We have an 11 year old house that is already due for a roof. I'm getting tired of picking up shingles out of the yard after every windy day. At my last house I did a complete tear off and re-shingle. Tonight while we were picking out the color of shingles that I will be installing on the house I came up with a question. Hopefully someone can answer this. I am not doing a tear off, I am going to shingle over the existing thin shingles. Do I need to have a starter row of shingles turned backwards the first row like you do on a new roof? I hope this makes sense. I'm assuming I don't since I am covering over existing shingles...Am I right? Also we are going three dimensional. Thats what we did at our last house.
Thanks!
