" -Well, we're gonna get started with Tony Stein, our framing inspector and Tony I believe you like to start your frame inspection on the 2nd floor, right?"
" -That is correct"
" -And why would that be?"
" -We mainly wanna come in and view the span on the ceiling joist"
" -To ensure they're adequate for limited storage space. "
" -So you have to go each room, check out the dimensions, like this is a 14-foot bedroom, what kind of a ceiling joist are your looking for here?"
" -2 x 16 in. on the center is substantial."
" -Okay, And if it were a little bit bigger, then you'd have to go a larger sized lumber."
" -That is correct. We have the spans in the code, the tables in the code and if it exceeds those spans, then he would have to size up to a 2 x 10 or double up each individual"
" -or sister them"
" -correct"
" -That doesn't happen too often, though"
" -Not at all."
" -Yeah, let's look at the roof in this section over here so you can tell us what you'd be looking for here."
" -Mainly what we have here is we have a roof-ceiling combo"
" -It's a cathedral ceiling; it's that what you mean?"
" -Correct, cathedral ceiling, in the code book it would be called a roof-ceiling combo, that's the best word I got."
" -That's the terminology"
" -Yes"
" -So what he has here is an engineered ridge beam which alleviates the outward pressure on the exterior walls, these are collar ties that come across and connect the rafters at each side"
" -And he has a large enough rafter to allow for a minimum R-19 insulation in that rafter space with Generally what we look for is a 1-inch air space between the roof deck and the top of the insulation to carry ventilation from the soffit vent to the ridge vent"
" -Yeah, and the ridge pole, that big piece of engineered wood though, that's 1 of the key things"
" -Very key"
" -in having good a structure, good. Alright so we pass there, What about actually tying down that roof, here we are in the land of hurricanes And we've gone to a lot of trouble to put clips everywhere, are there other things that you look for?"
" -When you're in a historical setting, as we are here, they are bumping the roof line"
" -Oh,"
" -And we would call of a plate extension on top of the wall plates"
" -Right, cause the actual wall plate is this but we've got an extension up to here and the roof rafters all sit on top of the extension. The reason this is done so that we've got extra height above the windows for a cornice line to get across"
" -That is correct"
" -So what are you looking for there?"
" -One of the main details here is things that we often find is we have a break with the orange stranboard here and often no wall treating here so if they failed to apply that all the way to the top, what we would need to do is see the top plates which straps to the studs forefoot on center, because the sheeting, the skin of the building, whether it's OSD or plywood is what helps to tie that roof down"
" -That is correct"
" -And if it hasn't been applied all the way to the top, then it's not gonna hold the roof."
" -That is correct"
" -Alright, so these are some of the key things here. What about as we go down the stairs and go towards the 1st floor? This corner right here, it's carrying some of the load of the roof system down through here all the way to basically the footing so the foundation"
" -Right,"
" -Generally, you have an isolated pier or what you might have is a larger beam from pier to pier."
" -Okay and here obviously throughout the house, we've got engineered wood products, glue laminated beam, LVLs and all of that. Hey, here's another question, though, what about when you got a masonry mass like this?"
" -The masonry should be independent of the frame which he has here, as you can see, approximately 2-inch air space."
" -That is in case you have a settling in the footing, it does not pull the framing with it."
" -a lot of times you may see a house that is no longer standing, but the engineers go there"
" -That's an important consideration. Well let's take a look at the underside of the house."
" -Okay"
" -And at this point, we're verifying that the girder is carrying the load and not the joist and it transfers to these isolated piers down to the footing of the building."
" -you figure out why they call it a cross-space. Alright, so what about on the outside of the house Tony, where you've got porches and big roofs like this, what do you look for?"
" -What we're looking for, of course the rafter connection to the house, carrying down to the beams and later on we'll come back to verify that the straps are tied to the header down to the band board and carried to the pier."
" -Yeah, there's still a couple of places where they have to tie it down"
" -Correct"
