I'm looking to replace by asphalt shingles roof with another medium that would also provide a benefit of shielding my house from EMF/RF radiation. Does anything have any info on effectiveness of metal roof in this regard? I'm trying to decide if the added cost of metal roof is worth it or if I should stick with cheaper asphalt shingles and add a [probably much cheaper] EMF shielding underlayment.
If someone here has any experience with EMF-shielding roofing/underlayment materials, please do share.
Metal is fantastic for shielding purposes. Just ask anyone that has put a metal roof on their home and tries to get a cell phone signal. I have neither tested or used the EMF underlayments. I suspect they are effective, but there are a great many other benefits to metal roofing here.
Sounds like cell phone signal reception is a downside of metal roofing. Probably the roof also reflects the cell signals, leading to multipath reception.
