 The rubber seals dry rot. Rubber seals can dry rot. Or actually, I saw the other day where a, we don't know if it was a limb or what, but there was an actual hole in the roof from something making impact with a roof. Oh, goodness. It could have been a limb because we didn't have some storms, but it would, it just looked like a dent. But looking hard enough, you could see there was a hole in there.
