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