Can a hip roof have different pitches?

For example, in an equal hip roof with an 8 / 12 pitch, the pitch of the hip rafter would be 8 / 17. But here it will be different, since the hip rafter doesn’t lie at 45 degrees to the commons. The pitch of the unequal hip rafter can be expressed in relation to either the main roof or the secondary roof.

Can a house have different roof pitches?

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.

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.

What pitch is a hip roof?

The most common hip roof pitch ratios fall between 4:12 and 6:12, although variations occur based on factors such as snow, rain, and wind conditions, which is because steeper hip roof pitch ratios allow for less accumulations of snow and rain on the roof, and lower ratios provide less wind resistance.

What are hip rafters?

Definition of hip rafter : the rafter extending from the wall plate to the ridge and forming the angle of a hip roof.

Can you mix gable and hip roof?

You can mix gables and hip roof styles. It works best with contrasts in siding, stone or other features. Keep in mind that when you change roof pitch it also affects length of overhangs and alignment of fascia. These features will also stand out and may throw off the intended look of your home.

What is the angle of a hip rafter?

King Commons and Ridge The last common rafters that support the ridge are called king commons (see illustration). The hip rafter intersects this 90° angle at a 45° angle and runs diagonally down to the building corner.

What is the pitch of an unequal hip rafter?

The pitch of the unequal hip rafter can be expressed in relation to either the main roof or the secondary roof. Since you need only one set of numbers to lay out the cuts, let’s work with the main roof, which has a unit rise of 8 inches.

How do you find the angle of a hip rafter?

Using the framing square’s 12th scale, find the hip angle as shown in Figure 3A. Draw a diagonal line between 9 feet (the run of the main roof) on the tongue of the square and 7 feet 6 inches (the secondary roof run) on the blade. This gives the angle of the hip rafter. Unit run of the hip.

How many rafters does a hip roof have?

Hip roofs are constructed with four rafters that usually meet on a ridge board that is situated at the middle portion of the roof. If we consider the rectangular shape of most buildings, then hip roofs will be constructed with two triangular sides and two trapezoidal sides; whereas in the case of square buildings,…

What are common rafters on a framing square?

Familiarity and basic skills with a framing square. Common rafters: Roof framing members that go from the top wall plates to the ridge. King common rafters: Common rafters in a hip roof that meet at right angles on either side of the hip rafter.
