I have built an openable insulated box to house a pump for an outdoor spa. The lid opens fully +90 degrees and leans against the edge (see dotted line). The plan is to cover the lid with roofing sheet metal (black area in the image), but I do not have a good solution to make it rainproof at the hinges (circled on the right in the image). I first thought of roofing felt starting from the wooden box to the right and "laying over" the sheet metal, but that probably won't hold after several folds. Grateful for ideas and pictures.

Diagram showing an insulated box with an opening lid for an outdoor spa pump, featuring areas for rainproofing near hinges, marked with dotted lines and a circled area.

Remove the edge as support and use a type of steel wire instead that holds the door when it's open. Then you can make a roof that covers the entire door with hinges on the outer edge. Additionally, you should make a slope on the door/roof to the right so that the water drains off safely.

Thanks for the response. Yes, the hatch tilts a bit to ensure drainage. Even if I place the hinges on the innermost part, the issue with water will remain, i.e., it will flow into the construction. I need to create some form of rain protection over or on that part. I'm thinking of something like a flap or similar, or am I thinking completely wrong?
 
No one else who has any clever ideas on how to solve this?
