Water seal on a 32 roof?

[DavidG]

Your top material appears to be a replacement of the original.

so where is it lifted (at the seam in the tack strip)....doet that look like it just needs a couple new nails?

[DavidG]

Nails per se likely won't solve the problem, which is likely caused by a lack of an effective sealer. You could apply some sealer first and then try tacking down the affected area and it might work. Likely, however, is that the existing tacks lost their adhesion due to the deterioration of either the tack or the underlying wood. Small screws (#2 or 3) would likely be a better bet than tacks.

From the looks of your tack strip picture it looks like a complete strip down and rebuild to get it right.

Now that I know it is not the original roof, I will tear it all out (carefully)and replace it with a Lebaron Bonney kit.
