Insulation can be upgraded or added to your roof if required.


We include all new roofing trims to compliment your new flat roof.


Keeping your house warm

Warm deck roof systems involve fixing Celotex insulation boards to the top of the roof decking this stops the need to remove the decking to insulate between the joists. This also will bring your Flat Roof up to current building regulations. Your existing roof is encapsulated with 120mm (5”) Celotex insulation boards and vapour controlled later. For living areas we will update the insulation to a U vol. of 0.18.
