Sizing a ridge beam.
A ridge beam is typically made up of several pieces of lumber that are joined together to form a single, solid beam. The size and thickness of a ridge beam depend on the size and weight of the roof that it must support. In modern construction, ridge beams are often made from laminated veneer lumber (LVL), which is stronger than traditional wood

When you are preparing to build a shed roof, you must first engineer the rafters - that is, know the species of wood you will use for the rafters, the nominal size of the rafters (2x6, 2x8, etc.), and the spacing of the rafters. To determine the size of the rafters, using span tables, you need to know three things:
