Spray Foam Insulated Systems

General Information

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.

Materials/Tools Needed

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.

Quality Standards

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].

Metal Roofing Systems

General Information

Metal roofs, in addition to the traditional corrugated panels and standing-seam applications, now come in shingle, shake, slate and tile designs as well as in textures and finishes that make them look like wood, stone, or clay, allowing them to go well with homes of just about any architectural style. No wonder they are back in fashion among new home owners and house builders.

But generally, commercially available metal roofing comes in two basic forms: sheet panels and shingles. Sheet metal panels, available in a variety of sizes, thickness and technical specs, are further classified according to the method they will be joined together to form a system: panels for a standing-seam system and panels for a batten system. Metal shingles on the other hand are stamped sheet metal with decorative finishes and textures which are available as simulated clay or stone tiles, wood shakes or slates as well as in such other decorative shapes. These metal shingles are given multiple-layer factory finishes that make them indistinguishable from the real thing.

For residential purposes, there are two general types of metal roofing systems used: concealed fastener and exposed fastener systems. Exposed fastener system cost less than the concealed fastener system. Which one to use depends on the architectural look you want to achieve. With metal roofs, you can also have such external structures as ridge vents, snow guards or brackets, gutters and downspouts, water diverters, turbine vents, skylights and solar tubes custom-built and installed by your roofing specialist on-site to go with the needs and the desired style you want to give to your home.


Metal roofs have proven durability, capable of lasting for decades. They are heat-reflective as well as weather- and fire-resistant. They are energy efficient and green. They can also come in a variety of finishes and in just about any style and color to suit your taste and budget. Metal roofs, though relatively more expensive than traditional roofs and need professional installation, are increasingly becoming a popular roofing material of choice because of their longevity, because they are easier to maintain and upkeep, because they are lightweight and because they are recyclable and thus “greener.” During electrical storms, a metal roof is also safer because if struck by lightning, it is not flammable or combustible. The metal would disperse the electricity safely throughout the building’s structure.


Installing metal roofing can be an intricate process that should best done by a paid professional roofing contractor. Also, the initial cost of a premium metal roof is higher than most other roofing materials. During a torrential downpour or hailstorm, metal roofing is bound to be noisier than any other types of roofing systems. Metal is also susceptible to denting and bending when hit, especially if repeatedly, by heavy hailstorm and high winds.

Materials/Tools Needed

Nowadays, most metal roofing systems are made from steel and aluminum, although those made with other materials like copper and alloy may also be available at a higher price. Aluminum is relatively a softer and lighter metal than steel and is more prone to denting and damage. However, it won’t corrode, unlike steel once the protective finish gets compromised by age, wear and tear, and/or long exposure to the elements. But aluminum is also more expensive than steel.

Steel is by far the most common of available roofing materials. It is heavier, sturdier, and cheaper than aluminum. It can be galvanized. Steel is usually zinc-coated for corrosion protection and then sealed. In sealing, it is first coated with epoxy primer, followed by another coat of baked-on acrylic. Most manufactured steel roofing systems also now come additionally coated with Kynar, a fluorocarbon, for extra strong protection. Stainless steel roofing is more expensive than regular steel but it is rust-proof and won’t corrode. If coated with terne, an alloy made of tin and lead, stainless steel will have a natural matte-gray finished look.

Quality Standards

Certification of metal roofing products is available through the Metal Construction Association’s Metal Roofing Certification Program based on industry standards published in the Guide Specification for Residential Metal Roofing. The roofing standards published by the American Society for Testing and Materials (ASTM) also include sections pertinent to metal roofing products, specifically ASTM E1514 [Standard Specification for Structural Standing Seam Steel Roof Panel Systems] and ASTM E1637 [Standard Specification for Structural Standing Seam Aluminum Roof Panel Systems.
