Emergency roofing: 083 158 8431

Water coming in, or something loose on the roof?

Ring 083 158 8431 if water is entering now, a ceiling is bulging, damage is worsening or roof material is loose. A falling piece can be a hazard even when there is no leak indoors; keep people clear of the area below and describe what you have already seen without going closer. For a dry old mark with no immediate hazard, use the form or our main line, 01 727 0010.

Until we speak: keep people and pets out from under a sagging ceiling and away from any area where loose material could drop, such as a path or driveway below the eaves. Put a basin or towels down only where the floor is safe to reach, and keep clear of water near lights, sockets or wiring; get qualified electrical help if needed. Please don't go onto the roof, put up a ladder, enter a wet or poorly boarded attic, or pierce a ceiling to let water out.

Emergency roofing is available 24/7, 365 days a year; call to check current availability. Same-day attendance is possible on some days but depends on location, weather, traffic, crew availability and safe access, and it is not guaranteed.

For the wider urgent service and its limits, see emergency roof repairs in Dublin.

Why we keep householders off the roof: HSA Code of Practice for Safety in Roofwork (falls, fragile surfaces, access and weather).

How a leak visit works: inspection first, then repair

We start from what you tell us about the leak's history and the weather it follows, then look at the covering, junctions and drainage that could feed the wet area, as far as safe access allows. Water can travel along felt or timber before it shows, so the stain marks where it appeared, not necessarily where it got in.

We then tell you what we confirmed and what is still uncertain. If a section couldn't be reached, or a finding depends on lifting slates or opening a flat-roof build-up, we say so and agree that step with you rather than guessing.

Where weather, access or materials prevent a lasting repair on the day, professional temporary protection may be possible where safe access allows. We explain its intended purpose, limitations and any follow-up needed, separately from the permanent repair. That next stage is agreed once the findings and suitable working conditions allow.

Where the source is unclear, see roof leak detection in Dublin.

Slates, tiles, ridges, hips and verges

On a pitched roof we look at the slates or tiles above the wet area, how they are fixed, and whether each course still overlaps the one below by enough to shed rain. Ridges and hips along the top and corners, verges at the gable ends, and the detail where this slope meets an adjoining roof or wall are checked as part of the same picture. Where the underlay can be seen through safe access, its condition may help the assessment; concealed areas are recorded as inspection limits.

A slipped slate or a crack in ridge mortar is worth noting, but it isn't automatically the whole cause of the water inside. Corroded or failed fixings are one possible reason a unit moves; others include broken units, disturbed overlaps or work done nearby. Whether a local repair is enough, or the slope needs wider attention, depends on the condition we find around it, not on one piece.

For pitched roof repair work generally, see roof repairs.

Chimney stacks, flashing and valleys

Damp beside a chimney breast can come from the stack itself (porous or cracked masonry, a failed cap, cracked flaunching around the pots) or from the joint between stack and roof (flashing that has lifted or split, or a back gutter on the uphill side holding debris). They are separate repairs, so we check them separately.

A valley, where two slopes meet, carries more water than the slopes either side. We look at the valley lining, the coverings cut to it, and whether runoff from a higher or neighbouring roof is landing on it harder than it was built to take.

For work on the stack, see chimney repairs.

For junction work, see lead flashing and valley repairs.

Flat roofs on porches, extensions and garages

Over a porch, a rear kitchen extension or a garage, we check seams and laps, edges and trims, upstands where the roof meets a wall, outlets, the falls that move water towards them and, where it can be assessed, the deck underneath. Water lying after rain may put extra stress on those details, but ponding on its own doesn't prove where the leak is.

If the layers under the surface are wet or unsound, that has to be assessed before choosing between a compatible patch and a wider refurbishment. No coating is a universal cure, and there is no fixed age at which a flat roof must be replaced; the choice follows the covering, the build-up and the defect.

For flat roof repair and replacement, see flat roofing.

Gutters and the roof edge

An overflowing gutter can soak a wall or push water back behind the roof edge, and from inside that can look the same as rain getting through the covering. We check whether the gutter is blocked, sagging or leaking at a joint, whether the downpipe discharges freely, and whether brackets are still supporting it, alongside the covering above.

If drainage is the cause, gutter work is quoted as its own item. Damage to the boards or supporting roof edge may need a separate roofline scope; our existing Swords fascia and soffit page explains that work without treating board replacement as a cure for every leak.

For boards at the roof edge, see fascia and soffit repairs in Swords.

For gutter and downpipe work, see guttering.

Rooflights: condensation or weathering?

Moisture at a rooflight may be condensation from warm indoor air meeting cold glazing, or rain getting past the flashing, upstand or seals around the unit. Where it shows, when it shows, and whether it lines up with rain or with cold, humid days all help us decide what to inspect, but none settles the cause alone. We don't recommend a replacement unit by default.

Access, shared details and who agrees the work

Let us know whether we can reach the affected roof by a side passage or only through the rear garden, and whether there is a lower extension or conservatory beneath the area we'd need to work over. Glazed or lightweight roofs below can't take ladders or foot traffic, so they shape how access is planned.

On semi-detached and terraced houses, a chimney stack, gutter run or valley may be shared with a neighbour. Tell us if you know that, and who else needs to agree work or access. Please give the actual address or Eircode of the property so we can plan the visit accurately.

What to tell us when you get in touch

A short description is enough to start. You don't need to name the roof material or the fault, and photos are optional; if you take any, do so only from a safe indoor position.

1. The room or area where water shows, and roughly where on the ceiling or wall.
2. Whether water is coming in now, has stopped, or keeps returning.
3. When it appears: during heavy rain, wind from one direction, after rain stops, or all the time.
4. Any earlier repairs to that part of the roof, and roughly when.
5. Access: side passage, rear only, lower extension or conservatory, shared stack or gutter.

What the written quotation sets out

Our free written quotation turns the inspection findings into an agreed scope. It identifies the work proposed, any further investigation needed and the applicable workmanship terms, so you can consider the repair before committing.

• The defect found, and anything still uncertain.
• The repair method and materials, and how they suit what's already there.
• Access: ladders, tower or scaffold, and who arranges it.
• Any temporary work and how it relates to the permanent repair.
• Protection for rooms, gardens or extensions below.
• Adjoining work needed for a sound repair, listed separately.
• Waste removal.
• Exclusions and areas that couldn't be inspected.
• Concealed damage: we stop, show you and get your approval before any extra work.
• The written workmanship terms that apply to the agreed work.

Local repair or wider renewal?

The useful question is what a proposed repair will put right and what will remain. Replacing a damaged unit or renewing a junction may deal with a defined fault while leaving other parts of the roof untouched. We identify those boundaries and any separate deterioration that could need attention later.

If defects extend across the covering, fixings or supporting build-up, we discuss whether a wider section needs refurbishment or renewal. The observed condition, compatible materials, access and likely scope inform that choice; neither a single leak nor the roof's age alone establishes that replacement is necessary.

For replacing a failing roof on an existing home, see new roofs and re-roofing.

After the repair

What the repair covers is set out in the quotation and its written terms. Plaster and timber take time to dry and old stains can stay visible, so a mark alone doesn't show whether the roof is sound. Fresh wetness after rain does warrant a fresh look, though it doesn't prove where the water came from.

If that happens, tell us the room, the dates and the weather; a description is enough, and photos are optional and only from a safe indoor position. Any permanent work outstanding after temporary protection should remain clearly identified in the agreed scope, with the next step arranged subject to weather and safe access. To get started, use the form on this page or call 01 727 0010.
