Roofshield® revisited: Southgate, Bath

Roofshield at Southgate in Bath

You would expect the beautiful buildings in the city of Bath, designated by UNESCO as a World Heritage Site, to be protected by one of the highest-performing roofing membrane solutions on the market.

Indeed they are: by one of the A Proctor Group’s leading products, Roofshield, which was developed 20 years ago in response to problems caused by the requirements of the UK’s demand for cold-pitched roof construction.

Today, trusted by architects, developers and contractors, the Roofshield brand is synonymous with second-to-none quality, providing a pitched roof underlay which is both air- and vapour-permeable.

SouthGate, a retail, mixed-use development within the Bath Conservation Area, first opened its doors in 2009 – 2010, following a development led by architects Chapman Taylor, and with the Roofshield membrane fitted to the roofs of the shopping centre.

Some ten years on and Roofshield is still performing equally as well today as the day it was first installed.

The A. Proctor Group caught up with Andy King, Managing Director of the specialist roofing contractor A.L. King Roofing, who was appointed to carry out roofing works on SouthGate.

Andy recalled: “A key requirement in this sensitive project was to deal with the challenge of all the ventilation requirements for a wide variety of roof slopes, with differing eaves and ridge details.”

As the project was a mixture of commercial and residential properties, there would be differing levels of moisture and vapour control requirements. Therefore, in agreement with the principle contractor, it was decided to use Roofshield.

The high-performance air permeability of Roofshield means that it will allow even very complex pitched roofs to breathe, without the need for air gaps or secondary venting.

Our experience on this project is that Roofshield has performed exactly as expected, with no condensation problems despite the diversity of uses of the buildings.
