Question:

I have a 2007 enclosed trailer with a 1 piece aluminum roof with a corner bead. I think I am getting leaks at the roof corner. I see there is tape and self leveling sealant. Looking for advice on methods to reseal. Second question. If I have a pin hole in middle of roof, is the tape a good option. Thanks for your help,

Hey Andrew, welcome back! So there's basically two types of sealant. There's self leveling like the part # DC94SR and there's the non-sag sealant like part # 344270341437-1.

If the hole you need to fix is on the roof and on a totally flat surface it's best to get self leveling but if it's on the side or any non flat surface where self leveling would run off you'd need the non-sag. Butyl tape is more for sealing two things together like a vent to a roof and you want to basically make a gasket.
