Winter in Dublin is relentless. Months of driving rain, freezing temperatures, and gale-force winds take their toll on every roof in the city. By the time March arrives, your roof has endured the worst that Irish weather can throw at it — and the damage is not always obvious from the ground.
A spring roof inspection is the single most important thing you can do to protect your home and avoid costly repairs later in the year. Catching problems early — a cracked slate, a lifted flashing, a blocked gutter — can save you thousands. At JD Roofing, we carry out detailed roof inspections across Dublin, Kildare, Meath, and Louth every spring. Here is our expert checklist to help you understand what to look for.
The 10-Point Spring Roof Inspection Checklist
1. Check for Missing, Cracked, or Slipped Slats and Tiles
Start with the most visible issue. Look at your roof from the ground with binoculars or ask a neighbour to check from an upstairs window. Missing or displaced slates are a common consequence of winter storms. Even a single missing slate or tile can allow water to penetrate the felt and timber beneath, leading to interior damp and costly structural damage.
What to look for: Gaps in the roof surface, slates sitting at odd angles, cracked or broken tiles, fragments of slate or tile on the ground around your property.
2. Inspect the Ridge Tiles Along the Peak of Your Roof
The ridge tiles along the top of your roof are held in place with mortar, which degrades over time. Winter frost accelerates this process by expanding and contracting the mortar joints. Loose or missing ridge tiles are a major entry point for rainwater.
What to look for: Ridge tiles sitting unevenly, visible gaps in the mortar between tiles, ridge tiles that have fallen or shifted. If the mortar looks crumbly or dark, it likely needs repointing.
3. Examine the Chimney Stack and Flashing
Your chimney is one of the most exposed parts of your roof. The mortar between the bricks can crack and crumble, the chimney pot may have shifted, and the lead flashing where the chimney meets the roof is a notoriously common source of leaks. Winter storms often loosen or lift flashing that was perfectly secure before.
What to look for: Crumbling mortar on the chimney stack, gaps between the flashing and chimney or roof surface, water stains on the ceiling or walls near the chimney inside your home.
4. Check All Gutters and Downpipes
Blocked or damaged guttering is one of the most common causes of water damage to Irish homes — and one of the easiest to prevent. Over winter, gutters fill with leaves, moss, and debris from the roof. If water cannot flow freely, it overflows against the fascia board and can seep into the roof space, walls, and foundations.
What to look for: Overflowing gutters during rainfall, sagging gutter sections, visible plant growth in the gutter channel, water stains or damp patches on exterior walls beneath the roofline.
5. Inspect Fascia Boards and Soffits
The fascia boards and soffits run along the lower edge of your roof, supporting the guttering and protecting the roof timbers from the elements. Timber fascias are particularly vulnerable to rot after a wet winter. Even uPVC fascias can crack or come loose in severe weather.
What to look for: Peeling paint or visible rot on timber fascia boards, gaps between the fascia and the wall, soffits that are sagging or have come away from the roofline. Any softness in the timber when prodded is a sign of rot.
6. Look for Signs of Moss, Algae, and Lichen
Dublin’s damp climate makes moss growth on roofs almost inevitable, especially on north-facing and shaded areas. While a thin layer of moss is mostly cosmetic, heavy growth retains moisture against the roof surface and can lift slates or tiles over time. Spring is the ideal time to arrange a professional roof clean before moss growth accelerates in the warmer, wetter months ahead.
What to look for: Thick patches of green moss across the roof surface, dark streaks of algae, and lichen growth around the edges of individual slates or tiles.
7. Check the Roof from Inside Your Attic
One of the most revealing inspections you can do requires no ladders at all. Go into your attic on a dry day and look up. If daylight is visible through the roof boards, you have gaps that need attention. Also, look for water stains, damp timber, or any signs of condensation.
What to look for: Pinpoints of daylight through the roof, dark water stains on rafters or battens, damp or musty smells, condensation on the underside of the roof felt.
8. Inspect Flat Roof Sections
If your home has any flat roof sections — over an extension, garage, or porch — these need particular attention after winter. Flat roofs are more vulnerable to standing water, and the membrane can develop cracks, blisters, or splits during freezing weather.
What to look for: Pooling water that does not drain within 48 hours, blisters or bubbles in the membrane surface, cracks around the edges where the flat roof meets the wall, and any visible tears or splits in the material.
9. Check Roof Valleys and Junctions
Roof valleys — the V-shaped channels where two roof slopes meet — are high-risk areas for leaks. They channel large volumes of rainwater and are lined with lead or mortar that can degrade over time. After winter, check that valley linings are intact and free of debris.
What to look for: Debris accumulation in valleys, visible cracks or gaps in valley linings, water stains on interior walls below a valley location.
10. Look for Sagging or Structural Deformation
Stand back from your property and look at the roofline. It should be straight and even. Any visible sagging, dipping, or bowing in the roof structure indicates a potentially serious problem with the underlying timbers. This is not a DIY fix — contact a professional roofing contractor immediately if you notice any structural deformation.
What to look for: A dip or bow in the ridge line, sections of the roof that appear to sag or bulge, any visible distortion when viewing the roof from a distance.
Found a Problem? Here’s What to Do Next
If your spring inspection reveals any issues — no matter how minor they may appear — the worst thing you can do is wait. Small problems on a roof grow quickly. A cracked slate that costs €200 to replace today can cause €2,000+ in water damage if left through another season of rain.

Why a Professional Inspection Beats a DIY Check
While the checklist above is a great starting point, there are many issues that are simply impossible to spot from the ground. Hairline cracks in slates, deteriorating felt beneath the tiles, early-stage rot in timber battens, and subtle flashing failures all require a trained eye and safe roof access.
A professional inspection by JD Roofing includes a detailed assessment of every element of your roof — covering, structure, drainage, flashings, and ventilation. We provide a clear written report of our findings and recommendations, so you can make informed decisions. If emergency repairs are needed, we can often address them on the same visit.
Frequently Asked Questions About Spring Roof Inspections
Q: How often should I have my roof inspected in Dublin?
A: We recommend a professional roof inspection at least once a year, ideally in spring after the winter storms. Properties with older roofs, mature trees nearby, or previous repair history may benefit from twice-yearly inspections.
Q: Can I inspect my own roof safely?
A: You can carry out a visual check from the ground using binoculars, and you can inspect from inside your attic space. However, we strongly advise against climbing onto the roof yourself. Professional roofers have the equipment, training, and insurance to work safely at height.
Q: How much does a professional roof inspection cost in Dublin?
A: JD Roofing offers free, no-obligation roof inspections across Dublin, Kildare, Meath, and Louth. Call us on 087 389 3446 to arrange yours.
Q: What happens if the inspection finds damage?
A: We will explain exactly what we have found, show you photographs where possible, and provide a clear, itemised quote for any recommended repairs. There is no obligation and no pressure. You decide if and when to proceed.
Q: Is spring really the best time for a roof inspection?
A: Yes. Spring is ideal because it falls after the harshest weather of the year and before the summer building season. Problems caused by winter storms are still fresh and visible, and addressing them in spring prevents further deterioration through the wetter months ahead.
Q: Do you cover areas outside Dublin?
A: Yes. JD Roofing provides roof inspections and repairs across Dublin, Kildare, Meath, and Louth. Contact us for a free site visit.
