Seller blocked inspector

We requested a roof inspection due to some concerns that arose during our primary inspection. So roofing inspector shows up today to the house as coordinated with seller only to find that a car is parked in the garage in a way that blocks access to the attic. House is vacant and no car was in the garage yesterday. Just signed the paperwork to cancel the contract. I am not playing these games.

EDIT FOR CLARIFICATION: I intentionally made the original post short to avoid the books I see so often which meant I left out some of the details. For those interested I edited and added them below.

The inspection revealed water stains in the attic. The home inspector stated he could not determine where they came from or how recent they were and recommended a roof inspection to determine the cause of the stains. We reached out to the seller to request an extension to the inspection period baed upon this information. It was denied and since we still had a few days left we moved forward with scheduling the roof inspection. We informed the the seller's agent of exactly when the inspection was scheduled and what the inspector needed to do. The house is vacant and during the tour and inspection no vehicles were at the house. The roofing inspector went on the roof and did an inspectionof the outside and when he tried to enter the attic found that a car was parked in the garage in a very unnatural way. It was dead center of a 2 car garage and pulled all the way in so that there were inches between the fron biumper and the back wall of the garage. This meant the car had driven over a curbinside the garage to get that close. Our inspector reached out to our agent who tried to contact the seller's agent who did not respond. The instpector did what he could without accessing the attic and left. Late last night the seller's agent finally responded and said that the seller had just stopped by to check on the pool and didnt realize they blocked the access. We again asked to extend the inspection period to try to get someone back out there to finish the inspection, but were told the period goes until Monday so there is no need to extend it. We are doubtful we cn get someone out there over the weekend and rather that risk our funds in escrow we elected to move on from the purchase.

Is it possible that the bloackage was an accident? Yes. Is it also possible that the seeler did it intentionally to try to run out the inspection period? also a yes.

The bottom line is that I did not allow my emotions over liking the house override my sense that something was just not right and decided to walk away. I wish the sellers the best of luck and hoipe they find a buyer. It just won't be me. SOme of the posters here may disagree with my decision and that is their right. When they are dropping half a million dollars on a piece of property they can make their own decison on how to proceed. For me, this was the right way. I dont regret it at all and am happy to say that we toured other homes last night and found another one we like even better.
