Drainage to Single Ply Roofs - Application Guidelines

Roof Drainage

Ponding water will not have any detrimental affect on the Monarplan PVC single ply roofing membrane, however it is recommended that roofs be designed with falls (minimum 1:80) to remove water from the roof. To achieve this a design fall of 1:40 / 1:60 should be considered.

All areas of the roof and the gutters / valleys have to be sufficiently drained. The corresponding number of rainwater outlets and overflows as well as their adequate diameter shall be ascertained prior to application of the Monarplan system.

Gutters

Gutters can be lined using Monarplan single ply membrane in conjunction with Monarplan coated metal.
