Two indoor sports facilities’ roofs collapsed Thursday morning after heavy snowfall earlier this week — Topsham’s Dome at Coastal Maine Storm and Mahaney Sports Dome at the University of Maine in Orono.

Owners of the Topsham facility shared the news in a Facebook post.

“Our old Dome came down early this morning due to the snow and then rain,” dome officials wrote in a Facebook post. “Sorry to say that it looks to be irreparable. Working on assessing things now. For any groups scheduled in the dome, please reach out to me later to work on refunds.”

The inflatable sports training facility rents out field space for baseball, softball, lacrosse, field hockey, rugby and more so teams can practice through all seasons.

In 2020, program director Brendon Augustine founded the Coastal Maine Storm, a travel baseball league. A year later, the Storm took over the lease of what was then known as the Dome in Topsham.

Patrons were saddened by the news but showed their support on social media, refusing any refund.


“Terrible news. You can keep my money for all the joy, commitment, and time you have given the kids. I appreciate you and the programs you have offered,” wrote Ben Dauphinee.

Messages left for the dome’s owners were not returned Thursday.

The dome collapse at UMaine came just hours later, according to News Center Maine. No injuries were reported.

That dome was built in 2006 for student-athletes to use. In 2021, the university announced a plan to replace the dome with a brand-new structure “complete with the latest upgrades and first-rate materials” with a 25-year life expectancy, according to the university’s website.

Two significant snowstorms followed by heavy rain and icing Wednesday night have caused concern about snow weight on other structures as well. Both Walmart and Sam’s Club in Scarborough closed early Thursday morning, concerned about structural soundness of their flat roofs following this week’s weather, according to WMTW.

Fire officials told the news outlet the roofs were built to withstand a lot of weight, but the drainage systems may have become overwhelmed by the volume of snow and rain.

Both businesses are scheduled to be inspected before reopening to the public, according to WMTW.
