What is Slate Roofing?
Slate roofing created from tiles of premium, natural stone or synthetic tiles crafted to look like natural stone. It is the incredibly durable, fire-resistant, and aesthetically appealing – often found on high-end or historic homes.
Slate tiles are cut from slabs of stone, creating flat, rectangular tiles that interlock to form a waterproof barrier. Known for its long lifespan, slate is also resistant to severe weather conditions like high winds, heavy rain and the extreme heat of Central Texas.
Types of Slate Roofing
Natural Slate
Natural slate roofs are made from quarried stone. This type of slate is the most traditional and durable option.
However, because of the weight of natural slate, you may need to add structural support, which could cost an additional $2,000 to $5,000.
Synthetic Slate
Synthetic – or composite – slate is made from polymer-based materials or recycled rubber, mimicking the look of natural slate.
Synthetic slate is less expensive than natural slate. It is also lighter than natural slate meaning it is unlikely to require additional structural support.

What are the pros and cons of slate roofs?
Slate Roofing Advantages
Extreme Durability
Slate roofs can last up to 100 years or more due to their ability withstand extreme weather conditions, such as high winds, hail, heavy rain, and the excessive heat of Texas summers. However, large and/or high-impact hail can cause cracks, breaks or missing tiles.
Fire-Resistance
Slate is a non-combustible material, providing excellent fire protection.
Aesthetic Appeal
Slate offers a high-end, elegant look and is available in various colors.
Low Maintenance
Slate roofing requires minimal upkeep due to its long lifespan.
Slate Roofing Disadvantages
High Cost
Slate is one of the most expensive roofing materials, both in terms of material and installation.
Heavy Weight
Natural slate is heavy, and often requires additional structural support for the roof. However, synthetic slate is lighter and thus does not require additional structural support.
Tile Fragility
While slate roofs are overall incredibly durable, the individual slate tiles can crack or break if walked on or impacted by debris, such as hail or falling branches.
Difficult Installation
Installation is complex and should only be done by skilled professionals.
