Asphalt shingles- 30 yrs. (only about 15 yrs. of life, though). Tin- 50-100 yrs. You do the math. Tin is way more expensive, but usually works out to save you over the life of the roof (longer than yours). For Canadian weather, I'd strongly recommend the tin as it sheds snow/rain better. Oh, I'm thinking NW Canada, not sure where you live, but still, tin is the better material all the way around.
It is not easily installed on a hip roof. Steeper roof pitches make installing metal roofing more time consuming, due to safety constraints. On a gabled end roof, metal roofing will go Much faster. providing that the pitch is not much more than 4/12.A lot faster. I installed a steel roof on a 30x50 7/12 gabled end today, and had time to drink beer, and eat oysters.teeper roof pitches make installing metal roofing more time consuming, due to safety constraints.
