Can you put solar panels on an asbestos roof?

No, and any installer worth hiring will tell you the same. You cannot drill, screw or load an asbestos cement roof without releasing fibres and risking the sheets, so the panels cannot be fixed to it. That leaves two real routes: take the asbestos roof off and install on the new one, or ground-mount and leave the roof out of it. Here is how each works, what it costs, and what the grants actually pay for.

No
SEAI solar grant (homes, 2026)
Up to €1,800
Farm route
TAMS: 60% roof + 60% solar

Why installers refuse the roof

Three separate problems stack up, and any one of them would be enough.

  • Fixing means drilling. Solar mounting rails are anchored through the roof covering into purlins or rafters. Drilling or screwing through asbestos cement releases fibres, which is precisely the disturbance the asbestos regulations are written to prevent. Since the 2025 rule changes, the default where work would disturb asbestos is removal first, not working around it.
  • The sheets are fragile. Asbestos cement was never designed for point loads, foot traffic or racking. Fragile roofs are one of the most persistent causes of serious falls in Irish farm and construction work, and an install crew cannot do their job without being on the roof.
  • The timelines make no sense together. Panels are typically warranted for 25 years or more. Most Irish asbestos cement roofs went up before the 2000 ban and are already at or past the end of their design life. Mounting new panels on a roof that will need replacing mid-warranty means paying to take the array off and put it back on again.

The practical consequence: Irish installers respond by refusing the roof, not the job. The two answers you will actually be offered are a roof replacement first, or a ground-mounted array.

The €1,800 claim, corrected

You may read online that homeowners can "receive up to €1,800 if removing asbestos to install solar panels". That sentence puts two unrelated things together. The €1,800 is the standard SEAI solar electricity grant, the 2026 maximum for a domestic PV installation. It is paid for the panels, on homes built and occupied before 2021, whether or not asbestos was ever involved.

SEAI does not fund asbestos removal. Not as a line item, not as enabling work, not within any retrofit measure. If your solar project requires an asbestos roof to come off first, the removal and the new roof are yours to fund, and the grant applies only to the install that follows. The grants guide covers the indirect routes (Croí Cónaithe for wider refurbishments, local authority schemes) that can absorb asbestos cost inside a bigger project.

Route 1: remove, re-roof, then install

For a house, garage or commercial building, the sequence is three trades in a fixed order.

  1. Asbestos contractor. Strips and disposes of the sheeting under the permit rules that apply to the job. Reported figures: about €1,200 to €4,500 for a small shed or garage roof, €3,000 to €8,000 for a typical farm shed. See what asbestos work costs.
  2. Roofer. Fits the replacement covering. This is the reinstatement cost that asbestos quotes leave out, and on a roof it can match or exceed the asbestos line.
  3. Solar installer. Installs on a sound, modern roof, with the SEAI grant applying to this stage for eligible homes.

Route 2: the farm case, funded twice

Farm sheds are where solar meets asbestos most often in Ireland, and they are also where the funding is strongest. Two TAMS measures apply, each at 60%:

  • The roof: the TAMS Farm Safety re-roofing measure pays 60% of the cost of replacing a shed roof, within the standard €90,000 investment ceiling. The asbestos removal itself is not an eligible item; you fund the strip-out, the grant aids the new roof. Full detail in the TAMS roof grant guide.
  • The solar: the TAMS Solar Capital Investment Scheme pays 60% towards on-farm solar PV, and its €90,000 ceiling is ring-fenced, so it does not eat into the allowance the re-roofing draws on.

Sequenced together, an ageing asbestos shed roof becomes a grant-aided modern roof carrying grant-aided generation, with the asbestos strip-out the only wholly unaided line in the project.

Route 3: ground-mount and leave the roof alone

A ground-mounted array takes the asbestos roof out of the solar decision entirely, which is why installers themselves propose it where the covering is asbestos cement and the site has space. It does not make the asbestos question disappear: the roof is still ageing, still fragile, and still yours to deal with eventually. But it lets the solar project proceed now and the roof be dealt with on its own timeline. Weigh the ground it occupies against the cost of bringing the roof replacement forward.

Frequently asked questions

Can you put solar panels on an asbestos roof?

No. Solar mounting systems are fixed through the roof covering into the structure, and drilling or screwing through asbestos cement releases fibres, which is exactly what the asbestos regulations exist to prevent. Asbestos cement sheets are also fragile and were never designed to carry point loads or foot traffic, and most are decades into a design life the panels would outlast twice over. Installers deal with this by refusing the roof, not the job: the standard answers are remove and re-roof first, or ground-mount the array.

Is there a grant for removing an asbestos roof to install solar panels?

No. You may read that homeowners can "receive up to €1,800 if removing asbestos to install solar panels". The €1,800 is simply the standard SEAI solar electricity grant for the panel installation itself (the 2026 domestic maximum). SEAI does not fund asbestos removal or any enabling work; the asbestos line is yours to pay. See our grants guide for the indirect routes that can absorb it.

What does it cost to replace an asbestos roof before going solar?

Reported Irish figures for the asbestos side: about €1,200 to €4,500 to strip and dispose of a small shed or garage roof, and €3,000 to €8,000 for a typical farm shed, before the new roof and before the solar install. House roofs are quoted per job. See what asbestos work costs and what drives removal pricing.

Can farmers get grants for solar on an asbestos shed?

This is the strongest funding case in the country, in two halves. TAMS pays 60% towards replacing the shed roof (Farm Safety re-roofing measure, within the €90,000 investment ceiling), and the TAMS Solar Capital Investment Scheme separately pays 60% towards on-farm solar PV with its own ring-fenced €90,000 ceiling. The asbestos removal itself is not an eligible item in either scheme. See the TAMS roof grant guide.

What about ground-mounted solar instead?

A ground-mounted array avoids the asbestos roof entirely, which is why installers themselves suggest it where the roof is asbestos cement and the site has space. The asbestos question does not go away (the roof is still ageing and still yours), but it stops being coupled to the solar decision. Weigh the space it takes against the cost of bringing the roof replacement forward.

How do I know the roof is actually asbestos?

Corrugated cement roofs on Irish buildings put up before 2000 should be treated as asbestos cement until tested; similar-looking asbestos-free fibre cement only took over after the 2000 ban. A single sample through a test kit with accredited lab analysis settles it before you price anything. See identifying an asbestos roof.
