This video is all in good fun. I spend a lot of time doing research before posting information online. It’s too bad that the comment section gets out of hand sometimes and false information is presented. Roof slope = rise over run - meaning a 4/12 slope has 4” of rise over 12” horizontally. Mr. Trevor, you requested a special video since you thought the information I presented in my video a couple of days ago was wrong, so here it is. Hopefully it shows an easy way to find the slope of any roof using a speed square with a level. The square will tell you the roof pitch or degrees so that you can easily get a rake angle, say for siding as an example. Thank you Trevor for the idea of a simple way to explain roof slopes and how to determine the angle of a roof. Cheers and thanks for watching. . . . . . . . . . . .
