Install J-Channel

What happens here

Install J-channel around the perimeter of the building where metal siding will meet other surfaces (e.g., soffits, windows, doors). J-channel acts as a trim piece and a crucial component for weatherproofing, directing water away from the underlying structure. Carefully cut and fasten the J-channel to create a clean, finished edge for the metal siding. This will hide any imperfect cuts in the siding panels and ensure a watertight seal.

Goal: Create weather-tight and aesthetically pleasing edges for the metal siding.
