Roof Leak Repairs in Tallaght

Tell us about the leak

The affected room or area, whether it's active now, and any earlier repairs.

Emergency roofing: 083 158 8431

Active leak or old mark? Start here

If water is dripping now, a ceiling is sagging or the roof looks unsafe, ring 083 158 8431 rather than waiting on a form reply. If the mark is dry and hasn't grown, the form or our main line, 01 727 0010, is fine. Emergency roofing is available 24/7, 365 days a year; call to check current availability. Same-day attendance depends on location, weather, traffic, crew availability and safe access, and it is not guaranteed.

Indoors, keep people away from a bulging ceiling and from water near sockets, lights or wiring, and get qualified electrical help if needed. Use a basin or towels only where the floor area is safe. Please don't climb onto the roof, put a ladder to the gutter or go into a wet or unsafe attic to look.

Where conditions or access prevent a lasting repair, we may recommend professional temporary weatherproofing. That's protection, not the fix: we tell you what it covers, its limits and what permanent work still needs to follow once the weather and diagnosis allow.

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

What helps us plan the visit

Water often runs along timbers, felt or a ceiling joist before it shows, so the stain inside may be some distance from where it got in. That's why a few details from you narrow down what we look at first.

1. Address or Eircode for the actual property.
2. The room or area: bedroom ceiling, kitchen under an extension, shop or office unit, stairwell.
3. The roof zone above it if you know: main slope, flat roof, dormer, chimney side, rooflight.
4. Timing: during heavy rain, wind from one direction, after rain stops, or constantly.
5. Whether it's active, has stopped, or keeps returning.
6. Access: side passage, rear garden only, shared yard, parking or loading restrictions, opening hours.

It was patched before and it's back

Tell us what was done before, roughly when, and on which part of the roof. A receipt or a note of the scope helps. A returning leak doesn't automatically mean the earlier work was poor; the water may be coming from a connected entry point, a nearby outlet that overflows, or a wider condition the patch was never meant to cover.

We look at the repaired spot and what surrounds it. If a junction or drainage fault outside the earlier scope needs attention, we explain how that relates to the present leak and separate the proposed work in the quotation.

For how an uncertain source is investigated, see roof leak detection in Dublin.

Slates, tiles, ridges and verges

On a pitched roof we check the slates or tiles over the wet area, their fixings and the overlap between courses, the ridge and its bedding, and the verges at gable ends. Where the attic can be entered safely, we look at the underlay from inside for tears or staining; if it can't, we say which parts weren't seen.

Failed fixings are one possible reason a slate slips, not the only one. If slates keep moving in different places, we look at the wider slope before agreeing to replace pieces one at a time.

For pitched roof repair work generally, see roof repairs.

Flat roofs over extensions, garages and occupied rooms

A flat roof over a kitchen, a garage or a ground-floor business space is checked at its seams and laps, edges and trims, outlets, falls, upstands, rooflight kerbs and, where it can be judged, the deck underneath. Water that sits after rain may put extra stress on those details, but ponding on its own doesn't prove where a leak is.

If the build-up under the surface is wet or unsound, it needs assessing before choosing repair or refurbishment. Another surface patch or coating may leave an underlying problem unresolved. We explain what the inspection shows, the compatibility of proposed materials and whether further investigation is needed first.

Chimneys, valleys and wall junctions

Damp on a chimney breast can come from the flashing, but also from porous or cracked masonry, the cap or flaunching, or a back gutter on the uphill side that's holding silt. We check the stack and the leadwork separately because the repairs differ.

Valleys and abutments, where slopes meet or a roof meets a wall, are inspected with the coverings beside them. Runoff from an adjoining roof that discharges onto yours can also overload a detail, so we look at where that water lands.

If the stack itself needs work, see chimney repairs.

Gutters, outlets and downpipes

A blocked outlet or sagging gutter can push water back under the roof edge or down a wall and look just like a roof leak from inside. We check falls, joints, outlets and downpipe discharge alongside the covering above.

If drainage is the cause, the gutter work is quoted as its own scope. If the covering is also damaged, that's listed separately, so you can see what each part addresses.

For gutter work, see guttering.

Where boards behind the gutter are affected, see fascias and soffits.

Rooflights: condensation or weathering?

Water near a rooflight may be condensation from warm indoor air on cold glazing, or rain getting past the surrounding flashing, upstand or seals. Where the moisture shows, when, and in what weather all inform what we inspect, but none of them settles the cause alone. We don't assume a new unit is needed by default.

Shared, occupied and protected buildings

For apartments, terraces, shops or offices, tell us who controls the roof and any common areas, and who needs to agree access. We arrange safe working around opening hours, deliveries, loading areas and people below, and agree a repair boundary where a gutter, parapet or stack is shared.

South Dublin County Council identifies a bounded Architectural Conservation Area in Tallaght Village, not a designation covering Tallaght generally. Where protection may apply, check the particular address and proposed work with the council before agreeing changes to roof materials or details.

What the written quote covers

Quotations are free and written. We don't price a leak over the phone because the cause, access and materials decide the cost.

• The roof zone and defect, and the repair method.
• Materials, and how they relate to what's already there.
• Access: ladders, tower or scaffold, and who arranges it.
• Protection for rooms, stock, gardens or extensions below.
• Any adjoining work needed for a sound repair.
• Waste removal.
• Exclusions and areas that couldn't be inspected.
• Concealed damage: we stop, show you and get approval before any extra work.
• The workmanship terms that apply to the agreed work.

Local repair or wider renewal?

Where there's one defined defect and the surrounding roof is sound, a local repair may be the sensible answer. We tell you plainly what that repair leaves untouched, such as worn sections elsewhere or a tired flat-roof build-up, so you aren't surprised later.

Where an existing roof is failing across several areas, repeated patching can cost more over time than a planned renewal. We set out both options with the reasons, based on condition rather than age.

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

After the repair

Plaster and timber can take a while to dry and old stains can stay visible, so a mark alone doesn't tell you whether the roof is sound. Fresh wetness after rain warrants reassessment, but it doesn't confirm the source by itself.

If it happens, contact us with a description, the room and the dates and weather; that's enough to arrange a follow-up. Photos are optional and only from a safe indoor position. If temporary protection was fitted first, we explain the outstanding permanent work and agree the next step subject to suitable conditions and safe access. To get started, use the form on this page or call 01 727 0010.
