Yes but not to much effort all at once,this is the second one I've done recently,my own and my cousin's,on my own I split the roof into four separate sections on his into eight,due to the different size of roofs,this I found the easiest,I used a soft nylon sweeping brush and a light pressure after applying blaze cleaning fluid,then hosed it of,until a decent finish,,the power washer stayed in the shed.
