Am I right in reporting that the minimum slope for a shingled roof should be 3 inch rise in 12 in. run ?
I inspected one that was a two year old rebuild from tree damage to a flat roof and it looks like one or two inches max in 12 inch run.
they caulked the joints between shingles in the valleys also.
Also it is spongy in a large area, not just under foot when I walk on it. I weigh 240lbs but first one that felt this bad.
