Alpine truss designs are engineered to meet specific span configuration and load conditions. As the name implies this roof appears flat in structure although it is always pitched at a wider angle to allow water runoff.

This method allows for greater energy efficiency. A standard rule of thumb is the cathedral roof pitch can be up to one half of the roof pitch. It is usually used for roof construction some common trusses are named in accordance with their web configuration. The raised heel roof truss reduces.
