The coaxial cable comes wrapped in shielding usually consisting of metal and plastic.
Metal roof antenna interference.
It would likely make a lousy antenna.
Another culprit for poor reception is reflective surfaces.
Thankfully there are special indoor antennae which will circumvent this problem and help you watch tv despite having metal roofs.
Another common place interference happens is from poorly shielded cables.
A coaxial cable is used to transmit an over the air signal from the antenna to your television tuner.
I sometimes use ham radio amateur radio as well.
On using a metal roof as an antenna the joints between panels are likely not soldered and are likely to form corroded diode junctions that generate rfi.
Shielding helps to reduce electromagnetic interference.
Thus buildings with a metal roof or many metal components will face difficulty watching tv.

Over the air antennas should never be placed in basements or in windows with metallic film security bars or mesh as this will obstruct signals.
I use rabbit ear tv antenna to receive tv programs.
Common sources of over the air tv interference.
With external antenna elevated a minimum of two feet from the metal roof you can be sure the reception will be captured and boosted.
Interference from cellular towers.
No one material will be the sole perpetrator.
If you have a metal roof for instance make sure the outdoor antenna is mounted at least one meter about 3 3 feet above it to reduce any effects of interference.
In a nutshell metal roof or not the type of building material is irrelevant the cell phone signal will be injected into the internal space via a special high quality cable.
Does metal roofing affect radio tv reception in the house.
A metal roof discourages the transfer of signal by reflecting it away from you.
Does metal roof affect any of these.
Generally if you do have poor cell phone service in your home it will be due to the cumulative effect of the materials used.
Beware too of radiant barriers if you ve mounted your tv antenna in the attic.
Don t trap your antenna with any type of interference.
However it is possible some blockage or scattering of signals may occur.
If you have aluminum siding or a metal roof be sure to mount the sky outside away from the siding or above the metal roof if possible.
My fm radio also has an antenna.
