Replacing Support Above a Doorway With UPVC Door and Frame information and advice on general building topics, builders merchants, problem builders, DIY Stores etc....

Hi our back garage door frame seems to support one of the beams / joists of the flat roof , I am now wanting to replace the door and frame with upvc . Will this still be suitable for supporting the joist ? Or would I need to put some extra support in ? If so what would be best ?
