Overview of Spray Foam 

In short, it is known as “SPF”; it stands for “Spray Polyurethane Foam.”

It is a two-component material made by mixing isocyanate (component A) and polyol (component B) under specific conditions of heat and pressure. 

The liquid mixture of A and B is sprayed onto the surface, where it reacts and forms a solid, lightweight, and fully adhered roofing membrane. 

SPF has been used in various industries since the 1940s. 

However, in the late 1970s, it started being used in the roofing and construction industry for its exceptional insulation properties.

Unfortunately, it is still relatively unknown to most commercial or industrial business owners. 

SPF contains the highest R-value (a measure of thermal resistance), a trait needed to battle the harsh sunny days of Dallas-Fort Worth. 

Customers can expect to pay around $5 to $8 per square foot for SPF, depending on the roof’s size, complexity, and requirements. 

Installation Process

Surface Preparation

First, the existing roof material is cleaned to remove any dirt or debris from the surface to ensure maximum foam adhesion to the material. 

Also, it is essential to ensure the existing roofing material is in the right state. If not, a replacement or installation has to be done before applying SPF.

Spray Polyurethane Foam

Once the cleaning process is complete, the polyurethane foam is applied to the roof surface with a minimum thickness of 1 or 2 inches. 

It can also be sprayed at greater thicknesses to increase its insulation value.

When sprayed onto an existing roof, the liquid foam expands 20 times, creating a seamless surface.

Elastomeric Roof Coating

One of the primary causes of failure in spray foam systems is UV exposure, as SPF is not designed for long-term sun exposure.

For this reason, SPF roof systems require an elastomeric coating to ensure even coverage and prevent UV degradation. 

It is sprayed multiple times to ensure the roofing substrate is covered correctly. 

At the same time, roofing granules are added to the elastomeric coating. It provides extra durability, strength, and resistance to the foam. 

Benefits of SPF

Durability and Longevity

Spray foam systems consist of a robust, lightweight membrane to withstand harsh weather and also improve a building’s structural integrity. 

If installed and maintained correctly, it can last as long as 30 to 40 years on average. 

Also, it must be re-coated every 10-15 years to ensure the system stays intact; spray foam can withstand long UV exposure. 

Ease of Installation and Maintenance

Compared to other commercial materials, SPF can be easily installed without causing any issues or disruption to business operations. 

Most SPF projects don’t require the removal of the existing roofing material; you need to spray the foam. 

In terms of maintenance, it is easy. 

Any minor damage can be easily fixed with a roofing-grade mastic or sealant. 

However, in case of any severe damage, more extensive repair work will be needed. 

Renewable and Eco-Friendly

Since SPF is directly sprayed on the existing substrate, it does not create any waste that usually comes with a roofing project, such as removing the existing membrane.

Also, the materials that produce SPF are environmentally friendly. 

Drawbacks of SPF

Initial Investment

SPF does cost more than other coating options. 

As stated, it costs around $5.00 to $8.00 per square foot, depending on the roof size and required thickness of the SPF to meet the roof’s requirement. 

UV Exposure

As stated earlier, SPF could be better at battling prolonged exposure to the sun. 

Although it is a durable material, it can suffer in quality if installed and maintained correctly. 

To combat this issue, routine service and re-coating every 10-15 years can help to solve this issue. 

In the Dallas-Fort Worth region, we experience blazing sunny days most days, making routine service and re-coating even more compulsory. 

Requires an Experienced Contractor

Unlike other roofing systems, SPF requires a contractor with the experience and knowledge to execute such a project. 

If not, a contractor can damage your roof more than any good. 

Therefore, do your research well before hiring for a project. 

Conclusion: SPF is Suitable for Dallas & Fort Worth

Therefore, with proper installation and maintenance, SPF can work well for roofs.
