White substance on attic rafters

[Joshua L. Frederick]

Any idea on what this stuff would be? Causes? etc. etc. I have seen white mold-like substances in attics before, but this didn't appear to be.

Thanks!

Joshua,

Very difficult to tell from photo's (need close up for better idea) but looking at the pattern of the "stuff", I suspect it is from when the home was built. Could be mud, concrete residue from using the lumber as forms, or just poor/sloppy job site conditions.

Any more info? Did you touch the "stuff"? What did it feel like? Did you give it the level II taste test? Age of home? Close-up pictures?

Joshua,

I would note it as " Job site construction related debris, possibly paint, drywall mud, concrete etc. prior to installation."

This is on some boards and not on others boards attached.

Unless, there has been major roof damage in the past and this crappy lumber was brought in to do repairs.

Either way it does not look like a concern.

I agree...it's probably either construction debris or whatever skin disease Michael Jackson had....either way, not of much concern.

I agree. Loos like form wood. Quite common in older homes like that.
