Can a 4X12 Cedar Beam support a Solid roof patio cover over 20 ft?

A 4x12 cedar beam can support a solid roof patio cover over 20 feet, but its load-bearing capacity depends on various factors, including the beam's span, the type of roof material, local building codes, and the spacing of supporting posts. Typically, for longer spans, larger beams or additional supports may be required to ensure structural integrity and safety. It's advisable to consult a structural engineer or a qualified builder to assess the specific requirements for your project.
