Asbestos roof encapsulation for Ennis farm buildings, factories and warehouses — no strip-out, no disposal of the sheets. Asbestos cement roofs are common on agricultural and industrial buildings across Ennis and the wider County Clare 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.

Ennis is the county town of Clare and the headquarters of Clare County Council, which covers the town through its Ennis Municipal District, alongside the Shannon, Killaloe and West Clare districts. At Census 2022, Ennis had 27,923 people. As the administrative and service centre for the county, the town draws in people and businesses from a wide rural hinterland, and its roofs range from town-centre commercial premises and older workshops to the farm buildings that ring its edges.
That hinterland is shaped by the farming Teagasc describes for its Galway and Clare advisory region: suckler, sheep and mixed drystock farming predominate, with dairying more concentrated on the lowlands, and the region as a whole counts around 20,000 farmers. Around a town like Ennis that means cattle sheds, sheep housing, haybarns, dairies and machinery stores, plus the stores and workshops of the businesses that serve farmers. Corrugated asbestos cement was a standard sheet for exactly those kinds of building for decades, and many of those roofs are still in place.
Met Éireann’s Shannon Airport station, a short distance south of Ennis, is the reference for local weather. Over 1991 to 2020 it averaged 1,019.7 mm of rain a year, with 1 mm or more on about 168 days. Wet weather on that many days slowly erodes the cement surface, lets moss and lichen build up and works at the fixings and laps. Encapsulation seals an asbestos cement roof where it is. Gaco urethane coatings, U91 and U92 being the grades used on asbestos cement, are applied over the existing sheets, so nothing is stripped and the building stays in use. An approved installer surveys, replaces sheets that are broken, cleans without abrading the cement and applies the coating in dry spells within Gaco’s limits. Duratite supplies the materials, and the approved installer carries out the work.
Whether the roof is on a town-centre workshop or a farm outside Ennis, the Safety, Health and Welfare at Work (Exposure to Asbestos) Regulations 2006 (S.I. No. 386 of 2006, as amended) apply, and the Health and Safety Authority enforces them. The installer’s risk assessment deals with notification and with safe access, since asbestos cement will not bear a person’s weight. Clare County Council is the building control authority, and TGD L 2022 applies if insulation is changed. The island-of-Ireland reference project for asbestos roof encapsulation is SAICA Warrenpoint, Co. Down.
When enquiring about a building in or around Ennis, say whether it is a town premises or a farm building, what happens inside, and when it is busiest. Photos of the roof from the ground and of any leaks inside are a good starting point for the installer.
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.
Removal needs specialist contractors, disposal and a replacement roof. Encapsulation leaves the sheets in place.
Livestock sheds, stores and production buildings cannot easily be emptied for a roof replacement.
Hairline cracks, failed laps and fixings let water in. The coating system bridges and seals them across the whole roof.
Older sheets lose their surface, grow moss and lichen and become porous. Encapsulation seals that weathered surface.

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 Ennis 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 Ennis.
Straight answers to the questions building owners and managers ask most often.
Yes. Duratite Ireland takes enquiries from Ennis and the wider County Clare area and routes them to an approved installer of the GacoFlex asbestos roof system who covers County Clare. We do not have a branch office in Ennis; the survey and application are carried out by the approved installer.
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.
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.
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.
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.
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.
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.
If the sheets and the structure are sound, encapsulation is often a practical alternative to replacement. The approved installer’s survey confirms the condition, identifies any sheets to replace and sets out the steps under the Exposure to Asbestos Regulations 2006, as amended.
The roof must be dry and within Gaco’s application limits during coating and curing. With around 168 wet days a year at Shannon Airport, installers plan around dry windows and keep dates flexible.
Only for building control, and only if the project adds or changes insulation, when TGD L 2022 applies. The asbestos work itself is regulated by the Health and Safety Authority.
