Hi, just wondering if anyone has dealt with this situation before. I have an overhead line that is above a covered patio and shed. I know the clearance above roofs is supposed to be 8ft. But I don't see how this is possible here. I've posted some pictures as well.

Read the exceptions to 230.24(A). You need 8 1/2 feet of clearance over the roof to from the edges to 3 feet in.
Exception 2 drops that to 3 feet for a <300V service if the roof has a pitch of 4 and 12 or steeper. Probably won't help you but maybe for the shed?
Exception 3 drops that to 18" for a <300V service if you terminate at a mast or through the rood raceway within 4' of the edge of the roof. That covered porch looks longer deeper than 4' but maybe the wires are angled and only cross a portion of the roof?.
Exception 4 lets you ignore the clearance requirement from edges to 3' in of the roof if the conductors are attached to the side of a building. This may apply to the covered porch, but it could have been better if the service drop was anchored higher on that building to get as much clearance as possible (although that would have brought it in further which makes it cross more roof.
Exception 5 drops the clearance to 3' for a <300V service if the roof is guarded or isolated. That may work for the shed depending on what is met by isolated.
 
Yeah, I didn't measure the roof pitch but idk if it's 4in in 12in. Hoping someone has had this happen before. There's really no way to get the line up to 8ft above the shed.
 
I would agree to relocating the point of connection higher up on the gambrel roof, extend the service conductors up to the new point of attachment and the clearance should be fairly close based on picture. It is hard to tell if the current point of attachment is laying on the current roof
 
I dont think the NEC applies to service drops exclusively installed, owned and maintained by the utility.
Its probably different in different states, but have a look at Article 90.2(D)(a)
I'd say that it falls under the NESC.
