Step 1 of 7

What size is the garage?

Measure it roughly from outside: the roof and floor are priced by size.

How the estimate is worked out

Roof and door ranges are what Irish roofers and door companies publish for the same job: the lowest to the highest figure. A double garage roof is its area times the rate for the covering. Floors, walls, windows, insulation and electrics vary too much from garage to garage to price fairly without seeing them, so the builder prices those on a visit.

Before anyone starts

  • Roof firsta dry garage before anything else
  • Pre-2000fibre-cement sheets may hold asbestos
  • 30 m²of garage or shed without planning
  • Door lastso the work doesn't damage it

Roof first, so the garage is dry; then walls and windows; then electrics; then the floor; and the door last, so it isn't knocked about by the work. Insulation goes in before the walls are finished if the garage is to be heated. Corrugated or flat fibre-cement sheets on a garage built before 2000 may contain asbestos: Ireland banned asbestos products from 1 April 2000.

What order should a garage be renovated in?

Roof first, so the garage is dry; then walls and windows; then electrics; then the floor; and the door last, so it isn't knocked about by the work. Insulation goes in before the walls are finished if the garage is to be heated.

How much is a new garage door?

A manual up-and-over door costs €800 to €1,500 fitted. An electric roller door is €1,200 to €2,500, an insulated electric sectional door €1,500 to €3,000 and an electric double door €2,500 to €5,000. Taking the old door away adds €120 to €300, and a motor added to a manual door €250 to €600.

How much does a garage roof cost?

Stripping and re-covering a single garage's flat roof costs €1,800 to €3,500. On a bigger roof it's priced per m²: felt €55 to €90, EPDM rubber €70 to €110 and fibreglass €75 to €120 per m², so a double garage roof of about 36 m² comes to €2,000 to €3,250 in felt.

Is my garage roof asbestos?

Corrugated or flat fibre-cement sheets on a garage built before 2000 may contain asbestos: Ireland banned asbestos products from 1 April 2000. Left alone and in good condition they're low risk. Don't cut, drill, sand or power-wash them: have a sample tested, and have them removed by a specialist contractor.

Do I need planning permission to renovate a garage?

Under the 2026 exempted development rules, garages and sheds at the side or back of a house don't need planning permission up to 30 m² in total, if they're not forward of the front wall, leave 25 m² of the garden, match the house where they're seen at the side, stay under 4 m with a pitched tiled or slated roof (3 m otherwise) and aren't lived in. Renovating a garage you have needs no permission at all.
