The faster that it rolls the greater the slope in many cases.
How to measure from floor to roof.
If this distance measures 4 inches you have a 4 in 12 pitch.
To measure flooring start by measuring the length and width of the room.
If there are any rectangular recesses in the room like a closet or bathroom repeat this process add everything together to determine the total.
If the room you re measuring the floors in isn t a rectangle or square divide it into smaller segments that are and calculate the area of each segment.
You ll need to figure out the vertical distance also known as the rise over a 12 horizontal segment also known as the run.
Then multiply these numbers together to find the area of the room in square feet.
On a ladder beside the roof place the level a foot or so up the roof hold it level and measure from the 12 inch mark on the level s bottom straight down to the roof.
Then multiply the 2 numbers together to get the area in square feet.
Measure an outside wall from end to end where the gable roof comes to a peak above the wall.
Another problem with this method is that it doesn t tell you how great the slope is i e.
Record these values as roof rise over run with the vertical measurement listed first and the horizontal second.
To measure the floors of a room measure the length and width of the room at the widest parts with a tape measure.
If it rolls away that indicates that the floor is not level.
Then calculate the pitch of the roof by placing a level against it angling the level so the bubble is centered and measuring the distance between the end of the level and the roof.
This is a rather complicated way to estimate a roof area and hardly suited to the diy fans.
The roof area is simply 114x18x2 plus 30x18x2 giving 5184 square feet which is perfectly adequate for estimating materials.
The next step is to measure the pitch also referred to as the roof slope of the roof deck.
This method does not work well on carpeted floors or ceramic tile floors.
To measure a roof start by measuring the length and width of the building s exterior walls and multiplying them to get the area.
Is there a 3 8 inch or 2 inch difference in 10 or 20 feet.
