Measure a roof from blueprints.
Building a brand new home obviously involves a brand new roof. The more traditional way of scaling out blueprints (roof plans) is to do it by hand using various tools such as a tri-ruler and other utilitarian items. But, some roofing contractors are leveraging high-tech to their advantage by using aerial and satellite technology to measure, and roofing applications to save time and money.
The architects who create the blueprints don’t always anticipate the specific needs of the contractors who will perform certain jobs on the property, such as constructing the roof. The architects’ drawings are often too complex for roof bidding purposes.
Having only a blueprint for a new home doesn’t mean that a roofing contractor must put aside their high-tech roof measurement and estimating application and pull out the ol’ tri-ruler.
How do you calculate roof area on plan?
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.
Why are roofs measured in squares?
In addition to being a larger unit of measurement, a square is used so that there’s a standardized measurement no matter the layout or shape of the roof. For example, 10′ x 10′ is equal to 100 square feet, or one square. 4′ x 25 ‘ is also equal to one square. Both of these would require one square of material to cover.
