Janie, my daughter is having her roof, about 1600 sq. ft., replaced in B. C.
She has bought steel roofing (recommended in areas where accumulated and freezing snow at times is sufficient to crush a roof), cost about $9600. It is good material, and was delivered last fall; prices are up 20% since then. That is the good news.

Labor is extremely short; so far she hasn't been able to get a crew.
People building new homes and condos, the area is popular for winter sports, etc., are paying premiums up to 3 times normal wages for skilled roofers.
I expect the final cost to be $20,000. I hope not more. Bad news.
