Can a roof have 2 different pitches?
According to MyRooff, a dual-pitch roof is a gable roof with two sloping sides that meet together at the top, forming a central ridge. Each side extends far enough to cover an entire structure. The ridge is the highest point on a roof, and you'll hear professionals occasionally refer to it as a peak.
Can I mix and match roof pitch?
3. Unless you're absolutely sure of the effect you're after, avoid combining different roof pitches. More often than not, varied pitches look disorganized or, worse, like a construction error. Stick to a uniform pitch, and rely on the size and arrangement of roof masses for effect.
How do you join two roof pitches?

Gently bend the flashing using the edge of the lumber until both sides of the flashing match the slope of the two roof pitches.
What is a dual pitched roof?
A pitched roof is a roof of a building that has a slope or angle to it. Generally pitched roofs are dual pitched, meaning that they have two sides, but pitched roofs can also be mono-pitched, sloping in one direction only.
Does a hip rafter have to be 45 degrees?
Hip rafters are fastened at a 45-degree angle to the ridge board down to the building's four exterior corners. It is also used to nail the jack rafters' tops. Jack rafters are attached to the hips and slope down to the outside walls.
Can you mix roof styles?

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?

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?

Closing
Those are all the information we know about joining two roofs with different pitches. Maybe all the steps that we mentioned above seem easy to do.
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 size should a hip rafter be?
The rule of thumb is that hips, purlins and ridge boards are at least 1.5 times the depth of the rafter.
How do you find the pitch of a hip roof?
The angle, or pitch, of a roof is calculated by the number of inches it rises vertically for every 12 inches it extends horizontally. For example, a roof that rises 6 inches for every 12 inches of horizontal run has a 6-in-12 pitch.
What is the angle of a hip rafter?
The hip rafter intersects this 90° angle at a 45° angle and runs diagonally down to the building corner. The king commons at the ends of the ridge are the same length as those at the sides.
What is a standard pitch of a roof?
The most commonly used roof pitches fall in a range between 4/12 and 9/12. Pitches lower than 4/12 have a slight angle, and they are defined as low-slope roofs. Pitches of less than 2/12 are considered flat roofs, even though they may be very slightly angled.
Does a hip roof support itself?
A hip roof is self-bracing, requiring less diagonal bracing than a gable roof. Hip roofs are thus much more resistant to wind damage than gable roofs. Hip roofs have no large, flat, or slab-sided ends to catch wind and are inherently much more stable than gable roofs.
How do you calculate hip rafter size?
Divide the span of the roof by two to obtain the run of the roof. The span of the roof is 25 feet, so the run of the roof is 25 / 2 = 12.5 feet. Divide the run of the roof by the cosine of the angle of the roof to obtain the length of a common rafter.
Which roof pitch is best?
Pros. Since a low pitch roof doesn’t require as many shingles, more often than not, a low pitch roof will end up being more cost-efficient during installation. The lower pitch of the roof means greater walkability. Low pitch roofs are safer and easier to access when maintenance and/or repairs are needed.
What is a half hip roof?
2. Half Hip or Jerkinhead. Also referred to as jerkinhead or clipped gables, the half-hipped roofs have two short sides that form eaves. They are usually characterized by their upper points of gable rather than a small hip. One advantage of a half hip roof is the ease of drainage from the gutters. 3. Dutch Gable Hip.
Why are hip roofs so popular?
This is thanks to the four sides of the roof that shelter the house from excessive heat. These eaves keep the house adequately protected from extreme weather, thus making hip roofs one of the most energy-efficient design options.
What is a Dutch gable roof?
A dormer can also be installed in the center of the hip roof for additional living space. This provides a beautiful decorative touch to the hip roof as well as transforming the attic into a functional living space.
How long does a hip roof last?
Hip roofs can last up to 5 decades if not more, provided they are constructed properly. The lifespan of a hip roof depends on the quality of the materials and the maintenance they receive. To make your hip roof last longer, use metal roofing or clay shingles and carry out regular maintenance to prevent water leaks.

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…
