Ideally, the first thing that homeowners should do before planning on their Anaheim roofing is to perform a research about the different terminologies on a roofing project. We know it can be difficult talking about a big investment while there are many unfamiliar terms. That is why we at Royal Roofing Construction provided a two-part blog about roofing terms. Part one of the blog series is about roofing squares.
Roofing Squares
This measures the roofing and exterior siding areas. A square is equivalent to 100 square feet or 10 square feet by 10 square feet. This measurement is more frequently used than actual measurement for areas because roofing professionals are discussing larger quantities of materials.
Also, a roofing square is also used together with a roof pitch, which is the degree of your roof’s inclination. It is usually expressed as the rise over the span, both measured in feet. The steeper the pitch of your roof, the harder installation is; the more roof squares to be covered, the more expensive it is.
Here’s a little example on how it can be used as a tool in estimating the cost of a roof replacement. For example, your roof’s pitch is at 4/12.
- You divide the slope by 12 to give you the ratio of the inches in rise per distance. For this hypothetical pitch, you will get 1/3.
- Square the value that comes up from the previous step. In this case, it’s 1/9.
- Add one to the value, which will give us 10/9. Calculate for its square root. That equates to a value of 1.0541.
- Multiply this value with the floor area. For example, it’s at 2,500 square feet, meaning a two-story house will have 1,250 square feet. 1,250 square feet multiplied by 1.0541 will be 1,317.625 square feet. This means you will be needing 1,317.625 square feet of roofing or around 14 (13.176 in exact) roofing squares of shingles.
Roofing squares can be used for both residential and commercial roofing in Anaheim CA. If you’re quite doubtful on your calculations, we at Royal Roofing Construction can always do it for you. Please don’t hesitate to call us for assistance.
