Will this work on a copper roof that has turned black over 20 years?

I haven't tried this on copper, only steel and chrome. It's worked very well on those materials and don't see why it wouldn't work on copper, though doing a roof seems like a huge undertaking.

I have had great results on copper ornnaments but I have not used it on a roof,maybe you can try it on a small section.

Yes sir, but wear protection as that much exposure could be bad for you. Thats a LOT of copper oxides, and I feel it would be almost certianly poisonous, even w/ a power polishing rig (like the power drill adapters for mag wheels etc.)

Update------Buy the 550 version, it's cheaper by the ounce and comes in a 72 ounce container--really big!!!It will probably do the job, but that job will take many,many hours of wiping, polishing----and a boatload of dollars!!!

I believe it would. It must be solid copper though as Wenol minimizes scratches by taking the top surface away. It's a great product. Wear gloves. Janie Harrison

I'm not sure if it will work on anything. I tried it on a slate roof and it ran off like water. This stuff is terrible. Don't waste your money.

Hello, we have a metal roof and it worked for less than two months. But I don't believe it had anything to do with the roof. We have an old fashion roof antenna that works very well.

I think it would work well on any bare metal, as long as you wipe it clean with some rubbing alcohol before coating it with the paint. The alcohol will remove any wax or greese that may be on the copper, or any surface for that matter. Be sure to spray 3 to 4 very thin coats within 10 minutes of each. Make the last coat the heaviest without running the paint.

if you have the black stains or streaks on your roof this product will not work, you need to call a non pressure roof cleaner, and cleaning a roof can be done above 40 degrees if your using the right product , straight chlorine works the best if you have a way to apply it and don't rinse

HI- A good copper cleaner will do. Like Twinkle, etc. Apply the paste to outside only

It worked on a 20 yr. old garage door opener in a house I'd just bought...might be worth a try!

I have only used it on very bright, well cleaned brass, and it worked very well. Just make sure the copper is very clean and that it has not been previously coated with anything.

It should work just fine, as long as any rust hasn't caused pitting in the metal. But, for discoloration, it should work great.

It should, i used it to repair the spoiler on the back of our suburban...it does come in black or cream color as well.

Yes, we have, and it works very nicely. It does leave some dark marks on the roof liner, and you will have to check the tension on the vertical supports from time to time. We are very happy with ours, and I think you will be too.

Not sure on some that old. But it works well and I think it is worth the try. Mine was on cement so asphalt could be a problem.

It does a great job on brass and bronze. Copper is the main component of bronze and is in brass too. It should work on copper.

Yes, I have cut copper roof flashing with it. In order for it to cut metal you only use the thick dies. It won't' work on the sizzlits. Use the Vintaj embossing folders made for embossing metal for the best results.

Hi Freddie , No if your home is very old , and using knob and tube wiring , I think it works best on homes with NM cabling where the hot, netural, and ground wires are in one cable. Trade people refer to it as Romex but its just called non metallic or NM or NMB which means it can be use in areas with higher ambient temperatures. Hope I Helped Ray

Well, it certainly should. Sunshine, above freezing temperatures and no rain after application as per application instructions sure would insure it's effectiveness.It will kill the mold, mildew & moss growth and then rains should wash away the residual. GIVE IT 3-4 months to work. It will slowly "go away".If the moss is heavy it may then require another application to finish the job. Your roof should return to "like new".
