Dry Ridge Systems – A Stronger, Safer, Maintenance-Free Upgrade for Your Roof

Forget traditional mortar. Modern roofs deserve modern protection — and that’s where dry ridge systems come in.
While sand-and-cement mortar was once the standard method for fixing ridge tiles, it is no longer considered the safest or most reliable option. Since the introduction of BS 5534, dry ridge systems are now required on all new roof installations (though not on repairs to existing roofs).

At BrightonRoofers, we install high-quality dry ridge systems across Brighton, Hove, Worthing, Shoreham, Lewes and throughout East & West Sussex. Whether you’re replacing an old mortar ridge or upgrading your roof for safety, ventilation, and long-term performance, our experienced team is here to help.

With decades of roofing expertise, we provide reliable, compliant, professionally installed dry ridge systems designed to protect your home for years to come.

Dry Ridge System Checklist

Considering upgrading your roof? Ask yourself:

  • When was your roof installed?
    Older mortar systems may now be unsafe or deteriorating.

  • Have you noticed loose or slipping ridge tiles?
    Mortar breaks down over time, putting tiles at risk.

  • Does your roof suffer with condensation or lack ventilation?
    Dry ridge systems allow controlled airflow.

  • Are you spending time or money on ongoing ridge repairs?
    A dry ridge system eliminates mortar maintenance completely.

If you’re unsure whether a dry ridge system is right for you, we offer free roof inspections across Sussex.

A dry ridge system uses mechanical fixings instead of mortar to secure ridge tiles or hip ridge tiles to your roof. This method offers:

  • Greater strength

  • Long-term durability

  • Built-in ventilation

  • Flexibility for natural roof movement

Unlike mortar, a dry ridge system does not crack, crumble, or fail due to weather, thermal expansion, or vibration from nearby traffic or rail lines.

Because the system is mechanically fixed, ridge tiles are locked firmly into place, drastically reducing the risk of movement or tile loss during storms.

1. Built-In Ventilation

A dry ridge system allows controlled airflow along the ridge line, reducing condensation inside your loft and improving overall roof health.

2. Safe During Roof Movement

Roofs naturally expand, contract and flex. Mortar cracks — dry ridge systems adapt.

3. Maintenance-Free

No more repointing, patching or replacing crumbling mortar.

4. Stronger and Storm-Safe

Mechanically fixed ridge tiles are far less likely to blow off during strong coastal winds — especially important in Sussex.

5. Compliant With UK Building Standards

Required by law for new-build roofs under BS 5534.

Dry ridge systems are ideal for:

  • New-build properties (mandatory under current standards)

  • Roof replacements

  • Upgrading older mortar ridge lines

  • Improving safety on weather-exposed roofs

  • Reducing condensation in poorly ventilated roofs

If your ridge tiles are loose, cracked or repeatedly repaired, a dry ridge upgrade is a smart, long-term investment.

  • We provide honest advice and free inspections

  • We specialise in both tiled and slate pitched roofs

What is a dry ridge system?

A dry ridge system is a modern roofing method that secures ridge tiles using mechanical fixings instead of mortar. It provides better strength, ventilation and long-term durability.

Are dry ridge systems better than mortar?

Yes. Dry ridge systems are stronger, longer-lasting, maintenance-free, and far less likely to fail during storms or roof movement. Mortar cracks over time—dry ridge does not.

Are dry ridge systems required by UK building regulations?

For new roofs, yes. Under BS 5534, all new-build roofs must use a dry ridge system. Mortar is still allowed for repairs on existing roofs.

Do dry ridge systems help with condensation?

Absolutely. A dry ridge system allows controlled ventilation along the ridge line, which reduces moisture build-up and helps prevent condensation inside the loft.

How long does a dry ridge system last?

Most dry ridge systems last 30–50 years with minimal maintenance, depending on installation quality and the type of roof tiles used.

Will ridge tiles blow off in strong winds?

Mechanically fixed ridge systems are much safer than mortar. When installed correctly, the tiles are locked in place and highly resistant to wind uplift.

Can I convert my old mortar ridge to a dry ridge system?

Yes. Dry ridge systems can be retrofitted onto most existing roofs, providing an immediate upgrade in safety, stability and ventilation.

How much does a dry ridge system cost?

Costs vary depending on roof size, tile type and access, but dry ridge installations are typically more cost-effective long-term due to being maintenance-free.

How long does installation take?

Most homes take 1–2 days for a complete dry ridge installation, depending on the ridge length and roof condition.

Is a dry ridge system suitable for all roof types?

Yes. Dry ridge systems can be used on: Tiled roofs Slate roofs New builds Older properties Hipped roofs

Do you offer free inspections?

Yes. BrightonRoofers provides free roof assessments and quotes for homes across East and West Sussex.
