Choosing the right roofing materials for your Poringland home is one of the most important decisions in a re-roof project - get it right and the roof will serve you well for decades.
When the time comes for a new roof, the specification you agree at the start determines how long the roof lasts, how much maintenance it needs, and whether it suits your property visually and structurally. There is no single material that is right for every house, and an honest assessment of the options helps you make a decision you will not regret.
This page runs through the main materials used on pitched and flat roofs for residential properties, with a straightforward look at what each one does well and where it falls short. The aim is to give you enough information to have a proper conversation with any roofer you approach, rather than taking a specification on trust.
Clay tiles weather well, hold their colour naturally over time, and have an expected service life measured in generations rather than decades. A well-fired clay tile on sound battens and a modern breathable underlay can reasonably be expected to outlast the timbers beneath it.
Pros: Excellent longevity. Natural appearance that suits traditional properties. Do not fade or discolour significantly. Frost-resistant grades are available for exposed positions.
Cons: Heavier than concrete alternatives, so the roof structure must be capable of carrying the load. More expensive than concrete tiles to buy. Not always appropriate for very shallow pitches. Some profiles are not suitable for pitches below 35 degrees.
Clay tiles are the material of choice for period properties and for any home where planning or conservation considerations apply. If you are re-roofing a house that originally had clay, matching the tile profile and colour correctly is important - a close but imperfect match can be visually jarring and may affect the value of the property.
Concrete interlocking tiles are the most widely used roofing material on homes built from the 1960s onwards. They are robust, readily available in a wide range of profiles, and significantly cheaper than clay. The key limitation is their colour: concrete tiles are pigmented during manufacture, and that colour fades and can mottle over time as the surface cement weathers.
Pros: Lower cost than clay. Wide choice of profiles including interlocking single camber, double roman, and large format slates. Generally lighter per unit than plain clay tiles. Suitable for pitches from around 17.5 degrees depending on profile.
Cons: Surface colour fades over 15-25 years, often unevenly. Heavier per square metre than natural slate. Some older profiles can be difficult to match if partial repairs are needed in future. The surface can harbour moss and lichen more readily than smooth-faced materials.
Concrete tiles are a sensible choice where budget is the primary consideration and the property is not subject to planning restrictions. On a straightforward semi-detached or detached house in Poringland where appearance is a secondary concern to cost-effectiveness, a quality concrete interlocking tile on a breathable underlay is a practical specification.
Natural slate is the premium option for pitched roofing. Welsh and Spanish slates are the most commonly available, with Welsh slate generally considered the superior material for hardness and longevity. A slate roof installed correctly on sound timbers, with proper head and side laps maintained, can last 80 to 100 years or more.
Pros: Outstanding lifespan. Slim profile that gives a clean, low-profile appearance. Holds colour well. Suits both period and contemporary properties. Low maintenance once properly bedded and fixed.
Cons: The most expensive roofing material. Requires careful fixing - slates are nailed individually, and incorrect nailing leads to slippage. Not every roofer has the skill to lay slate properly. Heavier than most concrete tiles, though lighter than clay plain tiles. Salvaged or reclaimed slates vary widely in quality and remaining life.
If you are considering natural slate, ask specifically about the origin and grade of slate being proposed. Spanish slate is perfectly serviceable, but varies in quality between suppliers. Welsh blue-grey slate from quarries in Gwynedd is generally regarded as the benchmark.
Fibre cement slates are a manufactured alternative to natural slate. They are lighter, more uniform in size, and less expensive. Modern fibre cement slates have improved considerably over the asbestos-cement products they replaced, and they carry a more predictable colour and texture than natural stone.
Pros: Significantly cheaper than natural slate. Uniform sizing makes laying straightforward and reduces tile waste. Lighter weight reduces structural loading. Available in a range of colours.
Cons: Do not have the same lifespan as natural slate - typically 30-40 years. The appearance is noticeably more uniform and lacks the natural variation of real slate, which some homeowners find less attractive. Some earlier products were prone to delamination, though current products have improved. Planning authorities in conservation areas will usually insist on natural slate.
For extensions, garages and bay roofs, the flat roof system specified has a significant bearing on how long it lasts and what maintenance it needs. EPDM (ethylene propylene diene monomer) rubber membrane has become a widely favoured option for residential flat roofs because of its durability and flexibility.
EPDM is a single-ply membrane supplied in large sheets, which reduces the number of seams and therefore the number of potential weak points. It stays flexible in cold weather and does not become brittle with age in the way that older bitumen felt products did. New EPDM flat roofs typically cost in the range of £80-£120 per square metre installed, depending on the area and complexity.
Pros: Long expected service life - a properly installed EPDM roof on a sound deck can be expected to remain watertight for 25 years or more. Resistant to ultraviolet degradation. Minimal maintenance required once installed. Relatively lightweight.
Cons: Not the cheapest option upfront compared with felt. Needs correct bonding to the deck - a poorly bonded membrane can lift or blister. Repairs require EPDM-specific adhesive and patches; it cannot be overfelt in the way bitumen products can.
Torch-on felt uses layers of polymer-modified bitumen sheet, fused to the deck and to each other using a gas torch. It is a well-established system that has been used successfully on both residential and commercial buildings for many years. The quality of a felt flat roof depends heavily on how many layers are used and how carefully the details are done at edges, upstands and outlets.
Pros: Lower initial cost than EPDM. Widely understood system with a long track record. Can be overlaid with a further layer if surface weathering occurs before structural failure. Mineral-faced top sheets provide good surface protection.
Cons: Shorter lifespan than EPDM if only a single layer is used - a two-layer system is the minimum for a durable result. Bitumen can become brittle in sustained cold conditions and soften in exceptional heat. Joints and laps are the most common point of failure.
For a straightforward garage or small extension roof where budget is tight, a two-layer torch-on felt system on new or sound decking is a practical choice. For larger or more complex flat areas where long-term performance is the priority, EPDM offers a more durable result.
Regardless of the material chosen, a properly specified new roof includes several elements that are sometimes treated as optional but are not:
If a quote does not specify these items, ask about each one directly. The difference in cost between a properly detailed roof and a cut-price job is often small at the time but significant over the life of the covering.
Every roof is different, and the right material for your home depends on its age, structure, pitch, planning status and budget. Call Norwich Roofers to arrange a survey and discuss which specification makes the most sense for your property before any work begins.
