Top 3 Reasons Why You Should NOT mount a satellite dish on roofs
Drew Calloway

For years, Homeowners across the U.S. have been getting their satellite dishes mounted on their roofs without fully acknowledging the damages they have just signed off on. Although it is true that if properly installed, when you mount a satellite dish on roofs, it wont bring as many issues. After all, the higher it is the more signal strength from the satellite in our atmosphere and the more time you get to enjoy your evening news. Not exactly. The height of your satellite has as much to do with the signal strength as direction does. Due to the satellite in the atmospheres orbit, if you live in the norther hemisphere it is only logical that the dish faces south to keep a strong connection. We continue to damage our roofs due to the convenience of the height on our roofs when in reality we could be saving them.

Many People Mount a Satellite Dish On Roofs: Whats The Big Deal?

Here is the Top 3 Reasons why you should NOT to put them on your roof.

• Risks of a Bad Installment •

• Long Term Roof Damages •

• Warranty Void Risks •

1. Risks of a Bad installment

Many factors go into installing a satellite dish on a roof. The style and height of roof determine where the satellite dish goes on the roof. To properly install a mount on the roof, a rafter has to be located underneath the shingles. Then holes are drilled into your roof to secure it in place. Normally a rubber sheet will be installed with the screws to ensure that it stays and doesn't leak. Sometimes a sealant is put over it to ensure it doesn't leak also. The screws are not the only things making holes in your roof though. The wiring that connects the satellite to your home gets stapled down into your shingles making smaller holes in different shingles and cracking them. The cracks left behind risk expanding during the rain or snow and becoming a worse problem. 



A bad installment could go various different ways. No sealant could be used when installing the mount, the rubber sheet may be forgotten, the satellite dish could be put in without finding a good rafter to hook it onto, etc. In the end, the lack of any of these could mean excessive leaking, wood rot, shingles damage, and even damage to the satellite dish itself. A proper installation will cause superficial damages meanwhile a improper one will lead to very serious ones.

2. Long Term Roof Damages


After the install of the satellite dish on your roof, it becomes subject to the elements. Even if it does not leak or show damages right away, the possibility of it doing so later still arises. When the wind blows, it pushes against the dish, pushing and pulling it. The constant pressure on the dish and then in addition the state of your roof as it ages, can eventually lead to ugly damages. Any wiring left behind can ruin the rain run-off that allows the rain to roll right off your roof. The collection of water leads to water damages and leaks.

The cracks in the asphalt shingles will expand due to the elements, the 4-6 bolts holding down the dish could start to rust and make the dish unsteady and even damage the rubber sheet underneath, later leading to leaks through the rusting bolts and damaged sealant.  
In the long run, the costs of getting it professionally installed wont beat the costs of a necessary roof repair/replacement. 

3. Risks of Voiding Your Roof Warranty.

Whether you just got your roof done or you got it completed 5 years ago, you most likely have a warranty on your roof. Now depending on what kind of warranty you have, it may not matter as much but it is critical to know what your warranty covers. When installing your satellite dish on your roof you are accepting a variety of risks and approving of superficial damages on a specific portion of your roof. In the situation the person you hired to install the dish originally didn't install it properly and it caused a leak in the area it was installed, there is a great possibility your warranty can and/or will be voided. Or just not applicable. 

Most Roof Warranties will state that unless the damage was due to the elements or something it was advertised to protect against they will NOT cover it. Most of the time this covers the usual elements and roofers will repair your roof if it was due to something they did. But because the installment was done by a third party, they will most likely not repair it under warranty. Most Roofers will suggest not installing it on your roof before hand due to the possibility of voiding your warranty. 

How Should The Satellite Dish Mount Be Installed?

It is recommended that satellite dishes be mounted either on the side or on a pole of some sorts on the side of the household. The pole should be anchored down by cement and be able to hold up the dish enough to withstand windy weather and any other unexpected events caused by the elements. This pole should be close enough to the household to connect the wiring without a problem.

 On the other hand, mounting the satellite dish on the wall or fascia works too. Eave Mounting, which is the process of mounting the satellite dish off the roof and on the side, works well too. It does not provide damage to your roof and keeps it close enough to avoid any extra, unnecessary wiring. The process, like any, involves the same number of bolts that would go on the roof on the side of your house. Eave Mounting holds the advantage as it is much more reasonable, rain is less likely to get in and you avoid the costly risks roof satellite mounting causes.

If this hasn't convinced you enough, multiple service providers that mount their satellite dishes actually have began to install the dishes off the roof and use the pole method of some sorts. There are new regulations and due to the risk of the workers they have stopped installing them on specific roofs. Eventually the roof damages it causes will be the lead cause of Eave Mounting installments.
