How Long Does Spray Foam Roofing Last?

Spray foam roofing is an admirable form of roofing for many reasons. But how long does it last? According to national estimates, twenty to thirty-five years is an appropriate estimate for spray roofing lifetime.

Ultimately, like many roofs, the overall timeline is determined by maintenance, weather, climate, and traffic. The more a roof is exposed to the elements without repairs or maintenance, for instance, will limit the overall lifetime. It is important to note that when the protective coating on a roof is removed, and the roof is cleaned and foam roofing reapplied, the new coating is essentially a new roof. 

How Much Does Spray Foam Roofing Cost?

An average roofing installation price for a spray foam roof can be anywhere within the range of six thousand to seventy-two hundred dollars. The overall price tag will be determined based upon the size, slope, and pitch of the roof. Property owners can expect to pay two dollars and fifty cents to three dollars per square foot. As you may suspect, this translates to two-hundred and fifty to three hundred dollars per square. 

What Is A Spray Foam Roof?

Spray polyurethane foam roofing, also known as spray foam roofing, is truly unique. It’s known as a material that is sprayed as a liquid so that it can expand as a foam. It can create a solid layer across an existing roof. The foam itself is created by coupling two liquids, which are known as a polyol/resin and an isocyanate. It is applied by being sprayed onto the existing roof substrate. Because the foam expertly adheres to many surfaces, it can be installed on any roof slope. This is an admirable quality.

Does Spray Foam Stop Leaks?

One of the really interesting things about spray foam is the fact that using expanding polyurethane foam is actually a great way to stop water leaks. This is because the foam itself will adhere and expand to fill any existing cracks. The application of this foam will also help prevent future leaks. Before using spray foam for any application, make sure to consult an expert and do some research. It also pays to know how to apply spray foam correctly.

Please make sure that you are using proper methodology if you are considering using spray foam for a leak. Water plays an important role in many aspects of a property. If your pipes are clogged, hydro jetting may be the answer. 

Can Spray Foam Rot Your Roof?

The question of whether spray foam will rot your roof is perfectly acceptable. After all, some homes with open-cell spray foam insulation that has been installed on the underside of OSB roof sheathing have exhibited signs of moisture. However, the answer to whether or not spray foam will rot your roof is definitive: no.

Is Spray Foam Roofing Good?

This is an excellent question. To find out more, please review the following bullet points:

  • Straightforward roofing installation – Spray foam roofing is recognized to be fairly easy to work with and manipulate. These roofs are installed by spraying a liquid onto the existing roof and waiting for it to expand into a foam.
  • Energy-efficient  Believe it or not, spray foam roofing has thermal, air and moisture barriers. These barriers have a very high R-value per inch. That means that spray foam roofing has great insulation, which translates into hopefully lower energy bills.
  • Seamless – Spray foam roofing is quite literally seamless. That means that there are fewer opportunities for roof leaks.
  • Flexible – Spray foam roofing has the remarkable capacity of being rather flexible. That means that when the building inevitably shifts, there won’t be significant damage to your roof.

Where To Buy Spray Foam Roofing

How To Apply Spray Foam Roofing

Spray roofing is installed only once the entirely of the roof is cleaned and prepared. The substrate does not need to be stripped, instead, it can be prepared by cleaning it thoroughly with air pressure or a vacuum. All dirt, dust, and contaminants must be removed. Then, the contractor can lay down the polyurethane foam. This foam expands twenty times in size to form a solid and seamless surface. Once that layer has completely formed and dried, it can then be coated in a layer of elastomeric silicone or acrylic coating with granules embedded.
