    Hi everyone.

    My house is about 5 years old. On my lower roof, I noticed that there is a nail that is not fully hammered into the flashing. Should I just hammer it down? Or put some caulking on it? Is it OK to just leave it as it is?

    In general, is it a good idea to caulk the nails on the flashing on the roof?

    Thanks a lot!

    Paul

    Pull the nail out and put a new one in straight so it sit flush to the flashing. Then put a dab of caulk on the top to seal it. A nail won't make a water tight seal against metal flashing. Do NOT use silicone caulk, use a rubber base or a caulk like Geocel, NP1 or Dow makes some great caulks. Go to your local roofing supply store and get a quility caulk there. Silicone sets up to hard and doesn't allow for flexibility. And don't over drive it so you compress the flashing.

    Thanks a lot Oldognewtrick!

    Will the old nail hole cause any problems?

    I'm not sure what's underneath the shingles...

    Thanks!

    Yes, the old hole will be a problem. Take the end of the caulk tube and squirt some into the old hole. Then put a small dab on top and smooth it off with a wet finger. A little goes a long way.

    That nail never should have been there in the fist place.

    The flashing is totally incorrect. Flashing should never be done like that, but the toothpaste is out of the tube at this point.
