Our Best-Selling Conservation Roof Windows

Conservation roof windows are a traditional style window that seamlessly blend into all old building roofs thanks to their black exterior profiles and the Victorian cast iron inspired glazing bar that runs down the middle of the window. These roof windows are perfect for traditional buildings like churches, barn conversions or just any roof that is darkly-tiled. 

If you live in a conservation area, you may be required to install a conservation roof window rather than a normal roof window. So, keep reading to gather an understanding of our best-selling windows! Or if you just fancy something a little different then that's fine, you can have one too!

Please note, this roof window is only suitable for roofs with a 15° - 60° roof pitch - but on the plus side, it gives you easy access to the roof!
