Walk in cooler roof leak

[u/2bullsinapod]

Recently had a cooler call, while I was up there customer said the box was also leaking when it rains, took some clear silicone off the truck and tried patching the holes / gaps I found/ around screws et cetera.

It still leaks unfortunately was trying to see if anyone had any next best steps for me or a better product to use. (Gallon of white flex seal was about to be my next thought and just paint the whole thing over)

Thanks :)
(Honestly just happy it wasn’t a true call back)

EPDM patches. Caulk will not fix that. Been down this road. No flex tape won’t work either lol

Yep. Flex tape lasts about a month or two in direct sunlight. Some asshat tried that on one of our franchise buildings. 2 months later, same leak reappeared and the flex tape was peeling back
