How do you draw a roof design?
This is to indicate a wall thickness is if we’re looking in plan G. And we’re going to draw our roof lines over the top.
How do you calculate hip roof sheets?
To find the length of ridge capping required to cover one hip, measure the distance from the ridge line to the fascia on the roof plan (here 4000mm) and the gutter overhang and multiply by the Hip Length Roof Slope Factor for 30 degrees. Multiply by 4.
How do you build a hip roof?
You’ll have to make mirrored copies so that the 45 degree angles are going in the right. Direction to do that simply lay one jack down with a long point facing down and trace the whole jack out.
How do you calculate roof frames?
For example, if the slope is 4 in 12, and the run is 12 feet, the ridge beam height (M) will be 4 feet. The finished ridge beam height (Z) above the top of the wall will be (M) plus the Y Height. The formulas are: M = (R * X) / 12.

What is the angle of a hip roof?
Hip roofs have no large, flat, or slab-sided ends to catch wind and are inherently much more stable than gable roofs. However, for a hurricane region, the roof also has to be steep-sloped; at least 35 degrees from horizontal or steeper in slope is preferred.
How do you calculate hip roof tiles?
Take the roof width and multiply it by the slope height. This calculation will give you half the roof area, so then simply multiply by 2 to give you the area of both sides.

How is hip and valley roof calculated?
Hip and Valley Factor Formula
For a roof slope expressed as “X-in-12” (rise-in-run), the hip and valley factor is determined by finding the square root of ((rise/run)² + 2) for the slope of the adjacent roof sections. Divide the rise by the run (the run is 12). Square the result.
What is the pitch of a hip roof?
6/17
So, for this roof, the rafters have a pitch of 6/12, and the hips and valleys have a pitch of 6/17.
…
Is the pitch of a hip and valley the same as a main rafter?
| Rafter Pitch | Hip/Valley Pitch |
|---|---|
| 4.0 / 12 | 2.8 / 12 |
| 4.5 / 12 | 3.2 / 12 |
| 5.0 / 12 | 3.5 / 12 |
| 5.5 / 12 | 3.9 / 12 |
Do hip roofs need Rafter ties?
The connections between the hip rafters and the bearing at the corners are critical. The International Residential Code (IRC) does not address the requirements for such a roof and instead requires that hip (and valley) rafters be supported at the ridge by a “brace to a bearing partition” (paragraph R802. 3).

How many rafters are needed for a hip roof?
There are 6 of these rafters on every hip roof. King common rafters are structurally identical to the other common rafters.
Is a hip roof stronger?
Hip roof design is structurally stronger and more stable than gables because their construction requires less diagonal bracing – the hip framing filling the need.
How do you calculate rafter length on a hip roof?
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.

What size should a hip rafter be?
A normal common rafter is usually made out of a 2×6. A normal hip rafter, then, would be made out of a 2×8. Always make the hip from a board one size larger (in width) than the common rafters.
What is the slope of a hip roof?
Does a hip rafter have to be 45 degrees?
The 45 degress is most common because most buildings have a change in direction along the roof plate line of 90 degrees, hips and valleys are then required. You need rafters both sides of hip and valley rafters so the jacks that are cut into this are half the angle. 45 degrees.
How far can a hip roof span without support?
A roof truss can span up to 80′ without support, however in any home that distance would be impractical and incredibly costly. Trusses are designed to span spaces without interior supports, and spans of up to 40′ are the most common in today’s homes.
