TV renovation question

7 years ago

Hi all, not even sure this is the right spot and if not, please direct me to the right area. I had my TV hung on the wall over 2 years ago. Randomly, not every time but rain sometimes comes through where the hdmi cords were ran. My contractor went on the roof where the chimney is and put a bunch of silicone just in case. I went in the attic but it's all blown in insulation so I can't get all the way over to the other side is the house. It seems to come out where the brissels on this thing are in the picture. My contractor also said roof looks fine but flashing on chimney us old and that's where he silicone. Anyone have any ideas or who I should call?

    I would call a reliable and well known for doing top of the line work, roofing contractor. He should know just what to do to take care of the problem.

    It has to be coming from the roof though, unless you have AC unit in attic and it is leaking?

    We need to see pictures of where the cable enters the house.

  • 7 years ago

    @cat no ac currently installed in the house.


    @sammy it's just 2 hdmi cables and an ethernet cable for my TV. Literally 25 foot cables that are run next to it behind the wall where the media center is.

    Does the coax cable enter through the wall? Did the installer allow a drip loop where it enters the house?

    @david the coax cable comes through the wall about 25 feet away but no issues over there. However, it actually entering the house is no where close to where this is. It comes from downstsirs...a good 100 feet away.

    This is the whole back of it. The electrical outlet is on the other side and I've never had issues with anything coming out of that one. It's just the other one and honestly not every time it rains. It has to be a hard rain and windy and even then it doesn't always happen. I'd say in 2 years it's happened 7-8 times.

    Why would HDMI and Ethernet cables penetrate the outside of the house? I would think only the incoming coax cable should.

    @tox I don't have any that come through the house for this. I have the fios box on the other end of the house and that goes into where my panel is and then is all run inside so has nothing to do with this issue.

    Bathroom or laundry room located above the TV room?

  • 7 years ago

    Nope, just the attic which has all blown in insulation up there I tried to venture over to where the TV is to see if there was a leak but could only make it halfway and couldn't see anything. But if it's coming down the chimney (my contractor thinks it's the flashing on the chimney being old and needing to be replaced) then I wouldn't of been able to see it in the attic anyways.

    You cant see the flashing from the attic, but, you would be able to see where water ran down the chiminey, or dripped below it.

    Here's a few pics. First 2 are before the silicone my contractor used. He told me it definitely needs to be reflashed if it's still causing an issue and a roofer would need to do it.

    Took off the plate and bracket tonight because it came in a little today (can see the drip on the wall). I touched the insulation behind and it was dry. Touched all around and didn't feel anything. I contacted 3 roofers tonight to see if they can come figure it out.

    Had a roofer out Wednesday to check. He said it was the flashing they replaced it all and said when they took it off it was really wet under there. He said that should fix it. First big rain tonight since then. Also said I need a new roof next year.

    adding - I would have the chimney tuck pointed, then flashed. When roofing add ice/water membrane as well.

    So that explains water getting in to the attic... maybe. How did it get to HDMI wires to show up at the jack behind your TV?

  • 7 years ago

    @saltidawg they are saying it was between the cavity of the fireplace and the wall and because there was a hole in the wall added it gave it a place to escape. They said if you never caught it over the years it would add up and turn into mold and start to crumble the fireplace between the wall and you'd finally notice it but it'd be way more money to fix it. We'll see if it is actually fixed when it rains tonight.

    A little update as it has been raining for 15 hours straight now and heavy rain and windy too. Knock on wood, but no water has come in. I think the flashing might have solved the issue...hopefully!

  • 7 years ago

    Take back my previous post. I just checked and there was just water again. I mean the flashing needed to be done regardless because it was deteriorated, but I wonder if it is a chimney issue.

  • 7 years ago

    How does the top of your chimney look? Mine is mortared all over and there are cracks in it. Water can get down in between the bricks.


    Is your attic accessible? You could go up there when it's dripping and see if you find any wet spots on the underside of the roof, running down walls or rafters, or dripping onto insulation or the attic floor.

    @tox yes! Mine is the same way mortared at the top but cracking and looks like retaining water as the crack marks are wet. When the roofer was replacing the flashing the other day he took a pic and showed me and thought it was really weird. There was other parts of mortar that were doing the same in the brick in some spots. I think it's a chimney issue but the roofer is trying to sell me a roof of course.


    I can't make it over to where it's happening in the attic as its all blown in insulation and I have to way to walk over there. Plywood wasn't put down to create a path.

    > Plywood wasn't put down to create a path.

    So put some down now. You're not going to solve this until you figure out where the water is actually getting in.

  • 7 years ago

    I'm getting plywood up there. The mason wants to run a water test and said he'll charge me to throw plywood down but then it's there and I don't have to worry.
