Our roof is about 10 years old now.
It is beginning to form large black areas that appear to be something similar to the steel corroding under reducing conditions, or a residual from the original finish degrading.
I'm certain that it is not mold, mildew or other similar type growths.
It is also forming minor rust areas along the lower edges.
We are looking into refinishing the roof's surface.
The problem I'm running into is finding a coating for the metal roof that is suitable for a potable water catchment system.
Nothing that HD or Lowes carries is obviously suitable, or is obviously unsuitable.
In looking around, I am drawn to GAF's TOPCOAT Membrane WOB, but cannot find a source for it in Hawai'i.
Anyone know of a local source for this product or others suitable for this use?
