ᐅ Transition from Gutter to Patio Roof Covering

Hello everyone,

I am currently building a covered terrace attached to our single-family home (bungalow). We are fixing the support beams of the roof to the rafters of the house, so the covering starts right below the gutter. This creates a small gap between the house gutter and the double-wall polycarbonate panels of the roof.

Surely, something would only get through in strong wind, but I still want to seal it properly. My first idea was to install a wooden cladding between the soffit and the support beam. However, there might be more elegant solutions?

I was thinking of some kind of flexible rubber strip or something similar that hooks onto the gutter and presses against the double-wall panels. Does something like this exist, or has anyone completed a similar project?

Thanks for your feedback and good luck BrosBrosBros
