The installation process

For replacement roofs, the existing glass and rafters are removed and in their place exclusive GRP beams are installed to the existing frame - for new builds the rafters are added to to the finished wall or door system. Under these rafters the advanced Leka sheets are added, these sheets are 100% waterproof and have unique thermal qualities, whilst allowing a traditional plaster finish to paint on the interior surface.

Insulated Celotex sheets are fitted with a 15mm gap from the Leka sheets and provide high value thermal efficiency, with load bearing and insulated outer sheets installed on top. Finally a high quality roofing finish is added, with either a Tapco or Metrotile in a range of colour options offering a classic roof look that is consistent to existing roofing finishes.
