GPS transparent Roofing material

[Akshay Jaiswal]

hello,
Can anyone suggest me some roofing material through which GPS signals can penetrate.
The material should be such that it should not affect the positional accuracy.

All roofing materials will attenuate GPS signals to some extent, so the best you can do is to select a material with the lowest attenuation, avoid any metal materials of any kind as this will have a very high attenuation
