Use of lead in construction and roofing

The natural properties of lead make it as suitable a roof covering today as it did hundreds of years ago.

Lead is soft, heavy, highly malleable and ductile (easily formed molded or shaped); it has a low melting point (327.46 C), is non combustible and is a poor conductor of electricity. Lead is also very resistant to corrosion.

Working with lead in the building trade has always required people with appropriate skills and the trade that derived its name was ‘plumbers’, from the Latin word for lead: plumbum.

The skilled trades’ people worked with lead water pipes and used lead solder.

Lead is considered stable and like another heavy metals, lead is a potent neurotoxin that can accumulate in soft tissue and bone if exposure continues over time.

Uses of lead in Roofing

  • soakers
  • flashings
  • pitched roof gutters
  • cladding for windows and roof furniture
  • parapets
  • flat roofing

History of Lead in Construction and Roofing

The Romans and then Normans first utilised lead as a building material in pipes and roof coverings sheets because it is both stable and weatherproof qualities and its high resistance to atmospheric corrosion.

Plumbers

The original word plumber originates from the old English word "plummer", from the old French word "plomier", from the Latin "plumbarius" for lead worker that was derived from the Latin word for lead: plumbum.

When freshly cut the metal has a silvery bluish white colour but tarnishes quickly to dull grey when exposed to air.

The traditional lead roof on many English Churches and Cathedrals may well have stood the test of time over hundreds of years mainly because of the durability and lifespan of the material and sound construction principles used.

English Heritage which manages many of England’s best historic and Grade I II & III listed buildings, concluded the suitability of the material in construction from research into lead durability and fitness for purpose, finding that in general, if no unusual decay is encountered during roof repair, there is no need to alter the constructional form and detail of an old lead roof.

Refurbishment or replacement of lead roofs on older and historic buildings is achieved economically by striping off the lead and recycling it.

The value of the stripped lead can be put to the price of the new roof that uses modern and durable construction methods the longevity of which produces a positive environmental impact.

Durability and recycling provides considerable value for money, alongside the significant aesthetic value.

Historically in the UK, lead has had a poor press because of public safety concerns over its use in water pipes and paint, this practice is now unlawful but there remains a danger when handling lead because it acts as a cumulative poison. At K-Roofing, we follow LSA safety precautions for handling lead.

Modern construction methods use both traditional and innovative techniques in lead application and these are governed by Building Regulations, British Standards and the Lead Sheet Association.

Quality Standards in Lead Use

Lead is a stable metallic element that appears in the Periodic Table of Element Symbol using the symbol Pb, and as such has very predictable and controllable qualities.

Because of consistent qualities the building, plumbing and roofing professions have gained considerable knowledge and experience in its application and use.

Our lead sheet and work is fitted in accordance with BS6915 and LSA’s Lead Sheet Manuals. We only purchase supplies manufactured by members of the Lead Sheet Association.

Members manufacture rolled lead sheet to British and European Standard BSEN 12588:1999 for the UK construction industry.

Rolled lead sheet to BS EN 2599: 999 provides a uniform thickness within a tolerance of +- 5 of stated thickness.

The lead sheet is free from laminations and surface marks and it is allowable that there may be bands or areas of rainbow colours that do not normally affect the life or performance of the lead sheet.

Patternation oil is used to reduce the initial risk of staining where rain from lead flashings and weathering drain onto other surfaces until the natural lead patina begins to form.

Patternation oil may also be used to ensure a uniform finish to larger areas of lead sheeting though it must be applied to the sheeting before any weathering begins.

Lead, the Environment and Recycling

Lead is chosen for use in construction due to its resistance to corrosion and longevity. Its resistance to leaching into the environment, and its exceptional recycling properties make it unique as a building product.

Only when lead is freshly cut lead is the shiny bluish-white surface exposed, however when this tarnishes to dull grey rapidly as the surface oxidises.

The patina forms a protective layer that prevents further corrosion or leaching into the environment.

Any leached products that do leave the surface of a lead roof for instance, are at trace levels and highly diluted by rainwater.

Building Regulations and British Standards means that correctly fitted roofing lead is designed so that gutters with drainage points so that should there be trace level release of lead into the environment it will have almost no environmental impact.

Lead is 100% recyclable and neither degrades or decays. The recycling process requires less energy than the original ore smelting process used to create it. It is an efficient and cheap process due to the low melting point of the element.

This ease with which lead can be recycled and its economic value ensures that a viable scrap lead recovery network in the UK remains.

More than 95% of lead used in building is recycled, greater than other substitute products.

Every year 3 million tonnes of lead are recycled from scrap — roofing, pipes and batteries.

The ‘substitution effect’ also means that by choosing lead builders and reducing demand for other less environmentally friendly synthetic materials which cannot be recycled.

Building Design in Lead

Lead has an aesthetic quality that weathers to a timeless natural look.’

Lead enhances buildings visually and protects from the elements. The natural properties of lead make it a versatile material for the building trade to use.

Lead can be used to embellish and enhance architectural design, for practical functionality such as weatherproofing and channeling precipitation (the element for the elements) and as a soundproof material.

Working with Lead

Good practice in construction design and material choice ensures that when chosen, lead is designed in with adherence to industry standards and an understanding of its properties. This prevents inappropriate use and ensures that lead applications lasts the test of time.

At K-Roofing, we appreciate and understand the nature and use of lead in the construction industry, and we adhere to the Lead Sheet Association regulations when working with the metal.

We are members of the Lead Sheet Association and the Lead Contractors Association, and relevant have staff are trained by their Training Academy.

We regularly work with professionally qualified consultants, such as architects and surveyors in the building industry to carry out many successful projects and installations throughout Manchester and the Northwest UK. We also work in a larger radius into Wales, Derbyshire and Yorkshire.

K-Roofing is a leading roofing contractor in the UK, always working to approved standards and practices to bring to clients the highest industry standards possible.

Future of Lead in Buildings

Lead has a considerable future in UK roofing and construction.

It is almost unparalleled in for its longevity, malleability, resistance to weathering and recyclability.

Used in modern building techniques such as a roofing membrane, surmounted by lightweight roofing panels, insulation and a cement-like upper surface it adds to a roof life expectancy by up to 4 times that of other existing flat roof systems.

Lead roofing products also include pre-manufactured tiles to weatherproof roof pipes (eg. flue pipes, en-suite flues) and masts that pass through the roof.

At K-Roofing, we use lead-rubber weathering slates that form an effective weatherproof seal between a tiled or slated roof.

The lead and rubber are bonded, vulcanised together resulting in a chemical lock between the materials.

Lead is reliably used in guttering with gutter strip joints used to allow for thermal expansion. Lead gutters are installed with steps at regular intervals.

We also use a strip joint system that is designed to be built into a one piece lead gutter to allow for thermal expansion/contraction with temperature change. Metal fatigue is prevented and the seal is watertight and has a long life expectancy.
