Manual Calculations for Asphalt Shingles
It’s essential to understand manual calculations for asphalt shingles so that you know what goes into the estimates provided by the tool. Let’s look at how to measure a roof for a shingles calculator and how to perform manual evaluations.
Roof Area
To find the total roof area, measure each plane of your roof. Most roofs in Chicago have different shapes like rectangles, triangles, and trapezoids:
- Rectangles: Multiply length by width.
- Triangles: Use the formula: (base*height)/2.
- Trapezoids: Use the formula: ((top edge+bottom edge)*height)/2.
Add all these areas together. Subtract areas not covered by shingles, such as chimneys or skylights. If you don’t have time to do the manual measurements and calculations, roofing services near me can do it for you.
The Number of Shingle Bundles
Shingles come in bundles; each bundle covers about one-third of a roofing square (100 square feet). To figure out how many bundles you need:
- Calculate roofing squares. A roofing square represents 100 square feet. Divide the total roof area by 100 to get the number of squares.
- Convert to bundles. Multiply the number of squares by three to estimate the amount of materials.
It’s wise to round up and add an extra bundle for waste. Also, having extra shingles guarantees color consistency over time in case you need to make spot repairs.
Adjustments for Roof Pitch and Complexity
Instructions for Using the Asphalt Shingle Roof Calculator
Getting the right number of asphalt shingles in Chicago doesn’t have to be a headache. Follow these steps to simplify your roofing project:
- Note your roof’s dimensions, pitch, and any features like dormers or skylights.
- Open an online shingles bundle calculator.
- Enter the numbers for each section of your roof. If the roof has multiple sections, calculate the area for each one separately and add them up.
- Enter the pitch ratio (e.g., 6/12) since it impacts your required shingles.
- Add details about chimneys, vents, or skylights to adjust material estimates.
- Press the calculate button to get an estimate of shingle bundles and other materials like underlayment and nails.
- Look over the results and tweak any inputs if needed for accuracy.
Input Data Needed for Accurate Roofing Calculations
You need some key info about your roof to use an asphalt shingle roof calculator. Here’s what you should gather and why it matters for planning calculations in Chicago:
- Roof dimensions. Measure the length and width of each section of your roof. This helps calculate the total area of the roof.
- Roof pitch. Find out how steep your roof is (its pitch). A steeper roof means more surface area to cover. This factor is considered by almost every asphalt shingle roofing cost calculator.
- Shingle type and size. Decide which size and type of shingle you’ll use. Different types, like commercial asphalt shingles and residential materials, cover different amounts of space per bundle.
- Additional roof features. Take note of ridges, valleys, eaves, or rakes on your roof. These spots usually need extra materials like ridge caps or valley flashing. With this data, workers in Chicago could do their job more quickly.
Understanding the Results Provided by the Calculator
When you get results from an asphalt shingle roof cost calculator, it’s key to know what each number means. Let’s break down how this data impacts your roofing job.

Budget Planning: Estimate Roofing Costs with Precision in IL
If you are unsure about what material to use and decide between asphalt shingles vs. tile roofs, you’ll see that shingles are generally less expensive. Once you have the numbers from the calculator, you can quickly estimate the costs of your roofing project, which will be important for your final decision. It is notable to mention that your estimate may differ from the estimate of the roofing company near me in the suburbs or the Chicago area. This is due to transportation or additional services. Below is an example of how to estimate the budget.
Steps to Budget Your Roofing Project in Illinois
First, calculate material costs. For instance, if your roof needs 2,368 squares of shingles determined by the calculator, and the material costs $4 to $6 per square foot, you’ll spend between $9,472 and $14,208 just on shingles.
Next comes the labor cost, which varies depending on the complexity of your roof design. For a simple gable roof with minimal angles, labor may be less expensive. However, more complex designs can expand these costs significantly. It is wise to consult with roof contractors close to me who can provide detailed quotes.
Consider additional expenses such as underlayment needs and nails. A roof covering 2,368 square feet might require six rolls of underlayment if each roll covers 400 square feet of roof. Also, typically, around 23,040 nails are needed (four per shingle), especially in high-wind Chicago suburbs and Chicago areas where more secure fastening is necessary.
Accounting for Waste Materials
Don’t forget the waste factor adding about 15% to the material requirements measured by the asphalt shingles calculator. This buffer guarantees you won’t run out of the material mid-project due to cutting errors or other unexpected setbacks. If the initial calculation indicates you need 72 bundles, you should plan for around 83 bundles to account for waste.
Tips for Avoiding Errors When Using the Calculator
It’s common to make mistakes when firstly using a calculator to estimate shingles in Chicago, but you can avoid them with a bit of care. The following tips will help you get accurate results:
- Take precise measurements. Measure each section of your roof, including additional structures like gables and dormers. Use tools such as a reliable tape measure or laser level for accuracy.
- Account for overhangs and valleys. They add the surface area of your roof that needs shingles, so include these features to get an accurate measurement.
- Use the correct units. Always double-check that the asphalt roofing shingles calculator uses the right units like square footage. Mixing up units (e.g., square feet with square meters) can throw off your entire calculation.
- Understand shingle sizes and quantities. Know how much area standard shingles cover to calculate the amount of materials needed.
- Verify the inputs. Double-check all inputs in the calculator before finalizing your order, from your measurements and pitch adjustments to any other factors affecting the calculation.
