Roof Measurement Report for RESIDENTIAL Roofs

For a 1800 square foot house, you will need approximately 23 squares or 69 bundles or 2000 pieces of 3-tab standard-sized shingles (12 inch by 36 inch) when overhangs is 1 feet and roof slope is 4/12.
 
A roofing square is equal to 100 feet on your roof. If your roof measures at 1800 square feet, you would need 18 squares of shingles to cover your roof.
With that said, on average, most roofing companies will charge somewhere between $3.50 and $5.50 per square foot, or $350 to $550 per square (100 square feet) to install or replace an asphalt shingle roof.
 
Multiply the product by the flat roof area and divide by 100:- our 12×16 shed square footage with overhangs is 252 sq ft, so 1.118 x 252 = 282 square feet, 282 / 100 = 2.82 squares. Round this number up and thats your answer, 3 squares!

How to Manually Measure a Roof

To manually measure a roof without the help of aerial measurement reports, you must visit a job site and climb onto the roof to take precise roofing measurements by hand. Here are the 6 steps to get a manual roofing measurement.

 
  1. Measure the width and length of each plane of the roof (including dormers), and then multiply those numbers to get the correct figure for the square footage of that area.
    Example: Plane 1 (A x B): 50’ x 20’ = 1000 sq ft
    Plane 2 (A x C): 50’ x 20’ = 1000 sq ft
  2. Note any skylights, chimneys or other parts of the roof that would not require materials. You can subtract those measurements from your total area.
  3. Add together the calculated square footage of each surface to get the figure for total square footage of the roof.
    Example: Plane 1 (1000 sq ft) + Plane 2 (1000 sq ft) = 2000 sq ft

  1. After determining the total square footage of the roof, you must calculate the pitch of the roof. Measure the vertical distance (rise) over a 12 inch horizontal segment (run).
    Example: The rise of this roof is 5”.
  2. Write down these numbers as the vertical measurement listed first and the horizontal measurement recorded second so you can find rise over run.
    Example: The rise over run of this roof is 5” over 12”.
  3. When you have the total square footage and rise over run of the roof, you can calculate the roof squares to determine how much materials are needed to cover the roof. To calculate the number of squares on a roof, you need to divide its total square feet by 100.
    Example: 1000 sq ft / 100 = 10 squares

With those roofing measurement figures, you can then estimate the roofing supplies needed for a job.

Our  Roof Measurement Technologies produces roof charts wherein we take most extreme consideration of the multitude of subtleties like deterrents on roofs, accurate pitch estimation by seeing various appearances on Aerial Photos (East, West, North, and South) additionally lengths of the Eaves, hips, valleys, rakes, overhang, the space of every aspect and absolute space of the roof. Additionally, significance is given while appointing line ID as this is pivotal in planning roof outlines. For setting up the roof graphs we just need the location of the structure and we can give you the roof outline of the structure with definite precision. The estimations are taken from satellite and ethereal pictures that are regularly as, or more precise, than estimations taken from the site. We are comfortable working with Google Earth, BING, and Pictometry picture sources. Our twofold check quality methodology helps us giving quality yield to our clients.

BENEFITS:

  • Faster Bids: The Skyroofmeasure Reports enable roofers to compile fast, competitive bids. Delivered in just one hour, the report lists the number of squares and predominant pitch for a residential roof. When contractors upgrade to an Skyroofmeasure Report, they can deduct the cost of the  Report from the total price.
  • Greater Profitability: With an Skyroofmeasure Report, roofers receive the highly accurate roof measurements and diagrams they need to complete the job. Those precise details result in more efficient material orders and production plans, leading to less waste and increased profits.
  • Superior Accuracy: Before using Skyroofmeasure Reports, one group of contractors required material redeliveries 46% of the time and pickups 37% of the time. After switching to Skyroofmeasure Reports, only two of their jobs needed redeliveries, and the number of pickups fell to zero.
  • Professional Estimates: The Skyroofmeasure reports are delivered as a professional document with a customizable cover page included at no additional cost to the contractor. The property owner report offers a professional presentation utilizing  aerial imagery and the Skyroofmeasure 3D model. The ability to leave impressive aerial views with customers along with rapid estimates brands the company as forward thinking and reliable.
  • Negotiate and track labor charges: No haggling over steep charges or other crew payment issues when using Skyroofmeasure reports. Accurate pitch, area and line measurements make tracking labor easy and collaborative. Instead of square measurement disagreements, all parties can use the measurements for rapid and profitable labor and production.
  • Increase the number of sales calls made in a day: Contractors receive the measurements and information needed to prepare proposals ahead of time. Spend time selling, not measuring and estimating. The time saved means more calls can be made in a day resulting in more closed sales.
To determine if a roof is square, measure from the eaves to the ridge at several points along the roof to see how parallel they run. Do the same from one gable end to the other to determine parallel and also measure the roof diagonally.
 
How many roofing squares is 1600 square feet? So a roof that has 1600 square feet of area has 16 squares. Remember that unless the roof is flat, the square footage of the building is different than the square footage of the roof.

Asphalt three-tab shingles cost around $1 to $2 per square foot.
