roof sealant

[Squaredancer]

Hadn't been on the roof for a while, thus noticed that the sealant used around all the vents, skylite etc. (a black looking affair) has developed rather large cracks. Question becomes how to fix all this ?! To start I need a name for this product, then do I just fill in the cracks or do I remove all and recaulk ?

I just did all the seams, vents, and drain stacks with etrnabond tape, no need to remove the old cauk, just clean the caulk and put the tape on, stuff works great, never need to redo or reseal the roof, I bought the tape on the net from Best Materials, a 50' roll was 50.00, plus the shipping...more expensive than caul but you never need to fool with it again...I covered everything on the roof that had any caulk, well worth the money and time..hope thais helps

When I install my MaxAir fan in the bedroom a local RV dealer turned me on to this stuff. http://www.proguardcoatings.com/roof-intro.htm

I used it along the seams of the entire roof and around all the vents. When I installed the MaxAir I did remove all the old caulking from the old ventbut for everything else I went right over the top. My shower dome was leaking until I covered the cracks around it with this. Since it starts out as a liquid it self levels and fills in any cracks. So far I'mhappy with the way it turned out. Mix the 2 chemicals together in a bucket and use a 2" paint brush to put it on.

Dicore is the caulk. It is self leveling and works well. Just clean the od stuff and put the new caulk over it.
