I'm not a fan of heat, but I much prefer to roof with tar paper/ roofing felt, and asphalt when it hot. They set and bond so much better.
I guess I think that there is tar paper and there is tar paper. I've seen some that weren't much thicker than normal paper (like that's going to last...), and there is roofing felt that is an 1/8" thick.
There are a number of homes around here that have been reroofed with synthetic underpayment and glass solar tiles. I will be interested to see the longevity of those roofs. A couple to my eye at least are already in trouble four or so years into their life span, as the tiles are lifting and forming gaps. (I think it looks dilapidated, like an asphalt shingle roof that is so old that the shingles are wearing off.) I suspect that the roof structure wasn't strong enough and the beams are settling/warping under the new load, but however it is caused, there are now gaps for water, dust, and insects to get in.
All the best,
Peter
