ᐅ Creating Roof Overhangs Using Plastic Panels

Hello everyone,

I am currently considering how to cover the roof overhang for our new single-family house. On the gable side, we have two rafters extending outwards (total overhang without cladding and insulation layer = 50cm (20 inches)). Please see the attached pictures.

Is it advisable to attach plastic U-profiles, for example from a company like Heering, directly onto the rafters and then install plastic panels on the rafters? Or would it be better to install a sub-batten system, so that the rafters remain visible later on? For which option do I need to ensure ventilation behind the cladding?

I look forward to your suggestions and ideas.
Thank you and best regards,
Julian

First of all, this is an aesthetic question. The rafters are a clearly visible structural element. It’s actually a shame that wood wasn’t used between the rafters from the start. I wouldn’t worry about moisture getting trapped, but I would briefly consult with the roofing specialists.
My initial idea is to paint the gaps – matching the color to the house.

Pro: Better appearance
Con: The rafters would then also need to be painted regularly

How could I add an intermediate battens here to attach the plastic panels?

Wood protected from rain only needs to be repainted when it no longer needs to be cared for. Unfortunately, the cladding between the rafters is missing.
I would clad it from below, matching the house with wood or panels.

Would it still be practical to build the formwork now, as an additional step?
