I got a bunch of shingles for free to use on my new shed but I’m not sure how much reveal is appropriate and what second and subsequent row trim dimensions to use. They are not standard three tab nor any architectural style that I’ve seen.
They were stored in a barn and have some cracks but have no nail holes so appear old but unused. The overall size is 14 X 40" plus a notch that I suppose is for helping to align them when installing.
Each shingle has three tiered layers: 14" wide; 6-3/4 wide; and 5-3/4. There are two similar but different patterns, both with huge cutouts through all three layers.
Any advice would be appreciated. I am not a pro, just a DIY who bought a fixer house.
