8" Galvanized Roof Flashing

This galvanized roof flashing fits single-wall pipe with an 8" diameter. It adjusts from a flat profile up to a 5/12 roof pitch for versatile installation. The steel construction resists corrosion in outdoor conditions. Builders sealing roof penetrations will find the adjustable angle useful.

Capacity and headroom

The flashing covers an 8" pipe opening and handles pitches up to 5/12 without modification. Steeper roofs exceed the built-in adjustment range and need a different solution. Installers must apply caulking or roof tar on all seams to complete the weather seal. It is not suited for double-wall or insulated pipe systems.

Questions about this item

Will the 8" galvanized flashing GV1387 fit my existing single-wall pipe without modification?

Yes, the flashing is made for single-wall pipe and adjusts from flat up to a 5/12 pitch so it matches the roof angle you already have.

How can I confirm the GV1387 flashing is sealed correctly once installed?

After fastening, apply caulking or roof tar to every seam; a continuous bead with no gaps shows the flashing is working as intended.
