Totally agree about the underlayment—these days it’s a game changer for noise and temp. I’ve put on a few metal roofs where the attic stayed cooler, but only when folks went with a light color and beefed up the insulation. Anyone here ever mess with those “cool roof” coatings? Curious if they’re worth the hype or just marketing.
I’ve wondered about those coatings too—some folks swear by them, but I haven’t seen a huge difference after storms. Maybe it helps a bit with heat? I’d be interested if anyone’s actually noticed lower temps or energy bills after applying one.
We tried a reflective coating on one of our flat roofs last summer, hoping it’d help with the heat. Honestly, I didn’t notice a dramatic drop in our cooling bills, but the rooms underneath did feel a bit less stuffy during peak afternoon sun. Maybe it’s more noticeable in places with harsher sun? Still, I’m not convinced it’s a game changer for storms—seems more about heat than weatherproofing.
- Interesting you mention reflective coating. I’ve seen some places swear by it, but yeah, like you said—seems best for heat, not storms.

“didn’t notice a dramatic drop in our cooling bills, but the rooms underneath did feel a bit less stuffy during peak afternoon sun.”
- That lines up with what my uncle noticed after he rolled it on his garage roof. Not huge energy savings, but definitely less “oven effect” inside.
- Where I’m at (Midwest), most folks stick with asphalt shingles. We get more hail than crazy sun, so impact resistance matters more than reflectivity for most.
- Have you thought about adding insulation under the roof deck? Sometimes that makes a bigger difference than coatings alone.
- Curious—what’s your climate like? Wondering if anyone here in the Southwest or deep South has seen bigger benefits from reflective stuff.
- For storms, I’d probably look more at waterproof membranes or upgrading the whole roof system... Coatings seem more like a supplement than a fix.
- Anyone else try combining different approaches—like coating plus extra insulation or swapping out venting?
