DO METAL ROOFS INTERFERE WITH CELLULAR PHONE RECEPTION?
Typically not! It’s pretty unlikely that getting a metal roof on your home will drastically change your cell phone signal.
Metal Roofs and Cell Phones
Metal roofs are becoming more increasingly popular with homeowners, because they have so many benefits. One common question that might be asked is this: “Does a new metal roof affect the cell phone reception in my home?”
Cell phones have become a necessary part of life for the majority of the human population, in developed countries, anyway. Bad connections, poor voice quality, dropped calls, texts and emails that won’t go through – not to mention trying to share videos with large file sizes, are extremely frustrating and not something you want to be dealing with every time you’re at home. Without good service, your smartphone is practically useless.
However, people tend to forget that they regularly use their cell phones under metal roofs without even noticing it. Many of the restaurants you eat at, the malls you shop at, and other businesses you regularly visit have metal roofs, and you don’t lose cell reception while inside. Your home environment, with a metal roof, should be no different.
What Causes a Poor Cell Phone Signal?
There are various factors that can affect the strength of a cell signal in your home, such as where your home is located, if it’s in a valley, its distance from a utility tower, weather conditions, and which cell service carrier you use.
Bad cell phone reception generally falls into two categories:
- Localized poor coverage, where you can get better signal by moving to another room or going outside. This kind of bad reception is due to building materials or some other local destructive interference, and can often be fixed.
- Geographical poor coverage, where the whole area has a poor signal. This kind of bad reception is because you’re just too far away from a tower, and in this case, you’ll have cell phone issues with or without a metal roof.
With such strong networks today, if you’re near a city or in a developed suburban area, the cause of a bad cell signal is far more likely to be localized rather than geographical. There are two main culprits for localized poor coverage:
1) Interference from the buildings or landscape around your home. If there’s something blocking a direct line of sight to the closest cellular tower – trees, buildings, hills for example, the signal will need to bounce off something before it can be received by the tower. In this case, you’ll typically experience a signal that fluctuates up and down.
2) The construction materials used in your home. Common building materials like brick, metal, wood, and energy saving window coatings can impede signal coming in, causing weak signal or dead spots in your home. You’ll discover this when you have perfect signal outside your home and lose signal once you’re inside.
A metal roof is just one of many building materials that may weaken cell phone reception. Generally, if you do have poor cell phone service in your home, it will be due to the cumulative effect of the materials used. No one material will be exclusively to blame.
So, metal roofs don’t actually interrupt cell phone reception. If you have consistently good cell phone signal in all areas in your home, a metal roof shouldn’t make any noticeable difference. Unfortunately, if you currently have weak or spotty cell phone signal inside your home, it’s possible that a metal roof could contribute to the overall service weakness.
But if you currently have poor cell phone reception, and you really want the beauty of a metal roof, do not worry. There are ways to work around this slight inconvenience.
