Don t worry too much if you don t know how to measure a roof for shingles.
Measure my roof for shingles.
For example a 4 12 pitch roof that is 100 square feet.
Read the steps listed below to learn about how to measure your roof for shingles thus saving time and money by buying the proper amount.
The number you get will be an accurate estimate of how much area you have to cover for your roofing project.
Roof pitch area multipliers.
To figure out your roof s area a simple geometry can be used.
Although ceramic tile roofs are expensive they can have a life span of over 100 years.
Shingle roofs typically have a life span of 15 30 years while membrane roofs usually last 5 15 years.
If your roof measures 48 feet 15 m x 24 feet 7 3 m multiplying its length by its width would give you a square footage of 1 152 square feet 107 0 m 2.
Roofing is measured in squares.
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.
Use our roof pitch calculator to find the pitch of your roof.
Below there is a simple triangle and the math used to work out.
After this you will need to measure the length of the building from the ground.
This is the length from the peak of the roof to the edge where our ladder will be sitting.
Next multiply the footprint of the roof by the multiplier below for your roof pitch to find the overall roof area.
Required measurements include the following.
The pitch of the roof is the rise over a 12 inch run.
100 1 054 105 4ft 2.
When using this method you will need to measure the rake of the roof while standing on a ladder.
Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.
This doesn t have to be an exact sketch but the closer to scale that you draw the less room there will be for mistakes.
To measure for roofing shingles start by calculating the area of each plane or section of the roof.
Then multiply length x width to get the square footage of each plane.
It is often compared to slope but is not exactly the same.
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.
Of course this will be assuming that your home is rectangular.
Divide the roof into manageable sections.
Then each measurement is recorded on the diagram applicable to that roof surface.
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.

Next divide your total area by 100 to calculate the number of roofing squares you ll need to buy.
