Make sure to document the number of chimneys skylights or other obstructions and include dormers in your measurements.
How you messure squer roof.
1 roof square 100 square feet.
A home s roof is measured in squares.
Step 2 section the roof.
For instance if the roof is 1550 square feet then it is 16 squares.
If your roof is 5 000 square feet.
A square simply refers to a 10 x 10 square of roofing.
The pitch is the steepness of the roof.
Step 4 take ground measurements.
How to measure roof square.
Step 3 consider the roof slope.
The length l times the height h of a triangle is twice its area a2.
How to calculate your roof square footage first measure the length and width of each surface on the roof then multiply these values to get the square footage of that surface.
Use a pitch.
To find the pitch of your roof you ll first.
Stretch your tape measure along the walls from end to end.
L h 2 area calculating an area of a triangle when estimating a roof.
Find the length and width of the building s exterior walls.
To calculate the total square footage of the roof add up every plane s square footage.
Each square is 100 square feet.
Calculate the pitch of the roof.
To find the squares divide the overall roof area by 100 and then round up.
Multiply width x length this will give you the roof s square footage of one plane.
Start by measuring the width and length of your roof including dormers.
So if you divide your answer of a product of length times height by two you will get the area of a triangle.
If the house has an irregular shape measure each part separately figure the separate areas and add them together.
Convert the area to roofing squares.
