Yes, metal roofs can affect wireless signals, but only when the metal is extremely conductive.

Aluminum and copper are both highly conductive metals, so if you have a roof made out of one of these materials, it can affect your WiFi signal. However, most modern rooftops are covered in asphalt shingles or other less conductive materials.

If your roof is made up of metal, there’s nothing you can do to fix it. The only way to improve your WiFi signal would be to replace your metal roof with a different material.

If you’re worried about this problem affecting your home, try moving your router and testing the signal strength at different locations in the house. If possible, try moving it closer to where you’ll be using it most often (such as near your computer). If that doesn’t work, try placing it somewhere else on the first floor or basement of your house instead of upstairs where metal tends to be more prevalent.
