The church where I'm the new pastor has a flat roof connecting two older buildings - the flat section was constructed in the 1930s when flat roofs were all the rage.
The roof was replaced 17 years ago with a vulcanized rubber roof, and a pitch of about 2% was put on it for rain and snow run-off. The roof material is in good shape (thank the Big Guy!) even though the roofing company closed a few years ago (the owner retired and dissolved the business instead of selling it).
Here's the question: near where the drain hole is for run-off at one end of the roof there is a low spot, and rain run-off forms a pool there about 12 feet (3+ meters) in diameter and a depth of about 2 inches (5cm).
Short of ripping up that section of the roof and redoing the underlayment to eliminate the low spot, does anyone have suggestions on how to get rid of the water on a regular basis? Anyone know what effect that water and sunlight is going to have on the rubber over time?
