Roof With 2 Different Pitch

Joining two roofs of different pitches blind valleys simplify framing.

Roof with 2 different pitch.

The roof rests on two bearing walls with two sloping walls meeting in the middle to form an m shape. The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7. A sketchup model helps clarify how various rafters and framing components are assembled in an off angle hip and valley configuration. Explore framing complexities that result when roofs of two different pitches intersect.

Where the porch roof extended over the shed roof we installed a 2x6 ridge that ran from the top of the. To keep the porch roof framing as simple as possible we installed a structural ridge. 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. A pitch of 2 12 is the minimum pitch for shingles made of asphalt so your roof just barely makes the cut off for one of the most popular roofing material options.

Lining up the fascia. Look at figure 2a which shows the two differently pitched common rafters. 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. Learn more about off angle roof framing.

Managing a hip roof with two different pitches 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. So 9 5 8 12 is the secondary roof pitch. Central guttering runs between the two pitches to stop any snow or rain building up in the winter season. Resilient asphalt shingles lie much flatter to the substrate than slate tile and concrete which keeps water from being easily blown under them.

This technique is beneficial particularly in home expansion.
