Using rolled metal valley under shingles is a thing of the past.  Over time roofing over metal valleys causes pre-mature failure of the shingles due to excess heat transfer from the metal to the shingles.  Valley Seal is a nailable SBS product that seals around the nails to produce a water tight valley system, without the heat transfer.  Economical performance that will perform over the life of the shingles.
