Since rain apparently doesn't always extinguish lightning fires, many of my buildings are now at danger of spontaneously combusting.
Besides building solely with non-flammable materials like stone (which actually tends to make things rather ugly), what are some methods to safeguard against (or at least stall) disasters like this?
I experimented with putting a layer of water between floors so that fire is immediately extinguished as it breaks through ceilings, but the walls still burned up and I was left with a soggy mess to clean up later.

In the real world having something taller than your house is the way to do this, so in Minecraft you could build a spire next to your house.
However, unless Notch has implemented lightning "properly" you won't be able to rely on this, and your only solutions are to put something non flammable between your house and the sky or build out of non-flammable materials.
The only real alternatives to stone are brick, gold, iron (but these depend on you being able to find a lot of clay, gold ore and iron ore) and glass.
I'd try a glass canopy in the first instance.
