Roofing contractor: Cobain Roofing, The Wirral

Major £20m re-development

SIGA Natural Slate was specified for a major £20m re-development by the PJ Livesey Group at Manchester Metropolitan University’s former Didsbury campus. Pitched roofs to 57 houses and 36 apartments will all be roofed in SIGA 112S slates from the Excellence range.

Designed by Calder Peel Architects, these new homes at St James’s Park are part of the developer’s scheme to regenerate this 17-acre heritage site by mixing heritage buildings and new homes in a mature setting.

PJ Livesey places an emphasis on getting the balance right between conservation and a more contemporary approach to bespoke new build housing and includes outside space, high quality architecture and the retention of trees.

SIGA 112S match for Welsh Blaenau Ffestiniog slate

The choice of slate roofing materials was architecturally sensitive. SIGA 112S was selected as an excellent match for Welsh Blaenau Ffestiniog slate which has been used predominantly in the Manchester area and surrounding towns but is now extinct.

Approved for use in the Snowdonia National Park, SIGA 112S is sourced from some of the finest slate seams available in Spain. An excellent colour match, it combines exceptional durability with outstanding workability, along with minimal sorting requirements. The texture and appearance are typical of a first-selection

La Bana Hebra slate, with a fine vertical grain. SIGA 112S natural slates are guaranteed for 75 years and are NHBC approved.

Roofing contractor: Pinnacle Roofing, Roslin

Stylish development in landscaped setting

Sitting in a beautiful, leafy area in one of Scotland’s largest cities, Oakwood Court is the latest development from McCarthy & Stone. Providing retirement living accommodation in a relaxing, landscaped setting, the development aims to combine impeccable style with all the comforts of a managed property.

Designed by LDN Architects of Forres near Inverness, as part of a wider masterplan at the former UHI Midmills Campus, the development of 53 purpose-built one and two-bedroom apartments benefits from proximity to Inverness city centre and its wealth of amenities.

Planning challenges

The wider masterplan sees the former campus reformed with new residential developments, and a new creative hub within a category A listed building. The redevelopment of the campus has allowed for the site to be opened up to the public, with improved sightlines and visual amenity, improved connections to the city centre, and increased green space.

LDN needed to meet two planning challenges for the development; building within the Crown Conservation Area of Inverness and creating complementary aesthetics for a project which is adjacent to Category A listed buildings.

LDN Architects specify SIGA 35

Based on previous experience with the product, LDN specified SIGA 35 as its blue-grey colour and heavy texture provide a close match for Scottish slates.

£1m refurbishment

Glasgow Kelvin College (GKC) is the newest of Glasgow’s three regional further education colleges. Constructed using red sandstone in 1905 for Maryhill School Board, the building was first known as the Garrioch Public School. Today, formed by the merger of John Wheatley, North Glasgow and Stow colleges in November 2013, GKC can now ensure that students benefit from a high-quality learning environment.

In 2017, a major £1m refurbishment project was undertaken at the college. The scope of works to the Category B listed building included refurbishment to roofs, pathways, ramps and drainage problems as well as listed buildings works, including slating, stonework, leadwork, glazing/windows and timber preservation for the treatment of dry rot and timber decay.

“The property is one of 61 Category B listed buildings in Glasgow and  specification of a slate that would provide a unique, indigenous alternative to traditional Scottish slate was essential to the conservation of the local built environment.”

Iain Gordon, Head of Facilities and Environmental Sustainability at GKC

Project: Chapelton, Seamill, West Kilbride
Slate supplied: SIGA 67ATG
Roof area: 125 prestigious period-style properties
Main contractor: Hope Homes, Ayr
Roofing contractor: Scott Roofing Services, Troon

Scottish inspiration using natural materials

Hope Homes have taken inspiration from Scottish domestic architecture of the late 17th to the mid-19th century to create their latest development, Chapelton, in the thriving seaside town of Seamill, West Kilbride.

Attention to detail is paramount at the development and a total of 125 prestigious, two, three, four and five bedroomed period-style properties are being solidly built from natural materials such as slate, sandstone and larch.

A key challenge was to specify slates which offer uniformity in finished appearance but meet the needs of varying roof pitches. For example, the five bedroomed Admiral property is built to a typical Georgian design which has a shallower pitch and required a larger slate than the single storey cottages and other house types. SIGA’s sizing options were able to facilitate each specification, providing aesthetic uniformity.

Working closely with the London Borough of Tower Hamlets, The Breyer Group’s roofing division selected SIGA’s most popular slate, SIGA 39 at 500 x 250mm as the closest match for existing materials predominant in the area.

“SIGA 39 represents excellent value for money when compared to the cost of similar new slates. Like any public project, the specification of materials needed to meet both budgets and aesthetics. SIGA provided a range of product samples prior to refurbishment of the 500m2 roof.”

Steve Linwood, building surveyor, Tower Hamlets

SIGA 39 is an outstandingly successful first selection slate from the Specification range that is flat, uniform and of consistent 5mm thickness (also available in 7mm when required).

Roofing contractor: DM Roofing

Underwood House, Craigie is a 19th century Grade B listed residential property in Dundonald Ayrshire. The private property was purchased in 2017 and the current owners sought to undertake a full refurbishment to the four-storey home with cellar.

The 500m2 pitched roof features a half turret with six dormers and sweeping/curved valley details. It had been refurbished over time and the property was habitable.

However, as an extension had been built, the property was tiled in two types of Welsh slate, which in turn, didn’t provide the desired uniform appearance of traditional Scottish Ballachulish slate, as is used in vernacular architecture of the area.

SIGA 120 meets HES requirements

Underwood House Case Study Website Inset Image 4After discussions with Historic Environmental Scotland (HES), the architects specified SIGA 120 random diminishing slate from SIG’s 120 Excellence range as it is now widely considered as a credible alternative to some historic Scottish quarries, and as such, has been used on many listed buildings.

It also provides a readily-available alternative to long-discontinued domestic British slates. It’s a close match for texture, colour and size to Ballachulish Slate, without the slightest compromise on quality; a superlative quality stone with very low wastage.

The Excellence range comes with a 75-year extended warranty when fitted in line with BS 5534 code of practice for Slating and Tiling.

UK Roofing Award winning, DM Roofing (DMR) of Kilmarnock which specialises in listed and historic buildings was chosen by main contractors, G Middleton of East Kilbride for the full refurbishment of all roofs to the property. […]
