<P> On Sunday 8 July 2012, Andy Murray and Roger Federer contested the first Wimbledon final to be played partially under a roof . </P> <P> The roof was designed by SCX Special Projects Ltd and controls for mobilising the roof were designed by Fairfield Control Systems Ltd. and Moog who supplied the electric control system comprising electric actuators, servo motors, servo drives and closed - loop controllers . All companies undertake all the planned preventative maintenance . </P> <P> The roof's ten trusses each weigh 100 tonnes, and the total weight, including non-moving parts, is 3,000 tonnes . The total area of the roof when fully deployed is 5,200 m . The cost of the roof has not been disclosed by the Club, but is estimated at £ 80--£ 100 million . Another retractable roof is planned for No. 1 Court and due to be completed in 2019 . </P> <P> The Scoreboard on centre court is one of the more recognisable parts of Centre Court . Its present shape and layout closely reflect that of the original scoreboard installed in the 1950s, which featured manually inserted panels for player names and incandescent - lightbulb display of scores . In 1982, dot matrix scoreboards on the same layout were installed on Wimbledon courts . These were replaced in 2008 by full colour LED screens intended to provide full Hawk - Eye replays to the crowd in the stadium . </P>
