How much cooler will my house actually get?

Nobody honest can answer that without measuring your roof first — and anyone who quotes you a temperature drop before seeing the substrate is guessing. What we can tell you: the stocked Roof Coat publishes 0.88 initial solar reflectance and 0.74 reflectance at three years. The EPA confirms cool roofs can stay up to 60°F cooler at the surface and cut peak cooling demand 11–27%. Your roof file tells us what that means for your house specifically. The assessment is free.

Is this just expensive paint?

If it were paint, we would sell it at the hardware store and skip the roof review. Paint is pigment in a binder. Sundown specifies a ceramic microsphere system to a film thickness, applies it over a substrate-matched prep sequence, and verifies it against published radiative values most coatings never disclose. The difference shows up at three years — when paint has chalked and the stocked coating still reads 0.74.

Will it fix my leaking roof?

No — and we will tell you that before you spend a dollar. A coating is not a repair. Soft decking, trapped moisture, and active leaks get resolved first, because sealing over a wet assembly makes the problem worse and harder to find later. If your roof review shows structural issues, we will say so plainly and recommend the right fix before any coating is specified.

How much does it cost?

Roof Coat is $445 a five-gallon bucket, $420 each for two or three, $395 for four to nine and $370 each on a pallet of ten or more, plus ground shipping shown by region before you pay. Clear Coat carries the same ladder and goes only over our Roof Coat. Managed installation is quoted after the roof review because gallons follow your measured square footage — not a generic size chart. We publish the bucket price because you deserve to know the number before a sales call, not after, and any order can be split over months through Affirm, Klarna or Afterpay at checkout.

Can I really do this myself?

Yes, if the roof file qualifies for that path. The kit ships with the specified Roof Coat path, compatible sealant, exactly two rolling pads, and a Sundown Application Guide with step-by-step instructions. It does not include a roller assembly or extension pole. Clear Coat is optional, not the default. If your roof review reveals conditions that need professional hands, we will tell you that honestly and recommend the managed path instead — we would rather lose a kit sale than have you on a roof that needs a pro.

Is Clear Coat a clear polyurethane finish?

No. Clear Coat is not urethane or polyurethane. It is the same ceramic base used in our Roof Coat with the white pigment left out. The ceramic content can still look slightly cloudy on a bare surface, so Clear Coat is not a stand-alone gloss and is specified only as the add-on layer over our Roof Coat.

What happens when it weathers?

Every coating loses reflectance over time. The difference is whether the brand publishes that number or hides it. The producer publishes a three-year aged reflectance of 0.74 alongside the 0.88 initial value. Both numbers sit on the evidence page because a brand that only shows day one is showing the easy half of the record. Ask the last guy where his three-year number is.

Why should I trust you over the big-box brands?

Because we publish what they won’t. Every claim on this site links to a source — producer data sheets, CRRC listings, or EPA references. We show you the three-year number, not just day one. We measure your roof before quoting, not after. And both founders live under roofs coated with the same system. If that is not enough, the evidence room is open — go look.

Who is behind Sundown Coatings?

Robert Yeager and Greg Tomsik — two owners, not a franchise. Robert runs platform and go-to-market from Redding, California. Greg holds California contractor license 586698 and has been coating roofs since 1999. They use the stocked Roof Coat on their own homes, and they answer the phone when you call.

88% reflected. Published, not promised.

Your roof is cooking your house. We stop it.

Your roof takes the sun all day and hands it down through the ceiling. Sundown changes the surface: 0.88 reflectance on day one, still reading 0.74 at three years.

Get my free roof assessment Watch the science

Before we talk about coating anything

Which room did you give up on?

Nobody wakes up wanting paint.

You are here because the fan, the blinds and the service call did not fix it.

“That back bedroom is unusable after two.”

So the door stays shut and it holds boxes now.

What is a room you cannot use worth over three more summers?

“The AC runs all afternoon and never catches up.”

A bigger unit against the same heat load is a bigger bill doing the same losing.

What did the service calls change about four in the afternoon?

“My bill triples in the summer and I just eat it.”

Pull twelve months of statements. The June-to-September gap is cooling.

How many more summers do you plan to pay that gap?

“It is still hot in here at nine at night.”

The sun went down three hours ago and the house has not let go of the day.

No thermostat setting reaches heat that is already in the structure.

Four complaints, one cause

The heat is coming from overhead.

The pain

The roof is the burner.

A dark surface soaks up sun all day and hands it down through the ceiling.

The fix

Change the surface.

Ceramic coating sends most of that sunlight back up before it becomes roof heat.

It is still there in year three.

Buckets, and the guide that goes with them.

Five-gallon buckets of Roof Coat, white, and optionally Clear Coat to go over it. Nothing else is in the box. The written application guide, with prep, coats and cure for every qualified substrate, is published free at sundowncoatings.com/guideand linked from your order confirmation. Rollers, pads and sealant are hardware-store items and the guide names the spec. There is no one-gallon can.

Any order can carry the surface the building actually needs.

Roof Coat for roofs. Wall Coat for walls. Marina + Stucco Coat carries grit for wet walking surfaces. Clear Coat is the ceramic base without the white pigment and goes only over our Roof Coat.

Three ways into the system

Three doors. Your roof picks one.

Managed installation is quoted from the measured roof, so no headline number is built on the wrong count of gallons.

The arithmetic

Priced from the roof, never from a chart.

Gallons follow measured area: about 32 finished square feet per gallon on flat, about 75 on sloped, over two to three coats.

Why the kit price waits

Measured roof areaLength times width, verified on site
Released coverage rateSquare feet per gallon, set by the formula owner
Wet film targetThickness the system is rated at
Material quantityThe output, never a generic size chart

A low headline price built on the wrong number of gallons is not a deal. It is a failed roof with a deposit attached.

Published, not extracted

One price ladder we print. One job we measure.

Five-gallon buckets. No one-gallon cans.

How many buckets you need comes off the measured roof, not off a size chart.

Roof Coat, 5-gallon bucket

$420 each for 2 to 3, $395 for 4 to 9, $370 on a pallet of 10. Plus ground shipping, shown by region at checkout.

The white ceramic coat

0.88 solar reflectance out of the bucket, 0.74 at three years. About 32 sq ft per gallon finished on a flat roof at two to three coats. The written application guide is linked from every order confirmation.

Clear Coat, 5-gallon bucket

The harder top build

Clear Coat is not urethane. It is our ceramic base with the white pigment left out, so it goes over our Roof Coat and nowhere else.

Both discounts stack with pay-over-time. Ask when you start the roof file.
