Lewisham has a genuinely rich stock of Victorian and Edwardian housing, particularly through Blackheath, Brockley and Ladywell, where many streets of terraced houses still carry their original slate roofs. When the time comes for a repair or replacement, the material you choose matters both for how the property looks and how well it performs for decades to come.
Natural Slate: The Traditional Choice
Most of Lewisham’s original Victorian roofing was natural slate, and it’s usually the right choice when repairing or replacing a roof on a period property. Slate is exceptionally durable — a well-maintained slate roof can last well over 100 years — and it keeps a property’s character intact in a way that alternative materials sometimes can’t. It costs more upfront than concrete tile, but the longevity and the way it suits period properties around Blackheath and Brockley usually justifies the investment. See our new roof installations service for full replacements, or tile replacement for smaller repairs.
Concrete and Clay Tiles: The Practical Alternative
Concrete tiles are the most common modern alternative — cost-effective, widely available, and suitable for most property types. Clay tiles sit between concrete and slate in both cost and character, and can be a good match for some Edwardian properties that originally used clay rather than slate. Both are worth considering where matching original slate isn’t essential or budget is more of a constraint.
Matching Existing Roofs
If you’re only replacing a section of roof — after storm damage, for example — matching the existing material and profile matters more than starting from scratch. A patch of mismatched tiles stands out immediately on a period terrace, whereas a properly matched repair is barely noticeable. This is one of the reasons it’s worth using a roofer experienced with Lewisham’s specific mix of period roofing rather than a generic supplier.
Flat Roofing for Extensions
Many Victorian and Edwardian properties across Lewisham have had rear extensions added over the decades, almost always with a flat roof section. Here the material choice is different — EPDM rubber, GRP fibreglass or felt rather than tile or slate — see our flat roofing service for how these compare.
Lead Flashing and Detailing
Whatever the main roofing material, the flashing around chimneys, valleys and abutments is almost always lead on period properties, and it’s worth maintaining this properly rather than substituting cheaper alternatives that won’t last as long or look right on an older building. See our chimney repairs service.
Cost vs Longevity
It’s tempting to focus purely on upfront cost, but roofing materials should really be judged on lifetime cost — a slate roof costing more initially but lasting a century works out considerably cheaper per year than a lower-cost material needing replacement every 30-40 years. For a property you plan to keep long-term, it’s worth weighing this properly rather than defaulting to the cheapest option.
Conservation Considerations
Some parts of Lewisham fall within conservation areas, which can affect what roofing materials are permitted on a visible roof slope. It’s always worth checking with the council before committing to a material change, particularly on a period property in areas like Blackheath.
Getting Expert Guidance
Choosing the right roofing material is easier with a proper assessment of your existing roof and property. A roof inspection gives you a clear picture of what you’re working with and honest guidance on the best material for your specific property and budget.
