- When we switched from darker to lighter shingles, attic temps dropped a bit, but honestly, the utility bills didn’t budge much.
- Biggest impact came after adding more soffit vents and a ridge vent.
- Curious if anyone’s tried those solar attic fans—worth it, or just another thing to maintain?
I tried a solar attic fan a few years back, mostly out of curiosity. Honestly? It helped a little with attic temps on the hottest days, but not enough to justify the cost or the hassle once it started making noise. Like you, I saw way more of a difference after adding proper ventilation. Lighter shingles look cooler on paper, but in my case, the vents did the heavy lifting. If you’re in a super sunny spot and don’t mind the extra thing to maintain, maybe it’s worth a shot... otherwise, I’d just focus on airflow.
- Totally agree, the solar fan didn’t move the needle much for me either.
- Spent less on adding ridge and soffit vents, got way better results.
- Lighter shingles might help a bit, but I’d say airflow is where your money goes furthest.
- Maintenance on those fans is just another headache... not worth it unless you’re desperate.
Malarkey’s a solid shingle, but if your main goal is to keep the attic cooler, I’d focus way more on airflow than shingle color or brand. I get the appeal of those “cool roof” options, but honestly, I swapped out my old black shingles for lighter ones a few years back—barely noticed a difference in attic temps. What really moved the needle was finally biting the bullet and putting in continuous ridge and soffit vents. Way less heat buildup, and my AC actually got a break in July for once.
The solar fan thing... yeah, I tried one too. It just felt like another gadget to babysit, and it didn’t solve the real problem. Lighter shingles might help a little if you’re in a brutal sunbelt climate, but if you don’t have good ventilation, you’re just rearranging deck chairs. If you do go with Malarkey, at least you’re getting better impact resistance and some recycled content, which is a win in my book. But for attic heat, vents are king—shingle brand is way down the list.
I’m with you on the vents making the biggest difference. I geeked out over shingle specs for weeks, but after crawling around my attic in August, it was obvious the airflow was the real culprit. Swapped my old box vents for a proper ridge/soffit setup and suddenly the attic wasn’t a sauna anymore. The shingle color thing is interesting, though—I did some IR thermometer checks out of curiosity, and yeah, the lighter shingles were maybe 10-15 degrees cooler on the surface, but inside? Not much change unless the ventilation was sorted.
Malarkey’s eco-credentials are a nice bonus if you care about recycled content or smog-reducing granules (which I do), but for actual attic temps, it’s all about how fast you can get that hot air out. Solar fans always seemed like a band-aid to me… another thing to break, and not enough airflow to matter unless you’ve got a tiny attic. If you’re in a place with brutal sun, maybe the “cool roof” shingles are worth it, but for most folks, vents first, shingle brand second.
