Identifying Slate Roof Damage

Homeowners know that the roof above their heads is vital for protection and comfort. Slate roofs are durable and long-lasting, but they are not immune to damage. Regular inspections are key to maintaining the integrity of a slate roof. Knowing how to identify damage can save time and money in repairs. This guide provides insights into spotting damages early on.
