  1. Dear Allen Sensel,
    Along the same lines,, I have a flat roof that has some standing water and have put on emulsified asphalt and seem to stop it but it keeps coming back after a few months. It’s a torch down bithumen roof.
    Thx.

  2. Thanks for the information! The building that my business rents has a flat roof, so there’s a lot of ponding that happens after storms. We haven’t had any leaks after working in this building for a couple of years, but I’m still worried that it may become a problem for us later. It’s good to know that there are some flat roofs that are made with drainage in case ponding occurs. I should still check to see if our roof is equipped with proper drainage so that any ponding in the future won’t become an issue for us.

  3. A recent development in combating ponding water is the use of liquid silicone. Since it is not an organic product it is impervious to ponding water and sun. Think of it like a roller applied pond liner.

    If you look on line there are a number of manufacturers that offer silicone. It is a good solution to safely resolve ponding issues and the product last for a very, very long time.
