Use our roof pitch calculator to find the pitch of your roof.
Staging sheets on a 4 12 pitch roof.
Roof pitch area multipliers.
We need to do something where that change happens so the panels can go down and water can come off hit the lower slope and come off the roof.
The square footage of a hip roof area is identical to the square footage of a gable roof of the same measurements.
One sheet 32 ft.
The pitch of the roof is the rise over a 12 inch run.
A 5 inch gap for instance is a 5 in 12 pitch.
Find the area of a roof.
Adjust from 4 12 to 12 12 pitch.
Once you know pitch you can find your roof pitch factor in the table below.
Anything more than 9 in 12 is considered steep.
This basically calculates the number of sheets needed for a gable roof.
The calculation is based on that the plywood or osb oriented strand board sheets are of a 4 x 8 size.
A low slope roof is anywhere from 2 in 12 to 4 in 12.
You ll have a steeper part of your roof turning into a lower slope so there s a steeper pitch up top and a lower pitch on the bottom.
If you have multiple sections of roof find the area of each and add them together to find the total area.
For example a 4 12 pitch roof that is 100 square feet.
Ultimate ridgehooks secure as much staging as needed even off both sides of the ridge without ever having to penetrate the roof sheathing.
Multiply the length of the roof in feet by the width of the roof in feet to find the area of the roof in square feet.
Angle the angle of a roof is the same as the roof s slope except instead of being.
We re going to do a pitch transition or change.
Next multiply the footprint of the roof by the multiplier below for your roof pitch to find the overall roof area.
There are two main categories of roofing.
100 1 054 105 4ft 2.
A flat roof has a slope of 2 in 12 or less.
For roof slopes greater than 6 12 up to 8 12 additional 90 degree slide.
Once the area is known divide by the area of a 4 8 sheet to find how much sheathing is needed.
Conventional slope roof range between 4 in 12 and 8 in 12.
Roof pitch calculator results explained.
Ideal for use on all pitched roofs even metal slate and shake roofs.
There are advantages and disadvantages to having a steep pitch versus a shallow or low pitch.
Pitch pitch factor 12 in 12 or higher 1 3 9 in 12 to 11 in 12 1 2 6 in 12 to 8 in 12 1 1.
Simply put pitch is expressed as rise over run just as the grade is simply this fraction expressed as a percentage.
A 4 12 pitch being 4 inches of vertical rise over one foot or 12 inches of horizontal run.
The run always remains constant at 12 inches.
