Cost for installing spray foam roofing

It will cost about 4 – 7 dollars for industrial roofing of 20,000 sq. foot – depending on the labor and materials for installation.

The variables that influence the roofing cost include:

  • The SPF thickness
  • The roof dimension
  • Silicone covering
  • The state of the current roof
  • Rooftop access  
  • Maintenance
  • Warranty

How is it installed?

The substrate or current roof has to be prepared before the spray foam installation can begin. As opposed to stripping the current rooftop, the expert will probably make the substrate ready by removing all contaminants, soil, and dust. This is can be achieved by sweeping or using pressure vacuuming.

Then the contractor will proceed to fix the 1st layer of polyurethane foam, which is created with a mixture of 2 fluids (an isocyanate and a gum/polyol) as it is sprayed onto the current rooftop substrate.

Then the fluid creates a foam that grows to 20 x its size to become a strong & consistent foam surface. After the foam has extended, this layer gets thick 1 – 1.5 inches. It can be used on any roof slopes since the polyurethane foam sticks to almost any surface.

A layer(s) of acrylic covering with installed granules or elastomeric silicone is used to coat the finished SPF layer. This covering is large somewhere in the range of 0.02 – 0.03 inch. The covering shields the SPF and rooftop from climate, UV light, typical wear and gives the necessary fire evaluations. The finished installation will make the rooftop be tough, seamless, and damp-resistant.


The advantages of using SPF roofing as opposed to other types, as far as performance, durability, installation, and the cost is concerned.

  • Simple to install

The simplicity of installing SPF roof can save you money and time. The foam and coating application is quick and can be done with generally no interference with the everyday schedule of the business.

Since the method involves spraying foam onto the substrate, this implies that the foam can fit in with any type of roof, even the irregular ones. After the current rooftop has been cleaned, the SPF rooftop can be used directly on shingles, asphalts, solid, wood, and metal.

  • Saves energy

SPF roofing acts as a barrier against heat, moisture, and air to give the greatest R-value per an inch that implies the material gives better protection to the building.

The foam inhibits the flow of heat in during summer and in winter, it brings down the cost of energy. The silicone top covering opposes UV light, securing the foam and lessens adsorption of heat.

  • Simple to maintain

When an SPF rooftop is introduced, it requires negligible upkeep. With proper maintenance, your SPF rooftop can last more than 50 years. But you should inspect the system twice a year, in Fall and Spring. Extra checkups are recommended following an event/natural disaster that can damage it.

If a silicone re-coating is required, there’s no need to detach the current materials; you simply apply the new coat over the present system.

    • Moisture resistant and seamless

The main cause of roof leakage is penetrations and seams, SPF eliminates this weakness. Since it can fill seams, cracks, and holes,   in the current substrate.

The use of the polyurethane foam enables the contractual worker to level out the rooftop to diminish the opportunity of ponding water. The foam material can extend and contract based on temperatures outside, lessening the probability of splits and breaks.

  • Sustainable and Renewable Roofing

SPF rooftops make practically zero waste amid its lifetime. Most times, there is less to no substrate stripping, and the SPF is introduced to the top – it eliminates waste and the requirement for expensive roof removal. The materials that are utilized for SPF roofing are likewise Eco-friendly.
