Lead work is not a commodity service with a fixed price list. The cost of a job depends on a range of factors - the code and quantity of lead, the complexity of the detail, the access needed, and whether adjacent tiles need attention at the same time. This page breaks down how lead work is typically priced in and around Gislingham, what drives costs up and what can bring them down, so you can budget realistically and compare quotes on a like-for-like basis.
Lead is the material used wherever two roof surfaces meet and the junction must stay watertight despite the building moving. That includes chimney flashings, step flashings and soakers, valley linings, abutment flashings where a lean-to or extension meets a house wall, flat roof upstands, dormer cheeks and skylights. Each of these applications uses a different thickness of lead (described by code number) and requires different amounts of time to execute correctly.
Lead soakers are a separate component beneath the tile courses at the side of a chimney or dormer. They are often overlooked in cheaper quotes - a roofer who prices only for the visible step flashing without replacing the soakers underneath is not pricing a complete job.
Lead work costs broadly follow these ranges. These are indicative figures based on typical current UK pricing and will vary with lead commodity prices and site conditions.
VAT is additional on all figures where the roofer is VAT-registered.
Access and scaffold. The single biggest variable in any roofing quote is access. A chimney at ridge height on a two-storey property requires either a scaffold tower, a roof ladder and staging, or in some cases a full scaffold. If a scaffold is needed and shared with another trade, costs per job can be reduced - if a lead re-flash coincides with a chimney repointing or pot replacement, it makes sense to combine them. On lower pitches or single-storey sections, ladder-only access keeps the price down.
Lead code and quantity. Lead is priced by weight, and commodity prices move. Code 6 lead for a flat roof costs significantly more per square metre of material than Code 4 for a straight flashing. A roofer who uses Code 4 where Code 5 or 6 is specified is saving material cost at the expense of the job's longevity. Always ask what code is being quoted.
Chase depth and brickwork condition. If the existing mortar chase is too shallow and needs to be cut deeper - or if the brickwork around a chimney stack is loose, spalled or needs repointing before the lead can be fixed - the preparation work adds time and cost. This is legitimate; the lead cannot hold if the brickwork it is fixed into is crumbling.
Soakers. A chimney re-flash that includes new Code 3 or Code 4 soakers for every course of tile takes longer than one that simply re-dresses the visible step flashings. But soakers are part of a complete flashing detail, and omitting them is a shortcut that leads to future damp problems.
Number of sides and complexity of shape. A chimney with a straight front apron and two short runs of step flashing is a simpler job than one with all four sides detailed, a wide back gutter, and internal angles that need bossing rather than cutting. Unusual chimney profiles - octagonal pots, wide stack bases, offset positions - all add time.
Adjacent tile replacement. When lead work is stripped, the tiles around it come off too. If those tiles are found to be cracked, pegged with corroded nails or damaged, replacing them is the right thing to do. It adds to the material cost but avoids a separate call-out later.
Combining jobs. If a chimney needs re-flashing and the gutters need re-aligning or re-sealing, doing both at the same visit avoids a second access cost. Similarly, if tiles elsewhere on the roof need replacing, a visit that covers multiple items on one scaffold or tower is cheaper per item than separate trips.
Early action. A flashing that has dropped from its chase but where the lead itself is still in good condition can sometimes be re-fixed without full replacement - the chase is raked back, lead wedges driven in afresh, and the pointing renewed. Left another winter, the same lead may crack or distort, requiring full replacement. Acting early is consistently cheaper.
Accurate diagnosis. Not every damp patch on a chimney breast wall is a lead failure. Condensation, a loose chimney pot, spalled render on the stack and failed flaunching can all cause similar symptoms. A roofer who inspects properly before quoting will give you a more accurate figure than one who prices lead replacement without first checking that lead is actually the problem.
A useful quote for lead work should specify: the code of lead for each part of the job, the bay lengths that will be used, whether soakers are included, the fixing method (lead clips and wedges, not nails through the face), and what happens to adjacent tiles. A quote that says only "re-flash chimney - £X" with no further detail does not give you enough information to compare it against another.
Ask the roofer what they will do if they find soakers are missing, or if the chase needs cutting deeper than expected. A good roofer will tell you before they start, not add it to the bill at the end.
Milled lead installed to the correct specification typically lasts 50 years or more. On well-maintained, sheltered roofs the figure is often much higher - some Victorian lead work is still performing. The variables are installation quality, lead code, bay lengths and the condition of the substrate it is fixed to. A job that cuts corners on any of these will not achieve that lifespan regardless of the quality of the lead itself.
We carry out lead work across Gislingham and the nearby towns and villages, including Diss, Scole, Roydon, Bacton, Norton, Hopton, Fritton, Banham and Pulham St Mary.
