What wavelengths of light would a laser need to be to leave blue roof tiles unharmed? Blue wavelengths, right? High power visible blue lasers are incredibly bright. Where's the videos with intense blue laser light burning everything down? We never see any ultraintense laser light in any photos or videos about DEWs. Curious that is the case.

I don't know if I believe it, but when my house needs new roof, it will be either steel or ceramic, and preferred color will be blue if available.

Just a coincidence that so many of the blue roofs happened to be metal instead of highly flammable asphalt shingles. People make me laugh.
