Did you take into account the 30% federal tax credit on that 30k?
EDIT: That's sort of the kicker. A regular roof does not get a 30% federal tax credit (plus possible state incentives), nor does it produce power for 30+ years, nor does it have a lifetime warranty. If you can obtain low cost financing, you almost always come out ahead.

Maximizing retirement savings is still likely more cost effective than this roof for most people and I doubt many people in the US are putting away $24k/year.
The only way I'd see this is as viable is below inflation interest and people showing they can sell the houses for the full value of the Tesla roof.

If I understand the tax credit correctly, it's only available if you're paying that much in taxes otherwise. For a $60k roof, you have to already be paying $18k in taxes to take full advantage of the credit. That's an important detail for some.
