Correction: to find interior angle of hip caps, the angle needs to be perpendicular to the hip line. Thus, it is slightly different than just using 180°-(2)(hip walk angle). On a flat roof, this is perpendicular. But at other slopes, you need to adjust (for an 8:12 slope, you would need 5 1/8 slope [23.13°] rather than 5 11/16 slope [25.36°]). I did the math for you - these should be exact: Hip Cap Interior Angle (Bent at Supplier): 36:12 -> 95.74° 12:12 -> 120.02° 10:12 -> 126.17° 8:12 -> 133.69° 6:12 -> 143.00° 4:12 -> 154.62° 2:12 -> 166.14° 1:12 -> 172.39° Ridge Cap Interior Angle (Bent at Supplier): 36:12 -> 36.87° 12:12 -> 90.00° 10:12 -> 100.39° 8:12 -> 112.62° 6:12 -> 126.87° 4:12 -> 143.13° 2:12 -> 161.08° 1:12 -> 170.47° Also, FYI, here is hip walk angle for various roof slopes: 36:12 -> 25 7/16 : 12 (64.74°) 12:12 -> 8 1/2 : 12 (35.11°) 10:12 -> 7 1/16 : 12 (30.48°) 8:12 -> 5 11/16 : 12 (25.36°) 6:12 -> 4 1/4 : 12 (19.50°) 4:12 -> 2 13/16 : 12 (13.24°) 2:12 -> 1 7/16 : 12 (6.71°) 1:12 -> 0 11/16 : 12 (3.37°) And here is "triangle 3" (angle to leave on metal hip when cutting bottom): 36:12 -> 37 15/16 : 12 (72.45°) 12:12 -> 17 : 12 (54.78°) 10:12 -> 15 5/8 : 12 (52.48°) 8:12 -> 14 7/16 : 12 (50.27°) 6:12 -> 13 7/16 : 12 (48.23°) 4:12 -> 12 5/8 : 12 (46.45°) 2:12 -> 12 3/16 : 12 (45.44°) 1:12 -> 12 1/16 : 12 (45.15°)
Your video is great. I am having the same issue in finding my angle. I am build a 11'6" X 11' 6" gazebo that is similar to your build with a 6/12 pitch roof. Could you help out with the angle? Also, i am attempting to find how to cut the overlap where all four ridges meet. Can you provide some insight on how to do the overlap or how to make a cap? Thanks in advance.
For the ridges overlapping, I usually cut down the midline for the 8" or so that each ridge shoots past the top point, then cross the two flaps overlaying inwards as tight as possible and rivet. Can use mastic and caulk in addition.
6:12 pitch = 6:17 hip (walking up the hip) which is 4 1/4 : 12. The angle of the ridge cap bent at metal supplier would be 127°. The angle of the hip cap bent at metal supplier would be 141° (or just say 140°) (assuming four rather than eight hips on your gazebo).
Can you please put up the measurements in millimetres, as is way easier to follow. Maybe same video by put the text on the screen. You'll get a lot more hits as most the world uses metric. Cheers

Hip Cap Interior Angle (Bent at Supplier):

4:12 -> 154.62°

Also, FYI, here is hip walk angle for various roof slopes:

12:12 -> 8 1/2 : 12 (35.11°)

2:12 -> 1 7/16 : 12 (6.71°)
1:12 -> 0 11/16 : 12 (3.37°)
And here is "triangle 3" (angle to leave on metal hip when cutting bottom):
36:12 -> 37 15/16 : 12 (72.45°)
12:12 -> 17 : 12 (54.78°)
10:12 -> 15 5/8 : 12 (52.48°)

Great information and a great video!

Simply divide inches by 25.4 to get mm, or just 25 to make it even simpler.
Great observation on the hips! What would the angle be for a hip on a 2/12 pitch roof?
1 7/16 : 12
@@BradCaldwellAuburn Thank you Brad!
@ 11:20 How did you get the 5 and 11/16th and 12 for the Hip knowing it is an 8/12 roof?
Put 8 inch rise, "17 inch" run (for hips instead of normal 12 inch), and hit pitch on construction calculator. Can also do it via geometry.
I dont think nobody understood the first min
