" Hi Keith how are -- Bob great now tell me a little bit about the admit the shingle that we're using here these are eastern white cedar shingles that the world has actually grown in Maine. And it's manufactured in Quebec what are the different types of finishes that you can get okay we have a bleaching oil finish which is that we're using here exactly. And then we also have a solid latex acrylic stains. -- what the -- the -- and all the other fancy colors are still a big difference is do you want to see the grain of the wood still coming through or do you want an opaque finish either in the grey or the tan or some of these -- down here that's correct -- give it a nice silvery grey tone in about three years being -- decorative shapes like this to exactly. Kevin have you. Made yourself a story pole here yes. The first thing we do is we want to make sure that everything lands. Even at the top of the headers and at the bottom of the windows so in other words that you want the shingle bottom to sit on top of I header on a door or window or the shingle course to come right underneath the skills window is that what we don't end up with -- any small pieces or cut corners which can leak. This is story pole we set up where the trying to achieve five inches of the weather. We'll go from five's. And then mathematically we start dropping each one quarter of an inch so they're four and three quarters. So that it lands perfect at the top of the door OK so there's a lot of arithmetic involved yes and what about your first course how -- how do you go with the first course this first course is set an inch below all the plywood. And the plywood is set. Right on the pressure treated itself only originally framed the house all right we're hanging down an inch below it so that way there is no water can penetrate and go up underneath OK Andy you've got a chalk line in place there what's that for. While we get ready to snap our line we've done our first course and doubled up on the next one okay we're gonna snap the line we're gonna take the the straight edge off moving up. And get ready to do go -- course okay. So will the straight edge I mean this the chalk line be used for each and every course yes and also it that gives us a little bit of guidance so that we don't end up. Shouldn't the just. Staples too low and with a straight edge then continues to move along with the job yes. Yeah. Now Kevin what kind of fasteners are using -- basically we use in the seven sixteenths. By Internet kulana stainless steel wide crown staple it is stainless steel yes and the winter crown does that make a difference in terms of the shingles are spreading. -- it grabs it a lot better and that way it won't. The other skinny ones that they have will split the shingle and so we try to go as wide as we can and I noticed it when you're setting them up you butt them all together pretty much you don't leave much space in between them both vehicular united dried product and they're sealed already have been so we don't want -- leave a little bit of space just a little just a little bit alarmed -- A white cedar shingle sidewall. Up in New England here always think you're gonna get minimum fifteen or twenty years out of it is that right correct it's twenty to thirty years without doing things. At all and so when you've treated it with some -- bleaching oil. Does that increase the life expectancy yes it does then you can actually add more bleaching oil to -- as time goes on and add even longer."
