Home warranties: are they worth it?

[Brett Lee]

Curious what people's thoughts are on home warranties and whether they are worth it or not? We have heard very mixed reviews with some people saying that they are terrible and other people saying they're great. We had a decent experience with the home warranty years ago when our oven went out and they replaced it. I currently have a home warranty on our house that was included by the real estate agent when we bought it a year ago... Wondering what people's thoughts are on whether we should renew or not.

Our house is about 30 years old and still in the original furnace. Ideally if there were a company that a warranty would cover the roof then that would be a no-brainer so if anybody knows any leads for companies that will warranty a roof in addition to other housing components that would be great.

I appreciate any input you guys have! thanks :-)
