We’ve been looking at this for a while. We get asked a lot of times for windows in the roof or can you fit something like a Velux window in the roof of your Log Cabin.
The answer is yes you can. But to fit a velux requires a lot of modification, a lot of strengthening and a bit of mucking about. They can be fitted but it’s not a fun job.
This is a cracking new product we have added, it seems to tick all the boxes, it’s easy to fit, light enough to not worry about extra strength and provides a good lot of light into your log cabin.
You can see there is a huge difference. The skylight is easy to fit on a fresh install but you do need to base it around a felt backing, the surface that the oil based compression gasket seals onto needs to be relatively smooth, standard shed felt or EPDM or Easy roof membrane is ideal. If you have a shingle roof you will need to have an area of felt only.
Installation of the skylight / roof vent is very straightforward and you do not even need to be on the roof. Installation as a retrofit is a little trickier and I will be doing this over the next week or so and posting on this on the way I think it is best done.
As well as a normal roof you can also install this on an insulated roof, it may though be necessary to add additional trim around the rim of the unit.

Installed with an insulated roof. Longer bolts may need to be sourced locally and also trim for the inside.
