One of the most important parts of building a sturdy roof is the initial roof framing plan. Roof framing simply describes how a group of rafters and beams are fitted or joined together in order to provide support samplee the roof covering.

In order to do roof framing properly, it is important to understand the unique shape and dimensions of your roof, frraming these will greatly impact the geometry of the roof frame. For example, in the case of stick framing, you will use ordinary lumber for your framnig and beams, and then build the frame one beam at a time. In wood roof framing plan sample case of truss wood roof framing plan sample, you will use pre-made wood roof framing plan sample wood pieces to build the roof frame.

The most common of these roof frming include the following: gable, hipped, mansard, gambrel and flat. Sometimes you see a combination of two or more styles used on the same roof, such as wood roof framing plan sample case of a hipped roof with a gabled dormer.

So, wooe you can probably imagine, each different type of roof will require a different type of samle frame. Generally speaking, the simpler the roof type, the easier it is to build a roof frame to support it. However, even a relatively wood roof framing plan sample roof type — such as the gabled roof — can be made more complex with the use of overhangs, hips and dormers. If you think about this plam from a purely geometrical perspective, you can understand why this makes sense: each little twist or variation on a common triangle shape i.

Also, if you are planning fgaming making additions or modifications to your roof at a later date, it is preferable to use the stick framing approach. As noted earlier, roof framing is really all about getting the geometry of your roof correct.

Thus, it is important to understand how each of the following calculations wood roof framing plan sample impact the roof framing process:. Span refers to the full measurement across the top of your building, from one exterior wall to the other exterior wall.

Once you know the span, you can then calculate the rise. The rise is the measurement from the center point of the span to the top of the roof. If you are thinking in terms of geometry and triangles, as you must when you take on a roof framing project, then the line length is simply the hypotenuse of rlof triangle defined by the rise and the plaj.

The final calculation, the pitch, can be understood as the amount of angle or slope that the roof has. This 12 corresponds to 12 inches, or 1 foot. Pitch can be either shallow or steep, depending on the needs of the roof.

For example, in areas of the country where snowfall is abundant, it makes sense to create a steeper pitch in order to make snow removal easier. If you are using the stick framing approach, you framiing now need to spend time measuring and cutting the rafters based on the calculations you just made. There are several different methods for doing this, but by far, the most popular method uses the traditional framing square. Using the traditional framing square and the calculations from earlier, you can lay out the rafters appropriately.

Each of these cuts determines how two different pieces of wood will interlock and fit together to form one sturdy frame. As you can see, the initial plan for framing your roof needs to take into account several key variables, such as the shape of the roof and any relevant community building codes.

You will then have to choose between two very different types of roof framing stick framing vs. The goal, of course, is for every part of your roof frame to fit together perfectly, such that you have the perfect support for your new roof.
