Roof Service Entry

Weatherproofing penetrations for pipe and cable entry in flat roof plant areas

Roof-Pro risers provide the building team and service engineers a consistent quality solution for necessary penetrative details on flat roofs.

PP-3 and Roof-Nek offer increased assurances that the cable and pipe access points will be efficiently watertight and insulated. The design allows M&E trades easy access to run cable and pipes. Once installed, the building is immediately dry, and following trades can fully access the riser by temporarily removing the lid. The vapour seal should be made at deck level.

PP3 Roof Service Entry

The Roof-Pro PP-3 access riser provides a watertight entry point to run larger cables and pipes into your building. It is the larger of the two riser details and is available in the following sizes.
