Comprehending how to figure roofing shingles needed is one of the most important tasks before starting any roofing project. Whether planning to replace the entire roof or fix a small portion, precise estimating is essential to ensure you get the correct supplies and avoid going over budget or running out.
Only Roofing Contractors walk you through how to figure roofing shingles needed for your private or commercial properties.
Square Footage Calculation
Once you have your measurements, multiply the length by the breadth of each roof piece to find its square footage. When dealing with triangles, multiply the height by the base and divide the result by two.
To calculate the overall square footage of your roof, sum the square footage of each part once you know it.
Recognizing Shingle Coverage
The standard unit of sale for roofing shingles is the ‘square,’ or 100 square feet of roof area. However, as it might differ across manufacturers and types, verifying the product specs or packaging for the precise coverage of the shingles you want to use is imperative.
Taking Overlaps and Waste into Account
It is critical to consider waste and overlaps when calculating the required quantity of shingles. Adding 10% to 15% to the overall square footage is usual advice to account for cutting errors, overlaps, and waste during installation. This extra space guarantees you’ll have enough shingles to do the job efficiently.
Finding the Total Number of Shingles
Divide the entire square footage of your roof by the space that one square of roofing shingles covers to get the total number of shingles that you’ll need. Before completing the computation, add the necessary percentage to your actual square footage to account for any waste or overlaps.
An Illustrated Calculation
Assume that the selected shingles cover 100 square feet each square on a 2,000 square foot roof. You would have 2,200 square feet of adjusted square footage after deducting 10% for waste and overlaps. To get the required number of squares, divide this by 100: 22,200 squares divided by 100.
Precautions to Make Precise Calculations
If your roof has a steep pitch, you should consider extra shingles to compensate for the increased surface area.
