Home is the dream object for everyone and there is nothing important like home. When you’ve found your dream house which fits your housing budget, the desire to purchase it will be inevitable.
However, after the purchase is done, you might notice something on top needs an extra touch. A little renovation is ongoing, but you have no proper knowledge in joining two roofs with different pitches.

Now, what to do? Searching for the answers on the net can be helpful. So, get ready to jot down the steps of fixing your roofs with different pitches.
How To Joining Two Roofs with Different Pitches
If you’re new in this, roof pitch is the definition used to show the steepness of the roof. The pitch itself is a ratio of the rise of the roof and the span of it. It is commonly shown as a fraction number like 5/12, 10/12, etc.
The higher the numerator is, then the steeper the roof will be. Well, here’s what you need for joining two roofs with different heights. Things you will need:
- Working gloves
- Measuring tape
- Permanent marker
- Circular saw
- Metal snips
- Metal screws
- 2-by-4 and 1-by-1 lumber
- Butyl caulking
- 12-inch aluminum flashing
- Shingle remover
- Roofing nails
- Metal snips
- First, determine the roof areas that you want to join. Put your gloves on then remove the shingles and underlayments on both edges for approximately 6-8 inches using a shingle remover.
- Measure the edges of cleaned-edges. Add 12 inches to the measurement result. Your flashing length is measured this way.
- Using your metal snips, cut down the flashing after matching it with the measurement.
- Next, put the flashing between two roof pitches. This is where joining two pitched roofs together starts. Slide the flashing under the highest roof pitch first and followed by the lower pitch. To bend the flashing, use a 2-by-4 lumber by pressing it gently until the flashing gets bent and matches the slope. Put the lumber aside.
- For the next step of joining two roofs with different pitches, 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, followed by placing the second piece under the lower roof.
- Make sure to keep 1-by-1 lumber pieces in their place, and drop some butyl caulker along. Let it dry.
- 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.
- Make it neat by folding the flashing edges around the roof’s edges and along the bottom of the eave. Attach the folds using metal screws. Before joining two roofs with different pitches, you can temporarily remove the eaves’ trim and replacing it after completing joining the roofs.
- As a final touch, cover the flashing with shingles. The shingles may overlap to provide full coverage for the combined roof. The roof is now combined and you’re now good to go.
Working on a roof can bring up some danger due to its height and uneven surfaces. Therefore, consider to do several surveys and exercises first before joining two roofs with different pitches.
That way, you can get used to walk on the roofing surface, as well as adapting yourself well to work in such condition. Always use gloves and goggles to keep your safety.
