Gaco Asbestos Roof Waterproofing in County Cork — Encapsulation Without Removal
Asbestos roof encapsulation for County Cork farm buildings, factories and warehouses — no strip-out, no disposal of the sheets. Removing an asbestos cement roof in County Cork means specialist removal, disposal and a building without a roof until it is replaced. Where the sheets are still structurally sound, the GacoFlex asbestos roof system seals and waterproofs them in place instead.

Local context
Asbestos cement roof coatings for County Cork farms and harbour sites
County Cork is Ireland’s largest county, and asbestos cement turns up on roofs right across it: dairy sheds and haybarns on farms throughout the county, older stores and workshops around Cork Harbour, and outbuildings along the peninsulas and inlets of the Atlantic coast. The harbour economy is still substantial — the Port of Cork’s sites at Tivoli, Ringaskiddy, Cobh and Belvelly handle about 10.5 million tonnes a year — and corrugated asbestos cement was a standard roofing sheet for industrial and agricultural buildings for decades before it was banned.
Weather is what wears those sheets out. Met Éireann’s Cork Airport station averaged 1,239 mm of rain a year over 1991–2020, with around 162 days of at least 1 mm. Years of that wet, mild climate soften and erode the cement surface, moss and lichen take root, and fibres at the surface become less firmly bound. Cracked sheets and rusted fixings let water in well before a roof looks close to collapse. Buildings on exposed coastal and upland ground take the brunt of Atlantic weather, and the wear usually shows first on ridges, eaves and verges.
Encapsulating the roof with Gaco urethane coatings — U91 and U92 are the grades used on asbestos cement — seals the weathered surface under a continuous waterproof film, avoiding the stripping and disposal of the sheets. The approved installer surveys first: broken or badly distorted sheets may need replacing, and the cleaning method must not abrade the cement. Coating only proceeds when the forecast offers a dry spell and surface conditions sit within Gaco’s application limits, which in Cork often means planning around the weather rather than fixing a date months ahead. Duratite supplies the coating system; the installer carries out the job. Gutters and valleys are checked at the same time, since blocked or leaking gutters keep sheet ends permanently wet.
In the Republic, work that could disturb asbestos is governed by the Safety, Health and Welfare at Work (Exposure to Asbestos) Regulations 2006, as amended most recently by S.I. No. 632 of 2025, and the Health and Safety Authority publishes a 2025 Code of Practice to go with them. The installer’s risk assessment decides how the job is classified and whether the HSA must be informed in advance. Asbestos cement sheets are fragile, so safe access is designed in from the start. For buildings outside the city boundary, Cork County Council’s Fire and Building Control department is the local authority contact.

Why encapsulate in County Cork
Four reasons County Cork building owners choose encapsulation
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.
Leaks through cracks and laps
Hairline cracks, failed laps and fixings let water in. The coating system bridges and seals them across the whole roof.
Buildings that must stay in use
Livestock sheds, stores and production buildings cannot easily be emptied for a roof replacement.

Republic of Ireland regulations
Asbestos regulations for roof work in County Cork
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 County Cork 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 County Cork.
County Cork questions answered
Asbestos roof waterproofing FAQs · County Cork
Straight answers to the questions building owners and managers ask most often.
Do you treat asbestos cement roofs in County Cork?
Yes. Duratite Ireland takes enquiries from County Cork and routes them to an approved installer of the GacoFlex asbestos roof system who covers County Cork. We do not have a branch office in County Cork; the survey and application are carried out by the approved installer.
Which regulations apply to asbestos roof work in County Cork?
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.
How much does asbestos roof encapsulation cost in County Cork?
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.
Can the building in County Cork 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.
Can my asbestos roof in County Cork 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.
How far ahead do I need to book asbestos roof work in County Cork?
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.
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.
Does Cork’s rainfall affect when an asbestos cement roof can be coated?
Yes. The sheets must be dry and the surface temperature and weather within Gaco’s application limits, both while coating and while it cures. With around 162 wet days a year at Cork Airport, installers watch forecasts closely and book work into dry windows, sometimes pausing mid-job. Late spring to early autumn usually gives the most reliable spells, but no date is guaranteed.
Can a moss-covered farm roof in West Cork be encapsulated?
Often, yes. Moss and lichen have to be killed and removed first using a method that does not abrade the cement, so aggressive scraping or high-pressure blasting is avoided. Broken sheets are replaced, and the approved installer’s method statement sets out how cleaning water and debris are controlled before the Gaco coating is applied.
Do I have to remove an asbestos roof rather than coat it?
Not necessarily. If the sheets and structure are sound, encapsulation is a recognised alternative that avoids disturbing the roof, the waste and the downtime of removal. If sheets are badly broken or the structure has failed, replacement may be the right answer. The installer’s survey sets out the options, and the asbestos regulations apply whichever route you take.
