Starlink Flashing Mount Installation

A flashing mount provides a roof-penetrating installation for Starlink dishes with integrated weatherproof flashing. This guide covers flashing mount types, roof pitch compatibility, and waterproof installation on UK roofs.


A flashing mount is a roof penetration system that replaces a roof tile and provides a sealed pipe entry for the Starlink dish mount. The flashing plate slides under existing roof tiles creating a watertight junction. The Starlink flashing mount consists of a lead, aluminium, or rubberised flashing plate bonded to a pipe section. UK roof compatibility is important -- UK roofs typically use interlocking concrete tiles, clay plain tiles, or slate. Lead flashing mounts are best for uneven roof surfaces (slate, plain tiles) because lead is flexible. Aluminium flashing suits interlocking concrete tiles. Universal rubber flashing mounts fit most tile types. Flashing mounts work on roof pitches from 15 to 60 degrees. The mount pipe must be at least 500mm above the roofline to clear snow and provide clear sky view. Pipe diameter must match the Starlink pipe adapter at 48mm (1.5 NPT). The official Starlink flashing mount costs £89 from the Starlink shop. Third-party options from Pole Mount UK cost £60-£90.


Installing a Flashing Mount on a UK Roof

Step 1: Select the roof location. North-facing roof pitch is ideal. Check for clear sky view from that area. Step 2: Remove the roof tile at the installation point. For interlocking tiles lift the tile above to release the lock. For plain tiles slide the tile up. Step 3: Mark the rafter position. UK rafters are typically 50x150mm or 50x175mm at 400mm or 600mm centres. Step 4: Cut a hole in the roof sarking felt for the pipe. Step 5: Slide the flashing plate under the tiles above the hole. The flashing should extend 150mm above and 100mm each side of the pipe. Step 6: Attach the mount to the rafter using stainless steel coach screws. Step 7: Seal around the pipe with butyl sealant or exterior silicone. Step 8: Replace any tiles, cutting around the pipe if needed. Step 9: Inside the loft install a roof cable entry gland to seal the cable exit. Step 10: Route the cable to the router. Staple to rafters using cable clips. Step 11: Attach the Starlink pipe adapter and dish. Step 12: Check for leaks during the next heavy rain. Prices: official flashing mount £89, lead flashing £70-£100, rubber flashing £45-£65, professional installation £200-£350.

FAQ

What is a Starlink flashing mount?
A flashing mount replaces a roof tile with a pipe penetration that includes weatherproof flashing. The pipe protrudes through the roof and the Starlink dish mounts on top providing a waterproof roof penetration.
Do I need a roofer to install a Starlink flashing mount?
A competent DIYer with roof access can install rubber or aluminium flashing mounts. Lead flashing requires a roofer because lead needs to be formed to the tile profile. Professional installation costs £200-£350.
Can a flashing mount be installed on any UK roof pitch?
Flashing mounts work on roofs with pitch 15-60 degrees. Very flat roofs under 15 degrees and very steep roofs over 60 degrees may need custom flashing solutions.
Will a flashing mount leak if not installed correctly?
Yes, incorrect flashing installation is the most common cause of roof leaks from dish mounts. Always seal with butyl sealant and check after heavy rain. Lead flashing must be dressed properly to the tile profile.
What is the difference between a flashing mount and a ridge mount?
A flashing mount penetrates the roof slope while a ridge mount attaches to the roof ridge. Flashing mounts are less visible but ridge mounts provide a higher position. Flashing mounts are easier to weatherproof. For more information see our Starlink Ridge Mount Installation.
