If you frequent our blog, you know that West Roofing Systems is the expert in Spray Foam Roof installation. But did you know that there are more benefits to spray foam outside the cost and energy savings?

Here at West Roofing Systems, we’ve installed over 57,700,000 sq. feet of roofing domestically and internationally and during that time we helped business owners protect their facilities with spray foam.

Spray foam roofing can be used to solve your commercial building’s toughest challenges, inside and out. In this article, we cover three unique, but common uses for spray foam.


What is Spray Polyurethane Foam Roofing?

SPF Installation

SPF Installation

Spray Polyurethane Foam, more commonly referred to as SPF, is a liquid that is sprayed and expands into a foam, creating a solid layer across an existing roof. While SPF roofing is not the most known type of roofing material, the technology has been around since the early 1960s for industrial, commercial, and residential facilities.

For an average 20,000 sq. foot commercial roof, it will usually cost between $4.00 and $7.00 per square foot in materials and labor to install a typical SPF roofing system. This price range is for an SPF roof of average thickness and building structure. *



Commercial Ductwork Insulation

The ductwork is one of the most important systems in your commercial building. According to Energy Star, 20 to 30 percent of the air that moves through a duct system is lost due to leaks, holes, and poorly connected ducts.

Improperly sealed ducts could contribute to energy loss for your facility and ultimately a monetary loss for your bottom line. A properly insulated ductwork system can protect your facility from variable temperatures, water damage, and mold.

With spray foam being utilized on new and existing ductwork, the foam can completely adhere to the duct surface and improve the efficiency of the HVAC equipment.

The benefits of using spray foam on your ductwork include:

  • Increase insulation of the ducts
  • Reducing air leaks
  • Allowing temperature to be maintained inside the duct
  • Temperature maintenance outside of the duct


The spray foam system will conform to any variety of shapes and transitions without the need for costly flashing materials. This also prevents the need for fasteners and eliminates seams. You can tailor your spray foam system in place and eliminate ‘cut offs’ and scrap material from your project.



Roof System Tie-Ins

Not all roofs are created equal. If you have multiple levels of roof systems or you have multiple types of roof systems, this can be a problem for potential leaks.

Spray foam can be utilized in an area where two different roof types meet. This area tends to collect substantial amounts of draining water as well as snow drifting. By installing the spray applied product, you create a seamless protective layer prevents any water from backing up under the roof or flashings.



Non-Conventional Building Shapes

We have seen some unique buildings in our days, not every building is straightforward. The remarkable thing about spray foam is that your contractor creates a roof system as they apply the liquid onto your building. This means that they can cover non-conventional, even awkward shapes.

Traditional commercial roofing comes in prefabricated shapes – whether it’s a roll of membrane or a sheet of metal. This means that the contractor has to work around your building shape, costing you time and money. The number of roof seams also increases when you introduce more pieces of roofing material.

A spray foam system will conform to a variety of shapes and transitions without the need of costly flashing materials. While membrane or metal roofing come in prefabricated shapes, you can apply spray foam right onto your existing system, which means that you have endless opportunities with the shape of your roof system.


From installation and throughout your warranty, the savings of your new SPF can pay off the roof system and save you money down the road. This is why many commercial and industrial facilities choose SPF as their preferred roof system.

An SPF roof pays for itself quickly with energy savings and longevity of the roof. You can work with your contractor to calculate potential energy savings to make sure are proactive about your facility cost-savings.
