You’ve got questions, we’ve probably had the same ones. Here are the most common things people ask us about heat reflective paints, how we review them, and what to do if you’re stuck with one that doesn’t seem to be doing the job.
Yes. 100%. If there’s a product you want us to look into, just send us the brand name or manufacturer details. We’ll contact them directly, hunt down the specs, and let you know once we’ve posted a review. You can contact us here to get that started.
Good question—and the answer depends on a few things. If you suspect your coating isn’t pulling its weight, we can help you dig into it. Send us an email with as many of these details as possible:
We’ll help you figure out what’s going on—or at least point you in the right direction.
We’re not here to crown a winner. That’s not how this works.
What we don’t do:
We don’t hand out gold stars or declare a single “best” product. Paints perform differently depending on your roof type, location, colour, and even how they’re applied.
What we do offer:
Real, comparable information. Head over to the Compare Brands page. There, you’ll see each brand broken down by specs, claimed performance, and SRI. You decide what fits your project—not us.
Still stuck? Send us your situation, and we’ll try to add the info you need across all the brands we cover.
Yes. A lot.
Colour has a huge impact on reflectivity—lighter colours naturally bounce more sunlight, while darker colours absorb more heat. Even with a reflective coating, a deep charcoal roof will never perform like a white one.
That said, some high-SRI paints do a decent job even in mid-tone colours. Just don’t expect miracles if you’re coating a black tin roof in “cool grey.” Check the SRI and compare.
Nope—and this one really matters.
Heat reflective paints stop heat before it gets in. Insulation slows it down after it’s already inside. Think of reflective paint as sunblock, and insulation as a thick jumper. They do different jobs, and one can’t replace the other.
Plenty of paints claim to insulate, but unless they’re physically thick and rated for thermal resistance, that’s just clever wording.
Because the number wouldn’t help them sell it.
If a manufacturer doesn’t publish the Solar Reflectance Index, it’s usually because it’s not impressive. SRI is one of the few hard metrics that tells you how well a paint actually performs. Without it, you’re relying on adjectives and hope.
Always ask for the SRI—or move on.
