So, you thought geometry was something you could forget once you graduated high school, right? Most people probably can, but not if you are a roofing installation company! Roof geometry is an important part of the process as we need to know how to calculate roof pitch to best advise our customers about whether roofing shingles will be suitable and calculate the number of shingles needed to complete the roofing installation.
Roof pitch refers to the steepness of your roof. It is calculated using the rise and span of the roof. You’ll end up with a number that demonstrates how much rise occurs along the span. Examples include 1/12, 2/12, 3/12, 4/12, and so forth, with the higher first number increasing with more steepness. 7/12 pitch and above is considered steep pitch. 4/12 and below is considered low pitch. A high-pitch roof uses more materials and poses more danger during roofing installation, so you can expect it to cost more than a standard pitch roof. Anything below 2/12 cannot be covered by asphalt shingles.
The next thing about roof geometry is the roof design. A-frames and hip roofs are the most traditional and simple styles, as there aren’t any valleys involved that take extra work. More complex roof designs can cost more for roofing installation, as specialty materials may be needed, as well as more experienced roofing professionals to do the work.
The good news about roofing geometry is that you don’t have to dig out your old textbook to understand what is going on with your roofing installation.
