Yellow, Orange or Red Wind Warning? What Each One Means for Your Roof (Dublin and Wicklow)

From now until spring, weather warnings become part of the weekly forecast. Most homeowners know the colours, but fewer know what a Status Yellow, Orange or Red wind warning actually means in numbers, or what it should change about how they look after the house.

This guide explains the three levels using Met Éireann's own definitions, then sets out what we suggest doing for your roof, gutters and chimney at each stage. Everything here can be done from the ground or from indoors.

What the three colours mean

Met Éireann publishes its criteria on its weather warnings explained page. For wind over land, the guideline figures are:

Two points from the same page are worth knowing:

• The numbers are guidelines, not hard lines. Met Éireann describes its warnings as impact-based. The effect of the wind depends on location, recent weather, the state of the ground, the time of year and how long the event lasts, so a warning can be issued at a higher level than the raw figures suggest.
• A storm does not need a name to do damage. A storm is named when Orange level wind warnings are forecast to affect a wide area over land, but Met Éireann notes that Orange or Red level gusts can occur in exposed areas without the event being named.

Rain warnings use the same colours. A Status Yellow rain warning, for example, starts at 20 to 30 mm in six hours or less, and Met Éireann says amounts can be up to double on windward upper slopes. That matters for homes on higher ground in Wicklow and along the Dublin Mountains.

How much notice you get

According to Met Éireann, warnings are generally not issued more than 60 hours ahead of the expected weather. Weather advisories can come earlier, up to about a week ahead, and normally flag weather that may reach Orange or Red criteria.

In practice, an advisory is your cue to do the unhurried jobs: look over the roof from the garden, clear what you can reach at ground level, and book a roofer if something already looks loose. Once the warning itself is issued, the window for getting repairs done before the wind arrives is usually short.

Status Yellow: a test for weak points

Yellow wind warnings are common in an Irish winter. A roof in good condition should cope without trouble. What a Yellow warning tends to do is find the parts that were already failing:

• slates or tiles that had slipped or cracked
• ridge and hip tiles sitting on tired mortar
• loose flashing around chimneys and roof windows
• gutters with broken brackets or open joints
• felt on older garage and shed roofs that has started to lift at the edges

What to do: walk around the house and look up from the ground, using binoculars or your phone camera zoom if you have them. Bring in or tie down bins, garden furniture and trampolines, since these do as much damage to gutters, roof windows and conservatory roofs as the wind does. If your roof makes new sounds as the wind picks up, our guide to roof noise in wind explains which ones matter.

If you regularly lose a slate or a ridge tile in Yellow level winds, that is a sign of an underlying problem such as nail sickness or failed bedding, not bad luck.

Status Orange: expect some damage in the area

Met Éireann describes Orange conditions as infrequent and dangerous, with a possible threat to life and property, and advises people to prepare in a way that suits their location and activity.

At these gust speeds we expect calls from across Dublin and Wicklow: lifted ridge tiles, slates stripped from exposed corners and verges, fascia and soffit boards pulled loose, fallen aerials and branches on roofs.

Before it arrives:

• Finish the Yellow checklist above.
• Move cars away from gable ends, chimneys, large trees and old boundary walls.
• Take dated photos of each side of the roof from the ground. If you need to claim later, a "before" record helps. See our storm damage insurance claim checklist.
• Check the attic hatch is closed properly and that you know where buckets, towels and a torch are.

During it: stay indoors. Do not go outside to look at the roof or to pick up fallen slates, as more may follow.

Status Red: protect people, not the roof

A Red warning is rare. Met Éireann's advice at this level is to take action to protect yourself and your property and to follow the instructions of the authorities. The Office of Emergency Planning's storm guidance is direct: shelter in place during red warnings, stay inside and keep away from windows in case of flying debris, and avoid going near trees, walls or power lines.

For your roof, that means all preparation must be finished before the warning takes effect. Nothing on a roof is worth going outside for during a Red warning. No reputable roofer will work at height in those conditions either, so if a contractor offers to go up mid-storm, treat that as a warning sign about the contractor.

If part of the roof is damaged while the storm is still blowing:

• Move everyone out of the rooms directly below the damage.
• Catch water in buckets and move furniture and electrics out of the way.
• If water is coming through near a light fitting, switch that circuit off at the fuse board if it is safe to reach.
• Wait for the warning to pass before anyone inspects the outside.

After the wind drops

Once the warning has expired and it is daylight:

1. Look for hazards first. The gov.ie storm guidance says that if you see a fallen electricity wire, do not approach or touch it, and call ESB Networks on 1800 372 999, or the emergency services on 112 or 999.
2. Walk the boundary and look up. Check for missing or displaced slates and tiles, gaps along the ridge, flashing that has lifted, gutters hanging out of line, and debris on flat roofs.
3. Check the ground. Slate or tile fragments, pieces of mortar or bits of lead on the path tell you something has come off, even if you cannot see where from.
4. Look in the attic with a torch from the hatch or a safe boarded area. Daylight where there was none before, damp insulation or wet timber all need attention.
5. Take photos before anything is moved and send them to us. Our guide on which roof leak photos to send shows what is most useful.

Please do not go up a ladder or onto the roof to check for yourself. Storm-loosened slates and ridge tiles can give way without warning, and surfaces stay slippery long after the rain stops.

After a widespread Orange or Red event, every roofer in the region is busy. A temporary weatherproof cover is often the sensible first step, with the permanent repair following once materials and safe access are arranged. Our post on emergency roof leak repairs explains how that works.

Why exposure matters around Dublin and Wicklow

Because warnings are impact-based, the same colour can mean different things for different houses:

• Coast (Bray, Greystones, Howth, Malahide, Skerries): more exposure to onshore winds and salt, so fixings and flashings age faster. See our coastal roof maintenance checks.
• Higher ground (Wicklow uplands, Dublin Mountains foothills): stronger gusts and heavier rain on windward slopes.
• Open, flatter areas (Naas, Lucan, parts of North Dublin): few natural windbreaks around newer estates, with gable ends and verges taking the full force.
• Dublin City terraces: more shelter, but older slate roofs, tall chimney stacks and shared gutters mean one loose element can affect two homes.

If you have large trees near the house, read our guide to tree branch roof damage as well.

A quick checklist to keep

Worried about your roof before the next warning?

The best time to deal with a loose ridge tile or a slipped slate is on a calm day, before the forecast turns. If you have spotted something from the ground, or you want the roof checked ahead of the winter storms, we can help across Dublin City, North Dublin, South Dublin, Lucan, Bray, Wicklow and Naas.
