That's a pretty practical way to narrow things down. I remember inspecting a house a few summers back where the owners had switched from dark gray shingles to a lighter beige. They mentioned noticing a real difference in attic temperatures afterward—nothing drastic, but enough to make the AC run a bit less often. Like you said, it's not going to replace good insulation or proper venting, but every little bit helps, especially if you're already planning on replacing the roof anyway.
"They mentioned noticing a real difference in attic temperatures afterward—nothing drastic, but enough to make the AC run a bit less often."
Fair point, but honestly, I'd be cautious about attributing too much to roof color alone. I've inspected plenty of homes where owners made similar claims, but when you dig deeper, other factors usually play a bigger role—like improved attic ventilation or sealing air leaks. Sure, lighter shingles might help a bit, but in my experience, the difference is often overstated. If energy efficiency is your main goal, I'd prioritize insulation upgrades or better venting first. Roof color is more about aesthetics and curb appeal than meaningful energy savings... at least from what I've seen.

Gotta mostly agree with you there. I've had customers swear their lighter shingles made a huge difference, but when we checked things out, usually they'd also upgraded insulation or venting around the same time. Roof color alone? Meh... maybe a small nudge in the right direction, but nothing game-changing. If you're serious about keeping your attic cool, ventilation and sealing leaks are where it's at.
We went with a lighter roof color a few years back, mostly because my wife liked the look better. Honestly, I didn't notice much difference in our energy bills afterward. But when we finally got around to adding some extra insulation and sealing up a few gaps around the attic hatch, that's when things really improved. The upstairs bedrooms stopped feeling like ovens in July, and our AC wasn't running constantly anymore.
So yeah, roof color might help a tiny bit, but from my experience, it's definitely not the main factor. If you're on a tight budget (like we were), I'd say put your money into insulation and sealing first—way more bang for your buck there.
Interesting you mention that insulation made such a noticeable difference. We just moved into our first home last year, and the upstairs bedrooms were unbearable during summer—like, seriously miserable. At first, I thought it was just because heat rises, but then I started poking around in the attic and realized the insulation was super thin and patchy in spots. So we bit the bullet and added some blown-in insulation ourselves (which was an adventure, let me tell you...).
Anyway, after doing that, we noticed a huge improvement. The AC wasn't kicking on nearly as often, and the upstairs rooms actually became comfortable enough to sleep in without fans blasting all night. But here's the thing—I haven't even considered roof color yet. Our shingles are pretty dark, and now I'm wondering if going lighter would have made any difference at all, or if it's mostly just aesthetics.
Did you notice any other benefits from the lighter roof color besides energy savings? Like maybe less wear and tear from sun exposure or something? I'm curious if there's more to it than just temperature control.
