"just don't skip on ventilation, that's key."
Good point on ventilation, but I'm wondering if reflective coatings alone are really enough? I've heard mixed things—anyone tried just adding extra insulation instead? Seems cheaper and might give similar results... thoughts?
Reflective coatings can help, but honestly, I wouldn't rely on them alone. They're great for bouncing sunlight away, but insulation tackles heat transfer directly—so they're kinda doing different jobs.
"Seems cheaper and might give similar results..."
Cheaper upfront, yeah, but insulation effectiveness depends a lot on your climate and roof type. In my experience, extra insulation is fantastic in colder areas or places with big temperature swings. But if you're somewhere hot and sunny most of the year, reflective coatings combined with proper ventilation might actually be more effective at keeping indoor temps down.
I tried just beefing up insulation once (thinking I'd save money), and it helped some...but the attic still got pretty hot in summer afternoons. Eventually added a reflective coating anyway, and that made a noticeable difference. So maybe it's not an either/or thing? Curious if anyone else has had similar experiences...
Yeah, totally agree with the insulation vs reflective coating points. I've inspected plenty of attics where homeowners went heavy on insulation thinking it'd solve everything, but without proper ventilation or reflective barriers, the attic still turned into an oven by mid-afternoon. Reflective coatings definitely help bounce off radiant heat, but they're not magic bullets either—gotta have that airflow too. Honestly, best results I've seen usually come from a combo approach...and maybe a cold drink or two while you're at it.
"Reflective coatings definitely help bounce off radiant heat, but they're not magic bullets either—gotta have that airflow too."
Exactly right. I've seen buildings with top-tier reflective coatings still struggle because the attic ventilation wasn't properly planned. Curious if anyone's tried ridge vents versus turbine vents and noticed a significant difference in attic temps?

I've installed both types on different projects, and honestly, the difference isn't always night and day. Ridge vents are great because they're passive—no moving parts, less maintenance—but they rely heavily on proper soffit ventilation to create that airflow. Turbine vents, on the other hand, can move a lot of air when there's wind, but they're pretty useless on calm days. I've seen turbines seize up after a few years too, especially cheaper models.
One thing to keep in mind is your local climate. If you're somewhere with consistent breezes, turbines might actually outperform ridge vents. But if your area is calm or you're worried about aesthetics (some homeowners just hate the look of turbines spinning up there), ridge vents might be a safer bet.
Has anyone here experimented with combining both types on the same roof? I've heard mixed opinions about whether that's beneficial or just redundant...
