The reroof of a church and stable block in Welsh Slate by Maguire Brothers wins them an award shortlisting.
The reroof of part of a Grade II listed church and an adjoining stable block has earned the specialist contractors a place in the finals of some national awards.
Work on the south aisle roof over the Lady Chapel of St Andrew’s Church on Ham Common in Richmond, Surrey, has won Maguire Brothers a shortlisting in the “Best use of slate for a commercial project” category of the Pitched Roofing Awards 2024.
The Surrey-based contractors were called on by the “Chapel on the common” when the original Welsh slates required replacing after more than 160 years. A fundraising campaign raised the £140,000 required and 250m2 of Welsh Slate’s 600mm x 300mm Penrhyn Heather Blue slates were installed by Maguire’s over the spring/early summer.
Due to the historical nature of the building (the church was built in 1831 and the south aisle added in 1857), a careful and precise method of installation was adopted by Maguire Brothers, ensuring that the work was in line with the building’s listed status.
The roofing process, which took place while the church remained operational, involved removing the old slates, felt and battens, paving the way for the installation of a breather membrane on the lower mansard part of the roof to provide thermal value.
The loft area above the mansard section was also insulated with loft roll insulation for enhanced energy efficiency. A breather membrane was then installed above the mansard section, followed by treated counter battens and battens to support the new slates, fixed with copper nails for a secure fit.
Maguire Brothers director Milos Maguire said: “Our decision to use high-quality Welsh slate for this project was driven by a commitment to preserving the authentic look and character of this Grade II listed church, while ensuring long-term durability and longevity.
“One of the key factors in choosing Welsh slates was their high-quality natural appearance. We recognised the importance of maintaining the architectural integrity of the church, and these slates perfectly matched the authentic look of the existing roof. Their elegant texture and rich color variations helped us create a seamless blend with the surrounding environment, preserving the church's historical charm.”
He added: We carefully considered the lifespan of the selected slate materials. Welsh slates have been renowned for their exceptional longevity, outperforming many other slate types. This was a crucial factor in our decision-making process, as we aimed to provide a roofing solution that would endure the test of time. We ensured that the church's roof would not only retain its beauty but also offer enhanced durability, withstanding the elements and requiring minimal maintenance for years to come.”
The building was surrounded by a historic graveyard, and additional care needed to be taken to ensure none of the surrounding grounds were disrupted during the 10-week-long works.
Further works included the refurbishment of the 250m2 roof of the stable block. By sorting, re-holing and reusing existing slates from the aisle roofs, Maguire Brothers not only preserved the historical integrity of the structure but also significantly reduced waste. This careful approach ensured that the stable block received a new, insulated roof, enhancing its energy efficiency while maintaining its heritage aesthetic.
Milos explained that their commitment to sustainability and environmental responsibility was also a driving force behind their material selection.
“Welsh slates are a natural and environmentally friendly choice, as they are sourced from quarries known for their responsible extraction practices. By utilising these slates, we reduced the project's carbon footprint and contributed to the preservation of our natural resources.”
The project was completed on time, on budget, and to the client's approval.
“Our decision to use high-quality Welsh slate was instrumental in achieving these successful outcomes,” said Milos. “We maintained the church's authentic appearance and historical charm, seamlessly blending the new roof with the existing architecture. Welsh slates ensured that the roofing solution would stand the test of time, reducing future maintenance needs and costs. This long-lasting material choice contributed to completing the project within the specified timeframe and budget.”
The finals of the Pitched Roofing Awards will be held in Manchester on November 24th.
