Check out the new plastic felt replacements. Stuff is perfect for slow
roofers (DIY) as it tolerates months of exposure. Much better and
safer to walk around on, too. Seems to be the material choice around
here (central midwest). The only roofing I've seen with ordinary felt
in the last two years has been a prebuilt garage. Use plywood whenever
possible (holds nails better) and Grace watershield in all the right
places, valleys, etc. Locally, woven valleys are the norm for better
wind resistance, I suppose. Also, thick tab shingles have replaced all
the old skinny ones except on tract houses in the outer developments
being peddled to kids that don't know any better.
Have your shingle supplier deliver the bundles to the roof top to save
you time and grief. Your vertebrae will appreciate it.
