[Bryant16e]

Nails that stick out past the bottom of the plywood aren't a problem per se.

The construction in these pictures looks as if it's well beyond "a problem."

Jim please elaborate.....

Eric:

Do you really want some help or are you just fibbing us?

[Bryant16e]

Really I wany you guys input.........

[randynavarro]

OK then. . .

1) Overspanned / undersize floor framing

2) Untreated wood buried in the dirt - it'll rot pretty fast

3) Regarding your original question; yes, its poor framing. In fact, I think its worse than poor framing.

4) The structure doesn't appear to be bearing on anything other than dirt or gravel.

In addition to the water damage and rot that's obvious in the picture, I seen wood that's in contact with the soil. That's a termite attractor.

I see inadequate clearances. Could you get everywhere in this crawlspace or did you have to stop because there were places you couldn't fit?

I see all sorts of improvised framing and plywood spans that are too great.

I see undersized joists and joists that lack proper support.

I can't see, but I know it's there: inadequate footings, inadequate wiring and inadequate plumbing.

Frankly, it looks like a complete mess.

Ok, well that make a lot more sense.

So. Starting from the beginning, the nails are *required* to come through the sheathing. Read the instructions on a bundle of roofing shingles.

Next, it looks like the rafters are awfully far apart. What was their OC distance?

Near the center of each picture, there are four pieces of wood. Two have their end grain facing the camera, and two have their long grain facing the camera. The end grain pieces are probably beams or girders. What do they rest on? I don't know what the long grain pieces are. Do you know what they were doing?

Are those 2x4 rafters? How far do they span? Are they sagging?

How much ventilation is there?

What caused the leak?

The rafters are actually trusses, and the 24" spacing is fine.

[Bryant16e]

There is a hole in sheathing that caused the leak, 2x4 rafters used no sagging. Not sure of of 4 pieces of wood could not get any closer the zoom of the camera got me in that close. It was at soffit vents im 6-2" it was a really tight a human pretzel, thanks for your patience and feed back I recommended the owner contact a cert. contractor to evaluate.

That's funny! I actually laughed when this was clarified. That explains the pink stuff in the photos!

What Jim said.

[hausdok]

Yeah,

I'm looking at that photo and reading Randy's remarks and going, "Jeez, Randy, come on, that looks like cells with some blown-in FG in an attic. Then Jim did it too and I'm going, "What the hell," and wiping off my my glasses going, "No, that's definitely a top chord. Look at the press-plate gusset between the top and bottom chords."

You two had me going there for a minute.

ONE TEAM - ONE FIGHT!!!

I started it! I started it! I had just gotten done viewing his other post that was in the crawl space and assumed this was another shot.

My bad. Crazy. Now that I look at the photo, of course it looks like an attic silly boy!

You crazy Northerners.

Is there is a problem where the nail come through the sheathing?

Assuming we are looking at the underside of a roof deck covered by asphalt shingles, and that the sheathing is less than 3/4 inches thick (most plywood or OSB sheathing is), then the nails are required to penetrate through the sheathing (per IRC 905.2.5). For sheathing that is more than 3/4 inches thick, the fasteners must penetrate a minimum of 3/4 inch into the sheathing.

In the bottom photo, to the right of the truss top chord, it looks like the sheathing is growing a beard.

Nah,

That's just where the guy manning the blower hose allowed the cells to hit the underside of the roof. It won't hurt anything. In fact, the borate in the cells will probably protect that portion of decking.

OT - OF!!!
