How To Joining Two Roofs with Different Pitches

If you’re new to this, don’t worry. Here’s a guide to help you through the process, including how to prepare the area and measure the length of the joined area. The pitch itself is a ratio of the rise and span of the roof. It is commonly shown as a fraction number like 5/12, 10/12, etc.

Procedure for Joining Two Roofs

  1. First, identify the areas of the existing roof that you want to join. After putting on your gloves, remove the shingles and underlayments on both edges to a width of about 6-8 inches.
  1. Next, measure the length of the joined area and add 12 inches to this measurement for your flashing material. This extra length ensures adequate coverage for the joint.
  1. Using your metal snips, cut down the flashing after matching it with the measurement.
  1. Common rafters might require adjustment as you place the flashing between the two roof pitches. Start by sliding the flashing under the higher pitch, then the lower. To bend the flashing, gently press a 2-by-4 until it matches the slopes. Set the lumber aside.
  1. For the next step, you need to measure, mark, and cut two pieces of 1-by-1 lumber to work as the edges seals. Just like what you do with the flashing, slide the first piece under the higher roof first, then place the second piece under the lower roof.
  1. Make sure to keep 1-by-1 lumber pieces in their place, and drop some butyl caulker along. Let it dry.
  1. Now, stick the flashing to the roof using metal screws along its four sides. Each screw is spaced around 6 inches. Measure and add it by 1 inch, then cut a piece of underlayment. Slide the underlayment beneath the still-existing shingles and secure the underlayment by nailing it using roofing nails.
  1. Make it neat by folding the flashing edges around the roof’s edges and along the eave’s bottom. Attach the folds using metal screws. Before joining two roofs, you can temporarily remove the eaves’ trim and replace it after joining the roofs.
  1. After joining the two roofs, cover the flashing with shingles for a seamless look. The shingles should overlap to provide full coverage over the combined area. Remember to replace any eave trim you may have removed during the process. With these steps, your existing roof will have a new, unified appearance.

Roof work involves risks due to height and uneven surfaces. It’s wise to conduct multiple surveys and practice sessions before joining two roofs with different pitches. This preparation helps you become familiar with the roofing surface and ensures safer working conditions.

That way, you can get used to walking on the roofing surface and adapt well to work in such a condition. Always use gloves and goggles to keep yourself safe.

Roof work involves certain risks due to height and potential uneven surfaces. Conduct multiple surveys and practice walking on the roof to become familiar with the conditions, enhancing safety. Always wear gloves and goggles for protection.

By following these steps and ensuring precise cuts and secure installations, particularly at the plumb cut and rafter tail, your roof will look unified and stand strong against the elements.
