How to Best Run New Coax on Roof ??

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
