How do carpenters and architects express roof slope?
It is most often expressed as a ratio of inches of rise per 12 inches of run. A roof slope that rises 4 inches for every 12 inches of run is a "4 in 12" slope, or 4/12 slope, or 4:12 slope.
How do you measure the pitch on a roof?
Roof pitch is measured in "rise over run". In other words, how many inches does the roof rise vertically in 12" of horizontal run. If a roof rises 4" in 12" of run, you have a 4/12 roof pitch.
What is the slope in degrees of a roof with a rise of 12 and a run of 12?
45 degrees.
What does 3 and 12 mean?
It is usually referencing the pitch of a roof so a 3/12 roof would have a rise of 3" in a 12" span..... jimmyrjii
How do you determine pitch of roof?
The pitch of a roof is measure in a simple way. Rise over run. By this it means that, given the standard example of a 4/12 roof ,for every 12 inches or one foot of distance or run there is an according rise of 4 inches in height. If you wish to determine this you need to know the length of the rafters and then the height from the center of the rafter to the peak of the roof. For instance if the rafters happen to be 24 feet long that means that the run is 12 ft and if the height from the bottom of the rafter to the peak is 8 feet then you have a 8/12 pitch roof.
What percentage slope is a 5 12 roof pitch?
22.5%
What is a 5 12 pitch roof?
That is the Pitch or slope of the roof. It means that in one foot of horizontal measure you will have 5" of rise .
What is the minimum pitch requirement on a roof?
the pitch of a 7-12 roof slope meaning that for 12" of horizontal measurement (roof run) the vertical measurement (roof rise) is 7". Not totally sure but I believe the minimum to be about a 3-7 inch pitch 3 inch roof rise per 7 feet of horizontal measurement

What is a roof rise?
The slope. Example - a 12/12 pitch means for every foot of span there is one foot of rise.
What is the average slope of a roof?
5 in 12
A roof rises 4.5 feet over a horizontal distance of 14.42 feet What is the slope of the roof?
The pitch would be 3.74 4.5 x 12 = 54" rise 54 / 14.42 = 3.74
How do you find roof pitch?
Roof pitch is measured in "rise over run". In other words, how many inches does the roof rise vertically in 12" of horizontal run. If a roof rises 4" in 12" of run, you have a 4/12 roof pitch.

What is the difference between pitch and slope?
In regards to roofs. "Pitch" is a ratio of the total rise of a roof over the total span of a building. "Slope" is a ratio of the total rise of a roof over "half" the total span of a building. A building 40 feet wide with a total roof rise of 10 feet (from the top of the supporting walls) has a pitch of 10/40 reduced to 1:4 A building of the same dimensions will have a slope of 1:2 or 6/12 on the imperial framing square.
Calculate pitch of roof?
Roof pitch is rise and run. So if you have a 4/12 pitch, for every foot of run the roof rises 4 inches.
What is the lowest allowable slope for metal deck roof?
Follow the MFG recommendations, I would not install this on less then 4/12 pitch. Even though the screws have gaskets, if they are not torqued exact, they will leak,but with a pitch greater then 4/12 no water sits on roof giving less chance for leaking.
