The most common question we get from Ipswich homeowners isn't 'how much?' — it's 'do I actually need a full replacement, or can this be repaired?' It's the right question to ask. The honest answer depends on a set of specific factors, and a roofer who always recommends replacement is not giving you the full picture.
Roof repair is the right answer when: the damage is localised, the underlying structure is sound, the tile covering has plenty of remaining life, and the cost of repair is substantially less than the cost of replacement amortised over the same period.
In practice, this covers a large proportion of the call-outs we attend in Ipswich. A handful of slipped clay tiles on a Victorian terrace off Fonnereau Road — repair. A failed lead flashing on a Rushmere St Andrew semi — repair. A section of ridge mortar failure on a Kesgrave 1985 detached — repair. These are all £150–£600 jobs on roofs that have 20+ years of life remaining.
When corroded nail fixings affect a significant proportion of a roof, piecemeal repair is rarely economic and full re-covering is the recognised remedy.BS 5534 Code of Practice for Slating and Tiling
Replacement makes sense when: the roof covering is near or past the end of its design life, when multiple systems have failed simultaneously, when the sarking">underfelt has degraded and is no longer providing secondary weatherproofing, or when the cumulative cost of repairs over the next 5 years approaches the cost of a full re-roof.
The large post-war and 1970s estates — Chantry, Whitehouse, Gainsborough, Whitton — have a concentrated replacement problem. Concrete interlocking tiles fitted between 1955 and 1985 are now 40–70 years old. The tiles themselves often look reasonable from the ground. But when we survey these roofs, we consistently find: corroded nails, failed mortar bedding on ridges and hips, and degraded underfelt that is no longer performing.
On a 1970s Chantry estate semi, a ridge repoint costs £400–£600. But if the nails are also corroded, you're looking at a tile lift-and-refix in the same season. And if the felt has gone, you're providing no secondary weatherproofing even after those repairs. At some point, the correct answer is a full re-roof — because the alternative is paying for repairs repeatedly on a system that is failing at multiple points simultaneously.
We survey Ipswich properties free of charge. We'll give you an honest assessment — and if repair is the right answer, that's what we'll recommend.
📞 Call 01473 807630A widely used rule of thumb: if more than 30% of the roof covering is damaged, compromised or at end of life, replacement is usually more cost-effective than repair. Below 30%, targeted repair extends the roof's useful life significantly for a fraction of the replacement cost.
This is a guide, not a law. A roof where 25% of tiles are failed but the remaining 75% are clay peg tiles in good condition with original hand-made character is still worth repairing and preserving. A roof where only 20% of tiles are visibly failed but the felt has gone throughout is a different case.
When a roofer surveys your property, ask them directly:
A roofer who can't or won't answer these questions hasn't surveyed the roof properly.
On some Ipswich properties — particularly those with a more complex roof profile — a partial re-roof makes sense. Re-roofing the worst-affected slope while leaving a recently replaced or better-condition slope is a legitimate approach. It's not always possible — tile matching between old and new can be difficult, and the dividing line between old and new covering needs to be properly sealed — but on the right property it saves significant money while addressing the immediate risk.
For Victorian and Edwardian properties around Christchurch Park, along Norwich Road and in the town centre streets, replacement involves different considerations. Clay peg tiles on these roofs have often been there for 80–100 years — the tiles themselves may be in far better condition than the mortar, battens and felt beneath them. In this case, a lift-and-relay operation — stripping the tiles, replacing battens and felt, and relaying the original tiles — preserves the character of the roof and may be cheaper than replacement with new clay tiles, which are expensive and hard to colour-match to weathered originals.
The repair-or-replace decision comes down to whether you're dealing with a localised problem or a whole-roof one, and the difference is usually clearer than homeowners expect once they know what to look at. A roof that's fundamentally sound but has a specific fault — a slipped tile, a failed flashing, a cracked section of ridge, a leak at one valley — is a repair, and replacing the whole roof would be waste. A roof where the problem is systemic — nail sickness slipping tiles across whole slopes, the underlying felt perished throughout, repairs needed with increasing frequency, several elements failing together — is telling you the covering has reached the end of its life, and continued repairs are money chasing a problem that will keep returning.
Age is the context that frames the decision. On the Ipswich concrete-tile estates, a roof past about forty years that's starting to shed tiles is usually near the end regardless of how it looks, because the fixings and felt beneath have aged even where the tiles haven't. A younger roof with an isolated fault almost always warrants a repair. The economics follow from this: repeated repairs on a failing roof add up, and at some point the money spent patching would have been better put toward a re-roof that resolves the cause and comes with decades of life and a fresh guarantee. Running the numbers honestly — the likely cost of the repairs you'll keep needing versus the cost of replacement — usually makes the answer clear.
There's a middle ground worth knowing about too: not every ageing roof needs full replacement immediately. Sometimes a well-chosen repair genuinely buys several more good years, and that can be the right call if a re-roof isn't affordable this year or you're planning other work. The key is honesty about which situation you're in — and that's exactly where a trustworthy roofer earns their reputation. A good one will tell you when a repair is the sensible economic choice and when it's throwing good money after bad, rather than defaulting to whichever answer suits them. On the Ipswich stock we can usually give you that honest read from the roof's age, a proper inspection inside and out, and knowledge of how your particular type of roof fails.
Nail sickness isn't visible from the ground — it requires getting onto the roof and physically testing tiles. Signs that suggest widespread nail failure include: multiple tiles slipping after a single storm event, tiles that rattle or shift when you press them from below (where accessible), and a roof over 50 years old on the original concrete tile covering. A professional survey will confirm whether nail corrosion is localised or widespread.
Yes. We provide a 5-year written guarantee on repair work and 10 years on major repair work such as full valley replacement or section re-roofing. Any reputable roofer should be able to provide a written guarantee for significant repairs.
In most cases, yes. A failing roof will be flagged by a surveyor in a mortgage valuation and either reduce the offer price or cause buyers to withdraw. A documented repair with a written guarantee removes this concern. We often carry out pre-sale roof inspections and repairs across Ipswich.
