There is at least a 4' difference in the cap, no way they used a chalk line, probably anywhere on the roof. There are of nails visible all over the roof and not caulked, there should be no nails left un caulked anywhere, nails are popping up around windows. There are even high trusses 2". Siding gaps un caulked, siding cut 2 1/2 inches short in hidden areas. There is a constant leak in the garage.
