Under-gutter flashing

Eaves flashings

Eaves flashings are one of the most important technical details of a roof, responsible not only for the aesthetic finish of the roof edges but, above all, for the proper functioning of the entire roofing system.

The most important functions of eave flashings include:

• Effective drainage of rainwater and meltwater into the gutter system,
• protection of the roof layers against capillary seepage,
• protecting the eave structure, fascia board, and facade from moisture,
• ensuring the roof coverings are watertight in the eaves area,
• protecting the roof deck from rain, snow, and strong winds being blown under the roofing,
• ensuring proper ventilation of the roof surface,
• draining condensation and moisture from the pre-covering,
• to increase the roof’s durability and operational safety.

Special attention should be paid to ensuring that the eave flashings are properly connected to the roof membranes, the gutter system, and the ventilation components. An improperly installed eave detail can lead to moisture penetration in the thermal insulation, deterioration of the wooden structure, and reduced effectiveness of roof ventilation.

Under-gutter flashing

Under-gutter flashing is a roof covering component designed to protect the roof surface and the building’s facade from water seepage. In particular, it protects the fascia board to which it is attached, as well as the building’s wall, from the effects of rain, especially during heavy downpours. To ensure the roof functions properly, especially in the eave area, we recommend the assembly of other eaves flashings alongside the GUTTER BAND, including the OVER-GUTTER FLASHINGS from our product line:
