Question

Does a metal roof block EMF

Answer 1

1. By shielding or preventing radio waves from the outside, metal roofs tend to reflect EMF.
2. No radio waves will get inside the house if you have protected doors and windows.
3. It's important to note that, because it's so good at preventing EMF radiation, any EMF radiation generated by devices within the house will bounce back and stay inside.
4. Therefore, we can conclude that a metal roof blocks EMF.
