Windows leaking

[FarmerSid]

Hey all! Spring looks like it's here as well as the rain. Last summer I built a 36X72 barn/shop. I have yet to insulate and am glad I didn't. I sheeted the exterior with green steel and white trim. I used vynil "J" trim around the windows and doors. I have noticed that rain is getting inside the walls at the vertical ends of each window. It appears that where the steel was cut at a 90 degree angle to transition from horizontal at the top of the window to vertical going down the window is where it is getting in. Does anybody have a solution for this? I have to get this fixed before I can insulate.

Thanks for the help.

If the rain is getting under the J molding, between the molding and window. Use silicone caulk around the J molding. You did not miter the top of the J molding I hope. It should go across the top and the bottom of the molding should be cut a little past the vertical J moldings to allow rain to run down the sides.
