Abstract
ALL ROOFS EVENTUALLY LEAK-IT IS JUST A MATTER OF WHEN AND WHERE. NEVERTHELESS. THE HOPE IS THAT NEW ROOFING SYSTEMS DO NOT LEAK RIGHT FROM THE START. IT IS CRITICAL TO VERIFY THE WATERTIGHTNESS OF ROOFING, ESPECIALLY IF IT IS TO BE COVERED WITH BALLAST OR A VEGETATED ROOF ASSEMBLY. THIS VERIFICATIQN IS A FIELD QUALITYCONTROL MEASURE BEYOND THE SCOPE OF A ROOFING MANUFACTURER'S VISUAL INSPECTIONS FOR ISSUANCE OF A WARRANTY. FOR EXISTING BUILDINGS BEING CONSIDERED FOR A REROOFING PROGRAM, CONDUCTING A ROOF SURVEY TO DETERMINE THE LOCATION AND EXTENT OF WET SUBSTRATES IS ESSENTIAL TO MAKING FISCALLY RESPONSIBLE DECISIONS RELATED TO THE PROGRAM'S EXTENT.
