Patio roof support load bearing.

The basic idea behind the structural design of patio covers is to safely transfer weight from the top of the patio cover to the foundation. The tables below give maximum spans for rafters and beams. This will hold the weight of the porch roof while replacing the beam. Move the braces into place on top of the bottle jacks image 3 then raise them till they support the roof.

Maximum rafter spans for a patio roof. The chain of load distribution begins at the roof covering material which exerts force on the cover s ceiling joists. Join the support beam and wood load bearing post by toenailing them together and attaching two metal t braces to opposite sides of the beam with galvanized 10d box nails. Once that s done and the support strapping is reinstalled on all gas electric plumbing and heating lines you ll have the satisfaction of completing a job that will last for the life of the house.

With the old beam uncovered the temporary beam can be placed on the braces you ve made images 1 and 2. For heavy roofs or in areas with substantial snowfall or winds call your local building department for code requirements.
