Lead Flashing Repair & Replacement in Reading

Lead flashings seal the critical junctions where your roof meets a chimney stack, party wall, dormer or abutment. When they fail, water finds a way in — often appearing far from the actual source. We diagnose accurately and fix it properly.

Why Mortar Repairs Always Fail

Lead moves. It expands in summer heat and contracts in winter cold — typically 0.3% of its length per 10°C of temperature change. A mortar seal applied over lead cannot accommodate this movement. It cracks within one to three freeze-thaw cycles and the original leak returns, usually worse than before because water has now been tracking behind the lead during the failed repair period.

Correct lead flashing repair means removing the mortar, dressing new lead into the joint and wedging the top edge into the brick course — then pointing over the top of the lead, not as a substitute for it. This is the repair that holds. It is also, unfortunately, more time-consuming than applying mortar, which is why some roofers avoid it.

Lead Flashing Locations on Reading Properties

The most common flashing locations requiring repair across Reading are chimney step and apron flashings (particularly on Victorian and Edwardian stock in Newtown, Katesgrove and Caversham), party wall flashings on semi-detached properties throughout Tilehurst and the Oxford Road corridor, and valley linings on properties with rear dormers. Flat roof-to-wall upstand details are a separate category but use the same principles.

⚠ If another roofer has applied mortar to your flashing within the last 5 years and the leak has returned — that repair has failed. Mortar is not a substitute for lead. Call us for a proper fix.

Customer Reviews

Reading Homeowners Recommend Us

★★★★★

“Had a damp patch on the chimney breast ceiling for three years. Two previous companies applied mortar — both failed within a year. Reading Roofing stripped the mortar, replaced the lead step flashings properly, and the patch has gone. Should have called them first.”

Christine W. · Katesgrove, Reading RG2

★★★★★

“Party wall flashing on our 1930s semi in Tilehurst was causing a slow drip into the landing. New lead installed in a day. Clean, neat work — the sort of job you can't see once it's done but makes all the difference.”

Alan T. · Tilehurst, RG31

★★★★★

“Chimney repointed and the lead apron replaced in the same visit. Efficient, priced as quoted, and no call-out fee. What more do you want.”

Honest advice

Do You Actually Need Roof Repairs?

Most Reading roof problems announce themselves indoors first — a stain, a drip, a patch of damp — long before the cause is visible from the ground. The trick is tracing the symptom back to the actual fault.

A damp patch or brown stain on an upstairs ceiling after rain
A slipped, cracked or missing tile visible from the ground
Water tracking down a chimney breast or around a rooflight
Debris (mortar, tile fragments) in the gutters or on the drive
Daylight visible through the roof from inside the loft

When it is not the answer: If more than about a third of the covering has failed — widespread nail sickness on a 1960s-70s Whitley or Southcote estate roof, for instance — repairing tile-by-tile is money wasted. Read the full guide.

The process

What to Expect: Roof Repairs in Reading

1. Free survey

We inspect from roof level, lift sample tiles to check the fixings and underlay, and trace the leak to its real source — not the nearest visible symptom.

2. Written itemised quote

You get a fixed, written price naming the fault, the fix and the guarantee — no lump-sum guesswork.

3. Scheduling

We agree a date; for common faults we carry matching materials to fix on the first visit.

4. The repair

We carry out the work, document any hidden damage found with photos, and make the roof weathertight.

5. Cleanup & sign-off

We clear debris, leave the site tidy, and hand over the written workmanship guarantee.

Timescales

Typical Timescales

Job	Typical duration
Slipped or cracked tile refix	1-2 hours
Lead flashing repair	Half a day
Section of nail-sick tiles refixed	Half to full day
Rear valley rebuild	1-2 days
Chimney flashing renewal	1 day

Wet or high-wind days pause tiling and lead work — we build weather margin into every booking and never leave a roof open overnight.

Access

Access, Scaffolding & Permits in Reading

Most Reading repairs run from roof ladders or a tower; scaffold is quoted only where the job needs safe standing time at height. Scaffold is specified for: chimney-side repairs, full valley rebuilds, ridge work on exposed Tilehurst and Caversham Heights streets, or anything beyond a day at height - always itemised in your written quote, never a hidden extra, and we arrange it.

Reading's mix of Victorian terraces in Newtown and Katesgrove and post-war estate housing in Whitley and Lower Earley means access varies from tight terraced frontages to open estate driveways. Pavement scaffold and skip permits go through Reading Borough Council; allow a few working days on streets like Newtown terraces off the Oxford Road, the narrow streets of Katesgrove where space is tight.

What the 10-Year Guarantee Actually Covers

Workmanship on the repaired section is covered for 10 years in writing; any replacement tiles and lead carry manufacturer warranties on top.

Covered: workmanship for 10 years, in writing, transferable if you sell.
On top: manufacturer warranties on materials (terms vary by product).
Not covered: storm or impact damage - that is an insurance matter, and we will document it for your claim.

If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.

Good to know

What It Is Like While We Work

A day of ladder or tower work and a small amount of tile debris — we sheet below the work area and clear everything before we leave. You do not need to stay home for external work - we just need power and access agreed in advance.

Repairs run year-round; temporary weatherproofing goes on the same day if rain stops work mid-job. Thames Valley humidity and the Kennet and Thames river corridors slow drying and accelerate moss, especially on north-facing slopes.

FAQ

Lead Flashing Questions

Replacing a short section of apron or step flashing on a chimney stack in Reading typically costs £280–£550 including lead and labour. Longer runs, such as replacing a party wall flashing on a semi-detached, run £450–£900 depending on length and height. We provide free quotes.

The most obvious sign is a damp patch on the ceiling or wall directly below or adjacent to where the flashing runs — typically at the base of a chimney stack, at a roof-to-wall abutment, or along a valley. Mortar bodge repairs over original lead that have cracked or separated are a reliable indicator. We can confirm on a free inspection.

Most original lead flashings on Reading's Victorian and Edwardian stock are now 80–120 years old. Lead fatigue from thermal cycling eventually causes micro-cracking. The more common failure mode, however, is a previous 'repair' using mortar to seal a gap rather than replacing the lead — the mortar fails within a few years as the lead moves seasonally, and the problem returns.

Short sections with localised damage — a crack, a lifted edge, a failed welt — can often be repaired using lead burning or lead adhesive. If the flashing is original and showing widespread deterioration, replacement gives a better long-term outcome. We'll recommend repair where it's genuinely appropriate.

Correctly installed code 4 or code 5 lead flashing has a service life of 50 to 80 years. Most premature lead failure in Reading is caused by mortar applied over the lead rather than proper installation. Where original lead is intact and sound, we repair rather than replace. Where it has been repeatedly bodged, full replacement is the only lasting fix.

Lead expands and contracts significantly with temperature. If the top edge is mortared flat to the brick face, that mortar cracks within one or two thermal cycles. The correct method is to rake out the joint above, insert the folded lead edge, drive in lead wedges, and point over the wedges only — allowing the lead to move without breaking the seal.

Yes. Code 4 and code 5 lead is the standard for traditional flashing profiles. For listed properties in Newtown or conservation area properties in Caversham, we work to original details and consult with the planning authority where material or profile changes might require consent.

Our Approach

Lead Flashing Work in Reading

Lead flashing repair is one of the most misrepresented jobs in the roofing trade. The majority of repeat-failure chimney leaks we investigate in Reading trace to mortar applied over lead flashings — typically by a previous contractor looking for a quick fix. Mortar cannot flex with lead's thermal movement. It cracks within one to two winters and the leak returns.

Correct lead flashing repair means removing any existing mortar patches, assessing the lead for remaining serviceable life, and either redressing sound lead back into the brick joint correctly or replacing failed sections with new code 4 or code 5 lead. The top edge is wedged mechanically into the raked-out brick joint and pointed only over the wedge — not over the face of the lead.

We carry code 4 and code 5 lead sheet and standard flashing components on our vehicles at all times. For standard chimney flashing replacement on a typical Reading semi-detached, the work is typically completed in a single visit once scaffold is erected. For complex back gutters and multi-stepped arrangements on Victorian terrace chimneys, we allow an additional half-day.

Lead Code Selection for Reading Properties

Code 4 lead (1.8mm nominal thickness) is the standard for step flashings, cover flashings and soakers on domestic properties. Code 5 lead (2.24mm) is used for back gutters and horizontal applications where the greater thickness is warranted by the catchment area and water loading. We specify code 5 for all new back gutter work regardless of the original specification, since under-specified original lead is often the root cause of the failure we are addressing.

On conservation area properties in Newtown, central Caversham and Katesgrove, lead is the only accepted flashing material — aluminium or GRP alternatives are not acceptable replacements. We are familiar with the planning requirements for these areas and specify accordingly.
