Gaco Asbestos Roof Waterproofing in Limerick — Encapsulation Without Removal
Keep ageing asbestos cement roofs in Limerick in place, sealed and watertight with the GacoFlex asbestos roof system. Asbestos cement roofs are common on agricultural and industrial buildings across Limerick and the wider County Limerick area. Encapsulation is a survey-led way to deal with weathered sheets: they are prepared, sealed with GacoFlex encapsulation coatings and made watertight, without removal.

Local context
Asbestos cement roof encapsulation around Limerick and the Shannon
Older industrial estates around Limerick city and farmland across the county both carry plenty of corrugated asbestos cement. Along the estuary, Shannon Foynes Port Company — Ireland’s largest bulk-port company, with capacity for more than 10 million tonnes a year — oversees marine activity from Kerry up to Limerick City, and bulk trade depends on large storage sheds. In the city, the Shannon stays tidal as far upstream as the Ardnacrusha dam, and quayside and riverside buildings sit in damp air for much of the year. Farms in the Limerick part of the Golden Vale add dairy sheds, haybarns and machinery stores to that stock, many roofed when asbestos cement was the standard choice.
Met Éireann’s Shannon Airport station, the nearest long-term reference, recorded 1,019.7 mm of rain a year over 1991–2020 and roughly 169 days with 1 mm or more. That persistent moisture is what wears asbestos cement roofs down: the surface erodes slowly, lichen takes hold, and sheets turn brittle and crack at edges and fixings. Leaks tend to show first around rooflights, ridges and laps. Industrial roofs with plant, vents and flues built through the sheets tend to leak first at those penetrations.
Coating with Gaco U91 or U92 urethane encapsulates the weathered sheets in a seamless waterproof film and avoids the disturbance, disposal and downtime of stripping the roof. For an industrial unit, that can allow the business to keep operating below while the approved installer works above — subject to their risk assessment. Preparation must avoid abrading the cement, broken sheets are replaced, and application waits for a dry window with surface conditions inside Gaco’s limits. Duratite supplies the system and puts Limerick clients in touch with an approved installer. Roof-mounted plant is protected or worked around rather than removed where possible, and gutters are cleared.
Throughout the Republic, the Safety, Health and Welfare at Work (Exposure to Asbestos) Regulations 2006, as amended, govern any work that might disturb asbestos, and the Health and Safety Authority is the enforcing body. Its 2025 Code of Practice explains how the regulations work in practice. Asbestos cement sheets cannot be relied on to bear a person’s weight, so access is planned from the ground up. Limerick City and County Council handles building control for the city and county alike. The installer confirms whether the work is notifiable and leaves a record of the risk assessment and method statement for the owner’s files.

Why encapsulate in Limerick
Four reasons Limerick building owners choose encapsulation
Buildings that must stay in use
Livestock sheds, stores and production buildings cannot easily be emptied for a roof replacement.
Cost and disruption of removal
Removal needs specialist contractors, disposal and a replacement roof. Encapsulation leaves the sheets in place.
Weathered asbestos cement sheets
Older sheets lose their surface, grow moss and lichen and become porous. Encapsulation seals that weathered surface.
Fragile roof access
Asbestos cement sheets are fragile. The work is planned with safe access so no one relies on the sheets for support.

Republic of Ireland regulations
Asbestos regulations for roof work in Limerick
Work on asbestos-containing materials in the Republic of Ireland is governed by the Safety, Health and Welfare at Work (Exposure to Asbestos) Regulations 2006 (S.I. No. 386 of 2006, as amended by S.I. No. 589 of 2010 and S.I. No. 632 of 2025).
Since the 2025 amendment, notifiable asbestos work needs an HSA permit before it starts, supported by the notification, a plan of work and a risk assessment. The installer’s programme for your Limerick roof builds that lead time in.
Every project is survey-led and risk-assessed, and notified to the Health and Safety Authority (HSA) where required.
Because the sheets stay in place, they remain part of the building’s asbestos records after the work in Limerick.
Limerick questions answered
Asbestos roof waterproofing FAQs · Limerick
Straight answers to the questions building owners and managers ask most often.
Do you treat asbestos cement roofs in Limerick?
Yes. Duratite Ireland takes enquiries from Limerick and the wider County Limerick area and routes them to an approved installer of the GacoFlex asbestos roof system who covers County Limerick. We do not have a branch office in Limerick; the survey and application are carried out by the approved installer.
Does encapsulation mean the asbestos is gone?
No. Encapsulation seals the asbestos cement sheets and makes the roof watertight, but the sheets stay in place, so they remain part of the building’s asbestos records.
How far ahead do I need to book asbestos roof work in Limerick?
Allow for the survey, the specification and the HSA permit, which must be in place before notifiable asbestos work starts. The installer plans the programme around it.
Can my asbestos roof in Limerick be treated without removing it?
If the survey finds the sheets structurally sound, yes. The roof is prepared, sealed with GacoFlex U91 and U92 encapsulation coatings and, where specified, finished with a GacoFlex silicone topcoat. The sheets stay in place, so there is no removal or disposal.
Can the building in Limerick stay in use during the work?
Often, yes, because the work is carried out on the roof with the sheets left in place. The installer’s risk assessment sets out any restrictions for your building.
How much does asbestos roof encapsulation cost in Limerick?
It depends on roof area, condition, access and the specification, so we do not publish prices. After the free survey you receive a written quotation in euro from the approved installer.
Which regulations apply to asbestos roof work in Limerick?
In the Republic of Ireland, the Safety, Health and Welfare at Work (Exposure to Asbestos) Regulations 2006, as amended most recently by S.I. No. 632 of 2025. Notifiable asbestos work now needs an HSA permit before it starts, supported by the notification, a plan of work and a risk assessment.
Can my Limerick business stay open while its asbestos roof is coated?
In many cases, yes. Encapsulation is carried out from above and does not involve removing the sheets, so operations below can often continue. The installer’s risk assessment decides whether any areas need clearing — for example beneath rooflights, broken sheets being replaced, or roof access points — and the programme is agreed with you in advance.
Does estuary damp shorten the life of an asbestos cement roof?
Moisture is one of the main drivers of weathering, so roofs in damp, mild conditions tend to show moss, lichen and surface erosion. There is no fixed lifespan, though; condition depends on age, exposure and maintenance. A survey tells you whether the sheets are still sound enough to encapsulate or whether replacement is needed.
Is it better to over-clad or coat an asbestos cement roof in Limerick?
It depends on the roof and the building. Over-cladding adds a new sheet on top, which adds load and usually means fixing through the existing roof. Coating seals the existing sheets without adding a new layer. Structure, sheet condition, insulation needs and budget all play a part, so the installer’s survey is the starting point.
