PP3 & ROOF-NEK
The Roof-Pro risers provide the build team with a prefabricated detail providing a consistent level of quality and design for weather-proofing penetrations for pipe and cable entry in flat roof plant areas. They avoid DIY attempts often seen onsite that become weather-proofing nightmares, and clearly defines the space and route available for pipe and cable entry.
The PP-3 and Roof-Nek offer increased assurance that cable and pipe entry points can be effectively water-proofed and insulated by the roofing team. Once installed and weathered the building is immediately water-tight, and the M&E contractors can at a later date fully access the riser by temporarily removing the lid. The design then allows easy access to run cable and pipes through the mid-section into or out of the building.
The pipes and cables also exit the riser detail at the ideal height to be supported by Roof-Pro's pipe and cable supports, and allow for future roof maintenance access under the services.
PP-3
The PP-3 unit provides a water-proofed entry point to run larger cables and pipes into your building. The PP-3 is the larger of the two riser details, and is available in 3 standard sizes and bespoke sizes on request.
Features
The PP-3 is made for waterproof durability encompassing an easy access design which includes:
- Powder coated aluminium finish – for durability.
- Pre-primed base section – for quick installation into the waterproofing membrane.
- Cover flashing – deep enough to permit vertical insulation.
- Removable access lid – gives clear working access for M&E contractors.
- Aluminium pull-out panel – cut without risk of corrosion to services profile for added weather protection.
- Future proof – upstand height sufficient for future waterproofing under services without decommissioning.
- Cowl projects over vertical aperture for weather protection.
Availability
PP-3 3040 (300mm high x 400mm wide vertical aperture)
PP-3 2020 (200mm high x 200mm wide vertical aperture).
Bespoke sizes of PP3 are available on request.

Features
The Roof-Nek is made for waterproof durability encompassing an easy access design which includes:
