How do I calculate the size of my roof?

Multiply your house length by your house width to get the area. (For example, 40 feet x 30 feet = 1,200 square feet.) Next, multiply the area by your roof’s pitch. (1,200 x 1.05 = 1,260 square feet.) Follow Us for more details Please!

What is the most common roof pitch?

Conventional slope roofs are most common with residential roofs. This means the slope has a pitch between 4/12 and 9/12 on most homes. Roofs with a pitch exceeding 9/12 are called steep slope roofs.

How do you calculate rafter length?

 
 
If you are calculating rafter length from the center of the ridge beam (as shown below), you will need to subtract half of the thickness of the ridge beam from the top end of the rafter. For example, if the ridge beam is 1.5 inches thick, subtract 3/4 of an inch from the overall rafter length.
 
Rafter Dimensions

As roof pitch is lowered, the weight burden on the rafters increases. For low-pitch roofs, building codes may require larger dimension rafters.
 

How far can a 2×6 rafter span without support?

How Far Can a 2×6 Rafter Span? A 2×6 rafter can span 14 feet 8 inches when spaced 16 inches apart with No. 1-grade southern pine lumber on a roof with a 3/12 slope or less with a maximum live load of 20 pounds per square foot and a dead load of 15 psf.

Learn How To Measure a Roof From Blueprints

To find your roof’s total square footage:
  1. Measure the length and width of each plane on the roof (including dormers) then multiply length times width.
  2. Add the square footage of each of the planes together.

How do you measure for a new roof?

To do this, measure the length and width of each plane on the roof, including dormers. Then, multiply length x width to get the square footage of each plane. Finally, calculate your roof’s total square footage by simply adding the square footage of each of the planes together.
 

How do you measure roofing materials?

Measure the length and width of each portion of the roof, multiply length by width for each plane, and then add the planes together for the total square footage. If you have a simple gable roof, you’ll only need to measure and sum up the 2 planes of the roof. Follow Us.

CALCULATING THE AREA (ESTIMATED)

If you don’t want to do a lot of measuring, you can use your pitch calculation to get an estimated square footage of your roof:

  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. Determine the square footage of one floor of your home. (For example, if you have a two-story home that’s 2,600 square feet, one floor would be 1,300 square feet.)
  6. Multiply this number by your most recent result to get the estimated square footage of your roof. (1,300 x 1.05 = 1,365 square feet.)

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.)

Method 2

Determine the roof area by using a mathematical formula that accounts for the roof length, total span, and roof pitch:

  1. Determine your roof pitch by using a pitch gauge (available at most home improvement stores) or a smartphone app (available free through any app store).
  2. Measure the length of the roof surface, including overhangs.
  3. Measure the span of the roof, including overhangs.
  4. Multiply the length x the span. The result will be the plane area. Use the chart below to calculate the total area of the roof.
  5. Calculate the total roof area – Plane Area x Correction Factor = Roof Area

Roof Report by Blueprints

Once the drawing was exposed to light, the exposed parts turned blue, while the drawing lines blocked the coated paper from exposure and remained white. … For decades, bluelines were the way to make copies of architectural drawings. To this day, they are often called blueprints.

The most important thing is to match the scale of the ruler used for measurement to the drawing.

  1. Unroll the blueprint onto a flat surface. …
  2. Find the scale of the drawing. …
  3. Choose a scaled ruler that accurately matches the scale of the drawing. …
  4. Lay the proper scale next to the item on the drawing and take the measurement.

4 Tips for Reading Blueprints

  1. Begin with the title block. The title block is the first piece of information you’ll see in construction site plans. …
  2. Study the plan legend. …
  3. Find the blueprint’s scale and orientation. …
  4. Look for notes from the architect.
