I will be ripping the shingles off my home and was thinking of just covering the previous valley flashing with Ice And Water Shield. Would this work if I filled the current nail holes with roofing tar?
My second option was to tear out the old flashing and just put in a Ice And Water Shield than weave the shingles over the Ice And Water Shield in the valley.
In your experience what is the best way of doing this?
Thanks I am new to roofing.
