This low slope roof area was leaking. They originally had installed shingles in it. After it began to leak the home owners had hired someone to repair it (Not a Roofing Company). They installed architectural shingles down the edge by the wall and cap shingles over the existing ones on the hip area – needless to say it didn’t fix anything , it still leaked. So we tore it all up and replaced the bad decking , put down a new modified two ply system and new shingles. After a heavy rain that evening the homeowners watched for any sign of water leak and were very happy to report ” We have no more leaks. ” Another leak – repaired.
