The metal roof with a baked enamel finish on our mountain cabin has been worn away over approx 15 years by the granular Calif snow. Now it looks galvanized instead of brown!
Is there any way to recoat it? I’m afraid that just trying to just repaint won’t last… Suggestions?

Switch from 80grit snow to finer - somethihng in the range of 600 grit will buff it up nicely.
but there are polyurethene opaints formulated for roofs. possible to find epoxy paints also. I would visit a good paint store.
That's "Paint store" not big box store. Go where pros go and you may find professional advice dfrom a retailer who knows his product line.

I get a magazine called Rural Builder. Add a .com and have at it. Lottsa metal roof and products, I believe they may have a forum. Roof coatings are a proprietary product. At least good ones are.
I 'think' I also get one called Metal Roofing. Try a Goggle on that.
Where's Greencu?

I've not dealt with that type roof much, but I've been curious to hear how long the finish will last. The finishes are generally polyester or kynar and are proprietary. I'll be curious as well to see what resolutions come into play here.
I invented cheese grit snow.
We generally spec Sherwin Williams Pro-Cryl Primer B66N310 with two coats of S.W. Acrylic DTM Enamel B55Z600 for painting exterior galvanized metal but we go to a Kynar 500 field paint for exterior metal applications that will see above average wear. It seems like there's a 15 year warranty on Kynar 500 if I'm not mistaken.
The bright red aluminum columns we field painted with Kynar a couple of years ago have taken some pretty major sun and still look great. We'll see how they look in 15 years.
Greetings Jim, Welcome to Breaktime.
Good quality paint can work wonders rolling on a nice protective coat or two.
There are also rubberized compounds that are available in 5 gal pails. Quality debated by the amount of particles per which of course will cost more.
An internet search of roof coatings should bring up ample info on brands.
I had good success with a brand named "TopGuard' which provided a number of different formulas for various applications.
