Siding/Facade Repair Rec. Needed

Hi there, we have a facade made of cement board shingles that appear to have been knocked loose with all the 50 MPH+ winds the past few days. One small piece of the facade had already fallen off and another much larger piece is hanging off precariously. Unfortunately this is 3 stories up and not accessible from either the windows or the roof so we would need someone with a lift to reattach it. We are looking to get someone to come and repair ASAP as well as let us know if there is a better way to secure these for the future. Any pointers are much appreciated.
