6 minWhen roof tiles need replacing, finding matches for your existing roof is often the biggest challenge. Roofing materials change over decades - manufacturers discontinue profiles, colours shift, and what seemed a standard tile in 1985 may be unavailable today.
This guide explains how to identify and source matching tiles, strategies when exact matches aren't available, and practical approaches to tile replacement.
Identifying Your Existing Tiles
Before sourcing replacements, you need to know what you have. Key identification factors include:
Material: Clay, concrete, or slate? The texture, weight, and sound when tapped helps distinguish. Clay is smooth and rings when struck; concrete is rougher and makes a duller sound.
Profile: Plain flat tiles, interlocking profiles, pantiles, or something else? Interlocking tiles have specific shapes that must match exactly; plain tiles are more forgiving.
Size: Measure precisely. Even small dimensional differences prevent proper fitting with interlocking tiles.
Manufacturer and name: Many tiles have manufacturer stamps on the back. This information greatly simplifies sourcing. Check any spare tiles you might have in the garage or loft.
Colour and finish: Note the colour, surface texture, and any coating. Tiles weathered for 30 years look different from new tiles of the same type.
Sourcing Current Production Tiles
Many tile profiles remain in production for decades. Long-established products like Marley Modern, Redland 49, and various plain tile patterns remain available new. If your tiles are current production:
Standard builders' merchants stock common tiles. Specialist roofing merchants have wider ranges. Manufacturers can confirm current availability for specific products.
New tiles won't match weathered existing tiles immediately - they'll be cleaner, brighter, and more uniform. Colour difference is most obvious initially but reduces over time as new tiles weather.
Discontinued Tiles
When your tiles are no longer manufactured, options include:
Reclaimed tiles: Salvage yards and specialist reclaimed tile merchants stock tiles from demolished buildings. These match aged appearance better than new alternatives and may be your only option for exact matching.
Successor products: Manufacturers sometimes replace discontinued products with compatible alternatives. The new product may fit existing tile courses even if not identical.
Close alternatives: Another manufacturer's similar profile might be close enough for less visible areas of the roof.
Recycling within the roof: Move existing tiles from less visible positions (rear slopes, behind parapets) to prominent areas, using new/alternative tiles in the hidden positions.
Reclaimed Tile Considerations
Reclaimed tiles offer excellent matching but require careful selection:
Condition assessment: Check for cracks, delamination, frost damage, and excessive wear. Not all reclaimed tiles are usable - reject poor quality even if the profile matches.
Sufficient quantity: Buy more than you need - a proportion may prove unsuitable on closer inspection, and having spares for future repairs is valuable.
Consistency: Tiles from different demolitions may vary. Try to source from a single batch where possible.
Age appropriateness: Reclaimed tiles with remaining life comparable to your existing roof make sense. Very old reclaimed tiles on a relatively young roof may fail before surrounding tiles, requiring repeated repairs.
Strategies for Visible Repairs
When perfect matching isn't possible, placement strategy minimises visual impact:
Less visible positions: Use non-matching tiles on rear slopes, behind chimneys, under overhanging trees - anywhere that's not prominent. Save matching tiles for visible front elevations.
Disperse rather than concentrate: A scattering of slightly different tiles across a slope is less obvious than a concentrated patch of mismatched tiles.
Complete sections: Where extensive replacement is needed, consider replacing complete roof sections (one slope, or eaves to ridge) with consistent materials rather than patching.
Accept weathering: New tiles that don't quite match will blend better after a year or two of weathering. What looks obvious immediately after repair often becomes acceptable with time.
Special Tiles
Roofs typically need more than just standard field tiles:
Ridge and hip tiles: These are often easier to match than main tiles, as they're not interlocking and standard profiles suit many situations. See our ridge tile guide.
Eaves tiles: Some profiles use specific shorter tiles at the eaves. These may be harder to source for discontinued products.
Valley tiles: Purpose-made valley tiles for some profiles. Lead valleys provide an alternative that works with any tile type.
Verge tiles: Edge tiles on gable ends. Again, may need specific products or alternative solutions like dry verge systems.
When to Consider Full Re-Roofing
If significant areas need replacement and matching proves impossible or uneconomic, complete re-roofing might make sense:
Patching an old roof with poorly matching tiles rarely gives satisfactory appearance. The cost of sourcing scarce reclaimed tiles plus multiple repair visits can approach re-roofing costs. If the existing tiles are generally at end of life, comprehensive replacement provides better value than repeated repairs.
Re-roofing allows choice of current-production tiles ensuring future repair simplicity, plus opportunity to address any underlying structural issues, improve insulation, and provide a roof covering with decades of remaining life.
Cost Factors
Tile replacement costs vary enormously based on tile availability:
Common current-production tiles: £1-3 per tile. Reclaimed tiles: £2-5 per tile depending on type and scarcity. Rare or specialist tiles: Prices vary widely; some discontinued tiles command significant premiums.
Labour for tile replacement depends on access requirements, quantity, and complexity. A few accessible tiles might cost £100-200 to replace. Extensive work requiring scaffold costs proportionally more.
Building a Tile Stock
If you own a property with unusual or discontinued tiles, building a stock of spares is worthwhile:
When reclaimed tiles matching yours appear, buy what you can reasonably store - even if you don't need them immediately. When any roof work is done, salvage any usable removed tiles. Ask your roofer to watch for matching tiles on other jobs.
A stock of 20-30 spare tiles provides for years of minor repairs without sourcing difficulties.
