The one picture with the nail too high, looks to be shot too deep and right next to a seam really disturbed me.
That is a leak right there sooner or later and it will fail before the material does.
" IF"that nailing is consistent through out the roof,
Along with too small of a stagger through out the roof
It just doesnt work.
Amazingly i have seen sloppy too short of staggers survive because of good asphalt saturated felt.
And upon that revelation it looks to me like they installed ice and water shield over the whole roof.
And it might be its saving grace
So Maybe this roof will be ok…
14 rolls is the exact amount of rolls i would order also. Plus bring any left over partial rolls i already had from the last roof.
