I own a mobile home that was manufactured in 1990. This unit is 14 ft wide
and 80 feet long. The metal roof is not the older "hump style" but instead
is pitched like a regular house but only in metal. I am now noticing some
spots that have surface rust starting and I am wondering if anyone has ever
had a situation like this and maybe had their roof treated for the rust and
then some final coating or paint? Since the roof is pitched the older type
of mobile roof coating would just start to drip down the sides of the home
if the Sun really heated the roof metal up. Any product suggestions? This
home is in Indiana.
Thanks in advance for any help or suggestions.

If you want to maintain the metal roof, then the source of rust must be
treated to stop its progression before anything further is done. There are
some products on the market that will chemically convert rust to a
substance that prohibits futher rusting. IIRC, it changs the color to
black, so you might need to repaint either the entire roof or at least
those areas that were treated, if you can find a paint that matches your
OTOH, we have a double-wide with a pitched roof of fiberglass shingles. If
it were my home, I would probably invest in shingles to cover the metal
The method you choose to correct the problem is almost directly related to
how much money you want to spend. BTW, the roof coatings that are used on
many mobiles are not inexpensive, even if you could use it on your roof.
Product is called "EXTEND". IIRC, it sprays on clear, but turns rust areas
black. Sand first. Makes the rust a NON-rust substance right away. You
then could top-coat with finish of your choice.
I may be wrong but I don't think the Kool-Seal product properly applied will
do that. Once it dries it is set. As long as you don't slop it on so heavy
that it runs before it dries you should be fine. You will pay more for the
brand name but the product really is that much better!
Whatever you choose to paint it with I suggest you keep your weight on the
"rafters" as you move about or use a scrap piece of plywood to distribute
your weight between 2 of them.
