What web site is there that shows how to pop lines for running shingles, and other tips for roofing?

Answer 1

can't help you with a website, but... use aluminum drip edge atop felt paper (start at lowest point with felt, hand-nail every 12", 3 horizontal rows per piece). 1st shingle is upside down (to allow tar tabs to seal starter row), then measure reveal (distance vertically from bottom of shingle to top of shingle keyway), pull measured distance up on opposite ends of roof- pop lines. allow 3/4" to 1" overhang of 1st shingle over edge of roof to allow water to run into gutter and not behind fascia board. nail shingles 1" above tar strip, 4 nails per. Good luck!
