In Campaign IL visiting with DW BFF of over 50 years for a few days. Rain in forecast so climbed on roof to check after the last month of 90 deg temps. A small section of roof to front cap trim has lifted or buckled to cause a 4" long gap about 1/8" high in the joint compound. Filled it with flexible sealant for now to prevent water egress. Area has been "topped up" with the famous self levelling sealant that is now 4 layers deep in this area during my warranty period at the dealer. Most of this stuff is starting to crack where ever it has been applied.
How do I remove all this stuff and start sealing the front and back cap from scratch? What aftermarket sealant should I use that is compatible with the Alpha roof material?

Brad,
Sealant is difficult to remove. One would never get it all off. You can use a plastic putty knife but you have to be careful you don't puncture roof membrane. You can use dicor sealant. Some will say no to dicor but Alpha has told m it is ok to use. Hope this helps, good luck.

If you want to remove ALL the old/cracked stuff , use a plastic scraper and proceed very carefully . . Then I would use Eternabond to make the repair and forget about it.. When done proper , there is nothing close... You could also just go over the old stuff with a strip of eternabond , but that's your call . .

I forgot about the eternabond. I agree this is a great product. I carry some of it in my unit all of the time.
