 Yeah, they can dry out. They get brittle or almost like tar light too. Especially here in Alabama. And so I had them come out. I took advantage of the free roof inspection. And they said, hey, it looks okay, but if I were you, it's just a suggestion, I'd go ahead and replace the screws. Because they need to be replaced every so many years anyway. So I had a couple dollars in my pocket. I said, let's do it. They gave me an estimate. They stuck by that estimate to the penny. They showed me a few screws that I had issues with. But they were done in like, what did I say, a little over a day.
