Here we have a wood framed gable roof.
Putting a new roof on warped support beams.
This effectively creates channels on both sides of the beam ensuring that you ll be able to lift the beam upward without fear that it will slip off the ledgers.
Attach the horizontal beam by using a nail gun.
Measure from the floor to the beam to monitor the beam s rise.
Long story short it is possible to put steel on this type of roof but have a contractor look at it first and make sure you are not just hiding a disaster waiting to happen.
The image below shows a cross section of our simple 12 x 13 house from the joist span tables section of this tutorial.
Raise the house beam by pumping the hydraulic jack very slowly using short strokes.
If required you will need to use something that forces up the roof while you are working the new beams into the right place and fastening them securely.
It can be nailed temporarily to each truss as the next truss is put in place.
Usually trusses are put 24 inches apart.
Make a cutting on one of the sides of the horizontal roof beam on an angle.
Nail or screw these cleats into place so that they box in the beam.
Floor beam span tables of residential structural design we will now look at roof rafter and beam design.
Place the jack back underneath the beam but this time under the iron piece.
Have an assistant simultaneously raise the shoring post as tight as possible against the beam to provide backup load support.
It is important to choose brass screws since brass will not rust until iron screws.
Raise it no more than 1 2 to 1 in.
Remove the jack quickly and set the iron onto the entire beam.
The pitch of the toof is significantly increased to provide additional strength and durability as well as providing a better internal space.
It s time to start restoring the structure marking an important moment in the house s history.
When all the trusses are installed and the first row of decking is on this brace is removed.
Total to release the weight from each post.
Let s consider a basic gable wood roof framing design.
To hold them up until the decking of the roof is placed on top a 12 foot 1 inch by 4 inch piece of lumber is used.
With the beam resting on the beam ledgers attach a pair of 2x4 side cleats to the king studs at both ends of the beam.
Sometimes a sagging roof line can be fixed with a few new joists and osb sheeting but sometimes it is cheaper and smarter to remove the entire roof and replace with engineered trusses.
Continuing on from part 3.
After that to make it flush with the roof of the existing house cut the two outer rafters.
Step 2 the conservatory roof is carefully removed leaving only the windows doors and and brickwork in place.
Drive the remaining carriage bolts into the two by six rafter and tighten them all up.
Make sure that while you work you push the roof upwards.
