INSTALLATION GUIDELINES DRIP EDGE/GUTTER APRON Aluminum flashing expands and contracts with temperature changes. It must be "hung" rather than "attached" to accomodate this movement. PRE-DRILL HOLES Over Driven 1/32" KE RA DRIP EDGE GUTTER APRON EAVE 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/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 wind conditions, roof edge should be nailed every 16" - 24". 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.
