please tell me if these drops are normalDrops hanging in attic with nails?
The drops of water on the nail tips are probably due to condensation--the nails sticking thru' the boards will be colder than the board and the water droplet forming on it is in essence 'Dew'.Don't worry-- it's not leaking, if you're concerned, you could try increasing the amount/size of vents.Drops hanging in attic with nails?
It's condensation. You may not have enough circulation in your attic. Make sure your eve vents are open as well as your roof vents or ridge caps. If they are all open, you may have to install more vents on your roof.
We had same problem last year. Normally I wouldn't go up there in January, but we did have water dripping through ceiling in a mild spell. What I immediately did was pull insulation away from the soffits (after ten years, it had spread itself evenly everywhere) and this blocks ventillation to your overhangs (common cause of ice dams). BUT, the real culprit is our house is 1920's, has no vapor barrier, and in the kitchen, we have no exhaust hood over stove. The roof over the kitchen was like a winter wonderland--inside! So, if this sounds familiar do things like: don't steam up a room, remove ceiling light fixtures and squirt foam insulation in all openings to the attic, and if your ceiling looks cracked coat it twice with good latex to provide some barrier. If you ever re-do a ceiling, put in some vapor barrier. Oh yeah, that reminds me, I still have to get an exhaust hood.


ALSO, if you have an exhaust hood or dryer vented into the attic, disconnect it now--some people do such things and its bad, bad, bad.


All advice about vents is good, but doubtful you're gonna do that right now.
That is normal. Condensation. Happens in winter. Nothing to worry about.
The moisture in the attic is condensing on the roof and collects at the end of the nails. Did you put in roof vents at the ridge when you put in the new roof? You may be able to install a vent or two between the joists. They are less than $30 each at home depot. You'll need to cut through the roof which can be a real job unless you have a reciprocating saw. A skill saw can do it but it may ruin the blade. Since you can access the attic, drive a long nail trough the roof from the inside centered between the joists so you can locate the vents between them.
