Can you provide links for providers of this? We have exactly this problem.
We're in a fringe zone of SprintPCS (East Livermore, CA) and none of our
c-phones work inside the building. SprintPCS was supposed to do a buildout
this way, this year, but it isn't happening.

centers, and a thin Kate Moss looking yagi for each roof.

Actually, this should be a passive device. Various types of slotted
waveguide/coax are made, for example in the Heliax product line. An
antenna on the roof (directional antenna only if you're on 
the edge of a
coverage area) and a slotted line through your facility will provide
good results. Think about it for all commonly used 
frequencies (cellular
and pager) that might be in use in your facility. This isn't something
you have to get via your wireless vendor, and it doesn't need
electronics.

Hospitals have used such setups for years to permit doctor's pagers to
function throughout buildings (even in basements).
