DIYbanter - View Single Post - Rubber Roof Leaks when snow and water builds up

In article .com,

I have a flat rubber roof that leaks very badly when it snows and then
rains. It happened twice this year during two storms between Feb and
March. The weight of the snow and rain somehow must pull the rubber
away from where it should cover the roof from the outside elements.
When it rains hard it never leaks.

I'm guessing the leak is always there, but when it just rains, the water
ponds lower than the leak and runs away.

When the snow builds up, it elevates the backed-up water so it reaches
the leak. Could even be going over the top of the rubber where it runs
up on the penetrations.
