The apex of a roof can be given a sharp or soft outline by using different ridge profiles. The most commonly used is the half round ridge and a similar soft appearance is obtained with a hog back ridge. An angle ridge provides a sharp apex and this in turn can be broken up by using capped angle ridges or a special ornamental profile. Ridges are handmade at our Works in the UK - 300mm in length.
