New Skylight Installation in a Warm Flat Roof

New Skylight Installation in a Warm Flat Roof

New glass skylights being fixed into new warm flat roof using a liquid roofing system as the waterproofing. The old asphalt roof was used as the vapour control layer (VCL) then 120mm of flat roof insulation was glued and screwed over the top, finished with a liquid roofing system called AH25. The glass skylights were quite big so they had to be craned into position.

    Hi Steven,

    Would like some knowledge from you on a proposal to put a rooflight (1200 * 600) in a new flat roof which will be on a new storey added on to an existing red brick block of flats. The new storey will be metal clad. I do not know what material the new roof will be. Do you have a recommendation what would be the best material for such a roof and what you would not use. Would you personally put a rooflight in a flat roof? The new storey will have a 200mm step between the current building and the proposed top storey.

    The current building is ground, first and second floor with an area per floor of 200 sq m.

    Kind regards.
