Project information:

The conservation of Leinster House began in 2018 and M&I Lead were appointed as the Lead work, Copper work and Slating contractor by the main contractor, Duggan Brothers Contractors Ltd.

The original standard of workmanship and design on this Historic building was very poor and repairs had been continually carried out over many years.

A total re-design of the Lead work to every area of the building was required to bring it up to the code of practice BS6915 and to pass LCA inspections required for the insurance backed guarantee scheme.

The works carried out by M&I Lead included.
Lead covering to all stone projections on the facade, window hoods, door hoods and hundreds of metres of cornice and string course.

Deep sided box gutters to the whole perimeter of the outside roof were lined with .8mm to 1mm hard temper copper, provision for large catch-pits, outlets and over-flows were also made.
Lead capping to the outer blocking stone and copper box gutter intersection.
The Bow roof on the north elevation received new copper box gutters, copper cladding, Lead capping/cornice and slating.

Large lead roll to hip's and ridge's on the main roof, lead covered portico on the west elevation.
Lead flat work to the inner roof area, including dormers, vents, chimney stacks and countless miscellaneous flashings.
M&I Lead also carried out all the slating to the main roof and inner roofs using salvaged blue bangor slates.

In total some eighty tonnes of lead sheet was used, ranging from code 6 to code 12. Four tonnes of .8mm and 1mm hard temper copper and eighteen thousand blue bangor slates were used on this major conservation project.
The works were inspected on three separate occasions by the Lead Contractors Association (LCA) and an insurance backed guarantee certificate for workmanship and material, underwritten by Llyods of London was issued to the client.
