Slate has a timeless natural beauty that lends itself brilliantly to both modern buildings and period properties. It has increased longevity and is perfect for bringing out a more rustic quality to your home. Another terrific advantage slate has is its unmatched durability, and when installed properly and maintained well, a slate roof could last up to 100 years or longer. Water can’t penetrate slate, and it also won’t be affected by things like mold or fungus. In addition, slate is completely fireproof and able to withstand higher temperatures. These factors combined make slate roof tiles incredibly hard-wearing.
