Why the Material Choice Matters So Much

A roof replacement is a significant investment, and the material you choose affects the cost, the look, the long-term performance and what maintenance the roof needs going forward. There is no single right answer for every home. The best material depends on your roof pitch, your property, your budget and how long you plan to stay.

Dereham Roofers works with homeowners in Mattishall and nearby villages to find the option that genuinely fits - not just the cheapest, and not necessarily the most expensive. Here is an honest breakdown of the main materials available.

Concrete Interlocking Tiles

Concrete interlocking tiles are the most widely used roofing material for UK homes built from the 1960s onwards. They are machine-made, consistent in size and widely available, which keeps costs down.

• Pros: Competitively priced (typically £40-£70 per square metre installed, though prices vary by roof complexity). Long lifespan - well-made concrete tiles can last 50 years or more. Good range of profiles and colours. Easy to source replacements if individual tiles are ever damaged.
• Cons: Heavier than some alternatives, so the roof structure needs to be adequate. Can look flat and utilitarian on older properties. Colour tends to fade over time, though modern through-colour tiles hold better than older surface-coated ones.

Concrete tiles are a solid, sensible choice for most standard pitched roofs and they suit the majority of post-war housing.

Natural Clay Tiles

Clay tiles have been used on English roofs for centuries and they remain one of the most attractive options, particularly on older properties and in rural settings. Plain clay tiles are also more appropriate than concrete on some buildings where planners may have a view on materials.

• Pros: Outstanding longevity - clay tiles routinely last 80 to 100 years. Colour is baked in and does not fade. Aesthetically sympathetic on period homes. Recyclable at end of life.
• Cons: More expensive than concrete, both for materials and labour (the smaller format of plain clay tiles means more tile-by-tile fixing). Harder to source exact matching tiles for future spot repairs. Heavier than interlocking concrete on a per-tile basis, so structural checks matter.

If you are replacing a roof on a traditional or older property and want the result to look right for the building, clay is worth the additional cost. On a modern house, the price difference over concrete rarely pays for itself in practical terms.

Natural Slate

Natural slate - Welsh, Spanish or Uruguayan being the most common sources used in the UK - is the premium end of pitched roofing. It is also one of the most durable materials available.

• Pros: Exceptional lifespan. Welsh slate roofs laid in the Victorian era are still sound on many houses today. Slim profile looks elegant. Appropriate for listed buildings and conservation areas where planners often require natural materials.
• Cons: The most expensive option. Welsh slate costs significantly more than Spanish or Uruguayan grades, though all natural slates cost more than concrete. Not all slates are equal in quality - lower-grade imported slates have a shorter lifespan and can delaminate within 20-30 years. Fixing requires proper skill; poor nailing causes premature slipping.

Natural slate is the right choice where the building demands it or where you want the longest possible lifespan. For a standard semi-detached, the premium is hard to justify purely on functional grounds.

Artificial Slate

Artificial or synthetic slates are made from fibre cement or reconstituted stone and are designed to give the look of natural slate at a lower cost.

• Pros: Less expensive than natural slate. Consistent in size and thickness, making installation straightforward. Lighter than natural slate, reducing structural load.
• Cons: Lifespan varies considerably by manufacturer and grade - some perform well for 30-40 years, others fade or become brittle much sooner. The look does not quite replicate natural slate on close inspection. Replacement tiles may not match if the product line is discontinued.

Artificial slate can be a reasonable middle ground, but the quality range is wide. Ask to see the manufacturer's test data and check independently how their products have performed over time.

Flat Roof Systems

Flat or low-pitched sections of a roof - on extensions, bay windows or outbuildings - need a different system entirely. The two main options used today are torch-on felt (sometimes called built-up felt) and EPDM rubber membrane.

• Torch-on felt: A two or three-layer system of modified bitumen sheets bonded with heat. Well-established, widely understood by roofers and cost-effective. Typically lasts 15-20 years when properly installed.
• EPDM rubber: A single-ply rubber membrane bonded to the deck. Very durable - manufacturers quote lifespans of 30-50 years. Highly resistant to UV and temperature variation. Slightly higher upfront cost than felt but lower long-term cost when lifespan is factored in.

For a flat section being replaced as part of a wider roofing project, EPDM is worth considering for the longer service life. For a straightforward, budget-conscious replacement, torch-on felt remains a dependable choice.

Underlay: The Hidden Choice That Matters

Whichever tile or covering you choose, the underlay beneath it is equally important and often overlooked in conversations about material options. Modern breathable membrane underlays (sometimes called vapour-permeable underlays) allow moisture vapour to escape from the roof structure, which reduces the risk of condensation and timber deterioration. They are now standard practice on new roofs and replacements.

Original bitumen felt underlays from pre-1990 roofs are not breathable. When a roof is stripped and replaced, fitting a modern breathable underlay is straightforward and well worth doing. It is one of those choices that costs little extra at the time of replacement but pays for itself in reduced maintenance over the years.

What to Ask Before You Commit to a Material

Before agreeing to a replacement, ask your roofer these questions:

• Is this material appropriate for my roof pitch? Some tiles have minimum pitch requirements.
• Will the roof structure support the weight of the chosen material?
• Is this tile readily available for future repairs, or could it be discontinued?
• What grade or origin is the slate, and what does the supplier say about its lifespan?
• What underlay are you using, and is it breathable?

A roofer who can answer these questions clearly and without deflecting is giving you what you need to make an informed decision.
