wait until you learn about 'engineered beams'

I shudder thinking about all the structures built with those things that're one undetected bathtub drain leak away from serious structural failure.

I'm confused. Do you have evidence that an engineered beam will fail faster due to water damage than a beam made from 2x4s?

Weatherproof LVLs are actually much more water resistant than a regular solid piece of pine. Even indoor engineered beams are quite water resistant.
