What’s the Difference Between Felt, Liquid, and Slate Roofs?
Introduction
When it comes to choosing a roofing system for your home or commercial property, the wide range of materials available can make the decision overwhelming. Each roofing type offers its own advantages and is best suited to specific roof shapes, budgets, and property requirements. Among the most commonly used in the UK—especially in areas like Maltby, South Yorkshire—are felt, liquid, and slate roofs.
At EFG Roofing Maltby, we often get asked about the differences between these materials, and which is best for a particular project. This blog provides a detailed comparison to help you make an informed decision, whether you’re installing a new roof or replacing an existing one.
Felt Roofing: Affordable and Versatile
Felt roofing has long been a reliable choice for flat roofs, extensions, sheds, and garages. Traditionally made from bitumen-based sheets, felt roofing systems are now available in more durable, torch-on versions that are bonded using heat for improved waterproofing.
Benefits of felt roofing:
- Cost-effective: One of the most budget-friendly roofing options
- Quick to install: Especially on small-scale projects
- Lightweight: Ideal for timber-framed structures and flat roofs
- Easy to repair: Damaged sections can be patched or overlaid
Things to consider:
- Shorter lifespan than slate or liquid systems
- Can be vulnerable to UV degradation and blistering over time
- Less visually appealing for high-end residential projects
Felt is best suited to flat or low-pitched roofs where affordability and simplicity are the priority.
Liquid Roofing: Seamless and Durable
Liquid roofing is a modern solution that involves applying a waterproof liquid membrane directly to the roof surface. Once cured, it forms a seamless, highly durable protective layer that’s ideal for flat or complex roof shapes.
Advantages of liquid roofing:
- Completely seamless: Eliminates joints where leaks typically occur
- Excellent adhesion: Bonds well to felt, concrete, metal, and other surfaces
- Fast application: Can be applied quickly and cures within hours
- UV and weather-resistant: Withstands harsh British conditions
Points to note:
- Higher initial cost than felt
- Surface preparation is key: Poor prep can affect adhesion
- Primarily used on flat roofs, balconies, or roof refurbishments
Liquid systems are ideal for flat roofs needing a high-performance, long-term waterproofing solution, especially in exposed locations like South Yorkshire.
Slate Roofing: Traditional and Long-Lasting
Slate roofing is widely regarded as one of the most prestigious and durable options available. Natural slate has been used for centuries in the UK, offering a timeless appearance and incredible resistance to weathering.
Benefits of slate roofing:
- Exceptional longevity: Can last 80–100 years with proper care
- Natural material: Sustainable and visually elegant
- Fire-resistant and impermeable
- Adds value and character to period and high-end homes
Considerations:
- More expensive due to material and labour
- Heavy: Requires a strong supporting structure
- Installation complexity: Best handled by experienced roofers
Slate is ideal for pitched roofs, particularly on character properties or homes where appearance and lifespan are a top priority.
Comparing the Three Roofing Types
To help summarise the key differences between felt, liquid, and slate roofing, here’s how they compare on the factors that matter most:
Durability
- Slate: Highest durability, can last a century or more
- Liquid: Long-lasting with proper installation, typically 20–30 years
- Felt: Lower lifespan, usually 10–20 years depending on quality
Aesthetics
- Slate: Excellent, ideal for visible and heritage properties
- Liquid: Neutral appearance, not intended to be decorative
- Felt: Functional but less attractive
Suitability
- Slate: Pitched roofs on residential and heritage properties
- Liquid: Flat roofs, complex shapes, roof refurbishments
- Felt: Flat roofs, sheds, garages, cost-sensitive projects
Maintenance
- Slate: Low maintenance once installed
- Liquid: Minimal maintenance required
- Felt: May require more frequent patching over time
Choosing the Right Roof for Your Property
The best roofing system for your property depends on several factors, including:
- Roof shape (flat or pitched)
- Budget and long-term value
- Aesthetic preferences
- Weather exposure and insulation needs
- Intended use of the space below (e.g., living area vs storage)
At EFG Roofing Maltby, we take the time to understand your property, budget, and expectations before recommending a tailored roofing solution.
Conclusion
Felt, liquid, and slate roofs each offer unique advantages—and the right choice depends on your priorities. If you need a quick, budget-friendly solution for a flat roof, felt might be your answer. If you’re looking for a seamless, high-performance coating with excellent durability, liquid roofing is worth considering. And if you want a premium finish with long-term reliability and heritage appeal, slate is second to none.
