Replace Cracked Roof Support

Each side of the iron should be four inches wide with the entire piece being at least two feet long.

Replace cracked roof support.

Over time roof rafters can wear crack or rot and replacements may be in order. The first thing you need to do is to assess the damage. This will give some added strength and take care of any cracks in the wood itself. Rafter and joist systems are made up of two pieces of wood that run directly beneath the roofing surface and give it its shape while joists bridge the gap between the two rafter ends and support the whole thing.

If the roof truss has a small crack you will be using the two wooden boards to patch it up but if the crack is much more severe you should use the steel plates because they offer much stronger support to the damaged truss. This will hold the weight of the porch roof while replacing the beam. At some point the roof drain clogged the roof turned into a swimming pool and this ridge board beam cracked tore in the middle.

Drill holes in angle iron to keep the rafter from buckling again you will need to secure it with a piece of 1 2 inch angle iron. A severely arched bulged cracked or sagging floor joist can only get worse over time eventually deforming the floor above it. These will serve as patches to be installed on each side of the broken roof truss. Move the braces into place on top of the bottle jacks image 3 then raise them till they support the roof.

Clean the surface of the tile with a rag soaked. Place the temporary beam with the old beam uncovered the temporary beam can be placed on the braces you ve made images 1 and 2. Rafter can usually be repaired or replaced from underneath without excess trouble broken ridge pole would normally be spliced with metal repair plates or sistered unless rotten because not feasible to replace it with roof in place to replace economically requires roof be opened up at the ridge at least. Correcting a problem joist is an easy repair and makes a big difference in your finished floor.

Apply it directly on top of the cracked area and push it down into the crack with your finger or a putty knife thus capping the void and the leak. Cut two pieces of lumber 4 feet long for the first phase of the repair.
