Redland: Guide to Cabling Through a Roof

Redland: Guide to Cabling Through a Roof

The increase in roof-mounted components for satellite, broadband and PV installations poses a challenge in terms of cabling into the building. However, the answer is at hand as Damien Pooley, Components Manager, Monier Redland, explains.

Every home is cabled and many of these cables need to go through the roof in some way. A range of specialist adaptors from Redland are now available that are specifically designed for the task combining with its interlocking tiles in a seamless way.

The result is a great fit that matches the surrounding tiles and comes with the Redland assurance for quality.


The ‘make do and mend’ school of thought is content to drill a hole in the roof tile, seal it with silicone sealant and hope for the best. But a purpose-designed product, which has actually been properly tested to the appropriate standards, will perform far better and provide the assurance there will be no issues in future.

The Redland outlet adaptors are modular, so they need no special tools, and are specific to various uses, such as aerials, solar and telecoms.


1) Position base tile to avoid roof rafters and mark underlay with a ‘cross’ at centre of opening. Cut cross with a Stanley knife or similar to allow cables or aerial post to pass through.


2) Seal around the cables with a cable seal. Stick to underlay in a diamond orientation.


3a) Cable Outlet Adaptor

Push adaptor onto base tile and snap into place, ensuring all 4 tabs are engaged. Cut one block off blanking strip for each cable being used, and insert into front channel. Then, with cables in position, add the foam strips and adaptor cover and screw into place.


3b) Solar Outlet Adaptor

Pass the large cable through the adaptor and snap the adaptor into place. Cut the end of the rubber gasket to suit the size of the cable. It should be a close fit to provide a weathertight solution. Push the gasket firmly onto the adaptor.


3c) Aerial Outlet Adaptor

The Aerial Adaptor, for fixing aerials or satellite dishes, comes in two parts. Attach the top part one way round for a lower roof pitch range or the other way round for a higher roof pitch range – i.e. so that the outlet is as vertical as possible. Snap the antenna adaptor onto the base tile with the outlet vertical.
