Blue tile roofs are common in tropical areas and are the choice of many high end resorts. I have three homes in my neighborhood with blue roofs and I live in the foothills in California. Biden was stating what everyone has known for decades and that is tile roofs and slate roofs are all superior to wood shingle or cement composite roofs when it comes to spark resistance and wildfires. Start looking for arsonists and stop with the DEW crap already.

In Lahaina, blue roofs saved very few homes from the "fires". Most were taken out, obliterated to dust by a force more powerful that a stormy, wind-fueled fire. Lahaina was attacked by Directed Energy Weapons. The devastation of the lovely town is the proof.
