Concrete at ridges helps keep out water, roof tiles are nailed, the ones
ive seen, not caulked.


I don't know if it is a regional variation or not. But the roof tiles I
have are not nailed. They have nail holes at one end, but not used. I see
that the tar paper (still seem to be in good shape after 10 years)
underneath. Then the roof tiles are sort of "loose" sitting on top of
several big blobs of concrete cement. I think it used to be not loose but
Wilma knocked them loose?
