If you can stretch to rubber, and look to be in the house for a long time, deffo do it.
My builder uncle will never touch felt, it always fails and needs much more maintenance than the alternatives. It’s especially prone to heat damage, which will only get worse with more frequent heatwaves.
Yeah, having done a rubber roof on my garden office I'm edging to that but less people who do it vs felt and there's going to be a couple of windows and a couple of pipes (extraction etc ...) exiting the roof so these bits tend to be a bit tricky.
