Roof Pitch Calculator
Looking to design a perfect roof pitch? Look no further than ArcSite’s roof pitch calculator. Contractors often use a roof pitch calculator in construction projects, be it building new homes or refurbishing older ones. All houses and buildings have a roof, and almost all roofs have a specific slope or inclination. Even flat roofs, though small, have a certain slope, also referred to as pitch. A roof pitch is useful in stopping snow and rainfall from accumulating on the roof.






What is the importance of roof pitch?
Roof pitch helps determine how much roofing material you’ll need to build the roof of your house. In terms of HVAC, roof pitch directly affects the ceiling cavity, which is essential for an efficient airflow. You must choose the roof pitch according to the weather conditions in your area. Naturally, a steeper roof is vital in areas that receive heavy rainfall and snow. An appropriate roof pitch also improves the aesthetic appeal of your house.



In theory, roof pitch is calculated as the vertical rise over the horizontal run of the roof. Roof pitch is expressed either in terms of (Pitch:12). For instance, if the pitch is 3:12, for every 12 inches, your building extends horizontally and rises by 3 inches. To calculate the pitch, you must measure rise and run manually. “Run” is the horizontal distance of how much the roof extends outwards, whereas “rise” is the distance from the top of the wall to the peak of the house.

FAQs
Once you know the rise and run, you can simply use the equation of a right-angled triangle to evaluate rafter length: (Rafter length)^2 = Rise^2 + Run^2. This will help you determine the cost of rafters for your roof.
Roof pitch determines the angle at which solar panels are installed on your roof. For most houses, a roof pitch of 35 degrees is ideal for sonal panels.
With ArcSite’s roof pitch calculator, you can determine the number of rafters for your roof. You can then evaluate the roof cost based on the length and cost of each rafter.
