Wrigleyville rooftop owners say they will use "any and all means necessary" to make sure the Chicago Cubs honor the remaining 11 years of the contract that protects their view of Wrigley Field.

The Chicago Sun-Times is reporting that the Cubs and the city of Chicago are expected to agree on a Wrigley Field renovation deal.

A few rooftops would be "minimally" affected by the addition of a JumboTron in right field and at least one more sign in left field, according to sources.

The Wrigleyville Rooftops Association took issue with the news, claiming any addition that obscures their view of the park will essentially put them out of business.

"We reserve judgment until said proposals are publicized, however we are deeply troubled that 16 small businesses were not party to talks where their contractual rights were at stake," Beth Murphy, owner of Murphy's Bleachers, said in a statement.

"Rooftop owners reserve the right to use any and all means necessary to enforce the remaining 11 years of our 20-year contract. We support a renovated Wrigley Field, but the neighborhood and its businesses should be partners in the debate as we have over the last 30 years."
