Roof With 2 Different Pitch

So 9 5 8 12 is the secondary roof pitch.

Roof with 2 different pitch.

Roof pitch ratio and angles. The meaning of the ratio is easier to understand if you take a look at the picture above. Managing a hip roof with two different pitches. As an example please take a look at the 1 12 ratio image.

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. Whilst it may sound ridiculous today they are used quite a lot these days to make a home look a bit more unique than others on the market. The way to read it is like this.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Look at figure 2a which shows the two differently pitched common rafters. Also different architectural styles will use the same type of roof. Blind valleys simplify framing.

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. 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.
