My house roof is shingles... I have rolled ashfalt on my porch that attaches to house... It is transtion up the house about 3 feet, over the ice and water shield... I want to removed rolled roof and add epdm... I don't want to mess with the ice and water on the house... I was thinking to add metal down the transition onto new osb on flat roof.. Use a reinforced strip over seam of osb and metal. Then glue the rubber to the metal up the transtion 2 feet and bring shingles down about a foot...
If this is not a good idea... How would I seam the epdm and the ice and water on the slope...
