Flat Roofs

This unusual seven-sided balcony terrace area in Bude in North Cornwall was leaking and in need in refurbishment.

This terrace refurb case study again demonstrates how flexible the polymer system can be and how well its jointless and seamless "perfect forming" nature is suited to sites that might prove challenging for many other systems.

This terrace refurb case study demonstrates just how flexible the polymer system can be. This smart property in Lexham Gardens in South Kensington, London W8, had several exterior areas showing significant signs of degradation and pooling. These ranged from very narrow areas fronting the property to a patio seating area providing usable outdoor space.

This roof terrace in Radlett near Watford in Hertfordshire, North London received a brand new polymer treatment during the winter months. As the photo shows, the terrace / balcony is subtly tapered, allowing for rainwater run-off and drainage.

This building in Bude in North Cornwall needed its roof converted from Cold Roof to Warm Roof. This was however a trickier than usual job as the existing roof needed to remain entirely in situ and there was a very large area requiring insulation.

The photos above show the state the roof was in prior to work commencing, with the last 4 pictures showing the completed installation.

This flat roof in Waunfawr, Aberystwith in Ceredigion (West Wales) required warm roof insulation to comply with government U-values regarding (a measure of the rate of heat transfer across a surface). Roof "obstacles" and detailing are no problem at all for the polymer system but in this case were sparse, being limited primarily to chimney venting.

The abutting roof on this property on St Davids Road in Aberystwth needed full insulation to comply with governmental "U-Value" standards. "Warm roofs" differ from cold roofs in that they do not require ventilation and the insulation is placed above, rather than between the joists. They are required by law on certain roof types such as where people will live and/or work beneath or, as here, where an extension meets the main roof (see warm roof section for more on this).

This flat roof in west Wales needed proper ventilation to resolve moisture build up, a common problem for cold roofs (explained here in relation to warm roofing) especially in such notoriously rainy areas of the UK.

This roof in Preston, Lancashire needed an alternative to its existing lead panel roofing. The work extended over relatively small areas on two levels, including an irregularly shaped area to the fore. 

This was both quick and straightforward for the polymer system - also known as "liquid lead" it easily coated the problem areas, providing a fully waterproof and weatherproof jointless, seamless new roof for the area in only a few hours.

This seaside property in Borth (Ynyslas) on the west coast of Cerdigion in Wales really put the polymer system through its paces, using the system's incredible versatility to achieve multiple ends that ultimately involved not just roofs but walls and windows.

The house now has a polymer lined balcony, converted from an existing roof area, a fully sealed and watertight Dorma window, and coated walls, protecting it from the worst of the Welsh weather and sea winds for many years to come.

This rubber clad plywood on this balcony flat roof in Flint, North Wales had failed, deteriorating in several places. This was the third time the roof had had to be replaced in the space of 12 years and the owner was now seeking alternatives. As the pictures show, the flat roof was over a hollow storage area which adjoined the house. A new substrate was required along with a waterproof covering.
