The reality here is that hailstorm or straightline winds are more likely to get it before it makes it that far... I wish you luck here if you believe you will make it 50 years without having a bad hailstorm or windstorm here at some point...
The flip side, without the weather, I've seen 3 tab roofs up north, where the winters are colder, but the summers not quite as hot, last 35+ years with no issues, despite the rating being 20 years.

Yes the angle the summer sun strikes a roof can be a huge factor and how long shingles last. Metal is taking over in these parts even in more upscaled areas due to life expectancy. Around here on metal the seals go after around 40 years and it will need to be re-screwed but there is no down time as in no roof replacing done.
