INSTALLATION GUIDELINES
L-FLASHING
Typical Sidewall L-Flashing Detail
used with larger L-Flashings
L shaped flashing is a versatile, general use flashing used where
a uniform or strengthened finish is needed on a 90 degree
surface.
L-Flashing and Step Flashing should be nailed to the sidewall, not
the roof deck. This avoids making holes in the roof deck and
allows the flashing to move with your house.

Begin installation along the eaves, starting at a corner and
working your way around, overlapping each succeeding piece of
drip edge by 2-3 inches.
After the eave drip edge has been installed, apply the underlayment and/or ice-water barrier.
Once the underlayment has been installed, apply the drip edge to
the rakes. Make box corners by wrapping the rake edge around
the eave metal.
Depending on local building
codes and wind conditions,
roof edge should be nailed
every 16 in. - 24 in.

CAUTION! Working above grade is inherently dangerous, be sure that proper fall protection measures are in place.
When working with power tools and sheet metal, gloves and eye protection are absolutely required.
These installation guidelines are for use with typical or standard applications. It is always recommended to seek advice from a licensed professional, and to
check with your local building inspector or building permit office for approvals and possible variations that may apply.
