Why Material Choice Matters More Than People Realise

When homeowners in Bury St Edmunds start thinking about a new roof, the conversation often focuses on price and timing. Material choice tends to come second - but it should come first. The material you choose determines weight loading on the structure, the fixings and battens needed, the look of the finished roof, and how the roof performs over decades. Getting it right from the outset avoids expensive corrections later.

Brandon Roofers installs pitched roofs in clay tiles, concrete tiles and natural slate. Each has genuine strengths and genuine drawbacks, and we will give you an honest view of all three rather than pointing you toward whichever is easiest to fit.

Clay Tiles

Clay tiles are made from fired natural clay and, when manufactured to a good standard, can last 60 to 100 years or more. The colour is baked in rather than applied as a surface coating, so they do not fade or bleach in the way concrete tiles can.

Honest pros:

• Very long working life - clay tiles installed correctly can outlast the rest of the building
• Colour holds well over decades without significant fading
• Widely available in traditional profiles that suit older and period properties
• Good resistance to frost damage compared to some softer concrete mixes

Honest cons:

• More expensive than concrete, both for the tiles and for the additional care required in handling and fixing
• Heavier than some concrete tiles, which can matter if the roof structure is light or the timbers are marginal
• Specific profiles and colours may need to be ordered, which adds lead time to the job
• If tiles are damaged years down the line, matching originals from the same batch can be difficult

Concrete Tiles

Concrete tiles became the standard for new builds from the 1960s onwards and remain the most commonly fitted tile for pitched roof replacements in the UK. They are made from sand, cement and pigment pressed under high pressure, then cured. Modern concrete tiles are considerably better than earlier generations - the surface coatings are more durable and the mixes denser.

Honest pros:

• Lower cost than clay or slate, making them the most budget-friendly option for a full replacement
• Widely available in a range of profiles including plain, interlocking and pantile styles
• Good thermal mass helps moderate temperature in the roof space
• Replacement tiles are easy to source if individual ones need swapping out later

Honest cons:

• Surface coating can fade over 20 to 30 years, leaving tiles looking washed-out or patchy
• Heavier than clay interlocking tiles in some formats - the roof structure needs to be adequate for the load
• Porous concrete absorbs water and is more susceptible to freeze-thaw damage in hard winters compared to quality clay
• Lifespan is typically 30 to 50 years rather than the 60 or more you can expect from good clay

Natural Slate

Natural slate is the premium option for pitched roofs and is used on properties where appearance and longevity are the priority. Welsh, Spanish and Brazilian slates are all available in the UK market. Each has different characteristics in terms of thickness, density and expected lifespan, and the differences matter.

Welsh slate is regarded as the highest quality and can last well over 100 years when laid correctly, but it commands a significant price premium. Spanish slate is the most common imported option - it is less dense than Welsh, more affordable, and typically expected to last 75 to 100 years when from a reputable quarry. Brazilian slate is the most affordable of the three but is thinner and more variable in quality, and should be bought with care.

Honest pros:

• The longest working life of any pitched roof material - genuine Welsh slate can outlast two generations of homeowners
• Slim profile and natural appearance suits period and rural properties well
• Very low maintenance once correctly installed
• Does not suffer the surface fade that affects concrete

Honest cons:

• Highest material and installation cost of the three options
• Requires a roofer experienced in slate work - incorrect nail placement or wrong nail type leads to early failure
• The fixings (nails and hooks) corrode before the slates themselves wear out, so a full re-nail is eventually needed even on an otherwise sound slate roof
• Not all roof structures have the pitch angle or timber strength to take natural slate without modification

Underlay, Battens and Fixings - What Goes Beneath Matters Too

The tile or slate you choose is only part of the equation. What sits beneath it is equally important. Older bitumen roofing felt becomes brittle after 20 to 30 years and splits, allowing wind-driven water past the tile layer. Modern breathable membranes allow moisture vapour to escape from the roof space while keeping rain out - they are the correct choice for any new installation today.

Battens should be pressure-treated timber of the correct size for the tile weight and spacing. Using undersized or untreated battens to save money is a false economy - they are the first thing to rot if any moisture gets past the tile layer. Fixings (nails, hooks and clips) should be stainless steel or silicon bronze; galvanised fixings corrode faster and are not the right choice for a long-term installation.

Flashings, Ridges and Hips

Lead flashing around chimneys, at abutments and around any penetrations through the roof is replaced as standard on a new roof. The ridge and hip tiles are re-bedded in mortar or, where specified, fitted using a dry-fix ridge system. Dry-fix ridges use mechanical fixings and a ventilated system rather than mortar bedding - they do not shrink or crack over time the way mortar joints do, and they allow the roof to breathe properly. This is worth asking about when comparing quotes.

Questions to Ask Any Roofer Before You Commit

• What underlay are you specifying and why?
• Are the fixings stainless steel?
• Are you fitting a dry-fix ridge or mortar bedding?
• What is the tile weight and has the structure been assessed to carry it?
• Where does the tile or slate come from, and what is the expected lifespan?

Any experienced roofer should be able to answer all of these without hesitation. If they cannot, treat that as a warning sign.
