Below there is a simple triangle and the math used to work out.
Measure my roof for shingles.
Although ceramic tile roofs are expensive they can have a life span of over 100 years.
When using this method you will need to measure the rake of the roof while standing on a ladder.
For example a 4 12 pitch roof that is 100 square feet.
To figure out your roof s area a simple geometry can be used.
Roofing is measured in squares.
Don t worry too much if you don t know how to measure a roof for shingles.
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 pitch of the roof is the rise over a 12 inch run.
Shingle roofs typically have a life span of 15 30 years while membrane roofs usually last 5 15 years.
Next multiply the footprint of the roof by the multiplier below for your roof pitch to find the overall roof area.
Then multiply length x width to get the square footage of each plane.
100 1 054 105 4ft 2.
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.
Roof pitch area multipliers.
To do this measure the length and width of each plane on the roof including dormers.
Next divide your total area by 100 to calculate the number of roofing squares you ll need to buy.
After this you will need to measure the length of the building from the ground.
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.
Then each measurement is recorded on the diagram applicable to that roof surface.
Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.
To measure for roofing shingles start by calculating the area of each plane or section of the roof.
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 estimate how many shingles you ll need first estimate the total square footage of your roof s surface.
Draw a rough layout of your roof.
How to measure a roof for shingles.
Required measurements include the following.
This is the length from the peak of the roof to the edge where our ladder will be sitting.
Divide the roof into manageable sections.
The number you get will be an accurate estimate of how much area you have to cover for your roofing project.
It is often compared to slope but is not exactly the same.
Use our roof pitch calculator to find the pitch of your roof.
