Roof With 2 Different Pitch

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

Roof with 2 different pitch.

Look at figure 2a which shows the two differently pitched common rafters. Using a pitch measuring tool that i d made we also determined that the exact pitch of the shed roof was 3 1 2 in 12. Also different architectural styles will use the same type of roof. It shows the image of roof pitch ratios as well as the standard angles resulted.

Lining up the fascia. Managing a hip roof with two different pitches. Roof pitch ratio and angles. Intricate roofs have many parts that incorporate several of the basic roof designs such as a gable roof sitting atop a gambrel or variations of the gable valley roof design using one or a variety of different types of roof trusses also see our very detailed diagrams showing the different parts of a roof truss.

One thing that has become far more popular in recent years is the usage of hip roofs that have an alternative pitch at one side to the other. The meaning of the ratio is easier to understand if you take a look at the picture above. As an example please take a look at the 1 12 ratio image. So 9 5 8 12 is the secondary roof pitch.

It would seem that lining up the fascias and cornices so you have equal overhangs on both pitches would be impossible since the rafters of the two roofs extend beyond the plate at different angles. To keep the porch roof framing as simple as possible we installed a structural ridge supported by posts at each end with the common rafters landing on top of the ridge. The way to read it is like this.
