If you're looking at homes in downtown Richmond, you'll inevitably notice the beautiful slate roof tiles. But, if you're more familiar with asphalt shingles, you might be curious if buying a home with slate shingles is a good idea. Now let's dive into the pros and cons of slate roofs, their costs, and their lifespan.
A real slate roof is crafted from natural stone that has been quarried from sedimentary rock, cut, and drilled to create shingles1. Notably, this form of roofing is highly regarded and prized for its authentic beauty and exceptional longevity. Although they fall into two primary categories - hard slate and soft slate, Virginia homes typically only have hard slate.
Slate is a type of metamorphic rock that's formed under immense heat and pressure within the Earth's crust2. This unique formation process makes it a very dense, durable, and resilient material. Furthermore, the mineral composition of slate gives it its distinctive color, which can range from blue-grey to black or even green, red, or purple2. Accordingly, it's beauty comes not only from its color but also from its natural texture and slight irregularities - making each shingle one-of-a-kind.

Plus, the National Slate Association says some can last up to 150 years 1. This lifespan far surpasses that of most other roofing materials, making it a lasting investment. For example, the life expectancy of asphalt shingles is typically only around 20-30 years.

Slate is among the most expensive roofing materials available, both in terms of the material itself and the cost of installation3. For this reason, it is a significant investment, and homeowners should carefully consider their budget before choosing this option. However, the high cost is offset by its long life. In other words, although a new slate roof has a higher total cost than other roofs, it has one of the lowest costs per year of life.
Slate is a very heavy material, and not all homes can support the weight of a slate roof without additional structural support4. On average, they weigh about 1000-1500 pounds per 100 square feet. Although most new roof structures can accommodate the weight, some older structures need additional support first. Accordingly, homeowners considering a slate roof should have a structural engineer assess whether their home can handle the weight.
Installing a slate roof requires specialized skills, and not all roofers get trained in this area3. Plus, it's difficult to find a local roofing contractor to perform repairs and maintenance work.

These roofs can last over a century with regular maintenance and roof inspections. However, their actual lifespan primarily depends on the quality of the slate used and the installation process1. For example, high-quality stone installed by experienced professionals can result in a roof that lasts for generations.
Maintenance typically includes regular inspections, replacing damaged or missing tiles and checking flashings and other roof components. Hence, homeowners should plan for these ongoing maintenance costs when considering a slate roof.
