Of ridge or hips with each bundle of three tab shingles that come three bundles to the square.
How do you estimate roof shingles.
Find the square footage of the roof.
If the existing shingles are standard 3 tab shingles you can get this measurement by taking note of the number of tabs along the eaves and ridges then determine the length in feet.
Like regular shingles they overlap for a 5 in.
Our calculator will help you estimate the amount of roofing shingles needed for your project plus the cost of materials and accessories.
As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles.
How to use roof calculator.
Measure your roof accurately.
To do this you need to note that one tab will be equal to 1 foot.
This roof shingle calculator requires four basic inputs.
Use a measuring tape preferably 50 or 100 feet long and get exact ground dimensions of your house.
Simply enter your roof dimensions and roof type such as gable or hip and approximate roof pitch.
There are also 29 standard sized shingles measuring 12 inches by 36 inches in each one of these.
Determine the total number of squares.
While it is possible to estimate the amount of necessary materials using only the total roof area measurement as can be seen from the table depending how large the pitch of the roof the actual area of the roof can differ by up to 2 236 from the measured total area at a pitch of 24 12.
You can cap about 35 lin.
Roofing material calculator estimate bundles of shingles and squares calculate the size of your roof and estimate how many bundles of asphalt shingles rolls of felt and squares of roofing material are needed for a new roof.
Add the price per square of materials to get an estimated material cost.
Dimensions measured from the ground.
Exposure on roofs shingled with three tab or no cutout shingles you simply cut standard shingles into caps.
Enter appropriate roof pitch slope.
You can get a decent estimation this way.
Roof length measured in feet roof width measured in feet.
Enter your zip code.
You will then have to get the measurement of the rake of the roof.
One way to get an estimate is to take the square footage or meterage of the building and multiply it by the slope factor pitch of your roof.
Determine the bundles of shingles.
With that as background you are now ready to estimate how many shingles you will purchase for your roof project.
