I am building a simple pool house with a large overhang roof. Main issue I have is figuring out what beam size and span I need to support the roof properly. Key Features:
- Total Roof width: 29ft
- Distance between Posts: 27ft (center to center)
- Roof Type: 2x12wood with 2 by 12 Pitch (~10degrees)
- Location: Ontario, Canada (snow load)
I was told I need a 10″ Steel Beam but have some questions:
- What specific size of beam?
- Does it span the full width of the roof or can it stop at the posts?
- Do I need LVL or steel beams going from cross-beam to the shed that is 10ft distance or can the 2×12 carry that load/distance?

not trying to be mean, but this is precisely what engineers are for. You want to span a long way, with one member sitting on two posts, and subject it to wind and snow loads. It needs to be properly sized and spec'd in relation to your support structure. You should be able to take your sketch to an engineer and have them size things and specify how to make the attachments, and find a qualified one that won't be too expensive.
