Choosing the right roofing material for your Newmarket home is one of the most important decisions in a full roof replacement, and the options are wider than most homeowners realise.

A full roof replacement from Bury St Edmunds Roofers covers everything from stripping back the old covering and inspecting the timbers, to fitting a new breathable membrane, new battens and a new covering. The structural work is largely the same whatever you put on top. What changes the long-term performance, appearance and running cost of your roof is the material you choose for the finished surface.
This page sets out the realistic options for pitched and flat roofs, with honest notes on what each does well and where the compromises lie. There is no single right answer: the best choice depends on your property, your budget and how long you plan to stay.
Natural slate is the premium choice for pitched roofs. It is a stone product, split to consistent thickness and fixed individually to the battens below. A well-laid natural slate roof can last 80 to 100 years or more, which is why you see it on older properties that have never needed a full replacement.
Pros: Exceptional lifespan. Low maintenance over that period. Aesthetically it is hard to match, particularly on period or character properties. Genuine resale appeal. Individual slates can be replaced if one is damaged without disturbing the rest.
Cons: Higher material cost than alternatives. Heavier than many modern tiles, so the roof structure needs to be adequate to carry the load. Fixing and lap details matter: poor installation shortens the life significantly. Sourcing matching slate for future repairs can be difficult if an unusual origin is used.
Spanish and Welsh slate are both commonly used. Welsh is considered the finest but carries a significant price premium. Spanish slate is a sound, widely available alternative at a more accessible price point. We can advise on which is more appropriate for your property and budget.
Plain clay tiles are a traditional covering for pitched roofs. Each tile is small - typically around 265 mm by 165 mm - and two courses are laid for every one exposed, giving a characteristic double-lap appearance.
Pros: Excellent longevity, often 60 to 80 years on a well-built roof. Natural material that weathers to a warm, mellow tone over time. Sympathetic to older and rural properties. Individual tiles can be replaced easily.
Cons: More tiles per square metre than interlocking profiles, so higher material and labour cost. Weight is significant - the batten gauge and rafter sizing must be correct. Plain tiles require a steeper pitch than interlocking tiles, typically a minimum of 35 degrees, so they are not suitable for every roof.
Concrete interlocking tiles are the most common material on post-war housing across the country. They are cast in a range of profiles, the most widespread being the single Roman and the double Roman, and are available in a wide range of colours.
Pros: Lower cost than natural slate or plain clay. Lightweight profiles available. Consistent in size and easy to fix quickly. Many manufacturers offer long finish warranties on colour retention, though the warranty sits with the manufacturer, not the installer.
Cons: Lifespan is typically 40 to 60 years, shorter than slate or plain clay. Colour can fade or become patchy over time, particularly on south-facing slopes. Concrete tiles are heavy - much heavier than slate. Not appropriate for very low pitches. They tend to look out of place on period properties.
Concrete tiles are often the most practical choice when budget is a real constraint, particularly on standard semi-detached or detached homes built in the last 50 years.
Reconstituted or fibre cement slates are manufactured products designed to look like natural slate. They are lighter than natural slate and less expensive. Lifespan is typically quoted at 30 to 50 years, though this varies by manufacturer and product quality. They suit properties where the appearance of slate is desired but the budget or roof structure rules out the real thing. Ask about the specific product being used, as quality varies considerably between manufacturers.
Flat roofs are found on most extensions, many garages and some bungalow sections. The material options for flat roofs are distinct from pitched roof coverings.
Built-up felt (mineral felt). This is the traditional flat roof system, using layers of bitumen-based felt bonded together and finished with a mineral-surfaced cap sheet. A properly installed three-layer felt system is a sound product, though the typical lifespan is 15 to 20 years before the surface starts to crack and bubble. Cost is lower than rubber systems, which makes it attractive where budget is tight or the roof area is small.
EPDM rubber. EPDM (ethylene propylene diene monomer) is a single-ply synthetic rubber membrane that bonds fully to the deck below. It is flexible, handles thermal movement well, and resists UV degradation far better than bitumen felt. EPDM flat roofs installed correctly typically last 30 to 50 years with minimal maintenance. The material cost is higher than felt, but over the life of the roof the cost per year is considerably lower. It is the system we recommend for most flat roof replacements where the roof area justifies the upfront investment.
Whatever covering material you choose, the flashings at chimney stacks, valleys, abutments and parapet walls need to be done in lead. Substitute materials exist but lead remains the correct choice for durability and workability. Lead is soft enough to dress tightly to any surface and, when fixed correctly, has a lifespan that matches or exceeds any roofing tile. At the point of a full replacement, all lead work should be renewed rather than reused.
Modern roofing uses breathable membranes rather than the impermeable bitumen felt used on older roofs. A breathable membrane allows moisture vapour to pass through from the loft space to the outside while preventing liquid water from getting in. This significantly reduces the risk of condensation building up in the roof structure. Eaves ventilation - ensuring air can circulate freely at the lowest point of the roof - works alongside the membrane to keep the timber structure dry.
The scaffold is the expensive part of any roofing job, and it makes financial sense to carry out any additional work above the eaves while it is already in place. Fascia and soffit boards in poor condition should be replaced at this point. If gutters are cracked, loose or undersized, replacing them adds modest cost to a job that already has the access sorted. Skylights or roof windows can be installed or upgraded during the strip-out phase at lower cost than as a standalone job later.
Manufacturers of roofing tiles, slates and flat roof membranes routinely offer long product warranties - sometimes 30, 40 or even 50 years on their specific materials. These warranties cover the product itself against defect or premature failure and are issued by the manufacturer directly. They are not the same as a workmanship warranty from the installer. When you are comparing quotes, ask specifically what product is being used and what warranty that manufacturer provides, so you can look it up yourself.
