Flat Roof Hopper Half Round

Description

Flat Roof Hopper – Half Round, Copper and Titanium-Zinc, With or Without Overflow

Protec manufactures a flat roof hopper (flat roof water collector) in a half-round form, available in copper and titanium-zinc. The semi-circular profile sits flush against the facade, creating a clean and harmonious appearance in combination with a round downpipe. Available in two variants: with overflow (for additional drainage safety on flat roofs) and without overflow (for a simpler, cleaner installation). Produced to order with a flexible rear downspout connection – position, shape, and size specified per project.

Application – Where to Use a Flat Roof Hopper:

The flat roof hopper half round is specifically designed for flat and low-pitch roof drainage – connecting the horizontal roof outlet to the vertical downpipe while maintaining a clean facade appearance. Particularly suited to:

  • Small extensions and lean-to additions – where the drainage connection must be compact and unobtrusive
  • Outbuildings and agricultural buildings – garages, sheds, barns with flat or slightly pitched roof sections
  • Parapet (attika) drainage – flat roof sections of residential and commercial buildings with parapet walls
  • Combined roof systems – buildings with both pitched and flat roof sections requiring matching drainage components

Two Variants – With and Without Overflow:

With Overflow:

The overflow version includes an emergency drainage outlet that activates when the primary downpipe flow is exceeded during heavy rainfall – preventing water from backing up into the flat roof drainage layer. Recommended for all flat roof installations where additional drainage safety is required.

Without Overflow (Ohne Zulauf):

A clean, simple form without overflow – suitable where overflow protection is integrated elsewhere in the roof drainage system, or for smaller roof areas with lower drainage volumes.
