Deciding which roofing material to select for your home is a major investment, which impacts everything from protection against the elements to resale value and aesthetic appeal. Two of the most common roofing systems chosen by many homeowners today are slate roof tiles and asphalt shingles. With unique features, each roofing option caters to various needs, budgets, climates, and regions.
Let’s break down the benefits, drawbacks, and differences between a shingle vs slate roof to help you make an informed decision about your next roof replacement.
A slate roof consists of overlapping slate tiles made from natural stone, often quarried from regions rich in fine-grained metamorphic rock. Slate shingles are considered an expensive roofing material due to their high installation costs and the specialized skills required for slate tile roofing. As a durable roofing product, slate’s longevity is above average. When properly installed, these roofs can last over a century.
Characteristic advantages of slate roof tiles include:
The asphalt shingle roof is the most widely used roofing system in all of North America, owing to its low cost, ease of installation, and aesthetic qualities. Asphalt roof shingles are made from a fiberglass or organic mat that’s soaked with asphalt in the production process and coated with mineral granules. Variations include 3-tab asphalt tiles, laminated asphalt shingles (also known as architectural shingles), and specialty products for increased UV protection and wind resistance.
Asphalt roof options stand out because:
When comparing installation costs and requirements for a slate roof vs a shingle roof, the difference is substantial.
Slate roofs, when properly installed, can endure 75–150 years or more, with some historical properties still boasting their original slate roof tiles. These tiles are:
Asphalt shingles, which include advanced laminated asphalt shingles, generally need replacement within 15–30 years, depending on the quality and exposure.
Synthetic slate roofs provide some of the visual advantages of natural slate but are lighter, less expensive, and easier to maintain, although they do not match true slate’s longevity.
Apart from function, aesthetic appeal is a major reason many homeowners choose their roofing material.
Sustainability and energy efficiency are increasingly influential in roofing decisions.
Composed of natural stone with minimal processing, slate roofs generate low greenhouse gas emissions compared to alternative materials. They are energy efficient due to their thermal mass, which helps stabilize interior temperatures during extreme fluctuations. At the end of their service life, slate tiles can be reclaimed or repurposed, making them an environmentally friendly roofing option.
The manufacturing process for asphalt shingle roofs involves petroleum and energy-intensive steps, contributing to higher greenhouse gas emissions compared to slate. While asphalt roof tiles provide adequate insulation, they are less energy efficient than slate, which benefits from its natural thermal mass. Although old asphalt shingles can be recycled, many still end up in landfills. Still, newer programs are improving sustainability by repurposing them for road construction and as additives in other roofing products.
Maintenance needs and replacement costs should be considered alongside material qualities.
Slate roofs are widely regarded as low-maintenance roofs, but slate requires that broken or missing tiles be replaced immediately to prevent water ingress. Maintenance is generally limited and, if needed, requires skilled professionals. Replacement costs are high, but infrequent.
Asphalt shingles are easier and cheaper for repairs, but require more frequent repairs as shingles get blown off or damaged more frequently in heavy storms. This can increase cumulative replacement costs over time.
Slate shingles and slate tile roofing stand up exceptionally well in regions with strong winds, heavy rain, snow, and extreme temperature fluctuations. They are highly resistant to fire and rot, making them suitable for diverse climates.
Asphalt shingle roof systems can provide strong protection but may suffer from wind uplift or UV degradation if improper installation occurs or material quality is low. High-quality, energy-efficient shingles with enhanced UV and wind resistance are increasingly available.
| Feature | Slate Roof Tiles | Asphalt Roof Shingles |
| Lifespan | 75–150+ years (natural stone) | 15–30 years (with regular replacement) |
| Upfront Cost | High (expensive roofing material) | Low–Moderate |
| Maintenance | Minimal but requires specialized skills | Occasional, generally easy |
| Environmental Impact | Low emissions, recyclable | Higher emissions, potential recyclable |
| Durability | Excellent, highly resistant | Good, but lower than slate |
| Weight | Heavy; may need structural reinforcement | Lightweight; fits most roofs |
| Appearance | Timeless beauty increases resale value | Flexible; mimics other roofing materials |
| Labor Costs | High (specialized skills, complex installation) | Lower (widespread skill base, quick installation) |
When deciding between a slate roof vs shingle, or even other roofing materials, consider what matters most to you. If you’re after timeless elegance and a lifetime investment, slate’s high installation costs and labor are often well worth it. However, if budget and flexibility top your list, shingles offer affordability and easier replacements, making them a smart choice for many homeowners.
