Great suggestions here, especially about the reflective shingles. Hadn't really thought about those before, but it makes sense they'd help with heat issues. I'm definitely leaning toward synthetic composite shingles myself—metal sounds awesome, but the quotes I've gotten so far are pretty steep.
One thing I'm still unsure about though is lifespan vs. cost. I mean, composites seem durable enough, but do they really hold up as long as metal or traditional shingles? I've heard mixed things from friends who've gone composite—some swear by them, others say they start looking worn sooner than expected. Maybe that's just brand-specific or installation-related though...
Has anyone here had composite shingles for a good 10+ years now? Curious how they're holding up over time compared to other materials.
