You have to completely seal the roof. There's no ventilation so any water
that gets in has no place to go to evaporate.
It's apparently more common in Texas and Florida than here in the Chicago
area, but it's catching on. Studies show only a tiny increase in roof temp
and a tiny loss of shingle life without ventilation. Shingle manufacturers
vary in their responses, with some okaying the practice and some refusing
to warrantee any roof so installed, but shingle warrantees are a joke
anyway, so this is just one more way to get a claim refused. I'm using
100% coverage of high temp ice and water shield.
