Why the material choice matters as much as the workmanship

A roof replacement is a long-term decision. The material you choose will be on your home for decades, so understanding the honest pros and cons of each option before you commit is worth the time. Different materials suit different roof pitches, different budgets, and different property styles. What works well on one house may be wrong for another.

At Bury St Edmunds Roofers, we cover roof replacements across Lakenheath and the surrounding villages, stripping right back to the timbers, checking the structure, fitting a new breathable membrane and fresh battens, then re-covering in whichever material makes most sense for your home.

Natural slate

Natural slate is the traditional choice for pitched roofs across Britain and, when it comes from a reliable quarry, it is one of the longest-lasting materials available. Welsh slate in particular has a strong record, with well-maintained examples still in service after well over a century.

Pros:

• Exceptional lifespan when quality slate is used and correctly fixed
• Visually distinctive - the depth and variation of colour is difficult to replicate artificially
• Low maintenance once bedded correctly with proper lead flashings
• Adds to the character of older properties

Cons:

• Higher material cost than concrete or fibre cement alternatives
• Heavier than most alternatives, which can matter if the roof structure has weakened
• Requires a minimum roof pitch - usually around 25 to 30 degrees depending on the slate size
• Sourcing matching slates for future repairs can be difficult if the original batch is exhausted

Natural slate is best suited to properties where the roof pitch is steep enough to shed water quickly, and where the visual quality of the finish justifies the additional upfront cost. Reclaimed slate is sometimes available and can work well, but the quality varies considerably, so it is worth checking that any reclaimed material has been properly graded before agreeing to use it.

Concrete plain tiles

Concrete plain tiles are a common choice for many residential roofs and are widely used on replacement jobs. A good concrete plain tile pitched correctly sheds water reliably and sits well on roofs with pitches from around 35 degrees upward.

Pros:

• Significantly lower material cost than natural slate
• Available in a wide range of colours and finishes, including options that mimic plain clay tiles
• Good availability of matching replacements if individual tiles need changing in the future
• Consistent sizing makes fixing and pointing more straightforward

Cons:

• Heavier than interlocking tiles of a similar size, so structural load should be checked
• Concrete can fade over time, and tiles installed in the same batch may not match perfectly with later additions
• Require regular moss and algae treatment on north-facing pitches as the surface becomes more porous with age
• Do not carry the same visual appeal as natural slate or handmade clay

Concrete interlocking tiles

Interlocking tiles - whether double roman, single roman or plain - cover more roof area per tile than plain tiles. This makes them faster to install and slightly lighter in overall weight. They are widely used on 1970s and 1980s-era housing stock, which is now at the age where replacement becomes relevant.

Pros:

• Lower labour cost due to faster installation
• Lighter load per square metre than plain tiles
• Can be used on lower pitches than plain tiles in some configurations
• Good value for a straightforward replacement job

Cons:

• More visually utilitarian than plain tiles or slate
• The interlocking profile can allow wind-driven rain to penetrate more readily at lower pitches if the underlay below is not in good order
• Concrete fading applies here too, and colour-matching after several years is harder

Fibre cement slates

Fibre cement slates are a man-made alternative to natural slate that can be used on roof pitches from around 15 to 20 degrees in some products. They are used widely on lower-pitched roofs where natural slate would not drain effectively, and they carry a much lower price point than Welsh slate.

Pros:

• Lower cost than natural slate, often significantly so
• Lightweight, which reduces load on older roof structures
• Can be used on pitches too shallow for natural slate
• Available in a range of colours

Cons:

• Do not have the depth of colour and texture of natural slate
• Manufacturer product lines change, which can make matching slates for future repairs difficult
• Lifespan varies considerably by product and brand - the manufacturer's own data is the most reliable guide
• Some fibre cement products are more brittle and can crack if walked on during maintenance

Fibre cement slates are a practical, cost-effective choice on the right roof. They are not a substitute for natural slate aesthetically, but where budget is a constraint or pitch is the limiting factor, they do the job well.

Clay plain tiles

Handmade or machine-made clay plain tiles are a traditional material for many older properties. They have a warmth to the colour that concrete cannot fully replicate, and they sit well on older-style houses. However, they are at the higher end of the cost range.

Pros:

• Excellent longevity - clay tiles installed correctly can outlast concrete equivalents by decades
• The colour is baked in rather than applied as a surface finish, so fading is minimal
• A visually sympathetic choice for older and period properties

Cons:

• Higher material cost, sometimes approaching natural slate
• Handmade clay tiles vary slightly in size, which makes fixing more skilled work
• Heavy, so the roof structure needs to be able to carry the load

Flat roofs: felt and EPDM

Where a property has a flat or very low-pitched roof - common on extensions, garages and rear additions - the options are different. Two systems worth knowing about are built-up felt and EPDM rubber membrane.

Built-up felt has been the standard flat roofing system for decades. Modern high-performance felt uses a torch-on application rather than cold pour, which bonds far better and lasts significantly longer than older felt systems. The main limitation is that felt can still degrade over time, particularly where it is exposed to ponding water or UV without a protective finish.

EPDM rubber membrane is now widely used as an alternative on flat roofs. It is a single-ply membrane that is bonded across the whole surface, which eliminates the seams that are the most common failure point on built-up felt. EPDM is flexible, which means it handles building movement well. It is typically specified with a lifespan of several decades by manufacturers, though actual performance depends on how it was installed and how it drains. EPDM costs more to install than basic felt but less than some of the premium alternatives.

For any flat roof, the most important question is drainage. A flat roof that holds water will fail faster regardless of the membrane. The design of the falls and the positioning of outlets matters as much as the material choice.

Gutters, fascias and lead work

A roof replacement is the right time to look at gutters, fascias and soffits. These are most accessible when scaffolding is already erected and the old covering is off. Replacing worn or cracked guttering at this stage costs far less than a separate scaffold visit later. Lead flashings around chimneys, skylights and valleys should be replaced or re-dressed as part of any full roof replacement, since they are as important to the waterproofing as the tiles themselves.

Questions to ask about materials

• What is the minimum pitch for the tile or slate being recommended, and does my roof meet it?
• What is the manufacturer's stated expected lifespan for this product?
• Is the material widely available so that individual tiles can be matched in future repairs?
• What is the weight per square metre, and has the roof structure been checked to carry it?
• Is the colour a surface coating or baked in?
