Description
Refurbishing a flat roof often means dealing with an outlet that has corroded, cracked, or simply outlived the waterproofing around it.
This aluminium refurbishment drain outlet is built for exactly that moment: a robust, corrosion-resistant replacement that secures into an existing outlet position without demanding the full disruption of a new-build install.
Where a membrane-bonded outlet is fitted as part of a fresh EPDM installation, this outlet is designed the other way round — for commercial and larger domestic flat roofs where the waterproofing is being renewed or repaired around drainage that already exists.
It gives roofers and facilities teams a dependable way to bring ageing drainage back up to standard. Installing a new membrane from scratch instead?
Our Vertical Threaded Dome Grate Outlet is the bonded, new-build version, in 4 sizes from 50mm to 150mm.
Key benefits
- Durable aluminium construction, engineered to withstand sustained exposure to UK weather
- Locating lugs and fixing rings hold both a gravel grate and a leaf guard firmly in place
- Purpose-built for refurbishment and retrofit work, not just new-build installation
- Keeps leaves and debris out of the downpipe while maintaining strong, unrestricted flow
Suitable applications
Commercial flat roofs, warehouse and industrial buildings, and larger domestic flat roofs undergoing refurbishment or re-covering — anywhere an existing rainwater outlet needs replacing to match a renewed waterproofing layer.
Specification
- Material: Aluminium
- Downpipe connection: 75mm
- Included fixings: Fixing rings for gravel grate and leaf guard
Installation & ordering
The outlet fits into the existing outlet aperture and connects to the downpipe before the surrounding membrane or waterproofing layer is dressed in around it. Please confirm your existing downpipe diameter before ordering.
If you're integrating this outlet with an EPDM membrane installation, our drainage and installation guides can help — or get in touch before ordering if you're unsure which outlet is right for your roof.
