The LSTA (originally established as the Lead Sheet Association, or LSA) was founded to promote, support and set consistent standards for the use of rolled sheet lead in the construction industry.
It is the main industry body and the UK authority on rolled lead sheet. Its purpose is tied to improving practices across construction work where lead is used. Quality forms the core of what guides its ongoing work in the field today.
Their primary aims are:
• Setting technical standards
• Providing expert training
• Offering technical support
Before the LSTA was founded, leadwork training in the UK had no formal national structure. Knowledge was passed down through direct experience; skilled leadworkers taught apprentices on the job, with standards varying considerably from one contractor to the next. There was no consistent benchmark for quality, no nationally recognised qualification, and no unified body to represent or develop the trade.
The Lead Sheet Association was established to address this gap. It brought together manufacturers, contractors, and training bodies to create a shared framework for the leadwork industry, one that could raise standards, reduce failures, and protect the long-term reputation of lead as a roofing and cladding material.
In 2018 the Lead Sheet Association became the Lead Sheet Training Academy under new direction with Nick DuGard who lead the organisation to the next level.
Before the LSTA:
• Learning often happened through hands-on experience
• Knowledge was passed on by working alongside others
• Training took place without formal structure
• Guidance arrived through observation and repetition
• Skills developed over time in real settings with no consistent national benchmark for quality
After the LSTA:
• Training programmes became more structured
• Aligned with national qualifications like NVQs
Working with organisations such as:
• City & Guilds
• Construction Industry Training Board (CITB)
This change marked a shift from craft tradition → formalised professional standard
Over time, LSTA guidance became closely aligned with:
• BS 6915
• BS EN 12588
The LSTA doesn’t replace existing standards, but demonstrates their correct application within real-life settings.
Today, the LSTA is:
• A centre of excellence for leadwork training
• A key part of heritage construction and conservation
• A benchmark for quality assurance in roofing projects
It supports:
• Roofing contractors
• Apprentices and trainees
• Conservation specialists
• Architects specifying leadwork
Modern LSTA guidance now covers:
• Advanced detailing (chimneys, dormers, valleys)
• Heritage restoration techniques
• Environmental and sustainability considerations
• Digital learning and structured assessment
LSTA guidelines are built around four principles:
• Durability: lead roofs should last 50–100+ years
• Flexibility: allow for thermal movement
• Weatherproofing: watertight detailing is critical
• Workmanship quality: neat, consistent finishes
The LSTA guidelines cover a complete framework:
Material & sheet sizing
• Using the correct thickness of lead
• Using lead sheet coded to BS EN 12588
• Sheets being limited to the maximum recommended sizes
Fixing methods
Correct use of:
• Clips
• Nails (non ferrous)
Substrate Requirements
• Proper timber boarding or suitable base
• Ventilation to prevent condensation
• Adequate falls for drainage
Detailing Standards
High emphasis on key junctions:
• Chimney flashings
• Roof valleys
• Parapet walls
• Gutters
Most failures happen in detailing, not flat areas.
Health & Safety Guidance
LSTA embeds safety into all training:
• Manual handling of heavy lead sheets
• Work at height (roof safety)
• Tool safety (cutting, welding)
• PPE requirements
Best Practice Standards
LSTA promotes consistency across the industry:
• Use of patination oil to prevent staining
• Clean, uniform finishes
• Standard detailing templates
• Correct sequencing of installation
Following LSTA guidelines helps ensure:
• Longer-lasting roofs (often decades longer)
• Fewer installation problems
• Compliance with UK building standards
• Preservation of traditional craftsmanship
Leadworx manufactures all products to BS EN 12588, the standard recognised by the LSTA. Every piece of lead that leaves our facility is produced with quality, safety, and longevity in mind: from correct lead codes and non-ferrous fixings, to responsible recycling of all off-cuts. It’s the same commitment to standards that the LSTA has championed across the industry for decades.
