How to Cut Rafter Tails

Materials and Tools:

- Rafters (Commonly 2x6 or 2x8 lumber)

- Measuring Tape

- Pencil

- Speed Square

- Circular Saw

- Miter Saw (Optional)

- Carpenter's Level

Step 1: Layout:

1. Determine the roof pitch and the desired overhang for the rafter tails.

2. Calculate the length of the rafter tails based on pitch, tail overhang, and rafter length.

3. Mark the cutting line on the top and bottom edges of the rafter using the speed square and pencil.

Step 2: Setting the Miter Saw (or Using a Circular Saw):

1. Use a miter saw to achieve precise cuts, or you can use a circular saw with a straight edge or guide for accurate positioning.

2. Set the miter saw angle to match the roof pitch. If the pitch is 45 degrees, set the saw at 45 degrees.

3. If not using a miter saw, align the rafter on a stable work surface and place a scrap piece of wood next to the cutting line to guide your circular saw.

Step 3: Making the Cut:

1. Wear appropriate safety gear, including eye and ear protection, while operating the saw.

2. Clamp or secure the rafter to prevent movement during cutting.

3. Start the saw, keeping it perpendicular to the rafter.

4. Cut along the marked line, guiding the saw smoothly and steadily.

Step 4: Cleanup and Installation:

1. Sand any rough edges or splinters from the cut.

2. Repeat the process for all the rafter tails.

3. Install the rafter tails onto the roof structure according to the building plans.

Tips for Clean and Accurate Cuts:

- Ensure the saw blade is sharp for clean and precise cuts.

- Practice on scrap wood before cutting actual rafters to get the technique right.

- Double-check measurements and markings before cutting.

- Consider using a carpenter's level or straight edge to ensure the rafter tail is level and straight.

Remember, if you are not confident in your carpentry skills or don't have the necessary tools, it's best to hire a professional roofer or builder to handle the cutting and installation of rafter tails to ensure safety and proper construction practices.
