Small Diameter Roof Drains

Flat Roof Gutter Drains

Allproof Small Diameter Roof Drains are purpose-built for flat roof and low-slope roof applications, providing a premium, space-saving drainage solution for internal gutters and narrow roof areas. Designed with a compact bronze flange and mechanical clamp system, these drains deliver exceptional waterproofing performance and long-lasting reliability.

The drain’s flange is recessed into the roof substrate and securely fixed with stainless screws. The roof membrane is dressed over the flange and clamped with a precision-engineered ring, ensuring a durable seal that resists building movement and weather conditions. A cam-lock grate allows for easy maintenance without disturbing the waterproofing layer, protecting the integrity of the installation.

Features:

- Bronze flange rebated into roof substrate for stability.
- Waterproof membrane mechanically clamped with stainless steel screws.
- Cam-lock grate for maintenance without disturbing the membrane.
- Outlet fits inside pipe riser with O-ring seal (50mm, 65mm, 80mm, 100mm).
- 88° outlet option available for 50mm and 65mm pipes (skillion roof solution).
- Independently flow rate tested for performance assurance.
