Hi, I’m redoing the roof on a small shed. I’ve helped with roofing jobs before but never done it myself, and the one thing I can’t seem to find the answer to is how to put down the first starter row. (Or there are too many conflicting answers). I have “architectural” shingles, about 40" long, with some extra 3-tab shingles of the same colour for the ridge.
What I’ve read is to cut the tabs off a 36" three-tab shingle and turn it upside down (?!). I don’t have 3-tabs for the purpose, so how do I cut down the architectural shingles and do I rotate them or flip them over? What seems logical is to have an shingle edge with a tar strip near the roof edge to help seal it. There seems to be cellophane tape covering an adhesive on the upper edge of the shingle and a tar-like edge on the bottom “toothed” edge. And four nails or eight per shingle for this row?
Also, do I fold the final row of shingles over the peak, or cut them before putting down the ridge?
Thanks for any help.
