What is Spray Foam as Roofing Material?
Spray Foam roofing or Spray Polyurethane Foam (SPF) roofing is a technique of building construction (walls or roofs) by using Spray Polyurethane Foam.
SPF is a type of plastic that goes from liquid to solid in a matter of seconds that increases in volume by approximately 30 times as it dries. It is one of the most cost-effective and sustainable roofing, insulation and waterproofing system available today.
SPF-based roof systems are constructed by mixing and spraying a two-component liquid that forms the base of an adhered roof system.
The SPF can be installed in various thicknesses, as per the customer’s needs, to provide slope to drain or meet a specified thermal resistance (scientifically called R-value). A protective surfacing is then applied to the foam to provide protection from the elements.
The first component of the SPF-based roof system is the rigid, closed cell, spray polyurethane foam insulation. This foam comprises of two components, namely, isocyanate and polyol. The components are mixed at the spray gun, which is used to apply them to a substrate.
The second component which is the protective surfacing typically is a spray applied elastomeric coating (though hand and power rollers can be used as alternatives).
The purpose of this surfacing is to provide weather-proofing, protect the foam from UV exposure, provide protection from mechanical damage and assist with the fire-resistant characteristic of the roof system.
Now that you’re aware of what the Spray Foam roofing is, both generally and technically, you must read on to find out the various pros and cons of the roofing system that will help you in deciding your roofing system!

It has great insulation and acts as a barrier for heat, air, and moisture. It keeps heat out in the summers and is warmer during winter that helps in lowering the energy costs for the facility owners.
You can change the look of the physical appearance of the roof as per your needs. The texture could be soft or semi-rigid or even high-density.
