Slate Roof Repairs Brighton
Original slate re-bedded, replaced, or carefully saved wherever possible — common across Brighton's period terraces where the roof is older than it looks.
Why Slate Roofs in Brighton Need a Different Approach
A large share of Brighton & Hove's housing stock — particularly the Victorian and Regency terraces across Hanover, Seven Dials, Kemptown, and North Laine — was originally roofed in natural slate, much of it Welsh slate that's now well over a century old.
Natural slate is a genuinely excellent material, with a service life that can stretch to 75–150 years depending on the type and how exposed the property is. But when a slate roof this age starts failing, the cause usually isn't the slate itself.
Nail sickness is the most common — and most commonly missed — cause of slate roof failure on older Brighton properties. Slates are held on by nails driven through the top of each tile into the batten beneath. Over decades, those nails — especially the older iron or steel ones common on Victorian roofs — corrode and weaken.
Once a nail fails, the slate below it is no longer secured, and it slips, even though the slate itself might be in perfectly good condition. This is why a slate roof can look intact from the ground while individual slates are quietly working loose underneath, and why a proper survey checks fixings, not just the visible slate surface.
What Brighton Homeowners Say About Us
Real feedback from real jobs — roof repairs, replacements and flat roofing across Brighton & Hove.
Repair, Partial Re-Slate, or Full Replacement?
Not every slate roof problem calls for the same solution:
- Individual repair is right when the problem is a handful of isolated slipped or cracked slates and the surrounding roof and fixings are still sound.
- Partial re-slating — stripping and redoing a specific section — makes sense when nail sickness or slate failure is concentrated in one area, such as a south or west-facing slope that's taken more weathering than the rest of the roof.
- Full replacement is the better long-term option when nail sickness is widespread across the roof, since re-fixing individual slates on failing battens is a losing battle — once fixings start going, more follow, and repeated one-off repairs end up costing more over a few years than a proper re-slate would have.
A proper survey should tell you honestly which category your roof falls into — not just recommend a full replacement by default because it's the bigger job.

Our Slate Roof Repair Services
Individual slate replacement — removing damaged, slipped, or cracked slates and replacing them with matching salvaged or reclaimed slate wherever possible, so the repair doesn't stand out against the surrounding roof. A mismatched replacement slate is one of the most common giveaways of a rushed repair job.
Re-fixing loose slates — where slates have slipped due to nail sickness rather than damage to the slate itself, re-securing them properly rather than just nailing back into the same failing fixing point.
Ridge and hip repairs — repointing or re-bedding ridge and hip tiles where the mortar has failed, a common issue on roofs that have had well over a century for the original bedding to degrade.
Valley repairs — repairing or replacing lead or fibreglass valley linings where slate roofs meet at an angle, a common failure point where water volume is concentrated.
Sourcing matched slate — for repairs on period properties, sourcing slate that matches the existing roof in size, colour, and texture, so repairs are close to invisible rather than an obvious patch.

Slate Roof Repair FAQ's
My slate roof looks fine from the ground — why would I need it checked?
Nail sickness is invisible from ground level. The slates themselves can look intact while the fixings holding them in place have corroded, which is exactly why a proper roof-level inspection matters more on an older slate roof than a quick look from the pavement.
Can you match new slate to my existing roof?
Yes — sourcing slate that matches in size, colour, and texture is standard practice for repairs on period properties, and reclaimed slate is often the best match for an older roof.
How long does natural slate actually last?
Genuinely well-maintained natural slate can last 75–150 years depending on the type and exposure. In practice, though, it's very often the fixings — not the slate — that fail first, particularly on roofs over 60–80 years old.
Do I need permission to repair or replace slate on a listed or conservation area property?
Often yes for anything visible from the street, particularly for full or partial re-slating. This gets checked as part of the survey.
Is composite slate a good alternative to natural slate?
It can be, particularly where budget or a lack of conservation constraint make it practical — but it won't match natural slate's exceptional lifespan.
