/diy/ - Do It Yourself

You're looking at sheathing under a roof. You can see how badly it has curled. on the top of the frame, you can see how the builder used staples instead of cap nails to attach the sheathing. It looks like someone bent a nail at one point trying to fix it.

As you can tell in the photo, the felt is torn and the shingles are lifted enough to let day light in.

Is there any way I can fix this without damaging the shingles above?

>I thought about using a toggle bolt, but it would protrude.

>I thought about cutting it out with an oscillating saw, but I am worried about cutting to deep. I would then replace the sheathing from inside by bracing between the rafters with a stud, but then the shingles would not be nailed down.

>I thought about putting a piece of lumber underneath it, slathering the mating surface with construction adhesive, and leaving a weight on the top side over night. This doesn't seem like it would last.
