It is viable that you put up your property for sale, and people who are interested will come and inspect the entire house - from the garage to the roof. The roof is the focal point for any kind of home inspection. Once the person finds damages in the roof he can act in both ways. The buyer can walk away straight from the property and decide for a house with solid roof construction. On the other hand he can stick to the property and offer a reduced cost which much less than the actual market price.
