Solar roof capacity vs. inverter capacity

Should the size of the inverters match the roof capacity?
We have a 14 kW roof. Our two inverters add up to 9 kW.

Im having a hard time seeing how the inverter ratings add up to 9kW. Are you adding the total of your inverter production together, or talking about your inverter ratings?

I suspect its the former (looking at your peak production) and not the later (telling us what your inverter ratings are). In either case, its perfectly normal for the inverter ratings not to add up to the total of the PV, but I would be surprised if you had inverter RATINGS that total 9.
