out. Ring Kieran on 07310 120341 or send the form for a free written quote.

Lead seals every junction on a roof: where the tiles meet a wall, round the base of a chimney, down the valleys and across bay tops and dormer cheeks. Fitted right, it lasts for decades. Fitted badly, or in lengths that are too long, it splits as it heats and cools, and the water goes straight in.

We renew step flashings and soakers on abutments, aprons and back gutters on chimneys, lead valleys between roof slopes, and the lead on bays, porches and dormers. The old lead comes out, the joints are wedged and pointed, and new lead is dressed to fit.

Storms find weak lead first. Jade's Google review: "Had an issue with my roof flashing after a storm, he was very quick to come out and have a look/quote."

A leak round a chimney or along a wall is a lead leak more often than not. Fix the lead and the damp patch stops.

Leadwork: your questions answered

How much does leadwork cost in Hertfordshire?

Across Hertfordshire, new lead flashing round a chimney runs about £400 to £900, and renewing a lead valley about £600 to £1,500. Length and access set the price, and scaffold adds to it where it is needed. Kieran's free written quote gives you the real figure.

How long does roof lead last?

Properly fitted lead lasts for decades. Early failures come down to lengths that are too long or fixings that are too tight, so the lead cracks as it moves with the heat.

Can you repair lead instead of replacing it?

Small splits and lifted edges can be refixed and sealed. Lead that has cracked along its length or worn thin needs replacing.

Do you fit lead on bays, porches and dormers?

Yes. Dormer cheeks, dormer tops, bay tops and porch roofs are all leadwork we do.

Highly recommend! Had an issue with my roof flashing after a storm, he was very quick to come out and have a look/quote. Work was carried out the following week and a further issue was found after work started, was very generous in supporting me with the added cost!

KlebersonNew roof · September 2026

Outstanding roofing company! I honestly can’t recommend KR & Sons Roofing & Guttering Ltd enough. From the first contact, they were friendly, professional and extremely helpful. The whole team worked incredibly hard and the standard of their workmanship was brilliant. They were reliable, tidy and kept me informed throughout the job, and the finished roof looks absolutely fantastic. It’s not often you come across a company that takes this much pride in their work. I’m extremely happy with the result and would have no hesitation whatsoever in recommending them to family, friends or anyone looking for a top-quality roofing company. Fantastic team, fantastic workmanship and a fantastic service from start to finish!
