I have painted 15 or so narrowboats completely and 50 or so partially.
Although i can paint a roof alone it is far better to have 2 people,1 each side.
I can use just a brush or roller and brush.
However i have never painted a widebeam [12ft] roof.
If you have to work outside,how the hell do you keep the edge wet lol.
I assume a 7/9" roller and 4"+ brush and maybe an extension handle.
Has anyone any tips or should i learn the hard way lol.
I may section the roof off but my friend just wants a single colour.
