The Ultimate Guide to Slate Roofing

Residential slate roofing is one of the most durable, aesthetically pleasing luxury options a homeowner can make.

That said, It's also a significant investment and proper installation from an experienced professional is tantamount to ensuring its longevity.

Whether you're considering installing a new slate roof or repairing your current one, this ultimate guide will provide you with everything you need to know about slate roofing.

We are going to cover everything: advantages, maintenance requirements, how to find the right contractor, and more!

Let’s start with something basic:

What Is Slate Roofing?

Slate is a roofing material made from either:

  • natural slate

  • synthetic materials made to imitate the look and characteristics of natural slate

For this blog, we will be focusing on NATURAL slate roofing…

If you are interested in diving deep into the benefits of synthetic slate, check out this blog we wrote about it last week!

Back to the topic…

Natural slate is a metamorphic rock formed over millions of years after layers of volcanic ash and clay are subjected to intense pressure and heat.

As a result, Slate is formed!

The resulting rock is incredibly durable, non-combustible, and resistant to water and weather damage, making it an ideal roofing material.

Another aspect of natural slate that makes it excellent as a building material is its variety!

Slate comes in a variety of colors, thicknesses, and sizes, providing homeowners with a wide range of options to choose from based on their personal preferences and the architectural style of their home.

History of Slate Roofing:

Considering how natural of a material it is, it comes as no surprise that slate has been used as a roofing material for centuries, starting in medieval Europe!

Slate as a roofing material was first documented in North Wales in the 13th century, where it was used to roof castles and other high-class structures(this stuff was expensive!)

Over time slate roofing spread throughout Western Europe, especially where slate deposits were abundant, like Spain, France, and Germany.

In the US, the first slate quarry opened in 1785 but didn’t become popular until the early 19th century, when more slate deposits were found in the Northeast.

Following this, Slate roofing was used on many of the region's iconic buildings and homes.

Today, slate roofing continues to be a popular choice for homeowners & architects looking for a durable, luxurious option.

Benefits of Slate Roofing: Lifespan

One of the BEST aspects of a slate roof is its exceptional lifespan.

When properly installed by a trained professional, a slate roof can last for up to 100 years or more!

For context, a typical asphalt shingle roof has a lifespan of 20-30 years, and that is with regular, costly maintenance.

This longevity makes slate roofing a wise investment for homeowners, as it can save you money in the long run on repair and replacement costs.

Furthermore, slate roofs require minimal maintenance and are highly resistant to weather and environmental damage, reducing the need for repairs and prolonging their lifespan.


Slate roofing is renowned by architects worldwide for its exceptional durability, which is one of the primary reasons why it has been used as a roofing material for centuries.

Natural slate is an incredibly dense and durable material that is highly resistant to:

  • Water damage

  • Fire damage

  • Severe weather damage

Unlike most residential roofing materials, slate is non-combustible and can withstand extreme temperatures, making it a safe and reliable choice for homeowners in wildfire-prone regions.

Additionally, slate is resistant to:

  • mold

  • mildew

  • Insect damage

This means that slate requires minimal maintenance and can last for decades without needing repair or replacement.

Overall, the exceptional durability of slate roofing provides homeowners with a long-lasting, reliable, and low-maintenance roofing solution that is well worth the investment.

Energy Efficiency

In addition to its exceptional durability, slate roofing also offers huge energy-efficient and cost-saving benefits for homeowners!

Slate is a natural insulator that helps regulate indoor temperatures and reduce the need for heating and cooling, which can lead to significant energy savings over time.


Due to the slate's dense composition and non-porous surface, it helps prevent air leaks and keep the home well-insulated, keeping energy costs down.

While slate roofing may have a higher upfront cost compared to other materials, its energy-efficient and cost-saving benefits can make it a stellar investment for homeowners in the long run.


Aside from its functional benefits, slate roofing is also prized for its stunning visual appeal.

Natural slate comes in a variety of colors and textures, ranging from deep grays and blues to warm browns and reds, allowing homeowners to choose a roof that complements the style and character of their home.

The natural variation in color and texture of slate also adds a unique and distinctive look to each roof, making it a popular choice for architects and homeowners who value individuality and craftsmanship.

Additionally, slate's clean lines, subtle curves, and sleek profile create a clean and sophisticated look that enhances a home's curb appeal and overall value.

To demonstrate just how much value a slate roof can bring, let’s look at a statistic from the 2023 National Association of Realtors Remodeling Impact Report

“99% of realtors polled agreed that curb appeal was crucial for improving a home's sellability.”

Curb appeal is crucial, and a slate roof can bring your home to the next level!

Whether a homeowner wants to restore a historic home or add a touch of elegance to a modern residence, slate roofing offers a versatile and visually stunning solution.

Disadvantages of Slate Roofing

While slate roofing provides many benefits, there are some potential downsides a homeowner needs to consider.

One of the primary concerns with slate roofing is its weight.

As we’ve mentioned, slate is a dense material, which brings a host of benefits, but also some potential problems.

For context, slate can weigh up to 1,500 pounds per 100 square feet, meaning the roof structure must be strong enough to support the weight.

This can make slate roofing more expensive to install when compared with other roofing materials, as the roof structure may need to be reinforced or replaced.

Additionally, slate roofing can be more pricey than other roofing materials due to the cost of the slate itself and the specialized labor required for installation.

However, it's important to note that the higher upfront cost of slate roofing is often offset by its long lifespan and energy-efficient properties.

That being said, it’s crucial to choose a specialized, licensed contractor to ensure that the slate roof is installed correctly and to the highest standards.

A good contractor will be able to assess the structure of the home and determine if it can support the weight of a slate roof, as well as provide an accurate estimate of the costs involved.
