Attic and Roof Insulation in Longford

Heat rises, and in a house with a thin or settled layer of attic insulation it keeps going straight out through the roof. Laying a proper depth of mineral wool between and over the joists is the cheapest way to stop that, and on most houses it is a job of hours rather than days.

Attic and Roof Insulation in Longford: Common Questions

How Many Attic and Roof Insulation Contractors Are There in Longford?

There are eight SEAI-registered attic and roof insulation contractors based in Longford. Every one is drawn from the official SEAI register, which is what keeps the work grant-eligible.

How Much Does Attic and Roof Insulation Cost in Longford?

As indicative market guidance rather than a price, a three-bed semi runs €700 to €1,200 before any grant, with the SEAI grant currently up to €2,000 and most homeowners left with €0 to €0. Longford being a low-lying inland midlands county on the River Shannon means access varies, and a quote should always come from a contractor who has seen the house.

Which Towns in Longford Are Covered?

The contractors listed here work across Longford, including Longford, Granard, Edgeworthstown, Ballymahon and Lanesborough. Most travel well beyond their registered address, so it is worth ringing a contractor based a county over rather than assuming they will not come.

Is My Longford Home Suitable?

Older solid block and stone across the rural stock, with limited modern cavity development. If you can get into the attic and see the joists, it is the cheap job, and it is almost always worth doing. The question is usually not whether to insulate but whether you are topping up or starting again, since an attic that looks insulated from the hatch is frequently insulated to a third of what it should be.

How Is the SEAI Grant Paid in Longford?

Through a One Stop Shop the grant comes off the price upfront. Apply yourself and you pay in full, then SEAI pays you back once the work is signed off. The grant for attic and roof insulation is up to €2,000, checked against SEAI on 31 July 2026. It works the same way everywhere in the country, so there is nothing specific to Longford beyond choosing a contractor on the SEAI register, which every contractor on this page is.
