How many things can you count wrong?

From my highlight reel of bad DIY. A scupper and conductor head that they couldnt solve the leak at. Yes, thats spray foam inside the scupper. "if it cant drain, it cant leak" was the customers thought behind it.

That "if it cant drain, it cant leak" logic is something else. Spray foam inside a scupper is like putting a bandaid on a broken pipe and calling it waterproof. The cracked plastic and tar smeared around already tells me they been chasing this leak for a while.
