Long-Lasting Roofing

Non-combustible material resistant to fire, wind and storms
Natural stone material that’s waterproof and leak resistant
Non-fading stone that holds colour
Resistant to chemical pollutants and acid rain

Environmentally safe construction
Resistant to impact damage and hail
Little to no maintenance requirements
Available in different shape combinations
Customizable sizes, textures and thicknesses

If you’re looking for a durable and long-lasting roofing material, slate roofing is the most reliable option available to you.
Types of Slate Roofing
Not only does slate roofing come in many colours, designs and shapes, it is also available in two distinct types:
Synthetic: Also called composite, synthetic slate displays the beauty of natural slate with extra durability and easier installation. Synthetic slate is composed of a polymer blend that is nearly maintenance free and lighter than natural slate, which reduces stress on your roofing support structure.
Natural: Natural slate has been around for centuries. Made of natural stone, this material is fireproof, waterproof and long-lasting. Natural slate is environmentally friendly, helps increase your home’s resale value and is a high density material that’s very durable.
Long-term Savings
Slate roofing may be expensive to install, but this is a one-time expense. With roofs that have lasted over 100 years, you’ll never have to replace your slate roof in your lifetime. That means no replacement fees down the road. Additionally, slate roofing requires little to no maintenance over its lifetime. Slate is made of natural or synthetic stone, making it resistant to impact damage, chemical pollutants, fire, wind and more. This resistance helps prevent cracks and leaks in your roof, which will prevent you from paying for maintenance and repair costs over the years.
