If your friend is wanting to have the best weather resistant roofing, I would recommend metal roofs. They are the most durable, lasting for at least 3 times longer than an asphalt shingle roof. According to http://www.unioncorrugating.com/weather.html , they have the highest UL ratings for fire, wind, and impact resistance. It may cost more, but I think the value of the roof, especially in harsh weather, definitely outweighs that extra cost.

A shingle roof cost $8,000 and lasts 10 years.
A dimensional shingle roof costs $12,000 and lasts 15 years.
A tile roof costs $40,000 and lasts 40 years.
A metal roofs costs $50,000 and lasts 100 years.
In 100 years $80,000 will have been spent on shingle roofs.
in 100 years $79,000 will have been spend on dimensional shingle roofs.
In 100 years $100,000 will have been spent on tile roofs.
I don't know what how those numbers translate in the Ottawa environment.
The FLORIDA required rubber under layment mitigates the noise.
Summery: Looks greats, lasts long time.
