Hello, what is the best way to fix this roofing problem? For example, should I leave everything alone and just nail one hip shingle over the one that tore off? Should I shave off shingle C and then hammer in a new shingle beginning with where B ends with on overlap? Ideally, I think it is better to lift up A and B and put a new shingle under B and over D. However A and B are nailed down and I do not want to disturb them if it is not necessary. I am also concerned about damaging them.
Should I use more than one shingle? If so, what is the best way to do it?
I will be using IKO Ridge/Hip shingles that go with IKO Cambridge shingles. I plan to do the work around noon on Thursday, a 70 degree day.
Thank you so much for your help!
