Leadwork Specialist Glasgow
Lead remains the premier material for waterproofing critical roof junctions, valleys, chimney bases, and flat bay roofs across Central Scotland. Known for its unmatched malleability, longevity, and natural resistance to atmospheric corrosion, professionally installed lead sheet can easily protect a building for well over a century. However, leadwork is a highly specialist trade requiring deep craftsmanship to handle proper thermal expansion, avoiding premature cracking, splitting, and structural water ingress.
At Kenna Roofing (K&G Roofing Ltd), we have the expertise and experience to install, dress, repair, and maintain all forms of lead roofing across traditional tenements, historic villas, and modern domestic properties in the Glasgow area. Our skilled slaters work strictly with high-grade Code 4, Code 5, and Code 6 milled lead sheet to exact Scottish building standards—ensuring a 100% watertight seal that stands up to West Coast gale-force weather.
Lead Roofing & Traditional Lead Flashing Services Glasgow
Because lead expands and contracts significantly with atmospheric temperature changes, installing long lead runs without correct expansion joints causes the sheet to buckle, split, and leak. Mastering the correct lap lengths, fixing methods, and patination oil treatments separates master slaters from general builders.
Code 4, 5 & 6 Rolled Lead Sheet & BS EN 12588 Compliance
We specify rolled lead sheet manufactured to British Standard BS EN 12588, matching the exact code thickness to your specific roofing application:
- Code 4 Lead (1.80mm thickness): Ideal for vertical cover flashings, chimney step flashings, soakers, and small gutters.
- Code 5 Lead (2.24mm thickness): Recommended for heavy-duty roof valleys, main chimney aprons, back gutters, and small flat bay roofs.
- Code 6 Lead (2.65mm thickness): Specified for large flat lead roof bays, parapet gutters, and extensive architectural lead cladding requiring maximum durability.
Every leadwork project completed by Kenna Roofing is treated with specialist patination oil upon completion, preventing initial carbonate staining from running down surrounding slate, tile, or sandstone surfaces.

Lead Valleys, Chimney Flashings & Soakers
Roof junctions where two sloped roof pitches meet, or where pitched roofs abut vertical brickwork or sandstone chimney stacks, represent the most vulnerable areas on any Glasgow building.
Chimney Aprons, Back Gutters & Step Soakers for Slate Roofs
Our slaters dress Code 4 and Code 5 lead into custom step flashings, front aprons, and deep back gutters around weathered chimney stacks to block water ingress at the roofline interface. On slated roof pitches, we interleave individual lead soakers beneath every slate course, creating an invisible, impenetrable barrier along side abutments and wall junctions. When lead valleys age and split, we carefully strip back adjacent slate courses, renew underlying sarking boards, and dress new Code 5 lead valley linings securely in place.

Operated Cherry Picker Hire & High-Reach Leadwork Access
Executing high-level lead repairs on multi-storey sandstone tenements or high residential chimney stacks usually involves heavy scaffolding setup costs, council pavement permits, and street disruption.
| Traditional Multi-Storey Scaffolding | Operated Cherry Picker Access (MEWP) |
|---|---|
| High setup costs & permit delays | Fraction of the cost with zero permit delays |
| Blocks driveways & pavements for weeks | Rapid deployment with zero ground footprint |
| Security risks for ground-floor flats | Vehicle leaves site at the end of the day |

Scaffold-Free Lead Repairs for Multi-Storey Sandstone Tenements
By operating our own fleet of narrow-chassis truck-mounted access platforms (MEWPs), Kenna Roofing reaches elevated tenement gutters, high chimney flashings, and rooftop lead bays quickly and safely. Every platform hire includes an experienced, IPAF-certified operator to maneuver the platform basket, allowing our slaters to complete lead repairs without scaffolding hassle. Surveyors, property factors, and trade contractors can view our operated cherry picker hire Glasgow options for flexible booking schedules.
Slaters & Tilers Glasgow: Leadwork & Slate Roof Integration
Leadwork is intrinsically tied to slate and tile roofing. Installing a lead valley or lead hip flashing requires expert knowledge of slate trimming, diminishing course layouts, and copper nail fixing. Our skilled slaters ensure lead details integrate seamlessly with surrounding roof coverings without restricting water runoff channels. For comprehensive period roof restoration, check our specialized slate roof repairs Glasgow, tile roof repairs Glasgow, and tenement roof repairs Glasgow pages.
Flat Lead Bay Roofing, Cappings & Cladding
Flat lead bays over entrance porticos, bay window tops, and dormer roofs are architectural highlights of traditional Glasgow homes. However, poorly dressed lead or failed seams quickly cause internal ceiling leaks.
Porticos, Bay Window Tops & Architectural Leadwork Cappings
We construct and repair flat lead roofs using traditional wood-cored rolls and drip joints to accommodate thermal movement safely. Additionally, we fit protective lead cappings and lead cladding over exposed sandstone parapets, wall copings, and window sills to stop rainwater from saturating external masonry and causing stone spalling. Learn more about secondary eave protections on our roofline repairs Glasgow and gutter repairs Glasgow pages.

Essential Checklist for Roof Leadwork Health
Run through this quick 5-point leadwork health check annually or after severe weather:
- Inspect Chimney Base Flashings: Look up from street level to check whether lead step flashings around chimney stacks appear loose, lifted, or pulled out of mortar joints.
- Review Lead Valleys: Look for dark water staining or visible splits along visible lead valley channels between sloped roof pitches.
- Check Bay Window Tops: Inspect internal ceilings below bay windows or entrance porticos for damp spots or yellow water rings.
- Look for Carbonate Runoff Stains: Check surrounding slates or sandstone walls for white streak staining caused by untreated leadwork.
- Schedule an Aerial Lead Survey: Book a scaffold-free cherry picker survey to spot split lead seams before rainwater penetrates loft timbers.
Frequently Asked Questions (FAQs)
1. Why is lead used for roof flashings and valleys in Glasgow?
Lead is exceptionally durable, highly flexible, and naturally resistant to corrosion from West Coast rain and severe weather. When correctly dressed by skilled slaters, lead forms a 100% watertight seal that expands and contracts without cracking, lasting 100+ years.
2. What causes lead flashings or lead valleys to split and leak?
Lead splits when sheets are installed in oversized single lengths without thermal expansion joins (such as drip joints or wood-cored rolls), or when incorrect lead codes (too thin) are used. Natural expansion and contraction under summer heat and winter cold cause the lead sheet to buckle and split along flex lines.
3. What are lead “codes” and why do they matter?
Lead code refers to the thickness and weight of the rolled lead sheet per square metre. Code 4 (1.80mm) is used for light flashings and soakers, Code 5 (2.24mm) for heavy-duty valleys and chimney gutters, and Code 6 (2.65mm) for flat lead roofs and parapets. Using the correct code prevents premature fatigue and wind lift.
4. What is patination oil and why do you apply it?
Patination oil is a specialist coating applied to freshly dressed lead sheet. It prevents white lead carbonate powder from forming on the lead surface during damp weather, stopping unsightly white streaks from running down surrounding slate, tile, or sandstone masonry.
5. Can split lead flashings be repaired, or do they need full replacement?
Minor splits can sometimes be temporarily sealed or lead-welded, but if a lead valley or apron has reached the end of its structural lifespan and suffered widespread thermal fatigue, replacing the section with new Code 5 lead is the only permanent solution.
6. Do I need scaffolding to repair lead flashings on a tenement?
In most cases, no. Our truck-mounted cherry pickers reach high tenement rooflines safely within 10 minutes of arriving on site, saving property owners hundreds of pounds in scaffolding setup fees.
7. What areas of Greater Glasgow do you cover?
We serve all districts across Greater Glasgow, including Chryston, Bishopbriggs, Kirkintilloch, Cumbernauld, the West End, Southside, City Centre, Dennistoun, and surrounding Lanarkshire towns.
