    How SPF Compares to Single-Ply Roofing

    Hibu Websites • March 2, 2022

    Your roof is one of the most critical components of your building. As a facilities manager or building owner, picking the right roof to protect your investment in your building and more importantly, your employees is an extraordinarily important decision.

    It doesn’t matter if you are looking to recover an existing roof or undergo a completely new roof installation, you will, no doubt find yourself bombarded with several different roofing options and materials. Two of the most common types of roofing membranes are spray polyurethane foam (SPF) foam roofing and single ply roofing.

    At their core, both of these materials work in a similar fashion. They both cover the roof with a smooth membrane that can help to boost your building’s energy efficiency. Both of these materials are significantly different than the standard roofing shingles that most folks outside of the roofing industry are familiar with.

    Spray foam and single ply certainly have a lot in common. However, don’t be fooled into thinking the two materials are essentially the same or interchangeable. Upon closer inspection, it will become clear that spray foam is the superior choice as a roof covering.


    The Basics of Each Material

    Spray foam is a polyurethane insulator that has been used as a roof covering for over 50 years. The foam compound is made out of two chemicals, typically isocyanate and polyol fiber, that combine as the foam is sprayed on the roof.

    The two chemicals are stored in tanks. Our installation process consists of pumping chemicals from 55-gallon drums stored on a truck. Before the foam is applied to the roof, it is sent from the drums to a proportioner. The proportioner heats the chemicals. In the final steps of the process, The chemical cocktail is sent through a hose to a specialized gun used to spray the foam onto the roof. After it is applied to the roof SPF foam expands to form an extraordinarily dense and rugged membrane.


    Although, there are many types of single ply roofing, each one of these individual materials falls into one of two categories, thermoplastics or thermosets. Thermosets are made from rubber polymers. The most popular of these polymers are neoprene, EPDM, and CSPE. Thermoplasticsmost commonly consist of PVC or TPO. Thermoplastic membranes, as you can probably guess are made from various types of plastics.Both types of single ply roofing are touted for their flexibility and ability to stand up to ultraviolet radiation.



    The Installation Process

    The installation process for single-ply roof membranes is substantially more complicated than the installation process for foam roofing. Single ply roof coverings cannot be applied directly to the deck of the roof. You must first apply insulation over the substructure of the roof. Each sheet of insulation must be properly anchored to the substructure using fasteners and plates.

    Laying down the membrane is the next step in the process. Most single ply membranes come in large roles. Once the single ply is unrolled, fasteners are again used to secure the material to the roof. Where sections of the membrane overlap a heat welder must be used to properly join the seams and secure the single ply roofing.

    Most commercial roofs have pipes, vents or similar items that create obstacles. When applying single-ply roofing, the installer has to cut the material around these obstacles and use specific molded pieces to safely seal the area around the protrusion in the roof.


    Applying SPF foam is a much more straightforward process. As we mentioned above, the foam is applied with a spray gun. The foam is sprayed on the substructure of the roof and slowly expands to fill the desired area.

    A major advantage for foam roofing is in most cases, you do not have to remove the original roof to recover it with spray foam. The foam can simply be applied over the existing roof.


    The Advantages of Self Flashing Roofing

    A major advantage of foam roofing is spray foam is self-flashing. If an installer encounters penetrating items such as pipes or vents, they simply spray the foam around the outside of the object and the foam expands to form an extremely secure seal. The technical term for a roof with no seams or seals is a monolithic roof.

    Monolithic roofs have many functional advantages over their single ply counterparts. They also provide the business owner or facilities manager with increased peace of mind when pitted against single ply roofing membranes. The very nature of monolithic roofs means there are no seams on the surface of the roof. A seamless roof covering means you will have no naturally vulnerable points or areas that are especially susceptible to water or wind damage.

    Maintenance and Durability

    When it comes to maintenance, durability, and longevity foam roofing is far and away superior to any single ply roofing option on the market.

    Foam roofing is relatively maintenance free. An SPF foam roof can easily last for 10 to 15 years with only the most basic of maintenance. Occasionally clearing debris off of the roof is all that is required in terms of regular maintenance. Ultraviolet radiation is the one major nemesis of foam roofing. After about 15 years it is often a good idea to re-apply a fresh topcoat to the roof. This helps to refresh the roof and undo any radiation damage.

    On the contrary, single ply roofs require routine maintenance and delicate treatment.
    If your roof has a relatively soft substrate under the external membrane single-ply roofing is not a good option. In these situations, it is considerably more susceptible to hail damage.

    Also, much like shingles, single ply roofing has to be shipped and handled on its way to the roof. If your building is in a rural area or you find yourself in a situation where the materials are being shipped from a considerable distance the cost of shipping may be a deterrent. Depending on the design of the building, getting the single ply material to the roof could be a precarious proposition.

    SPF foam has the clear advantage in both of these situations. Spray foam is pumped from drums on a truck to a gun handled by the installer. So, chances are that if the installer can get to the roof, so can the foam.

    Spray Foam Offers the Most Longevity.

    Spray foam is the clear winner when it comes to resilience and longevity as well. We’ve already pointed out that spray foam can easily last 10 to 15 years. Technically, SPF roofs can last as long as the building itself. If the roof does sustain catastrophic damage, most problems can be remedied with a new top coat of foam. Most issues that occur with SPF membranes can be fixed more quickly, more quietly, and with fewer expenditures than any other roofing system.

    Single ply roofs cannot be used in conjunction with any other roofing materials or systems. If a single ply roof becomes damaged the repair process can often be difficult, time-consuming, and resource intensive.

    Saving money, increasing your building’s longevity, and using less energy is the trifecta of savings and efficiency for any business owner or facilities manager. SPF roo fing can dramatically increase a facility’s energy efficiency as well as the longevity of almost any roof. Coupling SPF roofing with solar power could lead to major wins for you and your organization. What Each Technology Brings to the Table Deciding to attach solar panels to your roof and install a foam membrane is a big decision, no matter which way you slice it. You should fully understand how each technology is going to impact your building’s energy efficiency. SPF foam is considered a ' cool roofing technology ' . Cool roofing technology is basically any roofing substance that allows a roof to maintain a cooler temperature than it would with a traditional roof covering. In terms of cool roofing, SPF provides several benefits that can add up to big increases in energy efficiency. SPF foam is typically light in color. And, if we think back on some basic science principles, we remember light colors reflect heat while dark colors absorb heat. The more heat your roof absorbs, the more heat will be transferred into the building. Because foam roofing does a great job of reflecting sunlight, building managers are able to maintain the building’s temperature using much less energy. Any HVAC technician worth his salt will tell you air leaks in buildings are a major cause of inefficiency as far as HVAC units are concerned. Air expands to fill whatever it is contained in, so naturally, if there are cracks and crevices in a building, it will find them and escape through them. Most conventional roofs are prime targets for escaping air. Not only do the roofs have seams, but there are also gaps and openings for items like vents and other HVAC equipment. These gaps and openings lead to air loss and a big decrease in energy efficiency. Foam roofing is the perfect antidote for decreases in energy efficiency through escaping air. If properly installed, SPF foam covers all of a roof’s seams, gaps, cracks, and crevices. It will automatically fill around any object that protrudes from or goes through the roof. After SPF foam is applied, you are left with a roof covering that is entirely one piece with no seams or gaps. This provides a tremendous boost in energy efficiency by reducing heating and cooling costs. Many business owners may think about upgrading to solar power and are wary of the cost. The great thing about solar power is you only have one significant expense to account for: the initial installation. After the initial installation there are rarely other costs associated with solar power. You can pay a little more upfront for solar power or continue paying for high-priced utilities month after month. It’s the financial question of whether you want to make a large investment upfront or smaller investments over a period of time. When you opt for solar power, you are not only making a decision about your company. You are making a decision about the future of your community and the future of our planet. The corporate responsibility that comes with making the decision to rely on solar power can be a truly tremendous benefit for many organizations. There is a vast amount of data showing that organizations who embrace social responsibility often see increased revenue, employee morale, brand equity and many more benefits. For example, according to the Network for Business Sustainability , “Improving environmental practices such as reducing pollution and improving waste management can lead to better financial performance through both increased revenues (e.g., enhanced brand equity) and lower costs (e.g., operational efficiencies).” Expected Cost of Solar Power Energy savings from solar power can be a gigantic boost to the financial bottom line of any organization. According to a study by Energy Sage, firms with commercial solar power configurations were able to decrease their overall energy expenditures by about 75%. The average electric bill for a business owner in the study was $1,950. After going with solar power, the electric bill became $500. That is a savings of $1,450 per month. If we extend this trend, we see that the average business owner is able to save $17,400 a year. Over a five-year term the business owner is boosting his bottom line by over $87,000 ! The cost of a solar panel varies depending on the make and model of the equipment as well as the solar panel installer. However, typically businesses are able to pay off their initial investment in three to seven years. The lifespan of a solar panel is 25 to 35 years. Realistically , a business could expect to receive free electricity for 20 to 30 years. Don’t Hesitate to Reach out If you want to start taking steps to increase your company’s bottom line through energy efficiency, drop us a line or give us a shout . We can guide you through the process of installing SPF roofing and answer any questions about the energy savings of SPF and Solar Panels!

    Myth: SPF roofing isn’t water-resistant. Truth: SPF insulation’s initial bonding and expansion process fills and seals any crack or crevice on any roofing substrate, making your new SPF roof highly resistant to water. The closed-cell construct of SPF insulation creates an impenetrable barrier to hold off the effects of moisture.

    HOW HEALTHY IS YOUR ROOF DECKING? When it comes to any commercial roofing repair and replacement, the health of a roofing deck is important to consider. For newer buildings the roof deck is still strong and intact, nothing to worry about outside of extremely rare circumstances and storm damage. That’s not always the case with older commercial roofs. The biggest issue with roof decking is neglect and ignorance from owners. Roof decking can deteriorate and compromise over time, causing big-time risks to your substructure and workspace below. Replacing your roof decking begins with a full inspection of the roof joints, decking, and rafters. Severe weather can create abnormally-sized holes in commercial roofing tiles or metal roofing. It may also puncture deeper into the roof decking. Deeper roof bruising can translate into increased exposure to weather elements and moisture building up under roof decking. This added exposure can bring risks, like mold, water damage, and structural issues if left unchecked. Larger roof damage can add even more risks during roof inspection and repair. At that point Justin Tyler, logistics manager for CentiMark Co . in Charlotte says, “The biggest fear is falling through the roof, not falling off it.”  A certified inspection by a roofing professional, such as our experts at R&A Contracting, will evaluate your roof, including roof decking, to monitor potential water and weather invasion during future storms. If your roof needs to be replaced, check with your R&A Contracting roof inspector to see their notes on your roof decking. We are committed to providing a thorough evaluation of your roof’s health, including the most important part: your roof decking.

    Business owners and facility managers have a lot on their plate. Keeping the business running and the building in tip-top shape can be an around-the-clock job. If y our building has a metal roof and the roof is leaking or seems to be in constant need of repeated repair, these headaches cannot only be tough on your budget, they can also lead to strain on your already precious time. To replace or not to replace, and that is the question. It is a question many folks responsible for the well-being of commercial buildings wrestle with all too frequently. This is a big decision, and a savvy building owner or property manager will take many things into consideration in order to make the right call. To Recover or Not to Recover Is great for building owners or property managers to be on top of the health of their roof. However, just because your roof has signs of damage does not mean the sky is falling and it is time rush out and get a new roof. Instead, the best approach is to take a deep breath and assess the situation with a bit of patience and diligence. Statistics show the typical lifespan for a metal roof ranges somewhere between 30 to 45 years. 30 to 45 years is certainly a reassuring range, but there are a few caveats to this statistic. Proper maintenance is a must to get this type of longevity out of any metal roof. The lifespan of a metal roof will fluctuate depending upon the type of metal from which the roof is made. When it comes to flat metal roofs, leaks are simply an almost inescapable fact of life. Many business owners or facility managers choose to go with a metal roof knowing full well there is a high probability of the roof developing a leak. They typically arrive at this decision because metal roofs are much cheaper to install. They are happy to save money up front, even if it means they will be forking out some bucks down the road to fix leaks. Signs Your Commercial Roof May Have Structural Damage Roofs with irreparable structural damage are typically the only instances where we will recommend a full roof replacement over a repair. A replacement is obviously the most costly option, but sometimes it simply cannot be avoided. Please note: If you suspect your roof has structural damage do not climb on top of the roof. For your safety, please consult a roofing professional if you have any doubt about your roof’s structural integrity. Here are some basic warning signs your roof may be the victim of structural damage. Low or sagging portions of the roof visible from ground level. Large areas of wet or moist insulation. Condensation inside the building. Mold growth inside the building. The roof is missing several fasteners. Need Help to Make the Right Call? Ask R&A Contracting. It can be tempting to fixate on simply repairing a roof to avoid the expense of a full replacement. However, repairing a roof which is ultimately in need of replacement is a penny wise and pound foolish endeavor. Our roofing experts have seen it all. We can help you navigate this tricky situation. We can also help you establish which energy efficient options are best for your business. Don’t hope your roof will make it through one more season. Give us a call today and rest easy with the peace of mind of knowing your roof is up to the challenge of protecting your building.

    How Condensation Forms on Commercial Metal Roofs Let’s take a trip back to our elementary school science class for a refresher on how condensation forms. Just like rain, condensation occurs when there is more moisture in the air than the air is capable of holding. The warmer the air, the more moisture it is able to hold. Condensation becomes water droplets when the moisture in the air makes contact with a cooler surface, such as the underside of your roof. The more humid the air in the building, the more condensation you are likely to have. The warmer the air, the more water vapor it is able to hold. That is why warmer temperatures typically go hand in hand with increased humidity. At first, condensation may seem like a small problem or a nuisance. You may think it’s just a few drops of water and move on with your day. However, those ‘few drops of water’ can cause a tremendous amount of damage to your building and the equipment inside. If enough water droplets make their way into your building, you could have a major moisture problem on your hands. Repeated buildup of moisture can lead to a great deal of damage and expenses. Mold and mildew are typically the moisture problems building owners and facility managers are most familiar with. However, excessive moisture can lead to a slew of other costly and challenging problems. Damage from repeated freezing and thawing can be a major problem if there is too much moisture in your building. This can lead to pipes cracking and damage to other hard surfaces. Many people think that galvanized steel is immune from rust. Galvanized steel may be resistant to rust, but it is certainly not immune. With enough exposure to condensation even galvanized steel will begin to rust. Two Forms of Condensation All forms of condensation are not created equal. In fact, there are two forms of condensation, visible condensation and concealed condensation. Visible condensation is the form you are probably most familiar with. Visible condensation can be easily seen on pipes, windows, and other hard surfaces. Concealed condensation is the second and most problematic form of condensation. Concealed condensation occurs in situations where moisture makes its way inside of the building envelope and forms condensation on hard surfaces. The Effect of Condensation on a Metal Roof Metal and water don’t mix. You don’t have to be a chemist or engineer to understand water on the underside of your metal roof is a recipe for trouble. If water vapors continually gather on the bottom side of your metal roof it could lead to oxidation, which in turn leads to rust. Rust can lead to a catastrophic roof failure. Roof damage from condensation could be difficult to spot. If you have some form of insulation on the bottom of your roof it may be difficult for you to spot oxidation when it is happening. The insulation or covering on the bottom of your roof could conceal visual indicators of structural defects. If you examine your roof from the top, the outermost layer may show no signs of damage. Condensation could be destroying your roof from the inside out, and you may never find out until your roof is in need of repair. The Leading Causes of Condensation in Commercial Buildings Finding the source of your moisture problem can be a tricky proposition. Typically, there are three sources of moisture that can lead to condensation problems, exterior moisture, interior moisture, and built in moisture. Exterior moisture is the moisture source facility managers and building owners seem to be most familiar with. These moisture sources are environmental. Rain, stormwater, snow melt and groundwater makeup this particular condensation category. Issues from these condensation sources are going to vary widely depending on the physical environment around the building. Stopping Condensation Once and for All There are two basic ways building owners can stop condensation from forming on the underside of their metal roof. Keeping air circulating below the roof is the first option. If air is moving continuously, it will not allow condensation to form. This solution seems straightforward. However, it is very difficult and costly to develop and implement a HVAC solution that will keep the air moving and stop the formation of condensation. Insulation Is the Key Insulation is the number one approach for tackling condensation problems in buildings with metal roofs. Installing insulation is the best approach simply because it forms a physical barrier and does not allow moisture in the air to make contact with the cooler surface of the roof. Not all insulation is created equal when it comes to condensation issues. The typical pink, fluffy insulation that many of us are familiar with can act as a barrier, although, it is not an ideal solution. The fatal flaw for this type of insulation is that it is difficult to keep the area below your roof completely covered and sealed with conventional insulation. Gaps and seams in the insulation will allow condensation to make its way through. Additionally, the insulation has to be able to keep the area completely sealed. Achieving complete and total coverage with conventional insulation is a tricky proposition. On the other hand, the very nature of spray foam or SPF insulation makes it the ideal choice for creating a condensation blocking barrier. Spray foam is sprayed into place with a large gun during the installation process. Spray foam expands to fill the installation area. It forms a seamless, rugged membrane. This rugged membrane completely blocks moisture from co-mingling with cooler air. Spray foam is the best solution if you want to stop condensation problems once and for all.

    There’s a lot running through your mind when you realize it’s time to replace your roof. You wonder if your business can afford it right now. “Is there any way we can patch up what we have to get just a little bit more out of it?” The most challenging question you may ask yourself is what type of commercial roof is best for your building. There are so many different roofing options available, just figuring out which type of technology to go with can leave you fighting the urge to pull out your hair. Well, you don’t have to risk any more sleepless nights or trying to figure out your roofing riddle. We are here to help you decide if a new roof is the best option and to tell you why we believe our cool roofing technologies are the best fit for the vast majority of property managers or business owners. The roof is one of the most critical and expensive parts of any building. When choosing to repair, recover, or replace, it is a good idea to make sure you have a complete understanding of just how healthy your roof is. Evaluating a Metal Roof A leaky roof opens the door for many other moisture-related headaches. It should come as no surprise a leaky roof could leave you battling mold and mildew. However, many people fail to realize leaks in a roof can be the cause of incredibly dangerous structural issues. Roof leaks could be the primary cause of anything from ceiling failures to electrical fires. It is not uncommon for roofing panels to be damaged during the repair process. If a roofing panel is damaged there is no quick fix. It must be replaced. Replacing panels can be a costly endeavor. Repairing or making the decision to replace a metal roof takes a great deal of caution, precision, and skill. You want to make sure you entrust the health of your metal roof to a roofer whose work meets the highest standards. Evaluating Flat or Shingled Roofs Deciding whether to repair or replace a shingled or flat roof is both an art and a science.

    Cool Roofing Can Lead to a Bigger Bottom Line A cool roof is an umbrella term for any kind of roofing membrane which uses various technologies to limit the absorption of sunlight. Cool roofs earn their name because they’re designed to deflect the heat of the sun’s rays away from the building instead of being absorbed by the roof and passed into the interior of the building. Cool roofs are not some nifty, roofing gizmo that will be phased out by a new approach in a year or two. They are here to stay. In fact, more than 50% of roofing systems installed on flat or low slope roofs are cool roofing systems. Cool roofs have managed to secure over half of the market because they really do make a big impact In a 2001 rooftop study, surveyors measured rooftop temperatures in Dallas, Texas. Roofs with a traditional surface measured 168 °F while roofs with cool technology measured 126°F. In this study, cool roofs had a 33% lower temperature than their scorching, traditional counterparts. In many cases, the cost of installing a cool roof is very comparable to the cost of installing a roof constructed from typical materials. With nearly identical costs, businesses are able to realize substantial savings right off the bat. Money saved through energy-efficient roofing allows business owners to reinvest in their business.
