Questions people ask
How much does a new roof cost in Ireland?
On a two-storey semi, €8,500 to €15,000 in concrete tile, €9,000 to €17,000 in fibre cement slate and €16,000 to €24,000+ in natural slate. A detached house is €11,500 to €32,000+. The cost guide breaks it down by house, material and county.
Why do roof quotes vary so much?
Because they often price different jobs. One includes new battens, a breathable membrane, lead flashings, scaffolding, the skip and VAT; another leaves half of it out. The company we pass you to puts every item in writing, so you can see what you're paying for.
How long does a new roof take?
Three to ten working days on most houses, weather allowing, plus a day either side for the scaffolding. The roof is made weather-tight every evening. See how long it takes.
Is there a grant for a new roof?
Not from SEAI for the roof itself. The council's Housing Aid for Older People grant can pay towards repairing or replacing a roof, and the Vacant Property Refurbishment Grant covers roof work on a vacant house. See grants and VAT.
