Why Material Choice Matters More Than Most People Realise

When a new roof is being specified - whether for a house, an extension, a new build or a loft conversion - the material you choose affects everything from how long the roof lasts to whether planning permission is granted. There is no universally "best" option. Each material has genuine advantages and real drawbacks, and the right answer depends on your property, your budget and what the local planning authority will accept.

We install new pitched and flat roofs for homeowners in and around Newmarket. Here is a straightforward look at the main materials available and what you should consider before deciding.

Concrete Interlocking Tiles

Concrete tiles are the most widely used roofing material on UK housing and for good reason. They are manufactured to consistent dimensions, relatively affordable, and available in a wide range of profiles and colours.

• Lifespan: A well-laid concrete tile roof typically performs for 30-50 years, though the surface coating weathers within 10-20 years and the tile becomes more porous over time.
• Cost: Generally the most cost-effective option per square metre for a pitched roof, both in materials and fixing time.
• Weight: Heavier than slate. The roof structure must be assessed to confirm it can carry the load, particularly on older properties or extensions.
• Appearance: The range of profiles and colours is broad, but they do not replicate the texture of natural slate convincingly. Some planning authorities in rural or conservation areas will not accept them where natural materials are required.
• Maintenance: Moss growth is common as the surface ages and becomes more porous. Periodic treatment helps but does not reverse surface weathering.

Natural Slate

Natural slate is one of the oldest roofing materials in use and still regarded as the premium choice for pitched roofs where appearance and longevity are priorities.

• Lifespan: Good quality natural slate - Welsh, Spanish or Brazillian - can last 80-100 years or more when properly installed and maintained. The quality of the slate itself varies significantly between sources.
• Cost: Considerably more expensive than concrete tile in material cost. Welsh slate is among the most expensive but is widely regarded as the highest quality. Spanish and Brazilian slates offer a lower price point but vary in consistency.
• Weight: Natural slate is lighter than most concrete tiles, which can be an advantage on older structures with more modest roof timbers.
• Appearance: The natural variation in colour and texture cannot be replicated by manufactured alternatives. Planning authorities in conservation areas almost always accept natural slate and often specify it.
• Maintenance: Individual slates can crack or delaminate over time, particularly on roofs approaching 50 years old. Like-for-like replacement is straightforward where slates are available, but matching old Welsh slate can be difficult and expensive.

Fibre Cement Slates

Fibre cement slates (sometimes called artificial or synthetic slates) offer a middle ground between concrete tile and natural slate in both cost and appearance.

• Lifespan: Manufacturers typically describe lifespans of 30-50 years for modern fibre cement products. Earlier generations of the product (asbestos-cement slates, now removed wherever found) were a different material entirely.
• Cost: Lower than natural slate but higher than concrete tile. A reasonable balance where slate appearance is preferred but budget is a constraint.
• Weight: Lighter than concrete tile, comparable to or lighter than natural slate depending on the product.
• Appearance: Better than concrete tile at mimicking slate, but still distinguishable close-up from the real thing. Some planning authorities accept them; others do not in conservation areas or on listed buildings - always check before specifying.
• Maintenance: Low maintenance in normal use. Some products can develop surface algae over time.

Clay Pantiles and Plain Tiles

Clay tiles come in two main forms: the curved pantile, which gives a distinctive ridged profile, and the plain tile, which is smaller and lapped in double courses.

• Lifespan: Well-fired clay tiles are extremely durable. Roofs tiled with good clay plain tiles can last well over a century in good condition.
• Cost: More expensive than concrete tile in materials. Plain tiles require more tiles per square metre than interlocking types, which also affects labour cost.
• Weight: Plain clay tiles are among the heaviest roofing materials. Structural assessment of the roof timbers is essential.
• Appearance: Traditional and highly valued in areas where clay tile is the local vernacular. Planning authorities in conservation areas and on listed buildings frequently require clay tile where the original material was clay.
• Maintenance: Clay itself does not degrade the way concrete does, but the mortar bedding on ridge and hip tiles does need attention over time.

Flat Roof Materials - Felt and EPDM Rubber

For extensions and flat-roofed structures, the two main systems in common use are built-up felt and EPDM rubber membrane.

Traditional three-layer built-up felt is the most established system and remains cost-effective. The layers are torched or bonded together and the finished surface is durable in normal conditions. However, felt is vulnerable to blistering in heat and cracking at joints over time, and a lifespan of 15-25 years is realistic for a well-laid felt roof before it needs replacing or recovering.

EPDM (ethylene propylene diene monomer) rubber membrane is a single-ply system bonded to the roof deck. It is highly flexible, handles temperature extremes well without cracking, and is less prone to blistering than felt. EPDM is typically described as having a longer service life than felt, with many products described by manufacturers as lasting 40-50 years under normal conditions, though actual performance depends heavily on the quality of installation, particularly at seams and edges. It tends to cost more than felt upfront but can represent better value over the full life of the roof.

Planning Conditions in Newmarket

Planning conditions or conservation area designations may limit the materials you can use. If you are replacing a roof on a listed building, or in a conservation area, the local planning authority may require like-for-like replacement or specify particular materials. Always confirm what is required before buying materials or instructing a roofer. We can advise on what tends to be accepted and flag cases where you should check with the planning authority directly before proceeding.

What to Ask When Getting Quotes

Before accepting any quote for a new roof, ask the roofer to specify exactly which material they are pricing, including the profile and source of tile or slate. Ask whether the battens and underlay are included in the price (they should be). Ask whether the ridge and hip details are mortar-bedded or dry-fixed - dry-fix systems are less likely to crack and lift over time and are now standard practice on new roofs. A quote that does not specify these details cannot be meaningfully compared with one that does.
