Calking a roof

[imjustdave]

Doing my annual review of the roof and I'm starting to see cracks in the calking. Figure it might be time to too fix it before winter.

So do I just fill in the cracks? Cover overt all of it with more stuff basically in tombing it. Or remove it all and start fresh?

Advise? Tips tricks greatly appreciated.

just clean and then recover....or better yet clean and put down eternabond

I entombed mine with new after cleaning it. It was a messy job but it seemed to work just fine. After a few days I looked to see how it self leveled and cured and it looks decent enough. And, it looks well sealed so it will be effective.

Scraping and replacing appears that it would have required 10 or more tubes of sealant. Covering over took me two tubes of sealant. The sealant was expensive so I'm glad I didn't have to pay 5x more money to do the job.

I'll second the eternabond solution, did mine a year ago and love it.

I 3rd using Eternabond with the thought of removing the old caulk first. If its already cracking that means it's breaking down. Why leave something there that's going to have to be replaced at some point anyway? Eternabond, when done correctly, is for all practical purposes a permanent fix. There is a great tutorial on their web site on how to do it.
