Why your valley could be leaking.

This is a roof valley that Stones River Roofing was able to repair in Middle Tennessee.  It had a history of leaking and several roofers had attempted repairs without success.  This roof is within a few years of being replaced, so instead of rebuilding that section like it should have been done originally, we secured the valley shingles with roofing cement and "dog-eared" the corners.  It has been tested with a few heavy rains and the leak has been fixed.
