If you have a satellite dish mounted on your roof, you should check it regularly to make sure the roof under the dish isn't leaking. You can look in your attic at the underside of the roof so you don't have to climb up on the roof and risk an injury.
Satellite dishes can leak, and you might not be able to tell it by looking from the ground like you could spot a missing shingle. Here's a look at why a satellite dish might cause a roof leak, signs of a leak under your dish, how the roof damage is repaired, and how to prevent problems in the future.
Why Satellite Dishes Start Leaking
The dishes are mounted to the roof with nails or screws that make holes in the deck and shingles. Where there are holes in your roof, there is always a risk of leaking. The nails might back out or rust and allow rain to leak through the hole. Also, the wind rattles the dish and causes movement that affects the shingles. This can cause shingles to crack and leak.
How To Spot A Roof Leak Under A Dish
A roof leak from a satellite dish is like any other leak, except the leak might be difficult to see on the surface since the dish is in the way. However, you might see rain dripping in the attic or see signs of water damage on the rafters or insulation. Your attic might smell musty. There could be mold in the attic or your house, and if the leak is bad enough, there could be water stains on your ceiling or walls.
How Roof Repairs Might Be Done
The repairs needed depend on what kind of damage has been done. If the problem is caught during a routine inspection, the roofer might seal the open holes to plug the leak. If shingles are cracked or damaged, they'll usually have to be replaced.
A leak that has gone on a long time may have ruined the plywood deck under the shingles. In that case, the roofer may need to make extensive repairs once the dish has been taken off and moved out of the way.
How To Prevent Future Leaks
If your dish has to be taken off for roof repairs to be done, consider moving the location of the dish. You might mount it on the eave or a pole. The dish company might charge a relocation fee to move the dish, but it's probably worth it to eliminate the threat of roof damage.
If you want to leave the dish on your roof, be sure to check it regularly for signs of leaking. You can have a roofer check it up close to make sure the seals around the screws haven't deteriorated and that the shingles are in good shape. If you can't prevent a leak, you want to catch it as early as possible so roof repairs can be done promptly.
