Why You Need to Add Roofing Insulation to Your Service Offerings


Spray foam roofing is one of the most popular and versatile forms of roof insulation. It has been tested over many years and proven by experts to be dependable, durable and help provide a barrier to heat flow in your client’s home. Spray roof insulation will even help to keep their home warm in the winter and cool in the summer. Keep reading for a full list of the benefits associated with insulating roofs with polyurea and polyurethane foam.


Reasons to Insulate Your Roof




Spray Roof Insulation and Polyurea


What is Polyurea? Polyurea is defined as a type of elastomer or organic plastic. It provides a base for different protective coatings used in applications such as roof insulation and automobile parts. Polyurea is a modern roof sealer widely used in roof coating and lining.  

Spray foam is essentially a chemical product that is created when two materials are mixed with each other. In many cases, roof insulation experts use polyurea or polyurethane. The resulting foam forms a continuous insulation and an air sealing barrier on roofs and walls. It provides waterproofing to roofs and ceilings, helping keep homes dry even when it rains and during storms.


The two materials are often mixed and sprayed on site, where the insulation is needed. When the liquids are mixed, they react and expand very fast on contact with the target surface. The reaction results in foam, which insulates, forms moisture and vapor barriers and seals all gaps. The result of the spray roof insulation process is a high-quality insulation barrier that actually resists heat transfer. It keeps the home safe and dry and it also helps maintain heat in winter and cool atmosphere in the summer.


Types of Polyurethane Spray Foams


There are three basic types of SPF or spray polyurethane foam. These are the high density, medium and low-density models. The high-density type of SPF is often used for spray foam roofing and exterior applications. Medium density, on the other hand, is used on unvented attics, for filling interior cavities and for continuous insulation. The low-density spray foam is used for unvented attic applications and inner cavity filling.


Other issues also need to be considered during polyurea coating. One of the most important of these is roof coating. Spray roof insulation should be accompanied by roof coatings so as to prevent any damage to the foam by harmful UV rays and the elements. According to experts, it is crucial to protect spray foam insulation from the elements. Otherwise, it may expand and contract, resulting in damage. Once the spray roof insulation is applied, it should be sprayed with an elastomeric roof coating to create the protective layer. This protective layer is a durable, weather-resistant surface that provides superior protection to the roof. It can be walked on during regular maintenance of other components found on the roof. Elastomeric roof coating is necessary for spray foam roofing. It ensures the insulation itself is protected from the elements and will keep the roof insulated for many years to come.


Elastomeric material that protects roof insulation includes products such as polyurea, crushed rock, urethanes, silicone, and acrylic. Even crushed rock can provide protection to the spray foam insulation. The roof coating is installed as a base coat which is then followed by a top coat. Urethanes are preferred across the US, especially in Midwest and Southern States, as they are among the strongest coatings in the market. You do not need to keep paying high energy bills or risk leaks after heavy rains or due to the sun. The roof insulation will be completely protected from corrosion, wear and tear and the elements.


Properties of spray foam coating: the single most important form of protection provided by SPF or spray polyurethane foam is thermal protection. Thermal resistance comes in various forms and is one of the main reasons homeowners, construction companies, and especially roofers recommend polyurethane foam to seal the roof and protect the home. Polyurea coating protects against conductive heat transfer where heat travels through a medium such as metal. Metal roof coating also protects against radiant heat transfer. This is where heat is transmitted in the form of light energy. It also protects against convective heat transfer where heat is transferred through a fluid such as air or water. Regardless of the type of home or roof you have, it should be professionally sealed using roof sealer waterproofing systems.


Types of Roofs that Work Best with Spray Foam Insulation and Polyurea


Spray roof insulation works well with all kinds of roofs. In the modern building and construction industry, there is a desire to build durable, long-lasting roofing systems that are low maintenance with high energy performance. This makes SPF the soundest insulating material in the market today. It is frequently used by homeowners to protect their roofs, insulate the home and seal it completely. It can easily be applied onto any substrate such as wood, concrete, steel, metal and other materials used in roofing.


SPF is widely used to insulate all sorts of homes and buildings. It includes those with a flat roof and those with a slanted roof. It is easier to install a tapered foam roofing system and also less costly compared to other tapered roofing systems. In addition to all its great roofing properties, SPF – spray foam insulation can strengthen the walls and roofs of a home and protect it from mold and airborne particulates. When sprayed on vertical terminations, mechanical unit risers, and protrusions, they become an integral part of the roofing system and minimize the need for additional materials.


Polyurea from SprayEZ


SprayEZ is among the largest manufacturers and suppliers of spray roof insulation products, which include polyurea and dispensing equipment. The polyurea that SprayEZ manufactures is designed for use with the Spray Urethane Foam kits to insulate buildings. Buildings can be protected as either Closed Cell Urethane Foam, as a full wind barrier and insulated envelope or Open Cell Foam as a wind barrier. This is suitable in areas where there are no contractors and where large equipment cannot access a site.


In other regions with large applications, high-pressure equipment can be used. It can spray all types of foam such as 3-pound roofing foam, 2 pounds closed cell interior spray foam and the half pound open cell foam. The equipment available through SprayEZ allows users to make adjustments for higher pressure and heat levels necessary. You can now buy polyurea, spray urethane form kits and the material directly from the website. Check out the relevant web pages for detailed information, including video, on how to use the equipment and much more.




Our line of polyurea is called ExpandoThane. ExpandoThane comes in different packaging, making it easy for customers to choose.
