Setting the standards for leadwork

This beautiful garden Gazebo was constructed by Robin Godden Leadwork of Essex with the structure from Clacton Garden Terraces. Robin works with all types of leadwork from cathedral roofs to decorative garden pieces and you can view more of his work on his website gallery via www.robingoddenleadltd.co.uk

Contractors wishing to join the LCA must submit three examples of their work to be assessed by a nominated LCA vetting officer, normally a member of Council. The design and application skills viewed on site will be graded and a subsequent recommendation made to the Chairman of the Vetting Committee, who will then report to Council. 

S (Satisfactory) The applicant has demonstrated a level of skill and knowledge to an acceptable standard, but a further vetting will be required during the following year.

G (Good) Not only was the work viewed to an acceptable standard but the applicant was able to demonstrate a degree of additional care and attention to detail which exceeded the minimum requirement. An applicant receiving a “Good” grade will not need to be vetted again for two years.

This Votive candelabra for Wayboune Church in Norfolk was created by Brian Turner of Turner's Ornamental Leadwork. It was a change from the normal lead work they are commissioned to produce, examples of which can be seen on the website at www.turners-lead-collection.co.uk

E (Excellent) The applicant was able to demonstrate comprehensive knowledge in all aspects of leadwork design and an application skill in a complex or demanding technical situation in order to maximise the integrity and durability of the material. An applicant receiving an ‘Excellent’ grade will not require further vetting for three years. 

There is also an F (Fail) whereby the applicant has failed to demonstrate the required standard of knowledge or skill and will not be accepted as a member.

This dome project by SWG Roofing was based on a private house in Surrey. As you can see by the top image the condition of the dome when the lead coverings were taken off was very poor. SWG Roofing rebuilt the framework in new timber then added the new lead covering. For more from this company visit their website www.swgroofing.co.uk

Becoming accepted as an LCA member though is not the end of the assessment programme, as all LCA members must continue to regularly submit their work as part of an annual vetting programme.

Directed by the Chairman of the Vetting Committee, Council members voluntarily conduct assessments of members’ work, the frequency being determined by the previous vetting grade achieved. Existing members continue to be graded the same way as new applicants.

Any member that cannot maintain the minimum standard and subsequently “fails” their vet is ultimately required to withdraw from membership.

The vetting programme cannot be avoided, as any member unable to provide appropriate examples of their workmanship for vetting is not allowed to feature in the annual directory, which is the main promotional opportunity for members. (click here to get your copy)

All vetting grades now appear alongside the details of each member in the LCA Directory of Specialist Leadwork Contractors, which is distributed free to architects, surveyors, specifiers, main contractors and clients.

Any member continually unable to provide appropriate examples of their workmanship is ultimately required to withdraw from the Association

Murdoch winner 2017 keeps the roof watertight for Sotheby's rare items

The LCA has held awards for best work from its members for the last 21 years. The Murdoch Sponsors Award was added some ten years ago for the smaller installations that used less than five tonnes of lead sheet, but which could be equally as demanding of the leadworker’s skills as the larger, more eye-catching projects. 

In 2017, the winner of the award was in no doubt - Leadwork Contracts Ltd for their work on Sotheby’s, George Street, London.

Residential Mews House, London SW1 by BS Leadworks

Situated behind large houses in a built up area of the city, the Mews House was originally used as stables with living areas above. Along these narrow streets are some of the most spacious, luxurious houses you could find. BS Leadworks carried out a total re-roof including box gutters, dormers, flat roof, pitched roof and flashings. Unlike when the house was originally built, they had a duty to vent the roof allowing it to breathe.

The rear box gutter was designed by the architect to fall into sump outlets and down through internal rainwater pipes. LCA members BS Leadworks fitted Code 8 lead, laid on underlay - this was ideal because it meant they did not have to step the box gutter and it could be laid in two runs due to the size allowance for Code 8.

The dormer cheeks were clad in Code 5 and the roof was completed using Code 6 in a four bay formation. This extra roll in the dormer would slow the water down as it falls off the flat roof at the top of the dormers. The top flat roof is vented at the front of the roof and returned out through a vented ridge detail.

The rear pitched area is vented in the same way. Wood rolls were used for the joining method and Code 6 lead was laid on underlay fixed with copper nails. On the ridge details they had to allow for a ventilation gap which was built by carpenters with stainless steel fly mesh to stop any insects.

Finally they capped in Code 5 lead using welts for joins and fixed with copper ring shanked nails.
