We used the Metrotile conservatory roofing https://www.metrotile.co.uk/building-types/conservatories/ guide when planning our home extension. The section about energy efficiency caught our attention — it’s amazing how much warmer the space is now. The roof looks like part of the original house, not an add-on. The 40-year guarantee and modern look sealed the deal for us. The site gave us all the details before we even spoke to a contractor.
