Question on building inspectors

[Michael King]

I ordered a building inspection for a 4 plex in St. Louis that I'm buying. At the time of booking, I asked if a roof inspection was included, which was an important deciding factor in using this particular company. They said it was included. On the day of the inspection, there was snow on the roof of the property and the inspector said he could not get on the roof, but he could inspect the roof from inside the attic. Odd, I thought. 

Roll the clock forward 2 days and I email the company to find out if they're going to do the roof inspection or whether I should expect a refund of any description. My realtor calls me to tell me the owner of the company said that there would be an additional charge to go back out to inspect it. 

Is it just me, or should I expect to receive services that I paid for? Or expect to be the one that gets screwed due to the weather?
