How Long Does Spray Foam Roofing Last?

“Spray foam roofing is one of the best roof coatings, and it is perfect for all types of roofs, both residential and commercial.” This is an universally used sentence by all roofers, and it is the truth.

But today, we will not discuss how good spray foam roofing is. Instead, we will discuss how long it lasts once applied to the roof, which will give you more clarity before investing in spray foam roofing redding. So let’s find out in detail.

How long does Spray Foam Roofing Last?

Different types of roofs can last different amounts of time depending on what they are made of and where they are located (climate and atmosphere). The weather plays a big part in this. For example, spray foam roofs usually last between 15 to 20 years on average. But some spray foam roofs have lasted more than 55 years! That is about half a century amazing, right? 

Now let’s talk about the best part – Unlike other flat roof materials, you can keep renewing spray foam roofs, which is a big plus. Yes, you heard that right. 

But what does that mean for you?

So, here’s the deal: if you take good care of spray polyurethane foam roofs, they can last a really long time. This includes regular inspections, cleaning, and prompt repairs. But hey, some people might not believe that, right? Anyway, to be honest, if you look after any roof really well, it’s going to stick around for ages. But eventually, even the best roofs wear out and need replacing, no matter how much love you give them.

Secret to Making Your Spray Foam Roofing Last Forever

So, how can you make sure your spray foam roof lasts a long time? Well, the key is to shield it from UV light. UV light is like the top enemy of polyurethane foam, which is what spray foam roofs are made of. If you want your roof to do its job of keeping your place insulated and waterproof, you’ve got to keep it safe from the sun. If the sun damages the foam, it can soak up water and get ruined.


Some people may think that the coating on top of a spray foam roof keeps it waterproof. But actually, the main job of that coating is to shield the foam from the sun. To really protect your roof, you need the coating to be at least 15 dry mils thick. The thicker the coating, the longer it will hold up against the sun’s harmful UV rays.

Foam roofs usually require upkeep every 10 to 20 years. If you shield your roof from the sun, it can last indefinitely. You’ll know it’s time for maintenance if you spot any visible damage or when the top layer gets to be about 10 mils thick. If there’s damage, you will just need to apply a new coating to the top layer.

It is pretty straightforward: keep your foam roof safe from the sun and stay in great shape forever.

Roof Maintenance

Building owners, property managers, and real estate executives need to make sure their spray foam roofs are well looked after to make them last longer. It is important to check SPF roofing systems every so often, especially after bad weather like rain, hail, or strong winds, which can cause damage. 


If you spot any small cracks or damage, they can be fixed easily. For bigger problems, the damaged part can be removed and replaced with a new layer of spray foam and coating by spray foam experts. It’s also a good idea to add a new coat regularly to extend the life of your foam roof. With proper care and maintenance, a foam roof can last indefinitely.
