Roof Refurbishment – Laura Ashley, Bromley
Following a site survey, Laura Ashley in Bromley High Street, required a new high performance felt membrane solution. A survey of the main and lower roof areas was undertaken by Proteus Waterproofing. The existing felts were found to be tired and coming to the end of their useful life. Core samples taken found only a small amount of moisture and the existing roof insulation met current Building Regulations, Part L thermal requirements.
Due to a fully functioning shop under the refurbishment roof areas, noise and odour needed to be kept to a minimum. Once the felt repairs were complete, a Proteus Pro-Felt® Dispersion Underlay was first installed to allow any entrapped moisture in the existing build-up, to expand and move, without blistering the new overlay system. Proteus Pro-Felt® Ultima Plus black mineral capsheet was then installed to complete the overlay system, providing a 20-year guarantee and supported by a BBA Certificate stating a minimum 30 years before a first major maintenance is required.
When working in a busy area, safety is always of utmost importance, as well as minimising disruption or suspension of existing services to the building during the works. Proteus Waterproofing worked in close partnership with licensed contractor to successfully deliver the project to a very high standard, including technical manager inspections throughout the project.
Proteus Pro-Felt® Ultima Plus is a High Performance multi-layer bituminous membrane system, tested to perform in extreme temperatures and weather conditions. This membrane is impervious to water and will achieve a weather-tight roof.
It has class leading modified bitumen content which allows the flexible membrane to move with the building and ensure long term durability and performance which is certified by the BBA to be in excess of 30years. All Proteus Waterproofing specifications promote fire safe installation methods conforming to the industry lead Safe2Torch guidelines.
