Residential Roofing Estimating Process

Gone are the days for companies that still rely on climbing ladders and taking measurement manual by measuring tapes for residential estimation. This era is for techniques like that of eagle view and aerial-measurements that let you accurately measure a roof, saving time and money, even before materials are ordered.

The Contractors just tell SkyRoofMeasure the property’s address online through their website. The technicians pull high-resolution images for measurements and detailed reports that show details like length, pitch, area, and even more. With the mobile app, you can work with their interactive photo editor tool to mark areas of roof damage and other necessary details. You can combine multiple reports online with the aerial measurement reports.

Besides the aerial view, drone camera technology has even taken the roof measurement and estimation to the next level. You never have to ascend that ladder again, instead, a roof measuring drone camera and estimating software that you can carry in a hand-held tablet eliminates the need to climb onto the roof.

With more precise estimation and lower liability costs, you can seal more deals and generate more leads with improved safety and efficiency.

CALCULATING THE AREA (TRUE)

If you want to get the exact area measurement for your roof, you can follow these steps:

  1. Once you have your roof’s pitch, divide the number by 12. (For example, if your roof’s pitch is 4 in 12, you would divide 4 by 12. This would yield 1/3.)
  2. Next, square your result. (If your number is 1/3, squared would yield 1/9.)
  3. After that, add 1 to your number. (1/9 + 1 = 10/9.)
  4. Next, figure out the square root of your new number. (The square root of 10/9 is 1.05.)
  5. Next, use your measuring tape to measure the length of your house. (Be sure to include overhangs.)
  6. After that, measure the width of your house. (Be sure to include overhangs.)
  7. Multiply your house length by your house width to get the area. (For example, 40 feet x 30 feet = 1,200 square feet.)
  8. Next, multiply the area by your roof’s pitch. (1,200 x 1.05 = 1,260 square feet.)
  9. To allow for hips, ridges, and waste, add 10% of your final number for a gable roof and 17% of your final number for a cottage roof. (Your total number would be either 1,386 or 1,474 square feet.)

How To Calculate The Cost Of A Roof Replacement

Getting Rid of the Previous Roof

Expect to pay at least $1,000-$2,000 for the contractor to remove and haul away the previous roof from your home. Obviously, this cost will increase with the size of your roof and the difficulty of workers to remove the old shingles—the longer it takes, the more man-hours will be required.

Shingles

First, some basic roofing terminology: A 10-by-10-foot section of roof is commonly referred to as a square. That equals a 100 square feet, so a 2,500-square foot roof is 25 squares. Here are some basic estimations on the cost of one square of shingles (actual costs will vary, of course, depending on shingle quality, materials used, and brand):

  • Asphalt shingles: $80-$120
  • Cedar shake shingles: $600-$900
  • Slate tile: $300-$500
  • Metal roofs: $200-$1500

Other Roofing Materials

From the nails used to the underlayments that shingles will reside upon to the flashing that secures joints, seams, and edges, the materials to hold your roof together will be part of your investment. The quality of these materials can vary—generally, the more you spend, the better the roof—but plan on about $50-$100 per square.

How are Roofing Estimates Determined?

When experienced roofing contractors arrive to provide a free estimate, they consider several factors. This is how they go about giving you an accurate cost analysis.

  • Roof Measurement

Roof measurements are taken digitally. Roofing contractors use technology like satellite imagery or drones. Their calculations include such factors as the slope, roofline peaks, and the overall complexity of your roof.

  • Roof Inspection

In a thorough roof inspection, roofing contractors assess the condition of your roof. This helps them determine the scope of the project.

  • Roofing Materials

Experienced roofing contractors will explain the advantages of various materials and make recommendations concerning the best roofing system materials for your home or business. They will factor in such things as shingles, ventilation, roof accessories, and warranty.

  • Calculating Costs

Once the roofing contractor has obtained this information, the company is prepared to provide an accurate estimate to the question: How Much Does the Average Roof Replacement Cost?

The roof replacement specialists will factor in: labor, materials, warranty, and permits, the cost of removing old materials, and cleaning up.

For a basic project in zip code 47474 with 125 square feet, the cost to Install a Asphalt Shingle Roof starts at $3.75 – $4.92 per square foot*. Actual costs will depend on job size, conditions, and options.

To estimate costs for your project:

1. Set Project Zip Code Enter the Zip Code for the location where labor is hired and materials purchased.

2. Specify Project Size and Options Enter the number of “square feet” required for the project.

Roofing Calculator – How to Measure a Roof

How to Calculate Total Square Footage of Your Roof. To find your roof’s total square footage: Measure the length and width of each plane on the roof (including dormers) then multiply length times width. Add the square footage of each of the planes together.

What is a roofing square?

A lot of different factors determine the cost of your new roof. One of the biggest factors is the size of your roof that’s calculated by a measurement called a “roofing square”.

A roofing square is a 10×10 area that’s equal to 100 square feet of roof surface. The amount of roof squares determines how much roofing materials and labor it takes to replace your roof. 

The more squares your roof has, the more your roof replacement costs. Usually, it takes about 3 bundles of roofing materials (asphalt shingles) to fill a roofing square. 

But it ultimately depends on what type of roofing material you choose for your roof replacement. Some homeowners get confused by the term “roof square” and like to see the cost broken down by square footage. 

If this sounds like you, all you have to do is take the cost per square and divide it by 100. For example, if the cost of your roof is $600 per square, that comes out to $6.00 per square foot. 

If there’s any confusion about the terms you see on your roof estimate, don’t hesitate to ask the roofing contractor to explain them until you fully understand. 

Estimating Roof Area Using Pitch and Square Footage

If you are mathematically inclined or have a roofing calculator, you can estimate the roof area if you know the pitch of your roof and the square footage of your home. To illustrate, if your pitch is 4/12 and your two-story home has 1,400 square feet on each floor, these are the calculations.

• Divide the pitch. For a 4/12 pitch, the answer is 1/3.
• Square the above answer, which in this example would yield 1/9.
• Add 1, expressed as a fraction. That is, you would add 9/9 + 1/9 for a total of 10/9.
• Take the square root of 10/9, which is approximately 1.054.
• Multiply 1.054 by 1,400, the square footage of the home used in this example. You should get 1,475.6.
• Divide 1,475.6 by 100 to determine the number of squares required. You will need at least 14.756 squares of roofing. However, you should add about 10 percent for starter strips, valleys, waste and hip and ridge.

Estimating Materials Based on Actual Measurements

Measuring each roof plane requires you to actually go onto your roof. If your roof has a number of planes and numerous hips, ridges and valleys, this is the most accurate way to calculate the materials needed. Take a metal tape measure and a pen and paper. Measure each plane’s length and width. Record your measurements. Once you are safely on the ground, use your measurements to determine the square footage.

• For rectangular areas, multiply the length by the width. For example, if a plane measures 30 feet by 100 feet, this would be 3,000 square feet.
• For triangular areas, you may need to dust off your geometry book. If the area forms a right triangle, you can make use of the Pythagorean theorem. Otherwise, you might want to look up how to calculate the semiperimeter and then use Heron’s formula to find the area.
• Be sure to add extra for valleys, hips and ridges.
