Explore the process of assessing framing and sheathing in building construction, specifically focusing on the roof area. This article provides practical tips on examining the details of structural elements like stud walls, parapets, and exterior sheathing in the context of a building project.
Key Insights
- The importance of checking the details of a structure, such as the two-by-six stud wall for framing and the use of three-quarter inch plywood for exterior sheathing, is highlighted, emphasizing that these details should be consistent with the rest of the building.
- The article underscores the need to confirm the height of specific structures, like parapets, during the takeoff process, using an example of a parapet with a top at 24 feet and a roof deck at 21 feet 10 inches, resulting in a two-foot parapet.
- Creating a detailed takeoff for exterior elements such as the parapet and properly labeling these details, including the height and type of material used, is essential for accuracy in planning and construction.

All right, so now that we have completed our framing and our sheathing on level one, both the interior and the exterior, let's go ahead and move up to the roof area and see if there is any additional interior or exterior framing that we need to complete. So jumping over to page 13 here, we can see this flat roof around the guest room, and we mentioned earlier that there is a parapet there, and we were doing the roofing takeoff. So let's go ahead and look at this detail on D7.4. And let's go ahead and collapse our markup bar, get that out of the way.
So scrolling down here, we've got detail number six on D7.4. Looking at this detail, we see a two by six stud wall for framing. So that's exactly the same as the rest of the exterior framing, so that's great. And we also see a three quarter inch plywood, which is the exterior sheathing.
And that looks to be the same as the exterior sheathing around the rest of the building. So good news, we're able to use the same takeoffs that we've already created so far. And let's go ahead and zoom back out of this.
And one thing we want to do also is just confirm the height of the parapet that we want to carry in our takeoff. So jumping over to A5.1 here, going up to the west elevation, we can see that the top of the parapet is at 24 foot, and the top of our plate or our roof deck or slab is going to be at 21 foot 10 inches. Let's make an assumption here that the top of parapet is going to have a two inch parapet cap on it.
We'll say 23.10 is going to be where our top of wall framing is going to go. And we'll say top of plate here still at 21.10. So that's going to give us a two foot parapet that we are carrying. So jumping over to sheet 13, let's go ahead and do our takeoff of this parapet here.

Let's just grab ourselves a poly length and make a new item out of this. Since we do not have a tool chest for our exterior framing, I don't believe. And we're just going to go ahead and call this our two by six, I believe we had it called typical two by six exterior stud wall.
Yep, so we'll type out two by six exterior stud wall. And let's just make, sorry about that. Exterior stud wall.
And let's just make a note here that it's at the parapet, just so we can designate that for ourself. And since it is at the parapet, we will just say two foot high to let ourselves know. And we can go ahead and take the spec section here and change it back to 06 wood framing.
And let's just go ahead and make this that same red color. That we've been using for some of our other exterior framing items. Great, so we've got this takeoff created.
Let's go ahead and do this takeoff here. We are just going to ring our outside here with this parapet. We've got our framing, it's going to be two foot high there.
And also to just add to it, we can hit our units drop down up top and we can give this a two foot height as well. So then that will give us a real wall area here of 176 square foot. And what we're going to do is we're going to go ahead and copy this takeoff.
And we are just going to paste it in place. And we're going to go ahead and get our drywall from that as well. So let's just change this color back to that darker red.
Let's just go ahead and change the name of this to our exterior sheathing, which we should have in a drop down. We're going to be assuming drywall both sides. In this case, we're going to say plywood.
All right, so we've got our framing for the parapet. We've got our sheathing for the parapet. And that is going to be the rest of our framing and our sheathing on the vertical surfaces.
All right, that looks great. Let's continue in the next video.
