5 Why insulate

Where the heat's going

A big share of a home’s heat escapes straight up through an uninsulated or under-insulated roof. You feel it as cold rooms and pay for it on the heating bill.

Cold rooms & high bills

Heat rises, and a poorly insulated roof lets a lot of it out. You end up heating air that disappears through the ceiling.

Damp & condensation in the attic

Insulation done badly, or stuffed into the eaves, blocks the airflow and traps moisture, which shows up as black mould and damp timber.

A cold attic conversion

A room in the roof that never holds its heat usually needs proper insulation along the rafters, the sloping timbers, not just across the floor.

What's included

Our roof insulation service

We pick the right method and material for your roof and fit it so it actually performs.

  • Attic (loft) insulation. Mineral wool laid between and over the ceiling joists, the quickest, best-value win for most homes
  • Rafter insulation. Rigid boards fitted between the sloping rafters, to keep a converted attic or room in the roof warm
  • Pitched roof insulation, and flat roof insulation done properly as a warm roof
  • Kingspan and other rigid PIR boards, mineral wool, and the right depth for the job
  • Topping up or replacing old, thin or compressed insulation
  • Insulating the cold water tank and pipes, and keeping the eaves vents clear so the roof can still breathe
  • Honest advice on materials, including the cautions around spray foam
  • A written, fixed price before any work, and workmanship cover

What it costs

Roof insulation cost in Dublin

Attic insulation is usually one of the best-value upgrades you can make, and it pays back in lower bills. Rafter insulation costs more because there’s more area and more work. What moves the price is the type of insulation, the area to cover, whether old material has to come out, and the access. An SEAI grant may be available for attic insulation, which can cover a good part of the cost. Use the calculator for a guide, then book a free survey, and we’ll put a fixed price in writing.

What affects the price

  • Method: attic (loft) or rafter insulation
  • Material: mineral wool or rigid board
  • Area to cover and the depth needed
  • Removing old or damaged insulation
  • Access, and any roof repair needed first

FAQS

Frequently Asked Questions

Direct answers from an experienced, hands-on roofing professional.

Yes. SEAI offers a grant towards attic insulation for homes built and occupied before 2011, and the work has to be done by an SEAI-registered contractor. Grant amounts and the rules change, so check the current details on the SEAI website and ask us whether your job qualifies.

Attic or loft insulation goes flat across the ceiling joists, keeping heat in the rooms below and leaving the attic cold. Rafter insulation follows the slope of the roof, so the attic itself stays warm and usable, which is what you want for a converted attic or room in the roof.

Spray foam can cause trouble when you sell or remortgage, because some lenders and surveyors are wary of it, especially when it’s sprayed onto the underside of the roof. We’ll give you honest advice on the right material for your home rather than push one product.

A good thick layer of mineral wool across the attic floor, laid to the depth current guidance recommends. The two things that matter most are not compressing it and not blocking the eaves vents so you get the warmth without trapping moisture. We’ll spec the right depth for your home.
