hi, im building an 11metre by 3meter garage, 9 blocks high from dpc to wall plate. it will have a 30degree reclaimed Staffordshire blues tiled roof. the trusses were made with a very long overhang...which initially i liked, but now im thinking it may be too much for the size of the building. id like a nice overhang....but how long? any body got any experience of this quandary?
