This is from a 40 year single family today.
Exposed nails in attic.
Something caught my attention in the attic.
Make sure the shingle has the proper number of nails in it also.
No more nails in the head.
Just make sure that you don t damage the shingles lifting them up.
Desperately enough in fact to consider making the major step of pulling down ceiling drywall to expose joists above.
Removing and replacing all of the shingles is not a very viable option because it s so time consuming.
Smaller nail holes will be permanently fixed by this method standard roofing nails would be either 3 8 inch or 1 2 inch making a hole.
Stately attractive and open.
Remove nail lift shingle and apply a small dab where nail penetrated shingle then push the overlapping shingle down and your done.
Unless you live in your attic the protruding nail heads shouldn t be a problem.
Tear off or not it is a lousy job in my opinion.
As you can see in pic 2 they drove screws through at rafter intersections only.
Fill small nail holes with silicone caulk or roof cement.
What should you do about exposed nail heads.
There are no exposed nail tips in coming through the roof decking in pic1.
That should not only protect you but insulate the attic against the hot and cold.
I would recommend doing this on a sunny day and after exposed to sun for a few hours.

In the worst case it will lead to actual leaks in your attic and this in turn can lead to moist insulation mold problems and other water damage.
A 10 length of each costs only 4 76.
The exposed beam ceiling look is one that many owners of conventional flat ceilings desperately want.
If you use your attic for storage and need protection buy an insulating foam and have it sprayed against the walls.
The shingles are no longer shingles so i m recommending a tear off.
