Minnesota weather can be tricky.

So tricky that it has caused problems with the Minnesota Vikings' new stadium, that's scheduled to completed in time for the 2016 season. According to the Minneapolis Star-Tribune, the snow gutter on top of US Bank Stadium has started leaking and will need to be repaired.

The cost of fixing the leak? A cool $4 million, M.A. Mortenson Co. executive John Wood said on Friday. That seems like a lot until you consider the price of the stadium comes in at $1.1 billion.

Per the Star-Tribune:

The replacement work will affect about 30 percent of the facade, most noticeably on the large eastern face where the black panels will need to be taken down. In doing so, workers also will temporarily remove the white U.S. Bank Stadium logo, Wood said.

As many homeowners know, finding the source and path of leaks is tricky. Wood said it took months to diagnose the problem and determine a suitable fix.

The cause of the leak was a faulty vapor barrier on one side of the building that was will be replaced with new material. The three other sides of the building had yet to be installed, so they won't need to be replaced.

The good news is: The cost of the repair won't be charged to the taxpayers, Vikings or the Minnesota Sports Facilities Authority. Wood says his company and the design team will foot the bill.

US Bank Stadium is still on schedule to open in August.
