Yes it is, really depends what type of arc you are looking at and what your location is. For me in the South of the UK, my arc, 45 degrees either side of due south, has a lowest elevation of 18 degrees, but the majority of the satellites I look at are 25 degrees or above. so for every 2 metres away from the apex of the roof, I gain just over 1 metre in clearance.
