Cedar: 42 years and they look like they will go another 30.
I wouldn't even try to guess what it would cost to do a new 1500 sq ft house in them.
My father grew up in a house with a slate roof, built in 1930.
House is now owned by a cousin and the slate roof is still good.
In 1984 my mother wanted to buy a newly built house with a cedar shingle roof, as were all nearby houses.
My father went along with her wishes but said many times: “Cedar shingle roof is a fire hazard and will not last long.”
In 2014 we replaced the cedar shingles because we were worried about the underlayment,
but it turned out all the original plywood was good.
Cedar shingles could have gone 5 more years, maybe slightly more.
There are still 2-3 houses in the sub-division with cedar shingle roofs, but 90% have been replaced with asphalt shingles.
4 years ago a hailstorm damaged over 20 of these new asphalt shingle roofs nearby which were replaced and paid for by insurance claims.
