@AnotherEngineer good point.
I also question the "luxury" of living in a place where 3 week power outages and washed out roads are the norm. That has never been Western NC, but it is all of Florida, much of Louisiana, and much of the Texas coast.
@NorCal I agree. As a whole society, we are vigorously pursuing tiny benefits or tiny cost savings that make no economic sense in the longer run. Regarding your roofing observation - why can't we have the sort of tile/slate/ceramic roofing that is common in Europe?
The costs are not that obscenely higher for materials that last 4x as long, are strong enough to resist a routine hailstorm, and which might save hundreds of dollars per year in insurance costs*.
And Americans are gravitating toward building houses even more cheaply and disposably. Today I learned that some tract home builders are using a
literal cardboard material as exterior sheathing to save a few dollars per sheet. If anyone is under the illusion that building codes are designed to protect us, tell me more about how your cardboard house is going to work in 25 years.
*A possible explanation for why we don't build more durably is that U.S. insurance companies are bad actuaries. For example, if I had a tile roof instead of asphalt, it would actually
increase my premiums because the replacement cost is higher, and they might disregard the much lower odds of replacement due to a hail or wind storm. Perhaps there are not enough houses with various types of roofing for them to accurately calculate risk, so they just anchor on the asphalt numbers? IDK.
Metal roofs should be code. There's no reason to put a shingle roof on a house that I can think of.
My house has a steep roof pitch. It is sketchy to walk/crawl across with asphalt shingles so metal would be deadly when it comes time to inspect or do maintenance.
