Valley joining two roofs with different pitches.

Would like to know how you cut the valley rafter when you have two different pitches on intersecting roofs. Joining two roofs with different pitches is a method that exists in the building and construction world. It is possible to join different roof pitches but only if you use lead in the valley and ridge hip tiles on the hips. We re going to install it over top of the panels that have already been installed on the lower slope.

3 12 and 6 12 is 4 5 17. We ll start with the knowledge that the main roof has an 8 12 pitch. Position the flashing between the two roof pitches. Place the 2 by 4 inch piece of lumber along the center of the flashing.

The other is to get the fascias to line up. The only real problem arises if you have plain tiles the small 10 5 x 6 5 inch on the roof. I have only built one roof where a hip was joining two different pitch roofs at the corner of a house. John carroll takes the mystery out of it.

At the low end of the valley the subfascias of the two roofs are mitered with a block filling in the roof framing. Joining these two roofs poses two main challenges. This technique is beneficial particularly in home expansion. One is getting the two differently pitched planes to meet at the hip or valley rafter.

I was taught to split the different pitches thus coming up with the hip pitch. Differing pitch valley vaulted. I have done it before using the old tried and true string method but there must be another way. Am on a job at the minute with as per title different pitch roofs connecting and vaulted ceiling.

If by any chance right now you are looking for the information about how to join two roofs if they have different pitches here we will share all the information we know with. Slide the right edge of the flashing under the highest roof pitch. Unequal pitch roof intersections have always been head scratchers. This allows water to flow off the upper panels out over the trim onto the lower panels and exits the roof at the eaves.

How does the 17 12 idea fit in here. Sometimes valley tiles and bonnet hips are used with these but it must be the same. The problem has always been the height the rafter sits off the top plate to line up with both roof planes. The piece that allows us to join the two different slopes is the pitch transition trim.

Joining two roofs of different pitches. This is the normal method for most tiles anyway.
