ROOF EDGE
• 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.
EAVE
Over Driven
1/32"
• 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.
• Aluminum expands and contracts with temperature changes. Failure to allow movement
can result in bulging or buckling when the temperature changes.
• Drill oversized nail holes and do not nail too tightly. Nail roof edge into place using
painted aluminum trim nails. Nails should penetrate the wood a minimum of 3/4"
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.
