A 10/12 means for every foot of run your rise is 10". so, 10' x 10" = 100" rise in 10 feet.
A 12/12 is 45 degrees. If you set a 45 degree piece of wood on the roof it should be level.
A roof that is 10 x 20 has an area of 200 square feet. The cost to have this size roof shingled is approximately 1,800.00.
We would have to know the wall height and how far from the exterior wall the point in your ceiling is. Example - you have a 8' wall and you want to know the ceiling height at the middle of the room 10' in from the exterior wall. So you would have 96" +(10 x 10) = 196" or 16 feet 4".
Some people can, but most can not. It would be best not to try walking it without roof brackets and planking.
The standard height of a residential roof typically ranges from 8 to 10 feet for the ceiling, while the overall roof height can vary significantly based on design and location. For commercial buildings, roof heights can be higher, often between 10 to 14 feet or more. However, local building codes and architectural styles can influence these measurements. Always check local regulations for specific requirements.
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.
Rise represents the change in y-values on a graph, e.g. if the rise is equal to 10, the y-value changes by 10. Run represents the change in x-values on a graph, e.g. if the run is equal to 5, the x-value changes by 5. knowing both the rise and the run is necessary to calculate the gradient, or slope of a graph - this is done by dividing the rise by the run, in this case it would be equal to 10/5 = 2
Slope = rise/run. Rise = 13-3 = 10. Run = 5-1=4. 10/4 = 2.5
A 12/12 is 45 degrees. If you set a 45 degree piece of wood on the roof it should be level.
By taking the square footage and the actual pitch of the roof and using a chart that will give you a 10 year frequency (average rain fall) per hr. Also a major factor is if the roof surface is for weather protection only or promenade
My roofer asked me what the slope of the roof was. It was an 8,12. That meant that the rise was 8 inches for 12 inches of run. A steeper roof would have more area and a flat roof would have less.At the corner I have to cut a 45 degree angle to make it match. That is a slope when turned flat of 1 over 1.The ramps in the USA have to be flatter than a slope of 1 over 10 and recommended to 1 over 12.
The ideal stair rise is around 7 to 8 inches, and the run should be about 10 to 11 inches for safety and comfort in a staircase design.
we add the 20 degrees to the 30digrees so it is 50
6 to 12,000 dollars depending on the work involved. Materials for a complete roof replacement run about 6,000 alone.
Slope is equal to rise over run. There are 12 inches in a foot, so 10 feet is actually 120 inches. Therefore, the slope is equal to 1/120.
Roofs may be functionally flat or "pitched". In building construction, roof pitch is a numerical measure of the steepness of a roof. A flat roof on the otherhand, is a roof which is almost level in contrast to the many types of sloped roofs. The slope of a roof is properly known as its pitch and flat roofs have up to approximately 10°. If you have a flat roof, there is probably a leak in it or there will be a need for a flat roof repairs in the future.
