DRC’s commercial specialties include:
Spray Foam Insulated Systems
Spray Polyurethane Foam (SPF) roofing systems have been proven to be dependable, long lasting, and very affordable.
Foam roofing is soft and flexible enough to be able to move with the expansion and contraction of the roof with the change in temperature. But it is also tough and resilient enough to withstand foot traffic, heavy downpour impact, high winds and other severe weather conditions. The SPF material can go over a variety of substrates easily. It is manufactured on site and is sprayed to fit your roof perfectly, seamlessly. And because of this, you get added insulation. The R-value of SPF is of 7.14 per 1 inch thickness, which means it provides more thermal resistance with less material than any other type if roofing insulation. Foam roofing produces energy savings when compared to the alternative roofing systems. In a few years, these energy savings alone can pay back for the some cost of the roof.
One very important advantage to SPF though is that it creates a continuous and seamless membrane, with every square inch of it completely adhered to the roof deck. Although flexible, foam roofing material is relatively very dense, composed as it is of billions of tightly packed close cells. It is the only roofing material that has no seams. Because it bonds around roof penetrations such as pipes, vents and edges, these penetrations will remain dry during rain. Also, it can be sprayed in such a way over potential ponding areas in the roof surface to prevent the gathering of heavy standing water as well as to aid the drainage system.
Foam roofs require a minimum of upkeep, creating little waste, and if properly maintained will have an indefinite lifespan. Damaged areas can simply be cut out and re-foamed while settled or depressed areas can just be filled in with more foam. Of course, every now and then and/or after a major storm, it may be advisable to check on your roof. No matter how durable it is, it may need to be cleaned, primed and re-coated, depending on the type and amount of the initial original coating applied.
On the downside, SPF can only be sprayed during specific weather conditions and within a specific range of outdoor temperatures and humidity levels. Going beyond the given installation window may negatively impact the roof’s integrity, showing up as interlaminar blistering in the foam. Even trace amounts of surface moisture on the substrate can result in the foam’s failure to adhere correctly. The optimal climate for applying an SPF roof is warm and dry with no wind. If your region is frequently cool, humid or breezy, it could be months until the weather conditions are acceptable for installing an SPF roof.
Fumes emitted during the spraying process present a potential hazard to employees or customers in or around the building. SPF’s key ingredient, isocyanate, is hazardous when inhaled or when it comes into contact with the skin. Compliance with both the manufacturer’s instructions and the federal Occupational Safety and Health Administration (OSHA) safety regulations is mandatory.
SPF-based roof systems are constructed by mixing and spraying a two-component liquid that forms the base of an adhered roof system. SPF can be installed in various thicknesses to provide slope to drain or meet a specified thermal resistance. A protective surfacing is then applied to the foam to provide protection from the elements. The first component of an SPF-based roof system is rigid, closed cell, spray polyurethane foam insulation. The foam is composed of two components: isocyanate and polyol. Transfer pumps are used to get the components to a proportioning unit that properly meters the two at a one to one ratio and heats and pumps them through dual hoses. The components are mixed at the spray gun, which is used to apply to a substrate. The second component, the protective surfacing, typically is a spray applied elastomeric coating, though hand and power rollers can be used. The protective surfacing also can be a membrane, such as a fleece backed thermoset single ply membrane. The purpose of the surfacing is to provide weatherproofing, protect the foam from UV exposure, provide protection from mechanical damage and assist with the fire-resistant characteristic of the roof system.
The generic types of coatings used on SPF-based roof systems include acrylic, butyl rubber, Hypalon, silicon, aromatic polyurethane elastomer, aliphatic polyurethane elastomer, and modified polyurethane elastomer. Mineral granules or sand may also be added to a coating to provide increased surface durability and aesthetic value.
The National Roofing Contractors Association (NRCA) does not make any recommendations about which SPF products or manufacturer to use although it strongly advise that SPF products meet the roofing standards set by the American Society for Testing and Materials (ASTM), specifically ASTM C1029 [Specification for Spray Applied Rigid Cellular Polyurethane Thermal Insulation], ASTM D6083 [Specification for Liquid Applied Acrylic Coating Used in Roofing], ASTM D6694 [Standard Specification for Liquid Applied Silicone Coating Used in Spray Polyurethane Foam Roofing Systems], ASTM D6947 [Standard Specification for Liquid Applied Moisture Cured Polyurethane Coating Used in Spray Polyurethane Foam Roofing System], and ASTM D7425 [Standard Specification for Spray Polyurethane Foam Used for Roofing Applications].

DRC has partnered with manufacturers who are on the cutting edge of design and product development and who are committed to lasting quality and performance. This ensures a wide selection of tile, foam, and flat roofing products for commercial and industrial projects. You will be buying more than just a roof from us; you will be buying peace of mind, knowing we will be there to service or repair your roof when you need it.
Our commitment to safety carries over to our commercial division as every employee is specifically trained in roofing safety regarding repairs and new construction of all roof types including flat, tile, foam, and shingle. We perform routine reviews on replacement and repair projects, as well as ongoing training and certification for each of our employees. Our manufacturer partners keep us on budget, while frequent safety and product certifications keep our roofs up to code.
Our roofers have thorough training on all roof types for optimum performance and maintenance in Southwestern state climates. We recommend spray foam flat roof systems as the ideal solution for a new or existing commercial building.
Diversified Roofing’s commercial roofing systems are more durable and energy-efficient than ever with spray foam and coating roofing systems in Arizona and Texas. Our specialized spray equipment delivers an even, seamless, sealed finish that is perfect for flat or low-sloping roofs. Our roofing experts deliver high-performing results for lasting roof construction on our commercial projects.
Many commercial buildings have flat and uneven roofs. This creates a problem when it comes to water runoff, in areas where heavy rains are frequent and continuous. For flat commercial roofs, though foam spray is incredibly durable, and surprisingly lightweight. Flat roofs have a lower weight load than pitched, making foam spray systems ideal and low maintenance. In low-slope and uneven roof situations, the lightweight foam continues to perform. When Texas or Arizona roofs have uneven spots, our roofing specialists can spray on the roofing in an extra layer to bulk it up, even it out, make a slope, and meet other specs.
Foam roofing involves mixing of two liquids that Diversified Roofing experts spray foam onto a base surface. This expands and dries forming a rigid, strong, lightweight surface. A protective coating is applied on top, sometimes with sand and other aesthetic components. The combination results in a superior low maintenance roof solution for nearly every commercial situation.
Foam spray roofs go on soft and quickly harden into a dense, flat commercial roof that not only withstands heavy winds and rain, but also severe humidity and heat. If spray foam roofs on flat or sloped rooftops are dented or slightly damaged, they generally don’t leak immediately, which gives you time to call your Diversified Roofing specialists for a quick maintenance visit at your convenience.
When properly cared for, commercial spray foam roof systems can last over 50 years. Other roofing companies will replace their flat commercial roofs, but commercial grade Diversified roofs will stand the test of time. Maintenance on foam spray roofing is much easier than traditional flat commercial roof systems and will allow you to focus on your business, rather than worrying about the roof over your head.
You will also notice significant savings on utilities with a new commercial spray foam roof or spray coating system. In Texas, Arizona, and other hot climates, foam roofs pay for themselves with outstanding insulation qualities and maintenance. During the drying process, the materials expand and bind to the base layer for a tight, finished roof. If you are looking to trim down your air conditioning or heating costs, a foam roof is a great option.
