Danish homeowners with asbestos roofs face limited options as removal deadline looms

Homeowners in Denmark with asbestos roofs have few viable alternatives to full removal, according to building experts, as financial constraints and upcoming regulations complicate repairs, DR reports.

The most effective solution remains complete removal, said Tue Patursson, a construction consultant at Bolius, a Danish building advisory centre. With an average lifespan of 50 years, most asbestos roofs installed in the 1960s–80s are now deteriorating, risking the release of cancer-causing fibres.

“There really are no good solutions if you can’t afford full replacement,” Patursson said. Up to 400,000 Danish homes still have asbestos roofs, many in rural areas where financing options are limited.

Temporary fixes carry risks

For those unable to fund removal, alternatives include professional cleaning and painting—though this becomes illegal after 1 July, when high-pressure washing of asbestos roofs is banned. DIY cleaning with a soft brush remains permitted, but Bolius notes no independent evidence that this extends a roof’s lifespan.

Another option is overlaying the asbestos with a new roof, though Patursson warns this merely delays the problem. “We don’t eliminate the risk, and we lose visibility if fibres start crumbling into attics or neighbouring properties.” Overlaying may also hinder firefighting efforts and could be invalidated by future regulations.

Inaction poses health hazards

Doing nothing is the least advisable choice, Patursson stressed, as ageing roofs risk spreading fibres via wind or rainwater. “These roofs are past their lifespan. The fibres can contaminate soil, drains, and even neighbouring properties.”

With no government subsidies or tax incentives currently available, homeowners face a dilemma: invest in full removal or accept temporary, imperfect solutions.
