In 1993 I lived in Laguna Beach CA and a wildfire combined with high air temperatures and fast Santa Ana winds roared through our town. We lost no lives thankfully but our town lost 366 homes, 50 of which were on my street. I was renting at that point and gathered my things and left early. When I returned most of the homes on my street were burnt to the ground. My rental was still standing in a row of 3 homes that made it through the fire. My neighbors to each side of my place had stayed and watered their roofs until the fire department could get to them. Ours were the only 3 homes that made it in this section of our street. I don't recommend staying during a wildfire but my neighbor's efforts to water their roofs and mine made me realize that I could have an impact on the chances of my home surviving a fire.I have uploaded a video you can watch that shows me doing a trial run on the sprinklers you are considering here. I highly recommend this product as it is well built and easy to install. The product designer/company owner was very helpful to me by phone. A few points to consider: He recommended a hot water hose to connect the sprinkler as they are more durable. I purchased a 50 foot hot water hose at Home Depot. I was tempted to purchase a metal wrapped hose but he let me know that the actual diameter of hoses of this type are generally to small.I also found some textured spray paint to make my sprinkler blend in with my roof shingles. This was easy to do, I suggest covering the sprinkler head during this process. My sprinkler is working well and I have ordered another to put at the other side of my roof. I highly recommended this product.
