Hello, first posting to Usenet so hope all goes well...
I just got up the nerve to inspect my attic (unfinished, just beams
and stuff) ... I noticed these light, tan-colored splotches of color
on the rafters that LOOK kind of like random paintbrush strokes,
dispersed among many of the rafters. Some splotches are big, some
small. Some rafters don't have them at all.
I've prodded the area with a screwdriver and the wood seems sturdy
enough. When I rub one of the spots with a finger it feels kid of
powdery. It's a foreign (to the wood) substance of some kind, but
There is also -- noticeable if you stare at them for a moment -- a
faint "sparkle" to the rafters in general, as if someone coated them
with, well, faint sparkles. (And, no, I don't take drugs ;)
The roof has a fan cut into it, and all seems dry, no signs of water
damage. When I shut off all the lights I don't detect any pinhole
light getting in or anything. Roof looks okay from the outside (no bad
shingles, etc.) The house was built in 1958.
Any idea what these spots might represent? I'm pretty much a complete
novice, as you can tell. :) Should I worry or be happy or just .. be?
Thanks for any help/ideas anyone could offer.
