RoofSafe,
I have the un-advantage of being 6'-5". I have troubles seeing the eyes, I snap lines 5 3/4" - 11 1/2" - 23" - 34 1/2" - 46" -
57 1/2" then set brackets. Pretty methodical but it's how I do it. Lines bottom to top never fail me as to matching the courses once I get above the obstacles and more than one roofer speeds up the process.
We use drip up here so the first 4 course are put on by matching top of cut out (3 tabs get lines every course).
Oh, or valleys are the fastest I have seen and once someone does this they never go back.
1. Weave lower pitch or smaller roof up normally. Sweep valley and snap line directly up center of valley.
2. Lay a course bottom edge to the line up the valley (works only with archs) cris-crossing one side with the other at ridge further protecting caps as they dive small ridge to main roof ( sometimes these dry and crack).
3. Main roof run plane to the valley, cutting shingle (square in length) bottom corner up (with hooker).
Valley Done. No hard cold cutting, no too deep cuts with hot summer buttery shingles and very straight!
