Eaves Flashing

Gutter eaves flashings are not required for weatherproofing unless the building is in a very exposed location and the eaves are not protected by spouting. They can, however, serve a purpose in many applications of improving the durability of roofing at the eaves.

The flashing should extend into the gutter, and the underlay finishes on the down-slope of the flashing. If there is no over flashing to the gutter, the underlay should be extended into the gutter by a maximum of 20 mm.

Unwashed flashings should be made of durable materials such as organic coated steel, aluminium, or PVC.

Eaves flashings as referred to in E2/AS1 are not required for weatherproofing unless the eaves are unprotected by spouting, but they can make a contribution to durability.

Eaves flashings are recommended in Marine Environments to improve the durability of the roof cladding, and are required for pre-painted aluminium roofs (see 14.9). Eaves flashings may be pre-painted steel or aluminium (either pre-painted or uncoated). To minimise the build-up of salt deposits at the eaves, a high fronted gutter fully covering the roof crests, attached closely to the fascia, is recommended in Severe and Very Severe Marine environments.
