I have a small lean-to type conservatory, built around 2000, and because it gets too hot in summer and too cold in winter I would like to change the roof (and to stop it springing leaks!). I have seen these new roofs which stop the conservatory getting too hot etc., and wonder if anyone can advise what I should be looking for when I enquire of suppliers. The roof is about 9' x 10'. I will have to get someone in to do it, but need to know what is the best buy and so on. Any help would be most appreciated. Thank you. And a Happy New Year to all. Dee.
