Not to be a smart a$$-Why not call a local Dtv Dealer to do you install?
It doesn't look like you're going to have have a lot of room to work with in a few years. At least from that angle.
Unless there is an invisible redwood across the street. I see nothing that would prevent your dish for going anywhere on your roof. Could even go on a pole in the front yard if you wanted. Dishpointer is saying that the tree will need to be 129ft tall to be a problem. At most, it might be in the 80-100ft range. You've got LOTS of room.
I would never mount a dish on the roof. He could have put it high up on the side of the house next to the chimney. The holes in the roof over your living space will eventually leak.
I would have gone with the back corner of the roof so it wouldn't have been seen from the front of the house,Just my two cents worth.
Installing a dish on your new roof will NOT void the manufacturers warranty.
Shingle warranties exclusively cover their materials and their performance.
Installation of anything on the roof other than shingles is not covered, even with the highest level of warranty coverage (requires additional warranty fee) which is over and above the standard warranty.
This includes the underlayment (felt, Ice and Water) , flashing, counter flashing that are not from the manufacturer. Roof top HVAC units, pipes, braces, gutters, Satellite dishes, Radio/TV devices.
That's why all shingle warranties are labeled as "Limited" Warranties.
There ya go!
IF you are a Directv employee and they say not to install masts over living spaces then that is your instruction. In some areas Directv is actually doing the installations as an owner / operator. They are the employer and can tell employees exactly what to do.
In the past, installation contractors and then the Directv Home Service Providers (also contractors) were issued specifications and paid for completed installations. Directv didn't care where the dish went because they were insulated from the damage claims.
AND there is the trigonometry of the situation. IF the roof pitch is less than or equal to the elevation angle of the dish the signal will not be blocked. In such cases there is no benefit to putting a dish way the hell up in the air where it is hard to service and looks like a dish on a roof etc. So why not be prudent and also make things easier by mounting the dish low on the roof? The cables can be led to the ground block and prewired lines can be connected easily. IF there is a leak there is no real damage.
In this case the dish is already way the hell up there and there will be expenses (bet ya) moving it. There will be holes to patch and new holes to make.
If that install meets DirecTV guidelines they need to change their guidelines. There is no doubt the roof will leak eventually. And there is absolutely no reason it needs to be there.
If a dish absolutely, positively has to go on the roof, it should be over the soffit area so when it leaks (not if) it doesn't cause too much damage.
The problem with your LOS is the tree(s) next door, not across the street.
The good news is that you've got a 3LNB, otherwise you'd be hosed.
The sat you opted to map, 99° is the easiest to acquire for your situation. The 101° and 103°, clockwise 2° and 4°, are not only closer, azimuth (AZ) to the tree, but at a progressively lower elevation (EL).
*My low precision LOS tool*
From behind the dish, looking up at the sky, extend your right arm/hand/fingers, hold your thumb/index/middle fingers together and stretch your ring and pinky fingers apart from each other and the rest. Slightly rotate your hand clockwise, so that your thumb is a couple of inches higher than your pinky (sloped down 30° or so left-to-right). Your digits represent 99°, 101°, 103°, 110° and 119° respectively.
The LOS from behind the dish cascades down (sort of like walking down steps) for each successive sat (west of the Mississippi the opposite is true). 101° and 103° are not significantly worse than 99°, but they are worse, and you are right up to the limits with the tree. If you do relocate your dish, try to move it SE as far as possible.
Done correctly, a roof mounted dish will not cause a leak, ever....where the issue could arise is if you take the dish down....
In nearly 14 years I've had 4 different dishes on my roof, both on the old one and now the newer one. Directly over my living room. Not one leak in all that time.
I'm a commercial roofer so I'm picky about stuff on my roof. I insisted on only one thing. No silicone on my roof. Each time the installation was quite good, and I didn't have to "clean up" the installation afterward.
Done correctly it WILL NOT LEAK!
The "not over a living area" rule is nonsense. Many houses around here have a very small if any soffit/overhang at all. In fact, mine has about a 3 inch soffit.
I think in what you read DirecTV worded it improperly. It should be more a long the lines of "If you can choose to put it above the soffit or above living space, choose the soffit.
DirecTV would have you do almost anything to get a new customer in.
There ya go again....introducing facts and logic into this stuff!
I once refused to revisit a one story rancher with a huge roof overhang; mas grande soffit! The complaint was a roof that didn't leak before that" .........with the Directv fixed up that thing on the roof." I knew I had not walked on the roof and had not punctured the almost new shingle job; lags into the truss end supporting the facia works every time.
To shorten this...the ladies' son, myself and a rep from the installation company formed in the basement while we had the little old lady flush her toilet.....the plan was to get my insurance carrier to fix her pipes because the roof leak had damaged the plumbing.
Dishes installed properly never leak. Those installed less than perfectly may leak some time. But that will not stop folks from picking up the phone and seeing how far their dime will take them.
My HD Dish was put on my roof for the same reason as the OP. Too many trees in the way. I didn't mind it being on the roof. But snow buildup last year meant I had to temporally change to my SD dish. For me I'd have to gone 150FT from my house to get away from the trees to put on the ground.
You had a Chimney you should have had the installer use a chimney strap.....
Here's another type
I talked to DTV. A tech is coming out today to find an alternate location. The chimney mount is another option to consider. I think my wife got over the initial shock so I may just leave it where it is for now and see what happens this winter with snow/ice.
not if the installer used bishop tape between the base and the roof.
your not allowed to put a slimline dish on a chimney.
if your standing by your dish while taking that picture then the tree across the street is not in the way.
