    Hi Michael, I found your lecture very interesting and informative. I think its good to explain fully how it all works. I, personally, will remember this lecture and put it to good use in the future. I just have one question at 18:13 onwards where the small triangle at the top shows a ratio of 1:1.5 re the slope. Is this a mistake or maybe I'm not fully understanding this. Can you please clarify??

    Appreciate Video! Excuse me for butting in, I would appreciate your thoughts. Have you heard about – Mahorrla Wooden Paradise Method (search on google)? It is an awesome one off product for building better sheds and woodworking without the headache. Ive heard some decent things about it and my m8 after many years got cool results with it.?

    I do engineering for a living and this is making a simple problem being made complicated. Why do you want to complicate such a simple job?

  • calvin busch 1 year ago

    I used to cut roof rafters for framing conventional roofs with a calculator also and then built them. I understand how to do this, but after listening to you explain this I see why I hated math in school. Sorry, but while this is an excellent explanation, it is dry enough to put me back to sleep.?

    Nate – We are developing a specialized app for commercial single ply roofing application (Rubber / PVC / TPO), which could also be used for modified bitumen with small modification.

    We will release it as stand alone product and combined with this steep slope calculator.
