Start by installing self stick underlayment on the decking.
How to roof an a frame.
This can be done either with many pairs of hands or with the assistance of a crane.
Trusses are often spaced 12 16 or 24 inches apart.
This process is much easier with two people.
Then gather your measurements by calculating the run rise and length of each rafter segment in feet and the pitch of your roof in inches.
The high end of the rafter sits on or attaches to a ledger plate attached to the existing wall.
The resulting angle forms the pitch of the roof.
Wondering how to build the structure of your roof.
Rafters are placed to the top plate of the second floor and joined to the ridge beam.
This video covers one of the most exciting parts of roof framing installing rafters.
Roof valleys channel a lot of water so they need extra protection.
Once the ridge beam has been positioned in place and supported by roof framing members you can determine the placement of a rafter by measuring down from the top of the beam y height and making a mark on the beam.
You can determine the length of a common rafter using either of two easy methods.
Like wall studs and floor joists rafters and trusses are spaced every 16 or 24 inches from center to center.
The rafters are usually positioned directly above the wall studs.
Next use these calculations to determine how many rafters you ll need for your roof and cut them to size.
Most roofs utilize 16 inch spacings for strength and rigidity.
We will go over raft.
Use ladders or scaffolding if you are building the roof onto a building that is still a frame.
The framing of a basic gable roof is based on a right angle triangle and the various roof framing components fit the triangle.
Lean to shed roof framing a lean to roof just means it s attached to an existing structure.
Cut the flashing back to the peak along each crease.
The lower end is done the same way a skillion or shed roof is.
And the line length measurement from the roof peak to the building wall is the hypotenuse.
The rise or height of the roof at its peak is the altitude of the triangle.
To frame a roof start by choosing a roof style like a frame or gabled.
The run or half the building span is the base of the triangle.
Stick framing combines roof rafters with ceiling joists.
