What is a foam roof, you ask? Foam or SPF (Sprayed Polyurethane Foam) is one of the most common types of roofing alternatives used on commercial buildings and some residential properties, particularly those with low slopes or flat roofs. The foam consists of a combination of polyol and isocyanate. Both of these elements are fed into a spray gun, heated up and then pumped onto the surface of the roof. During its application, small air bubbles are trapped inside the foam, making it more effective for insulating the roof against both heat and cold. In fact, according to some studies, the use of foam roofing has been shown to result in energy savings of about 30% or more when compared to other kind of roofing systems. This article will go further into detail about why foam roofs have been becoming increasingly popular over the years.

Advantages of Foam Roofing


Aside from its protective coating, foam roofing is also known to be highly resistant to things such as storm damage and other weather issues. It also requires little maintenance and repair, which means it doesn’t wear easily.What is a Foam Roof? - Saving Energy By Up to 30%


Foam is roughly one-eighth the weight of other conventional roofing materials. This means that it usually has more flexibility when it comes to architectural design. This feature also makes it ideal for cost savings since it helps to eliminate the need for elements such as structural reinforcement.

Seamless and Flexible

Due the fact that foam roofing is applied in its liquid foam, which expands later on, it is able to create a continuous, protective, seamless, and flexible barrier around the pipes, vents, and any other kinds of protrusions that may exist throughout the roof. This particular feature makes it ideal for commercial buildings where there are usually a high number of perforations. Another good thing with foam roofing is that it’s self-flashing, which means fewer expenses in terms of flashing materials.

Green Option

Foam roofing is an environmentally friendly option since it requires minimal upkeep that translates into less waste and repair obligations. With the right coating, it can also reflect heat; thereby helping to reduce its loss in urban areas. This particular effect is referred to as the heat island.

Cost Effectiveness

The truth of the matter is that foam roofing is currently one of the least expensive options when it comes to commercial roofing application. In addition, it is also one of the easiest materials to apply, which usually means fewer labor costs.

Repair and Maintenance

Even though it may not be much, foam roofing still requires intermittent maintenance checks and repairs. However, this is usually based on individual situations. In fact, depending on the kind of foam roofing material one uses and the roof surroundings, one may not require a roof inspection for as long as 5 years. In such a situation, you will only need to re-apply the protective coating every now and then in case it starts to wear.

In the event that the roof foam is damaged due to storm debris or other elements, it is usually recommended that you repair it immediately to avoid any issues that may affect its structural integrity.


So, what is a foam roof? This roofing material consists of a foam or SPF (Sprayed Polyurethane Foam), and is one of the most common types of roofing alternatives used on commercial buildings and some residential properties. Particularly those opposite a pitched roof with low slopes or flat roofs. From the information provided above, you can clearly see why commercial property owners and contractors prefer to use roof foaming. Aside from its numerous benefits, it is also an environmentally friendly alternative.
