Today we had a thunderstorm. The agency that I work at is made up of nine buildings and we had a few leaks. Even though it has been “fixed” a few times, my parent’s roof leaked around the fireplace as usual. My girlfriend is into real estate management and helps take care of different kinds of buildings and she says that roof leaks are a fairly common problem in all of her buildings, regardless of thier age or building type (Her old metal warehouses leak, her newer class A office buildings get leaks). When I bought my first house and was trying to figure out the whole home insurance thing- I asked homeowners if they have ever used their home owner’s insurance and what they used it for. It seemed as if a lot of people who had to use their insurance reported that thier roofs leaked.
I figure that we humans have been making roofs for quite a while now. We have even been making relatively leak free boats for some time now as well.
With all this time to try different things, why do roof leaks seem to be such a common problem? I realize that for every roof that leaks, there are many more that do not. I also realize that heat, wind, and rain take a toll on materials over time, but what is it about building roofs that is so difficult? Is it just a cost thing?
