If your roof is only 3 years old, I assume that you have a warranty. Be very careful about using any caulk that is not expressly approved in the warranty. This also goes for installing other accessories, flashings, sealants, patches, or equipment. Otherwise the warranty will likely be voided even for other defects which seemingly have nothing to do with the use of the caulk. Contact the installer or manufacturer for approved caulks.

There is a caulk called lap sealant that is used for seams and around protrusions....I dont think homedepot carries it...******* does or the local roofing supply house that sells epdm roofing does.

good luck, if I can be of any more help my email is leeyohe322 at cs.com

the blocked out type is men@rds

Thanks...lap sealant (by Carlisle) is what I actually ended up going with. You were correct that HD does not carry it. I found some at a local roofing supply warehouse (they were also a good source for advice). Supposed to rain tomorrow, so I'll find out how good of a job I did. :)
