ᐅ How do I properly reseal the roofing membrane?

Hello

we need to cut through the roof membrane to route a cable for the roof window blind.

After connecting the cable to the roof window blind, how do we properly seal the roofing membrane again?

What is the correct way to do this?

You need a cable flashing collar or something similar, right?

Where can we get something like that and what is the correct term for it?

Try searching for cable sleeve, for example Kaflex, Kaiser, etc.

Which one would you recommend more? Kaflex?

Are they also available in sizes larger than 14x14cm (5.5x5.5 inches)?

I use Kaflex and am very satisfied with it. I don’t think it comes in a larger size. For cable penetrations, you only need a small hole. For larger installations, it’s better to seal again with Siga tape.
