Anyone know how much asphalt roof shingles attenuate RX signals in an attic? Any experimentation with such?

Depends on the frequency and whether they are wet or dry. As long as there isn't metal foil under them you'll still get a reasonable amount of signal in most cases

Aluminum or steel siding on the attic wall exteriors will be a bigger problem than the roof. Same goes for foil backed sheathing used behind any siding.
