Anyone in the world
Whenever possible, I park a dumpster close to the house to toss
in the old shingles right from the roof, simplifying the
clean-up. The first row of shingles — sometimes called the
starter strip — should overhang the drip edge by about a
half-inch.
Make sure to measure the height of your shingles and mark a line
on the underlayment where the top edge of the shingles needs to
be to get the half-inch overlap.
You’ll probably have to trim your starter course to get the tar
strip as close to the edge of the roof as possible.
