What is the length of the hip triangle?
The length of the run of the hip (per foot run) is the diagonal or SQR (1 + (R1/R2)squared). This simplifies to (SQR (R2^2+R1^2))/R2.
Does a hip jack fit on the 6/12 side?
So if you make the plumb cut on the hip 6/12, it should fit nicely.Here's something really unusual.Look at the drawing. If you had to put in a hip jack on the 6/12 side of the hip, it would have to run from the ridge to the hip ( like a valley jack), not from the plate to the hip, as a normal hip jack would.
What is the unit run of a hip roof?
Unit run of the hip. In a hip roof with equal pitches, the unit run of a hip or valley rafter is 17 inches for every 12 inches of run in the main roof. For example, in an equal hip roof with an 8 / 12 pitch, the pitch of the hip rafter would be 8 / 17.
How far up the ground should you nail a hip rafter?
Before you nail up the hip rafter, be sure to lay out the position of the jack rafters. It’s a lot easier on the ground than 20 feet in the air.
What is the difference between a valley and a hip?
The main difference between the two is that valley rafters sit on inside corners, while hip rafters sit on the outside corners. Each roof will be slightly different.
How high is a fascia overhang?
The overhang is 16 inches (measured horizontally), and the fascia runs at a continuous height around the entire house. Joining these two roofs poses two main challenges: One is getting the two differently pitched planes to meet at the hip (or valley) rafter. The other is to get the fascias to line up.
How far to step off the hip?
Take the run of the main roof (9 feet), and using your square and the pitch of the hip in relationship to the main roof — 8 inches and 15 5/8 inches — step off this distance in the conventional manner.
Blind Valleys Simplify Framing
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. After installing the rafters, we still had to extend the porch roof back over the shed roof, creating a valley on either side.
Ridge and Jacks
Where the porch roof extended over the shed roof, we installed a 2x6 ridge that ran from the top of the dropped structural ridge to the apex of the sleepers. To scribe the angle, we placed a length of stock on top of the rafter peaks and leveled it across, using a scrap block to trace the angle.
Creating a Valley at the Eaves
Next we worked on the valley at the lower part of the roof. The bottom of our blind valley was about 30 inches short of the bottom of the porch roof, so we extended the line of the valley down to the edge of the new roof.
What is roof pitch?
If you’re new to this, roof pitch is the definition used to show the roof’s steepness. 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.
Is it dangerous to work on a roof?

That way, you can get used to walking on the roofing surface and adapt yourself well to work in such a condition.
Can you join two roofs with different pitches?

What is a half hip roof?

Getting Oriented
Lining Up The Fascia
- Look at Figure 2A, which shows the two differently pitched common rafters. 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. But it’s really not that tough. Making the fascia meet.To keep the overhang ...
Finding The Pitch of The Hip
- Once you’ve temporarily supported the ridges with a few common rafters, you can lay out the hip rafter. I do the layout on a sheet of plywood. Using one corner, I start by drawing the angle of the hip and then develop this line into a fullsized plan view of the roof corner. From this drawing I can pull exact measurements for my bevel cuts. Hip angle. Using the framing square’s 12th scale, fin…
Laying Out The Hip
- Working on the plywood drawing, next snap lines to define the soffit overhang, fascia, and wall framingat full scale, as shown in Figure 3C. Locate the centerline of the hip rafter not at the corner of the plates, but at the corner of the two intersecting fascia boards. Extend this centerline back to and beyond the wall plate. You’ll notice the hip rafter doesn’t sit on the corner of the two wall pla…
Backing The Hip
- As with any hip rafter, an unequal hip rafter must have its top edge “backed,” or beveled, to match each of the converging roof planes. The question is how much to cut away. Determine the backing for each roof plane as shown in Figure 7. Place your square on the side of the hip rafter that will face the main roof, using the hip pitch for that roof, 8/155/8. Measure distance “A” along the unit …
Placement of Jack Rafters
- Before you nail up the hip rafter, be sure to lay out the position of the jack rafters. It’s a lot easier on the ground than 20 feet in the air. To determine the run of the jacks, draw in the first two jacks on the fullscale drawing of the hip rafter, as shown in Figure 8. We can then take all our measurements for the first jacks on each roof directly from the drawing, just as we did for the hi…
Valleys
- An unequally pitched valley rafter is laid out in the same way as the unequally pitched hip. The main difference between the two is that valley rafters sit on inside corners, while hip rafters sit on the outside corners. Each roof will be slightly different. Sometimes, instead of backing the hip, I’ll drop it in relation to the jacks. This still gives plenty of support to the sheathing. Also, I often dou…
