Looking for some advice re: rainwater dripping from metal plastisol coated edge trims to garage roof (as you can see from photos). What would be the best way to resolve this ? I was planning to use an external silicone sealant along the joints to try and stop the capillary action. Any thoughts or advice appreciated.
