Roof tiles

[chiefred]

Is there a simple method for drilling through roof tiles and then sealing the area between the hole and the cable? Is there a substance I can buy off the shelf at Home Depot or Ace Hardware?

I would not drill through roof shingles !!

like gene said I would be running down the roof and in through a wall

If I had to go through roof tiles I would have the customer get a roofer involved just to fover my rear

I hope you never go into the Home Improvement business

When needing to go through the roof we use a piece of conduit and a roof jack. Depending on the roofing material it can be quite a challenge. I would not recommend drilling a hole and caulking around it, that really messes up the roof design. I personally don't have a problem with it, I've done enough construction and roofing that I'm pretty comfortable installing a roof jack. If it is a ceramic tile roof I'd probably not tackle it, too brittle and easy to mess up quite a bit.

If you haven't done this before, call a roofer and have a roof jack and piece of conduit installed if you must go through the roof.

Good Luck!

It is only my opinion, based on my experience and education...I am always willing to learn, educate me!

If the only way I can get coax is across the roof ---and since it is not recommended to go through tar shingles is there something I can use to secure the cable to the shingles-- also I remember someone saying something about a "jackson roof mix" or something for filling.

If you need to penetrate the roof let a roofer do it for you. You could lay out the cable on the roof and then secure it with 'roofing tar' or construction adhesive.

I would just lay it out and not seure it

Secure it with the wrong substance and if there where roof problems it could come back on you

Coax over the roof?

We don't do it anymore, but that used to be a common thing....

Things to remember:

Check the UV rating on the cable you're dealing with. Some PVC coax cables will NOT fair well to direct sunlight, they'll develop a chalky texture... and eventually water will penetrate into the dieletric, which can cause problems with egress and ingress, furthermore, reflections... etc.

If you can ONLY get it there over the roof, what's wrong with some conduit? That's what I would do...

Because of the structure and the customer not wanting anything hanging on or under the front eaves---as well and the 3 levels--it would be way too expensive for conduit---I can't run it along the sidewalk and wall--the only way I can do this is a portion has to go over the roof about 45 feet on the roof and the rest under the eave and then into the family room--if I go the opposite direction I will use about 300-450 feet of coax and it would take me about 1 full day to get it under the eaves and secured so it doesnt hang--thus more money than its worth.
I was thinking of using the "U" nails so they just break through the shingle to secure into the wood and not through. Then sealing them with some tar substance. I know there is a compound for patching that is acceptable.

 

[AvayaNovice]

No no, I meant conduit over the roof. Why not do that? Safeguard your cable, and that way... you can secure it using roofing nails, and tar them while you're at it, or have a roofer show you the correct way to secure the pipe straps.

I am sure this isn't leagal, but I have drilled into the side of a vent pipe and gone in there and then pulled it back out in the attic area and resealed using butyl rubber based sealer. This was a flat roof situation and the customer actually helped me come up with doing that.
