just wanted to pass along the problems that are accuring do to the solid stickem strip on alot of
the spotted strip is in spots for a reason, which is to allow water to escape out the bottom when it enters at the sides.
so if your layin these shingles with the solid strip i would recomend not warrantyin them.
i have run into several new roofs that are traping
water inbetween shingles and rusting out the nails.
i cant beleave some manufacters have forgotten about this very important spotted sealant strip.
