A 90m2 warm roof new build extension with 3 skylights and a 25m2 terrace with two adjoining gutters.

On the main roof, we installed a VCL followed by mechanically fixed tapered insulation to ply from 150mm to 120mm to achieve the desired U- values and correct falls. To finish we installed an Evalon VSK self-adhered membrane, coming up and over the parapet which is to be finished with bespoke aluminium capping. Skylights were finished in VSK, three of which will have skylights installed with the other being left open and finished with bespoke capping. Three pre-formed vertical internal outlets were installed, these are discreet and leave the roof with a neat and tidy finish.

The terrace was a 25m2 cold roof with a surrounding parapet with VSK brought up and over – this will be finished with bespoke capping. The two adjoining 9m hidden gutters and terrace were waterproofed by fully adhering Evalon VSK straight to ply with a 20-year warranty issued.
