How Do I Calculate Roofing?

Roofing calculations are simple enough that anyone can do them, but there are many variables that can affect the final price tag. The type of material used, the size of the project, and the location all play a role in determining the final cost.

Determine the type of roof you need.

There are three main types of roofs: flat, pitched, and gabled. Flat roofs are typically found on commercial buildings, while pitched roofs are common on homes. Gabled roofs are usually found on barns and other farm structures.

The most important thing to know before calculating the cost of a new roof is what kind of roof you want. Roofing materials come at different prices depending on the type of roof you choose. For example, asphalt shingles are cheaper than slate tiles, which are much more expensive than clay tiles.

Find out what materials you’ll use.

You will need to calculate the total square footage of your roof. This includes the area covered by the roof itself as well as any additional space needed for vents, skylights, etc. Next, multiply the number of feet by the length of each foot (in inches) to determine the total square footage. Then divide the total square footage by the square footage of one square foot to find the number of squares per square foot. Finally, multiply the number of squares per sq. ft. by the price per square foot to arrive at the total cost of the roof.

Estimate the size of the project.

To estimate the size of the project, first figure out the total square footage of the roof. Multiply the number of feet by length of each foot (inches). Add up the numbers to determine the total square feet. Divide the total square footage by 1 square foot to find the average square footage of one square. Multiply the average square footage by the price per square to arrive at the total price of the roof.

Add up the total cost of the materials.

Next, add up the total cost of labor. This includes the cost of the contractor’s employees as well as any subcontractors who will work on the job. You’ll also need to factor in the cost of equipment such as ladders, tools, and scaffolding.

The final step is to multiply the total cost of materials and labor by the number of square feet of roof area. For example, if the total cost of materials is $10 per square foot and the total cost of labor is $20 per hour, then the total cost would be $100 ($10 x 100) plus $80 ($20 x 40). If the total cost of materials was $15 per square foot, then the total cost of materials would be $150 ($15 x 100) plus $60 ($15 x 40). In both cases, the total cost would be multiplied by the square footage of the roof area.

Subtract any discounts or rebates.

If you’ve received a discount or rebate, subtract it from the total cost. Be sure to check with your contractor to see if there are additional discounts available.

Roofers often offer discounts for multiple jobs, such as adding a second layer of shingles or installing a new gutter system. You should ask your contractor what discounts he offers before signing a contract.

Conclusion

Now that you know how to calculate roofing, you can get a more accurate estimate of the project cost.
