What causes slate roofs to deteriorate?
There are a number of considerations that must be taken into account when inspecting a slate roof for repair, including flashing quality, nail and fastener type—and quality of the tiles, themselves. Often, the slate tiles have simply outlasted the other components. That’s not surprising when you consider that a galvanized nail can rust in 30 years, while slate can last for 150 years. Instead of complete replacement consider slate restoration A slate roof is not inexpensive, so you’ll want to avoid unnecessary costs. Any roofing contractor you choose to hire should do everything they can to reclaim slates that are in good condition and only replace those that cannot be reused.
