Changing Conservatory Roof

Changing Conservatory Roof

Hi There, can you please tell me if I need a building warrant to cover changing an existing conservatory roof (polycarbonate) to a fully insulated one with lightweight Metrotiles. The conservatory is 10 years old with all the necessary paperwork in place for it i.e. building warrant, sign off etc. I have already signed the deal with a company to fit the roof before I realised that the existing building warrant would not cover the changes. The proposed schedule for works to start is September. If I can find out if I need a building warrant before hand then I can ensure the company takes care of this as I was told (by them) that I would most likely not need one. Many thanks.

    Hi Robert.

    Is this a multi foil insulation being applied to the inside face of your conservatory roof?

    The building regulation lists works exempt from building regulations as,

    “Any work associated with thermal insulating material to or within a wall, ceiling, roof or floor.”

    With the exception if the insulated material is located externally.

    As the existing roof is polycarbonate (assumed that it lets light through) covering this over changes the type of roof. Therefore a warrant would be required.

    Thanks for using Do I Need Permission.

    We have had this type of work completed, and have been told by building control that we require a warrant as this is now a sunroom as the ceiling is not 75% clear by area.
