Drip edge at eaves shall be permitted to be installed either over or under the underlayment. If installed over the underlayment, there shall be a minimum 2 inch width of roof cement installed over the drip edge flange.
I looked at some new construction rough-ins and noticed they install the drip edge at the eaves over the felt. I came back later and no tar was applied. Maybe, this is because I live in a warm climate where no ice forms. If I install it over the drip edge, I do not need to seal the shingle to the felt with tar. What is a better method? Should I do over the felt for the rakes and under for the eaves. No ice and water will be installed because of the warm climate.
