Many people are hesitant to get a metal roof because they fear it will worsen their cell phone reception. Other related worries are that the metal roof will also impede homeowners’ satellite signals and WiFi connections. So, is it true that metal roofs can have a negative effect on cell phone reception?

Metal roofs can worsen existing problems with cell phone reception, but there are many contributors to poor reception. The surrounding landscape, the building’s material type and thickness, and poor localized coverage can all negatively affect it. The best way to boost cell reception in a building with a metal roof is to use a signal booster.

This article will cover whether metal roofs cause poor cell phone reception, WiFi connection, and satellite reception. It’ll also discuss the causes of poor cell reception and how to boost it.

Do Metal Roofs Cause Poor Cell Phone Reception?

According to experts, there’s no evidence that metal roofs disrupt cell phone signals more than other roof materials. Consider all of the different buildings that have metal roofs: offices, warehouses, restaurants, malls, and many more. Generally, people do not experience poor cell phone reception every time they’re in a building with a metal roof.

Reasons For Poor Cell Phone Reception

So, if the roof isn’t the culprit, what could be the reason you’re experiencing poor cell phone reception? There are several possible causes.


First up is the landscape. If the building is located in a valley or surrounded by tall buildings, this can affect cell service. This is because these types of landscapes cut off the line of sight between the building and the closest cell tower.

Material Type And Thickness

Another possibility is that the materials the building is built from are impeding cell phone reception. Construction materials such as metal, cement, wood, and brick can cause problems with cell signals. This is especially true if those materials are particularly thick.

In general, it’s not a single item or material that causes poor cell phone reception. It’s the combination of several of these materials.

Poor Localized Coverage

As you may already know, cell towers conduct the communication needed for cell phones to work properly. Therefore, your coverage will likely suffer if your carrier doesn’t have enough cell towers or if they’re too far apart.

Does A Metal Roof Interfere With Cell Service?

The idea that metal roofs interfere with cell service is a very common misconception. However, no credible research exists to back up this claim. Still, metal roofs can be responsible for worsening existing service problems.

For instance, if a utility tower is close to a building with a metal roof, you may experience service interruptions. This means your cell phone’s radio frequency can be suspended. But the problem here isn’t with the metal roof; it’s with the tower itself.

Do Metal Roofs Block WiFi?

Metal roofs are unlikely to have a noticeable effect on your WiFi signal. However, they can contribute to a combination of factors that can negatively impact your connection.

Surrounding buildings, metal objects near the modem or router, and poor localized coverage can all play a part. Your ISP’s (Internet Service Provider) service, the devices and software you use, and the building’s construction materials can also contribute.

When you experience a poor WiFi connection, it’s often the result of many different factors.

Do Metal Roofs Interfere With Satellite Reception?

Metal roofs don’t interfere with satellite reception any more than other types of roofs. It’s important to note that the satellite dish should not be directly mounted to the roof unless that’s the only option. The better choice is to mount the dish to an eave or wall.

This is because drilling holes in a metal roof is almost certain to cause leaks. This can lead to rust, oxidation, and other issues.

In addition, be sure to mount the satellite so that the roof does not block the signal. Any type of roof will interfere with satellite reception if you’re attempting to aim the dish through it. The dish should always have a clear view of the sky and should not be blocked by the roof.

How Can I Boost My Cell Phone Signal With A Metal Roof?

The most common solution to boost your cell phone signal is to install a signal booster or repeater system. This system consists of an inside antenna, an outside antenna, and a signal amplifier, with a cable connecting these parts.

How it works is that the outside antenna picks up the tower’s signal and sends it to the amplifier. Then, the amplifier boosts the signal, and the inside antenna broadcasts it to the surrounding area. This provides a strong connection that is then picked up by your phone.

What Are The Disadvantages Of Metal Roofs?

Just like all roof types, metal roofs come with advantages and disadvantages. On the positive end, metal roofs can last 40 to 70 years and are extremely durable and safe. They’re also energy-efficient and environmentally friendly.


On the flip side, metal roofs come with drawbacks as well. For example, they can be as much as two to three times more expensive than other roofing materials. Although they have a long lifespan, the initial cost of installation is high.


Metal roofs can also be very noisy during rainfall and hailstorms. One way to make them less noisy is to add extra attic insulation. However, this is obviously an added expense.

Issues With Fasteners

When a metal roof is assembled as large panels, it’s designed to expand and contract as outside temperatures fluctuate. But the exposed and concealed fasteners in the metal roof have varying lifespans. Screws and neoprene washers can degrade and even become dislodged over time, depending on the climate.


If the roof isn’t installed or repaired properly, water can accumulate and cause significant damage. In addition, if low-grade metals are used, they may be less durable because of their thinner gauge. Also, in some climates, some metal roofs can rust and dent more easily in inclement weather.
