How to Frame a Double Shed Roof with Wall in the Middle
The video begins with explaining the different block types that will be used for the project. There are two types of blocks mentioned in the video. The first block is designed to be aesthetically pleasing and can be painted or finished on the outside.
The second type of block is preferred by engineers and is shaped so that it can be easily nailed. Fire blocks are also crucial for this project. They are installed to prevent fire from spreading through the house. They work by preventing oxygen from reaching the fire and slowing down the burn rate.
The video then dives into the framing process. The first step involves creating a wall that will be a little shorter than the other walls. On top of this short wall, a ledger will be nailed. Rafters will then be attached to the ledger and toenailed in for additional support.
Next, the video explains how to frame the upper part of the roof. Here, a taller wall is constructed, and fire blocks are installed within the wall. Similar to the shorter wall, a ledger is nailed to the top of the taller wall, and rafters are attached and toenailed to the ledger.
The video then goes over an alternative way to frame the roof. In this second design, a post and beam are used to support the wall in the middle instead of a short wall. A footing is required to support the post. The beam sits on top of the post and supports the wall.
The wall, in turn, supports the rafters on the upper area. Rafters can be toenailed into the beam for support. Hangers can also be used for additional support. The size of the beam will depend on the span it needs to cover. For example, a 16-foot beam will require a larger size than a beam with a post in the middle supporting it.
