I am planning to build a porch roof attached to the back of my house. It
will have a trussed roof. The room will be 14' x 14'. I plan to support
this with one end attached to the house and the other two corners
supported by 6 X 6 pressure treated posts.

What I need to know is what size each of the beams spanning the sides
need to be to support the roof. There will be a 16" overhang on each
side. Roof pitch is 4.5/12. Load is 43.3 psf. Length of one side of the
truss is pretty close to 9' so the area of the roof (that each beam will
support) is about 126 sq.ft.. Total load per beam of 5456 lbs

Thanks,


I'd check with the building inspector. Local codes may dictate
something, especially with snow loads in the north or hurricane winds
in the south. .
