Condo development had a problem with some rusting chase tops, and stains all over the aluminum trim. Roofer suggests that he can encapsualte rusted tops within a rubber roof with aluminum trim.
Upon examination the rusted tops are still exposed by 1/4 to 1/2 an inch, and I think these will continue to rust and cause problems.
If the edging were longer, and covered the rusting metal, do you think the rusting will stop? Do you think it would have been safer to remove the top and install a new top made of metal? Remove the existing top, and apply a rubber roof?

Rubber roof on cap ???....uhhhh no. Have a new cap fabricated out of pre-finished metal (any metal shop will do this..you measure/provide sketch), twist off flue cap and remove storm collar and slip new cap over flue and fasten. You can also re-wrap the facia/top band in metal or prime and paint the existing.
We replace these often and it is not costly. I wouldn't recommend capping/patching over the old.

The rubber repair doesn't really address the damage that has already been done - just covers it up. Plus the continuing rust under the repair will likely lead to streaking and staining on the cladding.
Here is a company that does nothing but chimney caps for just this type of situation... I haven't had the chance to use them yet but I am considering them for use on several EIFS condo repair jobs that we are consulting on. Seems a lot easier than trying to customize something in the field.

Thanks for the reply- In another life 25 years ago, I installed pre-fab metal fireplaces, and installed tops like that, but galvanized. I was looking for tops like that, but could not find a source.
