Your contractor should be protecting the curing process from the elements and extreme temperatures as part of their job.

Before we could even get the inspector in, the temperature hit 15 below zero one night after we made the offer, and although the property was winterized I found at least 3 places in the basement where the pipes split that night.  

@Dan Edwards  Temperatures here are over 100 in the summer and get down below freezing in the winter. 

But light gauge steel framed homes will withstand fire up to a temperature point, then they simply melt and collapse.  

This magical white goo will take the temperature of a roof in AZ from 200+ degrees (summer) down to about ambient air temp or below. 

=(I have stayed in an airbnb before where I had to stay in the guest bedroom and it was a NIGHTMARE not having control over the AC temperature as I did not have access to it at all.

You can educate your tenants on this.Once you have it serviced you can see if there was something that you feel you should give the tenants a allowance for.Ultimately you can tell them you have no control on the temperature, their thermostat settings etc.

Root causes for high humidity: too much moisture getting into the air, not enough ventilation, not enough air movement, low air temperature. 

I use a smart thermostat to let me know when the temperatures and humidity are out of range and it uses ifttt to notify me.

At the same time Bay Area temperatures hit 120 degrees.
