How to install temporary roof supports.

If you have space and there s any structure left near the ends the easiest way is to not replace the existing rafters and joists but to sister a second board on the side of each. Vertical shoring against the top chord of the joist is most certainly the least expensive choice. Continue installing porch roof supports. Install another bracket in this position.

These pieces act as the bases that hold the legs of the support beams. I would never install temporary shoring of open web joists on their bottom chord. I did not interpret your question as whether to support the open web joist on their top or bottom chord. Use 2 inch carriage bolts to secure the posts to the mounting brackets.

The ideal height of such beams should be 2 10 foot longer than the distance between the roof and the ground. Stand a post up in the bracket and hold a level on its side. The temporary support that you use will need to have a firm footing in order to hold up the weight. If the ground area is hard and difficult to penetrate then you can go for an alternate solution.

For a perpendicular support you should use square pieces of 3 4 inch plywood or other scraps of wood that are at least 10 inches wide. Once both of the brackets are secured set a post into them. Place the wood on the floor or ground and hold in place with small screws. Use several bolts at the ends of the wider lumber 7x2.

Bring in the temporary beams and install them in place. Attaching the two with bolts every foot or two 50 cm.
