• A 90 Degree, external corner Kerb corner, made from injection moulded Upvc for precision. Provides a neat finish to the roofing edge system.

• Available in Black or Anthracite Grey (white unavailable).

• Moulded to the same profile as the kerb trim, allowing a flush fit when putting in position.

The external kerb corner is designed to either:

• Continue kerb you roofline around a corner, or provide a neat return when the kerb edge meets a gutter edge

• Cover an external corner of two gutter edges which meet

More information can be found in the kerb installation guide, but to simplify: 

• Simply slide the external corner over the kerb where necessary on the roofing edge corner.

• Some Bond & Seal can be applied to bond the two together (before housing in position), or a Polypin/Delux Fastening can secure in place (pilot a hole first).

• A Large Corner Cap (sold separately) may be need to close any open end of the corner.

  • Do the corners get fitted after the kerb trim?
    Yes. Install your kerb roofing edge trim flush to the roof edge, then your external kerb corner will house on top of your kerb trim, continuing or finishing your roof profile as necessary.
  • What happens to an open end of the corner?
    Large corner caps are sold separately to be placed in any open ends. These caps can be held in place with Bond & Seal Sealant.
  • Can I use my own roofing edge trims?
    Of course, whilst we do advise our roofing edge trims as they're specifically designed for purpose, there are other options available, or you can create something bespoke. So long as you follow the principles of Gutter & Kerb edges for necessary water run-off into your guttering system, & don't cut the EPDM overhang too short, you're good to go!
  • Will the colour fade over time?
    Yes, slightly. Like most external material use, including UPVC, the combination of UV exposer & external elements will slightly affect the colour over time. This will not affect performance.

We strongly advise being present for delivery to inspect your products & sign delivery notes. Additionally, not all courier service trucks have tail lifts, or pallet trolleys. Please be prepared with the necessary person(s) to take delivery of your items, necessary for the size of the order.

Notes on the delivery of Elevate EPDM:

If you order EPDM with your items, the rubber will be delivered rolled up for ease of transport. As a result there may be some fold creases and wrinkles - this is normal. To remedy this, the EPDM should be laid to rest, or settle, for a minimum of 1 hour. In colder temperatures, the light use of a heat gun (not a naked flame) can be used to settle the rubber. Don't overheat or touch directly.

Starting your project:

We advise not booking in or arranging an installation team to begin works before the goods have been delivered & inspected. Delays or order mistakes are rare, but can happen. We can't be liable for any costs as a result from delayed or incorrect delivery or items.
