Cut Old J
Flashing ~ When replacing an old roof, it is best to remove the
old flashing also. This flashing in the picture to the right is
called J Flashing. It is made in an L shape with a J loop on one
side designed to funnel the water to the bottom of the flashing.
It very rarely works in this manner mostly because the roofer
has to install the shingles
overtop of the flashing. Since the J Flashing is nailed 5" under
the siding it is practically impossible to take out so we find
that cutting it at the crease is the best way to remove it.
Tin Shingles
~ The flashing Systematic Roofing likes to use after the old J flashing is
removed is called Tin Shingles (step flashing). They can be manipulated
and cut to fit precisely into your homes siding creating a virtually
impenetrable barrier.
Overlapping
~ The way to install this product is to stuff one end under the siding and
the other on top of the shingle. Then, the next shingle will go on top of
the flashing and the next tin shingle will go on top etc., etc., etc.
Hence the nick-name, Step Flashing.
