I live in South Florida, and as you are probably aware, Hurricane Wilme did a number on my roof. We just bought the house 2 months ago, with the knowledge that the roof was ending its useful life (it is 18 yrs old), and that we would have to replace it relatively soon. (By the way, it was 3 tab asphalt shingles, and the roof is approx 3000 sq ft, with no valleys))

Wilma took 60% of the shingles and scattered them over our neighborhood. We were told that it would take 12 weeks for someone to even come out and look at it, much less fix it, and that may take 6 months. I am pretty handy, so I decided to do it my self. I stripped the roof down to the plywood, and it seemed in good shape (it is 15/32), so I left it alone. I then did the drip edge and 30# felt paper. Now that I have done one part of the roof (with 40yr dimensional shingles), I am noticing that in some areas the shingles arent laying completely flat, or there are areas that are depressed. At first, I thought they would lie down after a few days in the heat, but they aren't. I also thought that, due to the felt paper not being completely flat (it was a bit "bumby" in places) that that was the reason....but I was told that is not the cause either. I think that it may be due to the plywood being lower in some areas between the trusses......does this sound correct?

If so, exactly how do I brace the plywood back up into place? Please be specific in your description of the process, as I do not have much experience in these matters.

Thank you in advance for your help!!!

if this is caused by plywood delaminating or sagging, the only solution is to remove tjhe plywood and replace it, but you surely would have noticed that before laying the tqarpaper and whole tearing off the old roofing.

I believe it more likely that wrinkles in the tarpaper carelessly laid without stretching it arte the culprit, or that the shingles are wrinkled as you lay them and you are nailing the wrinkle into the pattern permanently.

Excellence is its own reward!
