Getting set to install aluminium shingle on my new build. The house has a 8/12 gable roof with a complete wraparound porch that is 4/12. The eaves on the porch to the exterior wall is 7′, where would ice and water membrane be installed normally?
The wrap around porch has one valley and 3 hips, would the valley need any membrane?
The detached unheated garage I assume should not need any ice and water?
I have had numerous conflicting answers, so I figure I can solve it here with the expert roofers!!
Thanks for any input
