I use lasers often for work. Target material properties drastically alter penetration (or reflection) depending on what laser wavelength is used.
Mirrored surfaces offer the best reflection (still dependent on the mirror’s material composition), but to say they’re the only way to reflect a beam is nonsense.
These people are stupid. The houses that didn't burn had metal roofs. One was red, one was blue. But this pyop was instantly on, " Oprah had a blue roof". Guess what the two houses have in common? They both have metal roofs.
Material composition of the roof is extremely important. I don’t have any experience with galvanized tin (which is most metal roofs AFAIK), but it isn’t on allowable materials lists for any CO2 or fiber lasers that I’m aware of. However, if they were steel roofs (just an example- not aware of anyone using steel for roofing), a blue-spectrum laser of sizable wattage would cut through it like a hot knife through butter.
That said, painting the roof a color that matches the wavelength of the beam itself would do more than nothing to reflect the energy. It wouldn’t be a perfect reflector, but it could substantially help compensate the energy that gets absorbed by the roof material.
Edit to add: material composition of the paint itself would also be an important factor.
I never quoted anything- that was never part of the discussion I partook in. Does anyone else hear circus music?
If you were asking politely & from a place of genuine curiosity, I’d happily explain the basic physics principles that would resolve your question. However, you type from a position akin to a 14-year-old who thinks they already knowing everything, and I’m perfectly satisfied with you basking in your own ignorance- especially if it saves me time to put towards to literally anything else.

I agree with you. It's the materials, not the color. But this color shit was almost instant.
Do you also regularly use space based laser cannons?
I addressed your asinine claim regarding lasers and mirrors. Attempting to deflect from that just makes you look [even more] like a clown.
Cool story Mr Laser Engineer.
Want to quote the thread title again and tell me that OP is right?
