Unless you live in your attic the protruding nail heads shouldn t be a problem.
Exposed nails in attic.
Cut the tubing into pieces about 3 8 to 1 2 long depending on length of exposed nails in your attic then push a piece of tubing onto each nail point.
That should not only protect you but insulate the attic against the hot and cold.
The exposed beam ceiling look is one that many owners of conventional flat ceilings desperately want.
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.
As you can see in pic 2 they drove screws through at rafter intersections only.
I would recommend doing this on a sunny day and after exposed to sun for a few hours.
Make sure the shingle has the proper number of nails in it also.
Stately attractive and open.
Removing and replacing all of the shingles is not a very viable option because it s so time consuming.
Tear off or not it is a lousy job in my opinion.
Just make sure that you don t damage the shingles lifting them up.
However you can take care of exposed nail heads.
But that rarely happens.
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.
Remove nail lift shingle and apply a small dab where nail penetrated shingle then push the overlapping shingle down and your done.
A 10 length of each costs only 4 76.
The shingles are no longer shingles so i m recommending a tear off.
If you use your attic for storage and need protection buy an insulating foam and have it sprayed against the walls.
No more nails in the head.
Desperately enough in fact to consider making the major step of pulling down ceiling drywall to expose joists above.
This is from a 40 year single family today.
Something caught my attention in the attic.
Fill small nail holes with silicone caulk or roof cement.
