Hi,

I think I understand what the rubber roofing is. It is a hugh piece of plastic film that is glued to the roof. Thanks for the term.

I don't think this is what I need right now.
I need to stop the leak at the pool of water near the tiny drain hole in the back of my house.

I am thinking to cover the section where the pool of water is with one of these Henry Wet Patch Roof Cement thing. But again, I don't know what I am doing since I don't know nothing about fixing anything. I think this Henry thing is very difficult to use becasue it is very thick. It will be back-breaking to use a putty knife to put this thing all cover this section.

They also have something called Elastromeric Coating. I don't know what it is but from their instructional video, you just "paint" it on top of the roof with a paint bush. It seems very easy.

Would you mind that I ask what is this Elastromeric Coating thingie? Will it help me to fix the leak of mine?

I am confused becasue all the stuffs they sell all say that they will stop/fix leaking roof. And when I read the instruction on the can, they all say that I need to fix the leak first before applying any of their products.
