This method is considered the most accurate but you will need to get onto your roof to complete it.
How to measure your roof for shingles.
Here are the steps you can take to have the right measurements.
Next divide your total area by 100 to calculate the number of roofing squares you ll need to buy.
Roofing is measured in squares.
Measure the length of each individual plane.
Alternatively you can purchase a measuring wheel from your local hardware store.
Next use the pitch to look up the pitch multiplier for the roof online.
Below there is a simple triangle and the math used to work out.
Then each measurement is recorded on the diagram applicable to that roof surface.
To calculate the number of squares or bundles you need you should consider using the measurement method.
For each individual section of roof that you measured you will need to multiply the length by the width which will give you the square footage of that section.
If you use a measuring tape you ll need someone to hold the tape while you measure the area.
Measure and record your findings.
Your roofer will measure the surface of your roof to determine the total square footage which will dictate how many shingles must be purchased to fully cover the roof s planes.
The key is to be as accurate as possible since falling short or an overage could mean thousands of dollars when planning your roofing budget.
How to measure your roof for shingles.
How to measure a roof for shingles step by step the process of accurately measuring a roof involves first making a diagram of the roof to show the basic shapes of each roof plain and how they relate to one another.
The roofing materials are is measured in square feet which will give you the exact amount of materials you need for the roofing project.
To measure for roofing shingles start by calculating the area of each plane or section of the roof.
Climb onto your roof and measure each section by its height and width.
To calculate the size of the roof you need to measure the size of the roof as if it were flat account for roof pitch calculate square footage and finally determine how many squares of material are required for the roof the calculator above can handle all of this simply enter the length width and pitch and it will determine the size of the roof in squares.
To measure the length you need to spread the tape measure on.
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.
Record the measurements on your sketch of the roof.
The problem is that your roof might be too steep for you to walk on it without the correct equipment.
