Retrofit Spin Flashing Specification

So that you may be assured of receiving the fine quality you expect when you specify All Style Industries Retro-Spin Flashings, we include the following sample specification for your convenience.

All Style Industries' Retro-Spin Flashings are fabricated in the United States from first quality electro-galvanized sheet metal. The life expectancy of a Retro-Spin Flashing should exceed 20 years. A Retro-Spin Flashing is a roof jack, or pipe flashing, which waterproofs roof penetrations when an "over the top" installation is not possible or desirable. It is useful for "from the side" retrofit installations.

A Retro-Spin Flashing assembly is constructed of one tightly fitted interior and one exterior impact extruded roof jack flashing. The patented Retro-Spin design enables the interior flashing to rotate freely within the confines of the exterior flashing. Pre-punched access slots are cut through the sides of the two flashings creating a "door" that opens and closes using the spin action design.

Choose the Retro-Spin Flashing design that is large enough for a roof penetration to pass through the open slot and enter the conical interior of the jack, allowing the flashing to rotate, or spin closed without obstruction. Hand tools are not needed when placing a Retro-Spin Flashing around a roof penetration.

Retro-Spin Flashings are fabricated from single sheets of metal with no attachment seams. The flashings' conical shaped cones are three inches high. A four inch horizontal flange, or skirt, is formed for the final attachment to the roofing system. The diameter of the conical opening of a Retro-Spin Flashing is three inches.

A variety of pipe sizes and geometric shapes can be flashed, and waterproofed using the Retro-Spin Flashing. An optional accessory, the patented Retro-Split Storm Collar can be used to attach to the roof penetration and counterflash the Retro-Spin Flashings' conical opening. The combination of a Retro-Spin Flashing and Retro-Split Storm Collar creates a waterproof flashing assembly for any combination of multiple pipe or odd geometric-shaped roof penetrations.

For roof slopes greater than 4 and 12, spin the interior flashing 180 degrees to the "closed" position and align the door cut-out so that it faces "down hill" to the roof slope. For roof slopes less than 4 and 12, caulk or solder the seams of the door cut-out for added security.

For flat roof installations, always use good soldering techniques to seal the door cut-out after it is closed. (See image)

As with any roof jack flashing, refer to the
roof system manufacturer, or to the National Roofing Contractor Association's (NRCA) roofing manual for the proper installation details for your roofing system.
