Lead flashing costs depend on how much lead is involved and what sits behind it, so the honest answer to "how much does it cost to do lead flashing?" is that a short chimney apron is a small job and a stripped-out valley or a full roll of new lead on an abutment is a bigger one. We look, then put a fixed price in writing.

Lead Roofing Installation

Most failed leadwork was doomed the day it went on. Sheets cut too long, no allowance for movement, nailed flat where it needed to slide, no proper welt or clip. Lead expands and contracts every day of its life, and if it cannot move it splits. That is the awkward part of the job, and it is the part that gets skipped.

So we size the bays properly. We work to Lead Sheet Association guidance on codes, girth and fixing centres, which means the right thickness of lead for the detail rather than whatever is on the van. Bays are kept to sensible lengths, laps are set for the pitch, and clips are fixed so wind cannot lift a free edge.

Guildford throws up plenty of these details. Victorian terraces in the older streets, Edwardian villas, the planned housing at Onslow Village: they all carry chimney abutments, parapet gutters, box gutters and bay-window tops where lead does the waterproofing and nothing else will.

• Chimney front aprons, side soakers and back gutters
• Valley and parapet gutter linings
• Abutment flashings against walls and cheeks
• Bay roofs, porch roofs and dormer cheeks
• Hip and ridge details where lead is the sensible choice

It gets done once. Then it is left alone.

Lead Flashing Repairs in Guildford

A leak from failed flashing rarely shows up where the fault is. Water runs along a rafter, drops through a ceiling two metres away, and the stain gets blamed on a tile. So we trace it before we touch anything. Cement fillets cracked off the brickwork, lead pulled out of a raked joint, splits along a fold, sand-and-cement patches slapped over a chimney gutter: those are the usual suspects.

Repair or replace is a judgement call, and we make it in front of you. Sound lead with one split can be welded or patched properly. Lead that has been dressed to death, cut short or laid in one long strip will keep failing, and patching it again is money thrown away. We say which it is, and we say why.

If you need lead work & flashing in Guildford or flat roofing in Guildford, we cover the whole area, and the two often overlap: a lot of leaks on the older streets sit exactly where a flat roof meets an upstand and the lead cover flashing has been ignored for twenty years.

One team turns up. The same team finishes.

Lead Roof Replacement and Restoration

The bit people dread is the roof being open. Fair enough. Lead work is stripped in stages, so the section we open is the section we close the same day wherever the weather allows, and anything left overnight is covered and weighted. No half-finished chimney left to face a wet week.

Sequence, plainly:

• Survey first, including a drone view where the detail is hard to reach
• Fixed price in writing, with the codes and areas set out
• Strip and inspect the timber, boarding and any underlay behind the lead
• Rebuild the substrate where it has rotted, then dress the new lead
• Point up, clear the gutters, tidy the site, hand over the written guarantee

Rotten boarding behind old lead is common. We tell you before we price it if the survey suggests it, and if it only shows up once the lead is off, you see it and hear the number before we carry on. Scott has spent more than 36 years on Surrey roofs and answers the phone himself, so there is no site manager to chase and no subcontractor to blame. Old lead comes off and is recycled rather than binned.

Materials, Craftsmanship and Compliance

Compliance is where corners get cut quietly, because nobody sees it. Our work is done to BS 5534 for fixing and wind uplift, BS 6229 where flat roof details are involved, BS 5250 for ventilation and condensation, and BS EN 12056 for rainwater sizing when a lead gutter has to carry a real volume of water. Where a job needs building control sign-off, GOV.UK guidance on building regulations approval sets out when that applies, and we say so up front rather than after the scaffold goes up.

Milled sheet lead, correct code for the detail. Welded seams where welts will not do. Copper or stainless clips, never a nail through the middle of a sheet that needs to move.

Every job carries a 25-year written workmanship guarantee, handed over in writing before the team leaves, and it covers repairs as well as new work. If something is not right inside those 25 years, we come back and put it right.

Leadwork for Heritage and Listed Buildings

Older Guildford roofs punish guesswork. The town centre is described as medieval, with a significant area of nineteenth-century and Edwardian housing and industry at its core, and Charlotteville was developed in 1862 as one of Britain's first planned suburbs. On streets like those, a flashing that reads wrong from the pavement is a problem even when it does not leak.

So detailing is matched to what is already there: girths, rolls, welted edges and the way the lead sits into the brick joint. On a listed building or in a conservation setting, consent sits with the owner and the local authority, and we work to what is agreed rather than deciding for you. We will tell you if a repair keeps more of the original fabric than a replacement.

We work across Surrey and the Wey Valley. Guildford is home ground.
