Welsh slate isn’t cheap. But it’s well-worth the cost of investment. It’s incredibly durable, long-lasting, and has a variety of other benefits. Let’s take a look at some of these now.

• Unbeatable durability – The average asphalt shingle roof will last somewhere between 10-30 years. Metal roofs can last up to 40 years, and concrete roofing tiles can last up to 50 years.
  Welsh slate, when properly maintained, can easily last over 100 years. In fact, there is a 100-year warranty on all of Welsh slate roofing materials! The quality of Welsh slate is so good that, after 100 years, about 50% of the slate material will still be in good enough condition to be reused! There is simply no other roofing material that can match the longevity of Welsh slate.
• Energy-efficient – High quality slate roofing is very dense. A slate roof can weigh anywhere from 350-750 kilograms. Because slate is dense, it helps your home become more energy efficient. It traps warm air in the winter, and helps prevent the escape of cooler air during the warmer months – resulting in lower energy bills!
• Low-maintenance – Natural slate is more durable than man-made roofing materials. It’s very dense and impermeable to water. It’s also non-combustible, so it is not a fire hazard. Because it is inert, it will also not be affected by fungus and mold, although algae may still grow in some cases. Copper flashing, usually used with slate roofs, lasts 70 years without maintenance. To maintain your roof, simply have it inspected after every winter, replace any broken tiles, and have it cleaned if algae or stains appear. That’s it!
