How much does it cost to shingle a 1800 square foot house?
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.
How many bundles of shingles does it take to cover 1800 square feet?
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.
How much do most roofers charge per square?
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.
How many shingles do I need for a 12×16 shed?
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 that's 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.
- 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 - Note any skylights, chimneys or other parts of the roof that would not require materials. You can subtract those measurements from your total area.
- 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 - 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”. - 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”. - 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.
Example: 1000 sq ft / 100 = 10 squares
With those roofing measurement figures, you can then estimate the roofing supplies needed for a job.
We Are Specialists
Our Roof Measurement Technologies produce roof charts wherein we take utmost care of all the details like roof obstacles, accurate pitch estimation by seeing various faces on Aerial Photos (East, West, North, and South), lengths of the Eaves, hips, valleys, rakes, overhangs, the space of each aspect and total area of the roof. We assign line IDs carefully as this is crucial in designing roof outlines. For preparing the roof charts, we just need the address of the building and we can provide the roof layout with detailed accuracy. The measurements are taken from satellite and aerial images which are often as, or more accurate, than on-site measurements. We are experienced with Google Earth, BING, and Pictometry image sources. Our double-check quality process helps us deliver top-notch results to our clients.

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.
We Are Specialists
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.
