The same is true for beams like structural ridge beams and center girders.

Continuing on from part 3. The other is just used to support the trusses. Let s consider a basic gable wood roof framing design. You can t beat sawn lumber for most small window headers but as spans and loads increase stronger materials are a better choice.

Too often builders gang together 2 inch dimension lumber to support roof and floor loads without considering other options. A great deal depends on the pitch of the roof.

Here we have a wood framed gable roof.
