A limb caught my crank up antenna and snatched it off the roof. The original coax is damaged somewhere inside the roof and is not accessible. And I cannot pull a new cable inside the roof.
So I plan to run a new coax from a new antenna, run 20 ft down the center line of the roof and adhere with blobs of lap sealant every 12-18 inches. Will drill hole in roof and drop new coax into an electrical closet.
Any tips? Expansion/contraction? Leave slightly off roof between lap seal blobs to allow for water drainage? Has anyone done this before? Comments?
Thanks

Seems like we replied to this a few weeks back. Take it you did not want to pull inside. Did you check just below the roof line where the antenna is installed. As stated almost always a connector there so only a few feet to add.
Not a lot to pull on the roof. Point A to B, glue, tape and drill a new hole and seal.
This might help you. Ideal

Correct, I had a post a few weeks back. Wasn't a matter of not wanting too, I can't. The Winnebago motor home has solid styrofoam in the roof. There is no air space. They cut out channels for the wiring harness and air vents prior to being laminated together. This makes it impossible to pull any wiring thru after lamination.
I did check just below the roof line at the antenna mount. I did not find any coax connection. I also checked with Winn Tech support. They said Winn runs a continuous line from the antenna head, down the crank up lift arm, into the roof, down the 20 ft length of roof to the electrical closet. So there is no connection under the antenna mount. The closest connection is in the electrical closet. Thanks though....

Just because they did not originally have a connector does not mean you could not create a splice and add a connector just below the roof line.
If the roof is only filled with styrofoam you should be able to create a channel for the coax through the styro foam.
Maybe I'm missing something But running a new line across the roof does not seem like the most efficient way to reconnect the antenna.

Some we can some we can't. You try a splice by chance.

I have used the AC duct in the ceiling to run cable through if reasonably close and accessible.

On topic
I ran coax from the back of MH to front for same reason. I found that using dicor by its self did not work. For me the coax would not stay flat long enough for the dicor to harden. I ended up getting coax cable clips to hold it down while the dicor dried. I can not remember if the nails that came with the clips were long enough or not. I was not a fan of putting more holes in the roof, however by using way to much dicor I felt safe.
Good Luck

You do want a secure connection at both ends of the cable ( at least). They make wire ties with an opening for a screw. Use one at each end and maybe one in the middle. This will keep the coax taught and then additional days of Dicor every 2 feet or so will keep it secure to the roof ( no gap) for years to come. I have almost 40 feet of coax on the roof now. Has been there for years.

I assume there is a piece of coax going to the antenna below the roof line. Cut that coax and put a connector on it. Then get a new piece of short coax and run it from the existing piece to the antenna.
If there is styrofoam blocking the bath use a long drill bit or piece of pipe to create a hole in the styrofoam.
I don't see it as being that complicated.
You don't need a home run all the way pack to the inlet connection.
