How To Tar Paper A Shingle Roof Valley Section

This is how I paper my vallies.  I swear it is the fastest way out there.  Take a close look at how I paper the 30# in the center of the valley.  Then I run a roll of 15# felt paper diagonally down the valley, close enough in that I can tuck my metal w-valley under.  Then I just run my 15# in the field on to the diagonal and cut it straight.  Very waterproof, but saves you reaching for those long diagonal cuts.  Try it once, you'll like it.
