Riverside, one of the leading social housing and
regeneration organisations in England, has re-roofed 404
properties on the Botcherby Estate in Carlisle using
Sandtoft’s Olympus, Rivius and Modula clay roof tiles. The
new roofs form part of a refurbishment which has seen the
external envelope of each house transformed with new
fascias, gutters, rendered panels and canopies.
Built around 75 years’ ago, the houses are located on an
estate which has changed dramatically over the last few
years as a result of a multi million pound neighbourhood
revitalisation investment by Riverside. The properties
featuring Sandtoft’s products are spread over three
different streets in Botcherby and originally featured
Gaelic clay tiles.
As well as supplying roof tiles, Sandtoft worked closely
with the contractors and Riverside to develop a roofing
specification that required no mortar. This included the use
of dry valleys and bonding gutters as well as Koratech, a
vapour permeable membrane which unlike traditional Bitumen
underlay, helps to prevent condensation in the roof space.
John Robinson, Asset Investment Manager from Riverside said:
“We were considering reusing the Gaelic tiles until we were
shown the Olympus clay double pantile and realised the cost
savings that could be achieved. The dry fixing system was
also a major benefit as it could be fitted in any weather
ensuring that the construction programme wasn’t delayed.
“We used the Olympus clay double pantile on one of the
streets and the Modula and the Rivius on a further two
roads. Overall, the appearance of the properties in all
three areas is very pleasing and the estate looks
considerably better and more modern. We have received
numerous compliments about the estate which has changed from
a place where houses were difficult to let, to one which has
a waiting list of potential tenants.
The Olympus, Rivius and Modula tiles are part of Sandtoft’s
New Generation range. Each tile in the range has been
designed to make a natural clay roof more affordable as a
result of an innovative design that significantly reduces
installation costs. Approximately 10 tiles are required per
square metre, resulting in a covering capacity that matches
the largest concrete tiles. In addition, an open gauge means
there is no need for cutting at the eaves and ridge making
the tiles quick and easy to lay.
Andrew Lawton, Sandtoft’s sales director added: “The
Botcherby project was an excellent opportunity for us to
showcase the variety and adaptability of our New Generation
range and dry system capability. Working in close
partnership with Riverside we were able to dramatically
reduce their costs and create a long-term solution with a
lasting impression.”
