I am hoping to run electrical wires in my exterior walls, but I have a very low pitched roof which makes it tough to get to that part of the attic. To give some examples:
One of my switches does not have a neutral wire, I'd like to run a 14/3 wire from the light to the switch to bring the neutral to the switch.
I only have one exterior light by my garage door (on one side of the garage), and I'd like to install a matching set of exterior lights, one on each side of the garage door, to better illuminate the driveway at night.
One of my bathrooms is near an exterior wall, and I want to rewire the switches so that the lights operate in a way that makes more sense. An electrician installed an extra can light, by tying it into the fan, rather than the same switch as the over-vanity light, leaving me with a situation where one switch has a light; and the other switch has a light and a fan. I'd like to adjust this so the lights are on one switch circuit, and the fan is on the second switch circuit. This isn't actually in the exterior wall, but just off of it, so it's the same problem of getting physically into the space.
This may seem like multiple questions at once, but the problem is actually all the same: Of course, it's tough to run wire through the exterior wall if I can't get physical access to the part of the attic. There just isn't the space for a human body to get in there.
So what is the solution? Is there a way to run electrical wires to a location in an exterior wall when you have a low-pitched roof? Or am I stuck with what I've got?
