If your Ipswich home was built between 1950 and 1985 and has a concrete interlocking tile roof, nail sickness is something you should know about. It's the most common structural roofing issue we diagnose on the large post-war estates — Chantry, Whitehouse, Gainsborough, Whitton — and understanding it can save you a significant amount of money and stress.
Nail sickness is the term used when the nails fixing roof tiles to the battens have corroded to the point where they no longer hold the tiles securely. On the post-war and 1960s–70s estates built across Ipswich, tiles were fixed with mild steel nails that have, over 40–70 years, rusted through. The result is a roof where the tiles are held in place largely by their own weight — and, in some cases, by the remaining mortar bedding on ridge and hip tiles that has also degraded.
A nail-sick roof looks normal from the ground. Tiles sit in position. The roof appears weathertight. But in a storm with sustained wind speeds above 30–40mph — entirely normal in a Suffolk winter — the tiles can lift, shift and slide out of position. We see this pattern across Ipswich's estates every time there's a significant storm event.
Where more than a small proportion of nail fixings have corroded, industry guidance recommends stripping and re-covering rather than piecemeal repair, as re-nailing individual tiles is rarely durable.BS 5534 Code of Practice for Slating and Tiling
You can't diagnose nail sickness from the ground — it requires getting onto the roof and physically testing individual tiles. However, the following are strong indicators that warrant a survey:
The definitive solution. Strip all tiles, replace battens and felt, install modern breathable membrane, refix all tiles with stainless ring-shank nails. The roof is restored to a secure, weathertight state with modern materials and a 40–50 year lifespan ahead of it. This is the right answer on properties where widespread nail failure is confirmed.
An intermediate option: tiles are lifted section by section and re-fixed with stainless nails, without replacing the underfelt. Less disruptive and less expensive than a full re-roof, but appropriate only when the tiles and felt are in reasonable condition and nail corrosion is the primary problem. We carry out lift-and-re-nail operations where the survey supports it.
We carry out free roof surveys across Ipswich's post-war estates. We'll confirm whether nail sickness is present and give you honest options and pricing.

But the more insidious risk is slower: tiles that shift slightly allow water to track under the edge in heavy rain, gradually saturating the degraded underfelt and the timbers beneath. By the time water appears inside the property, significant timber damage can already have occurred.
A survey costs nothing and takes an hour. Knowing your roof's condition is far cheaper than discovering it through a ceiling collapse.
The Chantry and Whitehouse estates in south-west Ipswich were among the largest public housing developments in Suffolk, built predominantly in the late 1950s through the 1970s. The concrete interlocking tiles fitted during this period are now 50–70 years old. We carry out more nail-sickness diagnoses on these two estates than anywhere else in our coverage area.
The good news: these roofs have simple profiles — standard gable-end and hipped pitches with minimal complexity. A full re-roof on a Chantry estate semi is a straightforward job and is at the lower end of the re-roofing price range as a result. The tiles may be old, but the roofs underneath are simple and economic to work on.
Very common on properties built between 1950 and 1985. Our survey data suggests that the majority of concrete tile roofs in Ipswich of this age have some degree of nail corrosion. The question is whether it's localised or widespread, which determines whether repair or replacement is the right response.
A nail-sick roof that is in a known deteriorated state could potentially affect an insurance claim for storm damage if an insurer argues the roof was in poor condition before the loss event. There's no standard industry position on this, but it's a reason to address known nail sickness rather than leaving it.
A lift-and-re-nail on a 3-bed semi in Ipswich typically costs £1,500–£3,000 depending on scope. A full re-roof addressing nail sickness and all associated issues costs £5,000–£9,000. We give you exact figures after a free survey.
