Hi folks,
My brick ranch has a normal shingled roof and the edge of the roof is curling up.. The plywood under-layment has basically pulled the nails out of the last rafter at the edge of the house.

It just rained really hard and I don't see any water stains or wet spots when I look inside.. Almost looks to me like they didn't use nails that were long enough to nail the plywood down. The roof is about 10 or 12 years old.

How do I fix this?

I was thinking of using some decking screws with large washers to screw it back down right through the shingles and then tar over the screws.. Opinions?

Thanks,

If it was mine I'd be stripping those shingles and paper, then removing any of the effected sheating and inspecting for cracked or broken rafters.
Even if you renailed that sheathing by now it's developed a curl that's not coming out with just a few new nails.

I had one that was doing that, in the dead of winter and wind blowing strong.
I got up there with some 8' 1X4 "s and lag screws.

Screwed it down for the rest of the winter, then in late spring had to rebuild it from the bare rafters out.

Seems that the builder put down fiberboard insulation first, then ply sheeting, paper and shingles.

They failed to use long enough nails to get through the fiberboard.

So the roofing was just laying on the rafters and held by friction.

Anyway an inspection is warranted, and possibly a rebuild of that area.

Rebuild from rafters out.

While the roof is open, I would consider adding some high wind or hurricane ties to it.

Since you know it's weak on this end, I'd inspect the other end and consider hurricane ties for it as well.

When you guys say "rebuild it from the rafters out".. You mean an entire new roof???

An inspection? By my eye's or a city inspector? Not sure what you mean.

Fiberboard? There is no fiberboard so much as I am aware.. Its just plywood nailed to rafters, then tar paper, then shingles on top of that.

Your eyes to inspect.
Then if you are not comfortable roofing, get a pro team out to rebuild it,

Which is tear off the shingles and sheathing, there, and as far as necessary to start replacing it with new flat sheeting, and paper, and shingles.

The fiberboard was on my roof as an insulation wrap, I did not mean that you had any.

Thank you so much for your advice. I roofed my own 12 x 15 chicken coop and did a really nice job on it.. But I think this is more than I want to take on as I'm inexperienced in repairs of such type. Heck, I just learned how to install a wood stove stack a couple years ago.. It wasn't hard at all and I did a really nice job on it.. But I'm slow as I do everything meticulously and am afraid if I tear off part of my home's roof, it would probably rain on me..

Thanks again for the advice.. very much appreciated.
