Installation Instructions
Retro-Spin Flashing 2 of 2
Move the Retro-Spin Flashing to the roof penetration on the down slope side of the
penetration. Pass the penetration, uphill, and inside the Retro-Spin Flashing. After the
roof penetration is within the confines of the Spin-flashing, rotate the assembly 180
degrees. The action of rotation closes the door and surrounds the penetration. The doors
should be on opposite sides of the flashing assembly with top cut out facing down slope.
If the cut out is facing up-Slope rotate the assembly so the flashing faces down slope.
Never install the Retro-Spin flashing with the top door cut out facing up hill.
Center the Retro-Spin flashing on the roof penetration. With the door closed, and the
assembly at 180 degrees face the door in the direction of the down slope of the roof deck.
If the roof slope is greater to or equal to 3″ and 12″, no sealant or caulking is required at
the closed door. On roof slopes below 3″ and 12″, inject a small amount of paintable
caulking between the inside and outside flashings. On dead flat applications, solder shut
the open door to create a watertight condition.
Now use the manufacturer’s recommended procedures for installing a roof jack flashing
into the steep slope-roofing product, and securely nail the Retro-Spin Flashing into place
using 3/8″ flat head roofing nails. Use nails long enough to penetrate through the Retro-
Spin Flashing and into the roof deck a minimum of ¾″. Pre-punched nail holes provide
placement guides for the fasteners.
Continue the installation of the roof system. Apply paint to the Retro-Spin flashing to
match roof color and protect the metal.
All Retro-Spin Flashings include a 3″ diameter opening, and since not all roof
penetrations fit snugly, it is necessary to counter flash the penetration using a waterproof
EPDM Retro-Split Storm Collar.
