If you have slipped tiles, rattling in high winds, or rusty fixings on a roof in Milton Keynes, Newport Pagnell, Bletchley, Stony Stratford, Northampton, Bedford, or Luton, this guide explains what is happening, what to do next, and how to fix it properly. Written by Maxwells Roofing – a local, owner-led company – it covers the real-world causes of nail corrosion and loosening, the risks of leaving it, and the right way to repair and upgrade to current standards.
The Fast Answer
Tile nails rust when their protective layer fails and moisture lingers beneath the roof covering. Corrosion thins nail heads and shanks – often called nail sickness – until fixings lose strength and tiles start to creep, rattle, or slip. Even when there is little rust, older roofs may not have enough mechanical restraint for the wind loads we see today. The fix is to re-secure with stainless or copper nails and tile clips, upgrade ridges and verges to dry-fix systems where appropriate, and improve underlay support and ventilation so moisture cannot build up. The result is a safer, stronger roof that meets modern standards.
What Tile Nails and Fixings Actually Do
On a traditional tiled roof, each tile is held in place with a combination of gravity, headlap, and mechanical restraint. Nails and clips do three important jobs:
- Resist wind uplift – tiles are individually restrained or clipped so gusts cannot lift the leading edges.
- Prevent creep and rattle – proper fixings stop tiles inching out of position during thermal cycles and storms.
- Protect the roofline – correct fixing patterns at eaves, verges, ridges, and hips reduce rain ingress and debris entry.
When nails corrode or fixings loosen, the roof covering loses that mechanical strength. Small movements become slipped courses, water tracking, and ultimately leaks. That is why the quality of nails, clips, battens, and the way they are installed matters so much.
Why Tile Nails Rust
There are several corrosion drivers commonly seen on homes across Milton Keynes and the surrounding area:
- Coating breakdown on older galvanised nails – once zinc protection is scratched or sacrificed, bare steel oxidises and thins.
- Persistent moisture and condensation – lofts without effective ventilation trap damp air; droplets form on cold nail heads and attack the metal.
- Batten and timber chemistry – salts, preservatives, and tannins can accelerate corrosion where moisture is present.
- Galvanic effects – dissimilar metals near each other, combined with moisture, set up a tiny battery that eats the less noble metal.
- Pollution and freeze-thaw cycles – urban pollutants acidify surface moisture and repeated freezing expands micro cracks in coatings.
The visible clue is often a thinning or popped nail head and red-brown staining at the nail hole. In many cases the worst corrosion is hidden in the batten where the shank sits damp for long periods.
Why Fixings Loosen
Loosening can happen even where rust is limited. Typical causes include:
- Thermal movement – tiles and battens expand and contract differently. Smooth-shank nails can walk over time while annular ring-shank nails resist movement far better.
- Wind loading – modern guidance requires specific fixing patterns based on wind zone, roof pitch, and shape. Older roofs may not meet those patterns.
- Aged or sagged underlay – when felt sags between rafters, tiles are unevenly supported and can move against fixings.
- Workmanship or specification errors – nails too short, driven at an angle, wrong gauge, missing clips at eaves or verges, or mortar relied upon where mechanical fixing is needed.
Usually there is a combination – early-stage corrosion plus years of thermal cycles and wind exposure together lead to failure.
Warning Signs to Look For
- Slipped or creeping tiles – often just below ridges, along verges, or at the eaves.
- Rattling in gusts – a telltale chattering sound during windy weather.
- Rust flecks or staining – seen from the loft at nail holes or tile nibs.
- Debris in gutters – tile chips, mortar fragments, or rust flakes.
- Ceiling stains or damp insulation – small leaks that worsen in heavy rain.
- Cracked ridge or hip mortar – movement along the top lines of the roof.
- Wavy tile courses – uneven lines that hint at batten or fixing issues.
If you notice any of these, it is wise to arrange an inspection soon. Early intervention is almost always cheaper than waiting.
What Happens If You Ignore It
- Leaks and damp – water tracking beneath loosened tiles leads to stained ceilings, mould, and damaged plaster.
- Timber decay – prolonged wetting rots battens and can jeopardise rafters and structural elements.
- Insulation damage – wet insulation loses performance and can harbour mould spores.
- Storm hazards – dislodged tiles can become dangerous in high winds.
- Escalating costs – small re-fixing work can turn into large-scale strip and renewal if left too long.
Our Inspection and Compliance Process
Maxwells Roofing follows a clear, methodical survey and installation approach that suits UK homes and current standards:
- External survey – close-up checks of tile condition, nailing pattern, clips, verges, ridges, hips, and all junctions and flashings.
- Loft survey – condition of underlay, batten grading and moisture, nail heads, ventilation paths, and signs of condensation.
- Targeted fixings check – discreet sampling to confirm nail type, corrosion level, and pull-out resistance.
- Site-specific fixing design – we consider wind zone, roof pitch, and geometry to determine compliant fixings patterns.
- Building Regulations – we align work with the relevant Approved Documents:
- Part A – structure and support when coverings or fixings are changed.
- Part B – fire safety considerations at junctions and materials.
- Part C – moisture resistance and weather-tightness.
- Part F – effective ventilation to control condensation.
- Part L – opportunities to improve thermal performance during refurbishment.
- Notifications – where more than 25% of the roof covering is refurbished, Local Authority Building Control must be notified. We advise on the process and coordinate inspections so you have the correct sign-off.

Repair and Upgrade Options
Every roof is different, so we tailor solutions to the property, the exposure, and the condition we find. Common, proven options include:
1) Targeted Re-Fixing and Nail Replacement
- Remove and re-fix affected courses with A2 or A4 stainless or copper annular ring-shank nails of the correct length and diameter.
- Add compatible tile clips where wind uplift is highest – typically the eaves, verges, and around roof edges and features.
- Install eaves support trays to prevent felt sagging and protect fascias and soffits from wind-driven rain.
2) Dry Ridge, Hip, and Verge Upgrades
- Convert mortar-bedded ridges and hips to mechanically fixed, ventilated dry systems for a neat, long-lasting finish.
- Fit dry verge units to lock tile edges, tidy gable lines, and reduce maintenance.
3) Underlay and Batten Renewal – Partial or Elevation-Only
- Strip designated elevations, fit breathable underlay, and install graded, treated battens compliant with BS 5534.
- Re-lay existing tiles where serviceable and replace cracked or spalled tiles with close matches.
4) Full Re-Roof
- When fixings and battens are widely failing, we strip the covering, install new breathable underlay and BS 5534 battens, and re-tile or re-slate with the correct fixings and dry-fix accessories throughout.
- We coordinate Building Control where required and can discuss insulation upgrades while the roof is open.
Indicative Costs and Timelines
Guide figures subject to access, specification, and survey:
- Minor repair and re-fix – typically £150 – £600
- Partial strip and re-fix of one elevation – often £1,500 – £5,000
- Full tiled re-roof for a typical 3-bed – frequently £5,500 – £12,000+
Timescales range from same-day for small repairs to 2 – 7 days for larger works, weather permitting.
Materials and Methods We Use
Quality materials and the correct fixing methods make the difference between a repair that lasts and one that does not. Our standard approach includes:
- Fixings – A2 or A4 stainless steel or copper annular ring-shank nails sized for the tile and batten thickness, plus manufacturer-approved clips.
- Battens – graded and stamped BS 5534 battens, correctly spaced and securely fixed to rafters.
- Underlay – modern breathable membranes with adequate laps, drape, and eaves support trays to stop ponding in the gutter area.
- Dry-fix systems – ventilated dry ridge and hip kits, and durable dry verge units for clean lines and reduced maintenance.
- Ventilation – proper eaves and high-level ventilation to reduce condensation risk and protect metal fixings from persistent damp.
We follow the tile or slate manufacturer’s fixing guides as well as BS 5534, and we document what we install so you have a clear record of the work.
Prevention and Maintenance
- Routine checks – a visual check annually and after major storms helps catch issues before they escalate.
- Gutter care – clear gutters and outlets so water does not back up under the first course of tiles.
- Moss management – remove heavy moss growth carefully. Avoid pressure washing that can drive water under tiles and disturb fixings.
- Ventilation pathways – keep soffit vents clear and ensure insulation does not block airflow at the eaves.
- Use compatible metals – avoid mixing dissimilar metals in wet zones. Stainless or copper fixings are robust choices for long service life.
- Upgrade when convenient – if we are already repairing a section, it can be cost-effective to add dry ridge or dry verge at the same time.

FAQs
Do all tile nails eventually rust?
No. Modern stainless and copper fixings are highly resistant to corrosion. The biggest risks are older galvanised nails and any roof where moisture persists because ventilation is poor.
How do I know if I need re-fixing or a full re-roof?
If corrosion or loosening is localised, targeted re-fixing plus clips and eaves support is often sufficient. If many nails are failing and battens or underlay are degraded, partial or full renewal is usually the most economical long-term option. Our survey sets out both routes with clear costs.
Can you upgrade ridges and verges without stripping the whole roof?
Often yes. Dry ridge, hip, and dry verge systems can be installed as standalone upgrades, adding security, neatness, and ventilation without a full strip.
Will Building Control be involved?
If more than 25% of the roof covering is refurbished, Building Regulations apply. We handle notifications and coordinate inspections to ensure proper certification.
How quickly can you attend in Milton Keynes?
We aim for same-day or next-day visits for urgent issues across Milton Keynes and the surrounding towns.
What standards do you work to?
We follow BS 5534 for slating and tiling and align with the relevant Approved Documents for structure, moisture, ventilation, and thermal performance. We also follow manufacturer guidance for all systems and fixings.
