Eight boxes in total were used to seal the roof. The first layer took four boxes and the final layer the remaining four.
Grace Ice & Water Shield won out over all the other vapor barriers because if its supreme protection against water. The box advertises "75 ft" with a total of 225 sf coverage. I rolled out thirty seven and a half feet, cut it, and then rolled out the next half and came up six feet short. So I unrolled every one of the eight rolls purchased, and came up short on every roll. Every roll was 68 ft. I contacted the company and they bought me off with a $100 gift card because they would not send me another roll.
The wrinkles were ubiquitous. They come out with a solid boot press. The patchwork was inevitable due to the shortage.
I ended up having to borrow some roofing felt from a friend to finish the final section of the roof. Here, the patchwork pieces getting laid out before installation. This process took a day. The rain came that evening and revealed a small leak on the east side. I sealed that the next day with liquid rubber clear roofing sealant. The rain came again that night, and voila! Bone dry.
