Does a Metal Roof Affect Cell Service?

Sep 22, 2025

Separating Fact from Fiction

If you’ve ever heard that metal roofs block cell phone signals, you’re not alone  it’s one of the most common myths in home improvement. Many Montana homeowners considering metal roofing ask the same question:
“Does a metal roof affect cell service?”

The truth: A properly installed metal roof has minimal impact on cell signal strength. In most cases, weak signal problems are caused by other factors  not the roof itself.

roofing services in lewistown and Great Falls, Montana, we’ve installed countless metal roofs for homes, businesses, and farms. Here’s what you need to know before making your decision.

Understanding How Cell Signals Work

Cell phone service depends on signals sent between your device and the nearest cell tower. These signals travel through the air and can be weakened by:

  • Distance from a tower
  • Thick building materials (brick, concrete, or metal)
  • Trees, hills, or geographic barriers
  • Weather conditions (rain, snow, or wind interference)

Metal, in theory, can reflect or absorb some signal energy. However, modern metal roofing systems are not continuous solid barriers they include seams, fasteners, vents, and other openings that allow radio waves to pass through.

In short, metal roofing might reduce signal strength slightly, but it’s rarely the main cause of poor reception.

What MK Roofing Sees in Montana Homes

As a local roofing contractor in Lewistown and Great Falls, we’ve replaced hundreds of roofs with standing seam and steel panel systems. Based on our first-hand experience:

  •  98% of homeowners report no noticeable change in cell service after installation.
  •  Signal boosters or Wi-Fi calling easily solve weak-signal areas.
  • Metal roofs often improve insulation and energy efficiency  without affecting daily connectivity.

We’ve even tested cell reception during installs  and found that cell signal typically remains stable indoors and outdoors.

Factors That Can Affect Cell Reception (More Than the Roof)

If you notice poor cell signal inside your home, it’s likely caused by one or more of these issues:

  1. Tower Distance: Rural Montana areas can be miles away from the nearest cell tower.
  2. Home Construction: Thick concrete, brick, or insulation materials can block radio waves.
  3. Carrier Network Coverage: Some providers simply have weaker coverage zones in central Montana.
  4. Device Age: Older phones may not support modern 4G/5G antennas effectively.

Tip: Before blaming your roof, test your phone’s signal outside or near a window. If it improves, you may just need a signal booster or mesh Wi-Fi system indoors.
