Something I have noticed about my US homeowner friends is that they often seem to need to replace their roof!
How long is a roof expected to last over there because the only Brits I've ever known to replace an entire roof are those who've had some catastrophic damage from extreme weather, fire or falling trees.
@stueytheround Tar shingle on felt/tyvek/? 20-30 years with a lot of variation per weather (USA contends with all sorts). Steel aka tin roof will go 50 years or more. A couple years ago I had mine replaced (tar shingle) on a 40 year old house. The roof was 90% okay but a tree branch had punched a small hole all the way through the wood deck and a skylight had a leak (because skylights do) and I got some Biden energy efficiency money. New shingle has a 50 year warranty, fwiw.
Slate roofs last a “lifetime,” but that’s the life of a human, not the life of a house. A tarpaper flat roof maybe 5-10 years, premium materials, 30 years. Sloped roofs last longer. Terra cotta roof tiles become projectiles in hurricanes but are great in fires. Every 3rd time you replace the covering, you probably need to rebuild the wood underneath.

This is incredible to me.
Rooves last dozens or even hundreds of years here with the possible exception of thatching.
