How the TDP-1 Standard provides a consistent method for evaluating the adhesion strength of roofing materials. 

Understanding material testing standards and their results can be a bit confusing at first. In a recent article, the Single Ply Roofing Industry (SPRI), provides a simple breakdown of the TDP-1 Standard and how it impacts product testing. The TDP-1 Standard, officially titled, “Test Standard for Comparative Adhesion Strengths of Waterproofing Membranes, Membrane Adhesives and Board Stock Materials Used with Low Slope Roofing Systems,” was developed to provide a reliable and repeatable method for measuring those bond strengths through a specialized tear drop peel test. 

The TDP-1 Standard focuses on determining the maximum failure load; the highest force reached before an adhesive bond fails. Drawing on “Peel or Stripping Strength of Adhesive Bonds” (ASTM D903), the standard is designed to help qualify individual roofing components and assess material compatibility while reducing the need for larger and more costly roof assembly testing. 

The testing process follows a structured methodology intended to deliver objective results. Waterproofing membranes are prepared in consistent strip sizes, while board stock materials such as insulation board, cover board, plywood and oriented strand board (OSB) are cut to fit the test apparatus. Materials are conditioned in a controlled laboratory environment before assembly. 

Once assembled according to manufacturers’ guidelines, specimens are tested using a calibrated tensile machine that applies a perpendicular load at a constant rate. During testing, technicians record the maximum failure load as well as the mode of failure, which may include adhesive failure, cohesive failure or delamination. 

A key feature of the TDP-1 Standard is its emphasis on thorough reporting. Test reports document specimen details, preparation conditions, equipment calibration information, failure loads, failure modes and any deviations from the procedure. Statistical analysis and supporting images may also be included when required. 

The standard has become a valuable tool for comparative testing, component qualification and product development. By allowing manufacturers and testing laboratories to evaluate material combinations on a smaller scale, TDP-1 helps identify promising systems before committing to extensive assembly testing. The result is a more efficient, transparent and consistent approach to assessing roofing material performance.

Joel Stanley shares how Anchor Products is helping manufacturers support mental health awareness across the roofing industry. 

Mental health can be difficult to talk about in construction, but for Joel Stanley, the need to speak up became impossible to ignore. Joel, the founder of Anchor Products, joined McKay Daniels, CEO of the National Roofing Contractors Association (NRCA) and Lynsey Hull, CEO of Tyelus, for this episode of Roofing Road Trips® in a conversation about mental health, suicide prevention and the growing collaboration between NRCA and the Single Ply Roofing Industry (SPRI). Joel’s perspective offered a clear look at how one manufacturer’s concern for workers helped spark broader action. 

Anchor Products, a rooftop equipment attachment manufacturer, works closely with roofing manufacturers, contractors and industry partners, giving the company a direct view of how collaboration can support a safer, healthier industry. “We work with all the different roofing manufacturers on a daily basis,” Joel said. “And it's been fun to be involved with so many great contractors and great roofing manufacturers throughout our industry and really share our insights and learn from what other people are doing as well.” 

That collaborative mindset carried into Joel’s work with SPRI. He said Anchor Products has been heavily involved with the organization for years, with Anchor team members chairing several SPRI task forces. When mental health and suicide prevention came up as an urgent industry need, Joel saw a place where manufacturers could help extend the reach of existing efforts. 

After hearing NRCA CEO McKay Daniels speak about the impact of suicide in the roofing industry, Joel said the message stayed with him. It was not only the scale of the issue that moved him, but also his own family experience with suicidal ideation and mental health challenges. “How great would it be if we had an industry that cared about my kid,” Joel said, reflecting on what it would mean for every parent to know their child worked in an industry willing to care about them as a whole person. 

At a subsequent SPRI meeting, Joel stood and asked the organization to act. Joel reflected, “I stood up and I said I would like to start a task force that can address mental health and that we can look at what our industry can do, what the roofing manufacturers can do to help.” His goal was not to create a competing message or a separate campaign. Instead, Joel described a desire to work with NRCA, use existing resources, and find ways for manufacturers to help carry a unified message into the field. 

For Joel, that responsibility is shared across manufacturing, distribution, contracting, service and leadership. “We can't rely on somebody else to save my friend,” Joel said. “I actually have to do something myself.” That sense of care remains at the center of the effort. As Joel put it, “Everybody deserves to be cared for.”

Understanding the essential components of a roof and their role in overall performance. 

A roof is far more than just the outermost layer of what can be seen with the naked eye; it is a complex system carefully engineered to provide protection, ensure energy efficiency and, in some cases, support additional structures like solar arrays or green roofs. For roofing professionals, understanding the components of a roof assembly is essential to designing, installing and maintaining a system that performs effectively over time. In a recent article, “Back to the Basics (Part 2): What is a Roof Assembly?,” the Single Ply Roofing Industry (SPRI) dove into this topic.  

Defining a roof assembly 

The article opened by establishing the basics – what exactly is a roof assembly? It referenced the 2024 International Building Code (IBC), which defined a roof assembly as a system designed to offer weather protection and resistance to design loads. It went into further detail to note that a roof assembly includes a roof covering and roof deck or a single component serving as both the roof covering and the roof deck, with the option of also having underlayment, insulation and vapor retarders. Each of these layers plays its own role: 

• The deck: All of these different layers, both required and optional, are built upon the roof deck. In this way, the roof deck is the foundation of a roof. These decks are often made from materials such as steel, concrete or plywood, with the choice depending on the building type and the specific load requirements. 
• Insulation: The insulation layer is another critical component, responsible for regulating thermal performance and reducing heat transfer. Proper insulation helps maintain a consistent indoor temperature and lowers energy costs, making it a vital part of energy-efficient roof systems.  
• Waterproofing: Installed on top of the insulation, a weatherproofing layer, usually composed of waterproof membranes, safeguards the building from moisture infiltration, protecting the interior from water damage. This outer layer, which can include materials such as modified bitumen, PVC, EPDM or TPO, also enhances durability and shields the roof from external elements like wind, UV radiation and harsh weather conditions. 

Modern advancements in assemblies 

The article then went into the recent evolutions of roof assemblies as technologies and materials designed to meet modern performance standards and environmental regulations have been developed. For example, vapor and air barriers are now frequently added to manage moisture migration and improve the overall functionality of the building envelope. These innovations not only prevent condensation, which can lead to material degradation, but also contribute to the long-term durability of the roof system.  

Additionally, green roofing systems — complete with vegetation layers — have gained popularity, offering natural insulation and aiding in stormwater management. Photovoltaic (solar) systems are also increasingly integrated into roof designs, allowing buildings to harness renewable energy and reduce their environmental impact.

Roofing professionals share insight into the importance of mental health awareness and care in the industry.  

If you didn’t know, May was mental health awareness month in the United States! Mental health is a key issue in our industry, with construction having the second-highest suicide rate of all major industries in the U.S. To talk about how the industry is working on addressing this issue, Lynsey Hull of Tyelus, McKay Daniels of National Roofing Contractors Association (NRCA) and Joel Stanley of Anchor Products came by for an episode of Roofing Road Trips®. 

The mental health movement in the roofing industry has been steadily growing over the years as people get more informed about the severity of the issue. A huge moment in that timeline came in 2024 when NRCA launched a microsite about connecting professionals to resources. McKay spoke about the page, sharing, “Knowing a place to start is half the battle, so we made BeToughEnough.org with the goal of providing some basic level resources, a place for both employers and employees to learn how to talk about mental health. And it has the NRCA logo on it, but it’s not about NRCA, it’s bigger than just one organization.” 

And in the years since that page launched, the movement has truly grown far beyond just the actions of one organization. For example, in 2026 the Single Ply Roofing Industry (SPRI) association announced a mental health task force, partially inspired by NRCA’s work. Joel shared the story:  

A couple of years ago, McKay  was speaking and he talked about how our industry focuses so much on physical safety. Which makes sense, we suffer from about 400 or so fall deaths a year... But he also pointed out that we’re forgetting the mental side of things. And those numbers are so much bigger; I think he said we suffer from over 6,000 deaths a year from suicide. And it really hit me, I have a family member who has struggled with mental health and it got me thinking.  

What was Joel thinking about? He realized that organizations like NRCA are great for general awareness, but they don’t have the personnel to be on jobsites all over the country, seeing people day-in and day-out and being able to notice when someone is struggling. Who has that presence? Roofing manufacturers. He explained, “Manufacturers have people on job sites every day that are inspecting and advising. Those people see contractors periodically throughout the year and I realized when you see people frequently, but not every day, it allows you to see and recognize changes in them. If we can equip those people with skills and resources, it could a do a lot of good.” 

Armed with this realization, Joel reached out to both McKay at the NRCA and the SPRI board to see if they could build a collaboration that could take his idea and put it into action. The result was the creation of the SPRI mental health task force.  

Lynsey was there when Joel presented his idea and immediately jumped on board to help co-chair the task force with Joel. He recalled:  

The response was really overwhelming. Our first meeting as a task force was standing room only. I've had people reach out who don't even attend SPRI and say, ‘Hey, our representative told me about this. I really want to be involved. I have some background in this or I'd like to contribute or we had this idea. What do you guys think about that?’”  

The first thing the task force worked on was collaborating with NRCA to raise awareness of the resources available on BeToughEnough.org. Lynsey explained why this was their first move, sharing, “What we're really trying to avoid is having multiple messages out there and splitting the focus. So we started by just finding ways to raise awareness and point people to NRCA’s existing resource library.”  

From there they started to collect and share stories of how people can speak up or reach out and make a difference on their job sites. Stories like the one Lynsey shared:  

Speaking up or reaching out doesn’t have to be big. I wear t-shirts from a brand that has different messages on the back. And I remember one day I was just walking my dog and a guy came up to me and grabbed my shoulder and just said, ‘I needed that today, I just wanted to say thank you,’ in reference to my shirt. And he left. When I got home I looked at the shirt and it read ‘I'd rather hear about your battles than learn you lost the war.’ And that just struck me, how just something so simple for me, wearing that shirt, meant so much. 

And at the end of the day, it’s interactions like the one in Lysney’s story that will help change mental health in our industry for the better. As McKay put it, “This effort is beyond any one organization and working together to divide the rocks that are in this pack so that we all carry a little bit is critical and key. Because while what we each do might seem like only a little on its own, if we’re all doing it we will move that ball downfield, bit by bit.”

Industry experts discuss how increased awareness and tight labor markets are driving a shift toward coating restoration systems. 

Roof coating restoration is gaining momentum as building owners and specifiers look for cost-effective, less disruptive ways to extend roof life. In a recent episode of CoatingsCast™, industry experts from KARNAK and Clarity Roof Consulting discussed how accessibility to information and evolving project expectations are driving this trend. 

According to Chris Huettig of KARNAK, demand for coating systems is increasingly influenced by more informed building owners. “It’s driven from the top down,” he said. “Building owners are more educated and have questions that they’re bringing to specifiers.” That shift is leading many to consider restoration over replacement, particularly when evaluating cost, speed and business disruption. Coating systems can often be installed faster and with smaller crews, making them an attractive option in a tight labor market. 

Dan King of Clarity Roof Consulting agreed, acknowledging a broader change in how roofs are viewed. “There's more information percolating,” he said. “There’s been a change in looking at your roof as just a cost item to seeing it as an asset.” That mindset encourages more strategic decision-making, where restoration can offer long-term value when aligned with building performance goals. 

From the specifier side, Dan emphasized the importance of being a trusted partner for property owners to achieve a successful joint outcome. “In our role, we have really been able to open conversations based on trust with our clients,” Dan stated. “We work transparently, we build that trust and we breed success. Then, you can start to look at the value of different solutions. If you don't have that shared knowledge, you end up being more risk averse.” 

The panelists also highlighted the importance of collaboration and access to reliable information when navigating codes, regulations and system selection. “There's subject matter expertise held in manufacturing,” Dan said. “We go to fire marshals, we go to code officials, SPRI, RCMA, NRCA, RoofersCoffeeShop®. I find the ICC codes library really helpful.” Establishing relationships with these industry staples and leveraging the available resources help contractors and specifiers stay informed and deliver quality, compliant projects.  

As labor constraints persist and owners seek greater return on investment, coating restoration is positioned as a practical solution that balances performance, efficiency and cost.
