Trussed Rafter Roof Shapes
The table below shows some of the most common roof shapes, although the majority of roofs designed today tend to incorporate combinations of multiple roof shapes.
The Port Logan Self Build (3D image on right) for example is a combination of different roof shapes. The rear of the property, bottom left side, has a hexagonal hip end over a garden room, next is an attic roof including one dormer, together with a raised tie T-intersection with dormers, and a small hip over the front door.

Both the roof layout/plan and interactive 3D model are PDF files, they can be viewed by clicking on the image.
