Yes, they are. We take care of the building regulations on your behalf and provide you with the relevant paperwork. If you wish for your Tiled roof to comply with building control regulations there will be requirements for extra PIR insulation and fees for building control via JHAI building control, please ask your representative for an additional cost. Please note few Local authorities in England and Wales don’t currently consider conservatory roofs replacements to come under Building Regulations, if in doubt please contact your local authority or speak with a member at Greenoak Concept & Design for further advice.
