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.
The average materials and prices for this project would include: 1  Contractor: the cost of a tin roof installation on the home described above would be $5700. This includes the use of new plywood 1 sheathing but not the removal and disposal of pre-existing materials - which tends to bump up costs around $3 per square foot.
