" Now originally a bungalow like this specially catalog house like this would have had a light weight wooden shingled roof. And in California as these wear out you really can't replace him again because there a fire hazard. It's allowed in some historic district but right here where we are most houses get either a traditional asphalt or fiberglass shingle or something special like this we still have a few houses like the one across the street that has a wooden -- but let's go around the back climb back up -- and hooked up with -- so we can see how we install the product. OK -- Courtney this this party slate is that really attractive looking roof. From a distance it looks like a true naturalize green slate. But. It's a manmade product what did it you know guys Portland cement -- into their wood composition. I as the Portland cement makes it. Fireproof does have fire rating to death it's a classic fire rated product understand just a little over 200 dollars -- where the bottom material. And of course installed that would be more what kind of insulation to limited you have here were kind of conditions with the previous roofed. Which. I mean there were several groups went -- idea that you have actually there full. There. It was an old wood shake roof yeah and there are three feet pastel composition. Tell me for. A load on kind of a structure was holding up that load -- must admit it. -- Sagging actually about seven and a half inches from the artists out there right what what kind of sheathing it was on the -- Original 1920s. That's -- heaters that opens. How are you installing it -- the felt. I'm used to seeing thirty pounder fifteen pound felt in a double coverage. And here seem to have just eight or ten inches to the weather what kind of felt as this well this is thirty -- asphalt. Well and it's just it's just a teenage roles eighteen inch rolls. There. They get laughed as you move up to the second course about. Both in inches. And that that allows them more water. And so you put down a starter course. Which is just the same material in three foot lengths. And of course starter course builds up -- the edge of the roof to shed the water better and make for a sturdier to the exterior application. You -- and and it you can nail right through this that you have to pre -- literary value you walk on this trip yes it's very laughable yeah. We're the product made Australia and it -- party slate. To actually party shake in this state is a product. That -- company it. And so they're all uniform sizes valley using wooden shingles that come and offer to different. Witness to those guarantees that you're staggering -- joint -- you're getting good project yes that's installation you know -- line up. It's -- forces. Now my question is if you haven't finished the frame for the porch back here which obviously they've gotta -- why do an honest roofing now -- trying to beat the rain this is actually very good day. So we that we got a perfect weather today -- you have a lot of rain lately right there we have in our goal is to dry Eddie and now we have this new porch addition going on me and they have to. Stay back up the pilot plywood -- all right is going to be abused it."
