Leadwork and lead flashing
Most roof leaks aren't holes in the roof. They're failures where the roof meets something else: a chimney, a wall, a valley, a bay. Those junctions are what lead is for, and lead done properly outlasts almost everything around it.
Done badly, or replaced with cement because it was quicker, those same junctions become the thing that ruins the ceiling below.

What we do
- Chimney flashings,
- including stepped flashing, back gutters and soakers
- Valleys,
- both open lead valleys and secret gutters
- Abutment flashings
- where a roof meets a wall, as on extensions and dormers
- Box gutters and parapet gutters,
- common on the terraces round here
- Bay window roofs,
- which on Victorian property are frequently lead
- Dormer cheeks and tops
- Soakers and cover flashings
- on any junction
- Lead slates
- around pipes and vents
Why cement isn't a substitute
Walk round any terraced street locally and you'll see chimneys with a wedge of cement where the flashing should be. It's quick, it's cheap, and it fails.
Cement is rigid. Lead moves, and a roof moves constantly with temperature. A cement fillet cracks within a few years, then holds water in the crack rather than shedding it, which is worse than nothing at all. Once it's cracked, water runs behind it and straight down the chimney breast.
If you've got damp on a chimney breast, a cracked cement fillet is the most likely cause on this housing stock.
Doing lead properly
Lead is specified by code, from Code 3 up to Code 8, which is simply how thick the sheet is. Heavier code goes where there's more exposure or more movement.
Two rules matter more than anything else, and both get broken constantly.
- Lead has to be allowed to move.
- Individual pieces have maximum lengths for exactly this reason. One long continuous run instead of properly lapped shorter pieces will split, because lead expands and contracts and something has to give.
- It has to be fixed and dressed, not stuck.
- Wedged into a raked joint, pointed, and dressed to shape with the right tools. Mastic holding lead in place means it was fitted by somebody in a hurry.
Signs your leadwork has failed
- Damp on a chimney breast, particularly after driving rain
- Staining down an internal wall where an extension meets the house
- Visible cracks in cement fillets around a chimney or abutment
- Lead that's lifted, rippled, or split along its length
- Water in the room below a bay window
- Green or white staining on a wall beneath a flashing
The things people ask us
Longer than most roofs. Properly fitted lead on a chimney will outlive the covering around it, which is why it's worth doing once rather than three times in cement.
Splits can sometimes be lead-welded, and a lifted flashing can be re-dressed and re-fixed. If it's split because it was one long piece with nowhere to move, it needs replacing correctly or it'll do exactly the same thing again.
Surface oxidation, and it's normal. It's the lead protecting itself. It's not a fault and it doesn't need cleaning off.
Realistically yes. Anyone proposing to re-flash a stack off a ladder is taking a risk with their own safety and with the quality of the work, because you can't dress lead properly one-handed.

Alex did our roof when it needed some repair. Was great, advised what was needed once he was up there (and could see the state of things) and fixed everything up. The roof looks good as new and also spruced up the guttering whilst he was up there. Will definitely use him again if needed in the future.
Alec did an excellent job on my roof I would recommend him to anyone wanting a good workman at a competive price
Alex replaced my guttering, did an excellent job, no mess, reasonable price, would highly recommend.
Alex did a brilliant job, explained everything, very reliable, left no mess, would definitely use him again and would recommend to anyone.
Alex did a fantastic job at a very reasonable price. Honest and trustworthy from the first minute he came to look at my roof, was the only roofer who took the time out to actually go up on the roof before talking me through what was needed.
Quality work completed at competitive price, turned up and completed work time
We met Alex by chance one rainy afternoon on the local canal towpath. We were both sheltering from the rain under the same bridge. My husband and I had, earlier, been discussing our garage roof which was new a few years ago, but which had been leaking for some time. We think our chance meeting with Alex was meant to happen as, for some reason, I mentioned our leaky roof to him. We have always had difficultly finding reliable…
Excellent job, lovely people, very good roofers and sensible prices
Absolutely brilliant service from start to finish. The work was completed to a really high standard they were reliable, professional and tidy throughout. It’s clear they take pride in their work, and the finished roof looks fantastic. Would definitely recommend them to anyone looking for a trustworthy, hardworking roofer. Thank you to Alex, Jeff, Ryan & Junior Kath & Eric at Number 6
Great job done by Alex, Jason and Alfie on our chimney stack and roof. They provide a very professional friendly, service and are a pleasure to work with. We wouldn’t hesitate to recommend their services. Thank you so much.
Professional job from start to finish. Polite, tidy and cleaned up after themselves. Would highly recommend.
Alex replaced our guttering, reset all the ridge tiles on the roof and capped the chimney properly. Alex and Luke were a breathe of fresh air to deal with. Alex was very friendly, he kept us informed of progress and what they were doing. He attended at the specified time and always kept everything clean and tidy. Quotes were accurate and were stuck to. Quality work throughout so if you want half a job doing don't call him. Personally…
Can’t recommend Alex highly enough , we got in contact on Saturday explaining we had some issues with lead flashing around chimney , leaking gutter etc and he responded straight away and then called Sunday to discuss . Made an appointment for Monday after work where he explained the issue and the cost . Today he came round and sorted all the problems as discussed , Alex is a great guy who you can tell cares about his work and his…
Excellent work done by a superb team. Alex, Geoff and Luke have done an incredible job on my roof and front of house. The roof no longer leaks (when living in Preston that's an important thing!) and the front of the house appearance has been transformed from an old tired look to a clean and more modern feel. They provide great advice, give you a quote detailing what they are going to do and then crack on and do a brilliant job…
Alex and Geoff took great care inspecting the roof and deciding on a plan of action. Geoff and Luke worked seamlessly together to repair the numerous faults they discovered. They were cheerful and courteous at all times and were always ready to explain how the work was progressing and the issues they were dealing with as they arose. Jason and Alfie did a good job with the rendering. Photographs were provided, documenting their…
Alex came to our rescue and quickly repaired my elderly mother's damaged roof. The work was completed within 2 days and we are very happy with the quality of the work provided. Thank you Alex and your team for a fast and friendly service at a reasonable price. What a brilliant job! I can highly recommend Alex and his hard-working team.
We had a leak in the living room, which we didn’t know where it was coming from, but we thought it was the gutter. We called Alex after he was recommended to us, the same week on the Saturday he came and had a look diagnosing where the leak was coming from and giving everywhere a good look, letting us know we also had 3 tiles slipped on the kitchen roof which he’d sort for us too. Two days later the work started and we couldn’t be…
Very pleased indeed. Alex was responsive, helpful and, as chance would have it, was able to do the repair to the guttering at our daughter's bungalow, promptly. The charge was minimal for two tradesmen. Would certainly use again and have no hesitation in recommending him to others.
Alex and Luke have pointed our chimney and replaced pots. All the ridge tiles have been removed and replaced. Nothing has been too much trouble for these guys. We are more than happy with the end result. Totally reliable and trustworthy. Very friendly lads. I would 100% recommend their services.
Alex and his team did a first class repair job on my roof. Excellent value for my money. Kept me informed at all stages of the job, clean and tidy on completion.
Alex has just repaired chimney (putting right someone else’s bad work mainly) and ridge Used Alex before after storm in 2022 brought guttering down on my 300 yr old cottage. Measured, made and fitted within about a week thankfully after months of others roofers either not showing or making out how difficult the job was
First class conscientious and speedy roof repairs and re-roofs, worked all daylight hours to complete my new roof in late November. Went out of their way to get everything right. Highly recommended.
Prompt service and tidy workmanship when we had gutters cleaned and also some minor repairs including repairing continuous dripping when raining. Would use again.
Very happy with the quality of the repair work carried out on our roof. Reliable, and competitively priced. Professional and friendly service. Thanks.
Prompt service overall a good job and price ! Many Thanks would recommend.
Alex replaced our leaking guttering. The guttering was measured, ordered and all replaced within a week! The job was done very professionally and at a great price! Great guys, who left the area spotless, when finished. Fantastic job! Great, honest, genuine tradesman. We would highly recommend to all!!!!!
