Does anyone have any tricks for removing a silver asphalt roof coating? I was able to wet sand it off of the drip caps but not looking forward to sanding the entire roof. I haven't found any evidence of leaking so I can't figure out why it was even applied.
Can I paint over it?

Sorry I cant answer your question but I am also curious about this stuff. I think it is called silver seal, the PO of my camper coated the roof of mine with it, but I dont know much about it, that's something I have to deal with down the road as well.

You could try Goof Off. That stuff can dissolve roofing tar. If it can do that it might be able to do the same for the silver stuff.
I wouldn't paint over it.

I've replaced roof metal because of silver slop-like icing on a rotten cake. Sometimes you can get it to peel.

It seemed to release a little easier when we put the trailer in the sun and scraped it hot.

I tried Goo Gone which I think is the same stuff as Goof Off. Didn't even smear the silver stuff.
I was able to peel off the heavy stuff with a putty knife, (and lots of scratches to the skin). Since replacing the roof isn't in my budget, I guess I'll just have to sand it off. It came off of the drip caps fairly easily with wet sanding but what a mess.

I don't know. I think Goof Off is a lot stronger than Goo Gone. It is worth a shot. A heat gun might help. Got one of those?

Okay, I'll try the Goof Off next. I don't have a heat gun but I may try dragging out into the sunlight today and see if heat helps. Thanks!

Looks like I'm going to have to use paint stripper. I tested a small patch and the silver stuff comes off easily with it. I was hoping to go a little greener on this project but so far nothing else has worked.

I actually did not try the Goof Off. I went to Home Depot and read the bottle and it seemed to be designed for removal of petroleum based products. I'd have been willing to give it a try but when I calculated the amount of it I'd need, it would have been pretty costly. Also, I'd made the mistake of going online and had seen a product called "Liquid Hammer", which supposedly removes concrete from metal, but they didn't carry it at Home Depot. I found out later that the company isn't in business. In any case, I went home empty handed, so I decided to try paint stripper. The paint stripper worked well, I decided to go that route. I'm told that I will need to treat the aluminum with something now to get the paint to stick again. That will probably be my next post/question to the forum  . If you try the goof off, please let me know the results. So far, I've only tested a small patch on my trailer so if you get good results I may change my technique. |

Removing a 14” roof vent.
Vent was sealed with black roofing tar. Tar is rock hard.
Having good luck with a heat gun and putty knife. Going is slow, directing heat at tar and knife blade lifts tar smoothly.
Not wanting to scratch the roof, I am leaving a thin film of tar. Film cleans off with lacquer thinner.

Silver stuff is called Cool Seal.Of the the things that have been outlawed i wish this stuff would have made the cut,and while im on the subject there are other things that shouldn't on campers like SILICONE & GORILLA GLUE.I'm sure these items have a use but i dont think they were made for rvs.

Update: I tried the Goof Off. With a wire brush I was able to make some scratches but hardly anything came off. Once it dried I tried sanding it but it became solid again. I'm with you, neilandromona, the stuff should be outlawed!

What brand paint stripper did you use? My roof has the silver slop looking stuff and it's almost like bondo underneath that. Then in places there is the black tar stuff. I have all three vents to replace and the seams have the junk on them too!

I used a brand called Klean Strip. I haven't done the whole thing yet, just some testing. BTW, I had my trailer in the shop a few weeks ago and asked them what they recommended. They tried everything and ended up with acetone. Its cheap and did a better job than the stripper. Once I run out of my stripper I'll probably switch over to the acetone.

Paint thinner works pretty well on tar. Gasoline works better but is too spendy these days, not to mention explosive...

I just spent the evening removing the tar on my trailer that was plastered on around the old vent. I started with some paint remover and let it sit. After that I dabbed some lacquer thinner on with steel wool and wiped it off. It is now all clean and ready to go for the new vent. |
