MINNEAPOLIS (AP) — The roof on the Minnesota Vikings' new stadium is leaking, and the general contractor says it needs $3 million to $4 million in repairs.

Mortenson Construction Vice President John Wood says stadium designers and builders will cover the cost, so it won't be added to the overall budget or cost taxpayers or the Vikings.

Wood says the water from the snow gutters isn't getting into the stadium interior, but it is getting into an outer wall where construction crews spotted it leaking out.

The fix will require a fairly conspicuous repair. Workers will have to remove the U.S. Bank Stadium sign and pull off a third of the stadium's dark metal cladding to replace a faulty moisture barrier.

Wood says it won't delay the stadium's opening.
