Removing Satellite Dish from New Roof

[jaw22w]

I had a new roof put on about a year ago. There is an internet satellite dish mounted on it. They recently ran fiber internet down my road. and obviously I had them hook me up to fiber internet. Now I need to remove the dish. It is lagged to the roof.
What is the best way to patch the holes left by the removed lag screws? I was thinking to just fill the holes with silicone.
What's the best way, short of patching in new shingles?

Either leave it be, cut it down to the mount and leave it be, or remove the lags and use a roof sealant to caulk the holes.

It always blows my mind when I see them bolt a satellite right through the singles.

I used silicone when a nail backed out and made a hole in my shingles... No issues that I know of. I bought a pack of shingles to replace it but Ive not got a round-tu-it.

I had a dish that had been installed on new roof. Shingle roof, 2003 installation.

A few years later, I took down the dish and left the mount brackets. In my case the brackets were only going to be seen by someone wandering around my yard. It wasn't an aesthetic issue. I figured if they don't leak, why open up the holes.

Years later, I picked up a weather station with a pole mounted sending unit. The dish brackets are now used as tripod mounts for the weather station.

The simple answer is that it's fine to leave them if you don't mind the look.

LOL! Just the thought of getting rid of that ugly assed dish off the front of my house alone was enough to get me to switch to the fiber internet! I also have a TV dish that is biting the dust at the same time. I don't want to leave the brackets. I think roof sealant might be better than silicone in the lag holes.

Henry makes a polyurethane roof sealant.

I've used it for a few things, roof and not, it seems to stick very well...

On second thought, it might be PL brand. I'll have to see if I have any left.

I did exactly what OP is planning though. I had some old brackets (braces for electric mast) that were lagged down. Zipped the lags out, pumped the hope full and smeared a dab on the surface of the shingle.

I've been in the attic, there are nice sealant stalactites hanging from each hole and no water signs. From the ground I can barely see them, and I know where to look.

I think I would pump the holes full of roofing cement from a caulk gun.

Then carefully lift the upper shingle up, run a bead of sealant around the holes and slip in a piece of flashing to cover the holes, and lower the shingle down onto a dab of sealant at each corner. Then touchup the entrance wound on the top shingle.

I just did this last month. I used silicone from a squeaze tube and wish I'd planned better. If I had used a caulk gun I could better force the silicone down into the holes. I like the idea of the roof sealant better than silicone also. Dang couldn't you have posted this thread 2 months ago?

I don't know if this is the best answer or not, but it does agree with what I've done in the past and will do again. A stiff paint scrapper works well to lift the shingle without major damage. Just aim well and tap gently, don't jab and hammer.

I removed two satellite dishes from my roof two years ago. I pumped the holes full of Henry's roofing goop (blue tube, 7 year lifespan), put some in between the shingles, and then smeared a layer on top of the shingle over the hole. No leaks or issues so far! I like the idea @larry4406 has about lifting the shingle and then putting a ring around it with the sealant and then a piece of flashing.

Henry’s is your friend for this.

If you can pry up the shingle to access the holes, squirt in whatever you have and squish the shingle back down. You want to see caulk come up out of the hole. You can flatten what comes up. Grab some shingle rocks from the gutter and sprinkle on top. The caulk in between forms a flat surface that acts like a flashing.

a year old roof? I would get a bundle of matching shingles, remove the bracket & lags & replace the compromised shingles

This.

When we got our new roof, I squirreled away a whole pack of matching shingles just in case I ever had to do something like this. May not be a perfect match after a few years, but a hell of a lot better than the alternative.

I had this done a few years ago. I don't go up on roofs anymore, especially the 12:12 I have, so I had a guy come by. He replaced a shingle or two and used roofing sealant to fill the holes. The roof is about 20 years old so the new shingles don't perfectly match, but it looks better than the dish

 

[jpaw]

I just pulled them off and put the lags back in with sealer on the threads and over the top. A few grains from the gutter and good to go.

Remove the dish
put the lag screws back in with a washer and some goop/sealer under the washer

I like the idea of getting "gravel" from the gutters and sprinkling it on the filler.

Just take the dish off, put a little thermoplastic in the holes, put the screw back in. I’m guessing the dish was installed in the gable end or the eave? Do you have any extra shingles around? You could take a flat bar carefully pry up on the shingle above it, pull out as much of the shingle with the holes as you can, make sure you get it out at least as high enough that when you put the shingle back down that you other up, it covers the seem from the new piece you put in. When your pounding the nails back in, you know what, it’s 10 times harder to explain how to replace this shingle than to actually do it, if you decide to go that route I can explain it to you. But if your not, I won’t bother,

I wouldn't use silicone. I would use a proper roof sealant that any hardware store or big box store should have. People seem to think that silicone is the answer to everything. I've done the shingle replacement thing, but it can be a decent amount of work to get it done right.

Dicor self leveling lap sealant also works really well. I had some laying around from camper roof seal touchups and used when I installed our OTA antenna to the roof. I did this 10 years ago and it still looks like new, and no leaks.

Right after I had my stone coated metal shingle roof put on. The Direct TV installer wanted to put the mount on my roof even though I had requested him not to. Luckily for him I was there. Made him place it on a pole in the back yard.
