Spray Foam Roof Recoatings

Ah, polyurethane spray foam… It’s the everlasting roof, right? Well, yes… with one condition. Although it’s true that spray foam roofs are renowned for their resilience and longevity (and truly, it has no equal among roofs!) there’s another side to the coin here.

What really makes foam roofs so tough is their outer coating. That’s the secret to their long life.

The Basics of Foam Roof Recoatings

The outer coating is applied after the foam itself has been sprayed onto the roof’s surface to act as a shield against the elements. Your foam roof, if you have one, has one of these outer coatings that was applied during its installation. Hopefully it is still intact, protecting your roof and home from the elements!

Think of the outer coating of a foam roof like the hard candy shell around an M&M. The outer shell is there to protect the chocolate from things like heat, contact with other objects, etc. Similarly, your foam roof coating protects your foam roof from water, debris, foot traffic, and more.


Possibly the most important thing about the coating (especially here in Arizona!) is the fact that it is UV-resistant and extremely reflective. Since the foam itself is not UV-resistant, this hard top outer coating ensures that the harsh desert sun cannot break down or compromise your foam roof.

Recoatings are more environmentally-friendly and affordable than a complete reroof.

A fresh recoating continues to help insulate your house, saving you energy.

Recoatings help maintain your spray foam roof’s durability and protects it from the elements.

If My Roof Is So Tough, Then Why Do I Need A Recoating?

Despite how tough and resilient your foam roof is, the protective layer does eventually need to be reinforced. Under the abuse of Arizona’s desert elements, the coating begins to break down over time, and you will need to re-cover it with a new layer. Doing so ensures the infinite lifespan of the underlying foam and maximizes energy efficiency.

If you never get a foam roof recoating, you will slowly but surely see it deteriorate. Over time, little pockets will start to form on the foam where the original coating has worn out, and UV rays will enlarge the holes; making them deeper.

Because the foam degrades slowly, it could take a few years for these holes to develop into leaks. So it can be easy not to notice you have a problem until it’s too late….

This is why it’s better to get the foam roof recoating sooner than later.

So My Foam Roof Isn’t Really Everlasting?

Not so fast there…

Your foam roof can last indefinitely, and unlike other roofing materials, it won’t necessarily have to be replaced. That’s the unique advantage of foam roofing.

But, like all roofing materials, it does require a certain amount of maintenance. But it’s really not that much.

Timing is Everything

We recommend recoating your foam roof once every 8 to 10 years in Arizona. This is by far the most important maintenance aspect of your foam roof to ensure it reaches its full potential and continues to provide you with its many benefits.

Shaded Roofs Can Last Longer

Our harsh Arizona sun can negatively affect the lifespan of a spray foam roof. UV rays break down the outer coating, which will eventually need to be replaced with a recoating. With more shaded roofs, your coating has a better chance of lasting longer.

Diligent Maintenance is Key

If you are diligent to recoat in a timely and responsible manner, you can rest assured that your foam roof will outlive you, your children, and your children’s children!

When Should I get a Foam Roof Recoating?

The biggest factor to consider for foam roof recoating is weather conditions. Different times of year require different application methods. And temperatures when recoating is done are incredibly important.

In the desert, with minimal humidity for most of the year, we can have massive temperature swings. If the temperature is too high for the chosen application, then the coating will not dry properly, and the protection can be compromised.

Luckily, this is where our 40+ years of expertise come in. In Phoenix and most parts of Arizona, the ideal times of year to recoat are from March to June, or around October and November.

Two Things to Look Out For Regarding Product Quality

Quality is another incredibly important factor to consider for spray foam roof recoatings. Many of our competitors use cheap products that are made by watering down the base solution.


It turns out the most expensive products you can buy for foam roof recoatings are actually the cheapest, as you get far more for your money.

Yes, you’ll pay more per gallon, but you’ll end up with more protection on your roof between the elements and your foam. You get what you pay for, and then some.

Quality (or lack thereof) is also the main reason we recommend avoiding DIY foam roof recoating solutions from stores like Home Depot and Lowe’s. We’ve found that the products they sell are so watered down and substandard, that, as professionals, we can’t endorse or recommend using any of them.
