    People can even fall off a flat roof. They are all unsafe to a point. Any pitch just makes it more so.

    I built my 2 story log home in 1991 and me and a buddy roofed it, some 4L12, some 8L12 pitch. I've been on it sveral times since in maintenance, antenna, etc .... and this year I want to re-roof over with metal. I never used one before but this year, I'm 61 soon and I'll be using harnesses for me and buddy and maybe even a chicken ladder if it ain't in the way. Even back in 1991, when I was 37, that far end up near the peak with a 25 plus foot drop was a little high, you only get to fall like that once.

    joey is right 9/12 is pretty hard to stick to. I would not go steeper than 6/12 finishing as you go often the staples holding the paper will pull through and the breaks get put on when you hit the ground. With the proper equipment I have shingled barn roofs that run vertical for the first few feet.I would agree any roof regardless of pitch can be dangerous!

    Over the years I have found that age is a factor. My roof is 6/12 and 10 years ago I ran all over it. Now you could not pay me to go up there.

    Important point - if you contract for roof work (or any other work on your home) and the contractor is not licensed and insured you expose yourself to liability in the event a worker is injured while working on your house. If the company is licensed and insured they will use best practices with regard to working on the roof. The last thing a licensed and insured contractor wants is an accident that results in an increase in their already expensive Workers Compensation Insurance.

    I've worked on some pretty steep roofs. I'm not afraid of heights but it still was pretty scary trying to work on them. I think anything more than a 8 inch rise per 1 foot pitch would be too steep for anyone with a fear of heights to walk on.

    I can only speak for myself, but once a pitch is over an 8/12 i cannot walk on it without toeboards.

    I would think anything steeper than a 45 degree angle (12/12 pitch). would be unsafe to walk on.

    experienced roofers can easily walk a 6/12 and very carefully a 7/12.

    if you have proper shoes, (cougar-paws for instance), you can walk a 7/12 and VERY carefully walk 8/12

    i've seen roofers work 10/12 with only a 3' x 3' x 4" piece of foam to sit on and no other protection for falling

    6/12 was enough for me, but i'm just an electrician . some roofers are like cats up there.

    Any roof if it's as windy at your house as it is at mine.
