Slate roofing offers a strong option for homeowners who want a long-lasting, good-looking roof. It can last up to 200 years, much longer than regular asphalt shingles. The main drawback is the high cost, between $20 to $40 for each square foot, and you'll need to check if your house can handle its heavy weight. Slate won't catch fire and stands up well to bad weather, which adds to its worth. You'll need to take good care of it to make it last, though. Before choosing slate, think about whether you can afford it and if your house is strong enough to support it. Looking closely at its benefits, how it's put on, and what it takes to maintain it will help you make the right choice.

What Is Slate Roofing?

Slate roofing stands out among roofing materials because it's made from real stone, cut from the earth and shaped into thin, strong tiles. These natural slate tiles not only last a very long time but also look beautiful, making them a popular choice for many homes.
What makes slate roofing special is how long it lasts – anywhere from 75 to 200 years. This is much longer than regular asphalt shingles, which need to be replaced every 20 to 30 years. While slate costs more upfront, its long life makes it worth thinking about for homeowners who want a roof that will last.
Before choosing slate, there are some things to think about. It's very heavy – weighing between 800 to 1,500 pounds for every 100 square feet. This means you need experts to put it on, and your house must be strong enough to hold all that weight.
While slate gives you many choices in look and color, and will last longer than most roofs, it's important to carefully think about the cost and work needed to install it.
Benefits of Slate Roofing
Slate roofs come with many benefits that go far beyond how long they last. While regular asphalt shingles typically last 20 to 30 years, slate roofs can stay strong for 75 to 200 years. This amazing lifespan makes slate a smart investment that gives homeowners lasting value and security.
Slate also won't catch fire, which makes it perfect for homes in areas where wildfires are common. The look of slate adds beauty to any home – it comes in many colors and patterns that can make a house stand out and boost its selling price.
These roofs also handle tough weather well, standing up to strong winds, hail, and heavy snow loads. This means they protect homes in all kinds of weather.
As a natural stone product that can be reused, slate is better for the environment than man-made roofing materials. When you look at all these benefits, it's clear why slate roofing makes such a smart choice for homeowners who want lasting quality.
Potential Drawbacks of Slate

Slate roofs look great and last long, but they come with some real problems worth thinking about. The biggest issue is the high cost – you'll need to pay $20 to $40 per square foot, which is much more than regular roofing materials like asphalt.
The weight of slate is another big concern. At 800 to 1,500 pounds per 100 square feet, slate is very heavy and often needs extra support built into the house structure. This means more work and higher costs during installation and makes future repairs more difficult.
Slate tiles can also break easily if something hits them. Workers need to be very careful when putting them in or fixing them, which adds to the overall cost. Not many roofers know how to work with slate properly, so finding the right person for the job can be hard and expensive. This specialized skill set is crucial for professional installation and ensuring the longevity of the roofing project.
These problems can be summed up as:
Problem | Result |
---|---|
High Cost | Large payment needed upfront |
Heavy Weight | Extra support needed |
Easy Breakage | Risk of damage |
Special Skills | Few qualified workers |
Limited Warranty | Depends on contractor |
Installing Slate Roofing
Putting in a slate roof needs careful planning since slate is both heavy and easy to break. Each 100 square feet of slate tiles weighs between 800 to 1,500 pounds, so you must check if your house is strong enough to hold it. You might need to make your roof stronger before adding slate.
It's important to hire skilled roofers who know how to work with slate, as these tiles need special handling to look good and work well. If not installed correctly, the tiles can break or crack, which ruins both how the roof looks and how it protects your house.
A slate roof usually costs between $10 to $25 for each square foot, plus extra costs for the layer underneath and any needed support work. While the starting cost is high, a well-installed slate roof lasts so long that it's often worth the money.
Getting the site ready and using the right methods are key to avoiding problems later. When done right, a slate roof not only looks beautiful but also keeps your house safe for many years. Additionally, considering the roof's age before installation can help assess long-term durability and maintenance needs.
Key Maintenance Tips

A well-kept slate roof will last longer and work better, so it's important to check and fix problems regularly. Look over your roof at least twice a year to catch broken or missing pieces early, which helps avoid bigger, more expensive repairs later.
Make sure to check your roof after big storms to spot any harm from fallen tree branches or hail. Quick fixes help stop small problems from getting worse.
Keep gutters and downspouts clean and clear so water can flow properly. When water can't drain, it builds up and can hurt your roof's structure. Clean off any moss and algae growth too, since these trap water that can weaken the slate over time.
When your roof needs repairs, get help from skilled workers who know how to handle delicate slate tiles. These experts can fix problems without causing more damage, helping your roof investment last longer.
Following these basic care steps will help your slate roof stay strong and protect your home for many years.
Choosing the Right Contractor
Finding the right contractor for slate roofing can make a big difference in how long your roof lasts and how well it works. Since slate can last for many years, it needs to be put on correctly from the start.
Look for a contractor who knows how to work with slate – many roofers don't have experience with this special type of roof. Take time to look at their past work.
Make sure you get a good warranty to protect yourself if problems come up later. Pick contractors who clearly explain their warranty and show proof of their skills.
Also, ask for names of past customers and check what they say about the contractor's slate roofing work.
Your contractor needs to check if your house can hold slate roofing. This check is important because slate tiles weigh much more than regular roofing materials.
Get price quotes from several contractors to help with the high cost of slate roofing – this way you can find a fair price while still getting good work.
When selecting a contractor, ensure they have liability insurance coverage to protect against potential risks during the installation process.
When you find the right contractor, they'll help make sure your slate roof is put on properly and lasts a long time.
