Should I buy a leaky condo?

Lately I've been recieving a lot of mail asking for advice on specific issues.. I'd like to take this time to proclaim my non-expert status. I have no way of foretelling the future, if I had that ability I'd be too busy swimming around in my money bin to post here.

The most recent question to come in is from someone considering the purchase of a previously leaky condo unit that has been repaired and has the standard warranty. Here's the concern:

"The development is in Coquitlam and was repaired last year to a level that it has the 2-5-10 warranty. My concern is in the design of the building which doesn’t have overhangs in some areas and has a flat roof in some areas. Should I be concerned with this?"

Most conventional wisdom I've heard says to stay away from buildings like this, but I have a feeling that some of the people reading here might know more about this subject than I do, so therefore I submit this topic for discussion - Are flat roofs and lack of overhangs on a repaired leaky condo a dangerzone? Or are previously leaky condos a good way to get into an overpriced market?
