When I bought my villa last year, I was in the same boat. I ordered my roof first in December because there was a rebate available ($500) on the HVAC in April. My unit already had an issue and freon was added to put a temporary bandaid on the problem.
Something else you should know, I ordered my roof in December but it wasn’t installed till April because of a “shingle shortage”. My roof was not damaged but was 21 years old and when purchasing the house it was difficult to get insurance.
Having just been through it, I’d recommend you order the roof and get the HVAC as soon as possible. Hotter weather is coming.
