Yes, that's a very physically demanding job. You've got my respect.
Can you hire any teenage boys to help? They are the ones with energy.
Sometimes no direction, but lots of energy.

Years ago, a friend showed me that on the long flat edge of the
shingle is a cut. You find that cut, and that's where the short edge
of the next shingle lines up.



That depends on the type of shingles being used. Three-tabs and "shangles"
(those three-tab shingles designed to look like shakes) it is important to
line the shingles up correctly so that the cutouts line up every other row.
On architectural/dimensional shingles, it doesn't really matter.




Actually, shingle manufactures suggest that the
cutout line up after more than every other row, to
minimize streaks and rain groove wear. I followed
the instruction on the package and mine line up
every third row. Most roofers in my area follow
that pattern.
