Agricultural Roofing in Ireland: Everything You Need to Know
At O'Connor Roofing Supplies, we have been supplying roofing materials to farmers and agricultural contractors across Ireland since 1980. In that time, we've helped with thousands of agricultural building projects — from small farm shed extensions to large-scale commercial livestock units. This guide covers the key decisions you need to make when planning an agricultural roofing project in Ireland.
The Most Common Roofing Materials for Agricultural Buildings
The right roofing material depends on the type of building, your budget, and whether you intend to heat the space. Here are the main options:
Corrugated Sheeting
The traditional choice for Irish farm buildings. Corrugated steel sheeting in 0.5mm or 0.6mm gauge is durable, cost-effective and widely available. The 0.6mm polyester-coated version is the TAMS II grant approved specification. Available in a range of colours including Slate Grey and Juniper Green.
Box Profile Sheeting
A modern alternative to corrugated, box profile offers a cleaner appearance and marginally greater structural rigidity. Also available in TAMS II approved specification. Popular for newer agricultural buildings where aesthetics matter alongside function.
Kingspan Insulated Panels
For buildings that require thermal performance — heated livestock buildings, food processing units, grain stores, dairy parlours — Kingspan QuadCore insulated panels are the premium choice. Available in core depths from 40mm to 150mm, they significantly reduce heat loss and can contribute to compliance with building energy regulations.
Fibre Cement Sheeting
Fibre cement (Profile 6) is a grant-accepted, maintenance-free and corrosion-resistant option. It is particularly well-suited to livestock environments where ammonia from animal waste can corrode metal sheeting over time. It requires no painting or maintenance and has a very long service life.
Non-Drip / Anti-Condensation Sheeting
Condensation is one of the most common problems in agricultural buildings — particularly unheated sheds in the Irish climate. Non-drip sheeting has a fleece-like coating applied to the underside that absorbs condensation and prevents it dripping onto animals, machinery or fodder. It's a cost-effective alternative to insulated panels for buildings where condensation control is needed but full thermal insulation is not required.
Key Structural Components
A well-built agricultural roof requires more than just the sheeting. The structural components include:
- Purlins — the horizontal members that the sheeting is fixed to. Kingspan Multi Beam purlins and pre-painted agri purlins are the most common choices for agricultural frames in Ireland.
- Flashings — the metal trims at ridges, barges, eaves and junctions that keep water out. Colour-matched to your sheeting and cut to length at O'Connor Roofing.
- Guttering — standard galvanised or highline guttering to manage rainwater runoff from the roof. Correctly sized guttering is essential for protecting the building's foundations and surroundings.
- Rooflights — clear polycarbonate or GRP rooflights allow natural light into the building, reducing the need for artificial lighting. Available in corrugated, box profile and Kingspan panel profiles.
- Fixings — the correct screws, storm washers and caps for your sheeting profile and purlin type are essential for a weathertight, long-lasting roof.
TAMS II Grant for Agricultural Roofing
If you are building or re-roofing an agricultural structure in Ireland, the TAMS II (Targeted Agricultural Modernisation Scheme) grant can cover up to 40% of approved material costs (60% for young farmers). To qualify for the roofing grant, the sheeting must meet the Department of Agriculture's specification:
- Minimum 0.6mm gauge steel
- Polyester coated finish
- Colour: Slate Grey or Juniper Green only
O'Connor Roofing stocks both corrugated and box profile sheeting that meets this specification. We can also provide product documentation to support your TAMS II payment claim.
Choosing a Roofing Supplier for Your Agricultural Project
When choosing a roofing supplier for an agricultural build, the key factors to consider are:
- Stock availability — a large, well-stocked supplier can fulfil your order quickly and avoid delays on your build programme
- Cut-to-length service — having sheets cut to your exact specifications before delivery saves time and reduces waste on site
- Trade pricing — agricultural projects typically involve significant volumes; a supplier with dedicated trade pricing will offer better value
- Technical knowledge — your supplier should be able to advise on the correct specification for your project, including grant eligibility
- Nationwide delivery — especially important for remote or rural locations

Frequently Asked Questions
How long does a steel agricultural roof last?
A well-installed steel roof in 0.6mm or 0.7mm gauge with a quality polyester or PVC coating will typically last 25–40 years with minimal maintenance. The longevity depends on the coating quality, gauge, local environment and quality of installation.
What is the best roofing for a cattle shed in Ireland?
For a cattle shed, non-drip or anti-condensation sheeting is strongly recommended to prevent condensation drip onto animals. A 0.6mm corrugated or box profile with non-drip coating in the TAMS II approved Slate Grey or Juniper Green is the most common specification for new cattle housing in Ireland.
Do I need planning permission for a new agricultural shed in Ireland?
Many agricultural buildings are exempt from planning permission in Ireland under certain conditions, but this depends on the size, location and intended use. You should always check with your local authority or planning consultant before commencing works.
