Roof pitch is typically expressed as a ratio, such as 4\/12, meaning the roof rises 4 inches for every 12 inches of run. When determining pitch of a roof, you are essentially comparing the rise to the run to find its slope.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"roof-pitch-ratio\">Roof Pitch Ratio<\/h3>\n\n\n\n<p>In simple terms, if a roof has a rise of 6 inches and a run of 12 inches, you have a pitch of 6\/12. You can also find the pitch and convert it to degrees using a roof pitch chart or roof pitch calculator.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"types-of-roof-pitch\">Types of Roof Pitch<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Low-slope roofs (1\/12 to 3\/12) &#8211; more common in contemporary homes and\/or commercial buildings.<\/li>\n\n\n\n<li>Medium-slope roofs (4\/12 to 7\/12) &#8211; Most of these would fall in the category of residential, which most do.<\/li>\n\n\n\n<li>High-slope roofs (8\/12 and above) &#8211; these would sometimes be unusual for <a href=\"https:\/\/www.aerialestimation.com\/pricing\" data-type=\"link\" data-id=\"https:\/\/www.aerialestimation.com\/pricing\" target=\"_blank\" rel=\"noreferrer noopener\"><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\">residential roofs<\/mark><\/a> at this pitch, but for areas that receive snow, a higher pitch is expected to allow snow to fall faster and add capacity for drainage.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"tools-youll-need-to-calculate-pitch-of-roof\">Tools You\u2019ll Need to Calculate Pitch of Roof<\/h3>\n\n\n\n<p>Before you determine pitch of roof, you will need these tools:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Tape measure \u2013 To measure the rise and run accurately.<\/li>\n\n\n\n<li>Level \u2013 A 12-inch level is the best option.<\/li>\n\n\n\n<li>Ladder or Roof Access \u2013 Always use safety equipment.<\/li>\n\n\n\n<li>Calculator or Phone \u2013 To do some quick math&#8217;s for conversions.<\/li>\n<\/ul>\n\n\n\n<p>You can also use a digital angle finder or roof pitch app which would be optional and allow you to measure roof pitch simpler.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"step-by-step-guide-to-calculate-pitch-of-roof\">Step-by-Step Guide to Calculate Pitch of Roof<\/h3>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/www.aerialestimation.com\/blog\/wp-content\/uploads\/2025\/10\/Gemini_Generated_Image_qo8jtwqo8jtwqo8j.png\" alt=\"calculate pitch of roof \" class=\"wp-image-774\" style=\"width:335px;height:auto\" srcset=\"https:\/\/www.aerialestimation.com\/blog\/wp-content\/uploads\/2025\/10\/Gemini_Generated_Image_qo8jtwqo8jtwqo8j.png 1024w, https:\/\/www.aerialestimation.com\/blog\/wp-content\/uploads\/2025\/10\/Gemini_Generated_Image_qo8jtwqo8jtwqo8j-300x300.png 300w, https:\/\/www.aerialestimation.com\/blog\/wp-content\/uploads\/2025\/10\/Gemini_Generated_Image_qo8jtwqo8jtwqo8j-150x150.png 150w, https:\/\/www.aerialestimation.com\/blog\/wp-content\/uploads\/2025\/10\/Gemini_Generated_Image_qo8jtwqo8jtwqo8j-768x768.png 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n<h5 class=\"wp-block-heading\" id=\"step-1-measure-the-rise\"><strong>Step 1: Measure the Rise<\/strong><\/h5>\n\n\n\n<p>Safely climb to the edge of the roof. Place the level horizontally on the roof and measure vertically from the level to the roof surface; that&#8217;s your rise.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\" id=\"step-2-measure-the-run\"><strong>Step 2: Measure the Run<\/strong><\/h5>\n\n\n\n<p>The run is usually 12 inches or 1 foot.

You can use this same method to calculate pitch of roof for any structure.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"using-a-roof-pitch-calculator\">Using a Roof Pitch Calculator<\/h3>\n\n\n\n<p>With online roof pitch calculators, it couldn&#8217;t be easier. Simply enter your rise and run, and the calculator will provide you with your ratio and angle, instantly.
