As building owners have increasingly realized the cost benefits of completing roof restorations rather than reroofing, the demand for roof coatings has similarly grown. The global coatings market stands at approximately $9 billion as of last year, and is projected to double by 2021. (These numbers were obtained from “Elastomeric Coating Market Worth 13.58 Billion USD by 2021,” which can be viewed here[2].) Roof and wall coatings certainly comprise a substantial portion of this.

Building owners are investing in roof assets more than ever, as roof coatings afford more options than the former protocol of doing nothing until complete tear-off. The emphasis on and demand for higher-quality coatings with longer life cycles has never been more prevalent. External factors such as the continued prominence of reflective coatings, legislation restricting volatile organic compounds (VOCs), and interest in sustainable products are also critical. As market trends and customer needs evolve, so too must the manufacturers who supply solutions.

Taking life cycle costs into account
Perhaps the paramount development in the coatings market in the past 10 years has been the shift from implementing short-term ‘quick fixes’ to longer-lasting and more cost-effective roofing solutions. Life cycle cost analyses have become an increasingly common and helpful resource for building owners and property managers—these decision-makers are realizing restoring a roof with a high-quality coating is more cost-effective in the long term than either reroofing or applying a lower-quality coating. The increased growth in the coatings market supports the trend of facility managers more proactively investing in their roof assets.

It is imperative to remember the initial cost of a roof is only a portion of the total cost of ownership over its lifespan. While cheaper coating options may initially save a few dollars, the inevitable recoating requirement in the next three to five years will be exponentially more costly in time, labour, and material. Given these additional costs, it is a much wiser decision to invest in a superior, more durable coating from the beginning—one that will be serviceable for a decade or longer.

Reflective coatings are dominating the marketplace
Another trend gaining momentum in the coatings industry is the increasing popularity of reflective—primarily white—coatings, as building owners begin to realize high-quality reflective coatings save money over their service lives through their reduction of energy costs. (An article on the growth of this trend in the United States, “Increasing Demand for Roof Coatings[4],” was published in April 2012.) In cooler climates, reflective coatings remain popular due to their crisp, sleek esthetic appeal, and can still offer owners some energy expenditure relief. These coatings—which are most often acrylics, polyurethanes, silicones, and polyvinylidene fluorides (PVDFs)—tend to be lower in VOCs than their bituminous-based counterparts, and can provide energy savings for building owners.

Reflective coatings are often seen as synonymous with white coatings, but they can also be aluminized. Both aluminized and white reflective coatings keep buildings cooler by protecting the roof from the sun’s harmful ultraviolet (UV) rays, and can aid in extending the service life of the entire building envelope. Coatings with reflective properties are also less vulnerable to drying out and cracking than coatings or roofs left with bare cap sheets, exposed asphalt, and even wall joint-sealants. Preventing such premature aging is the first step toward preventing leaks. As more data continues to compile citing the environmental and cost benefits of reflective roofs, their popularity will only continue to grow.

This roof uses a versatile liquid waterproofing membrane that maintains, restores, and upgrades the performance of single-ply metal, built-up roof (BUR), or modified roof systems.

Growing VOC regulations
In recent years, building owners and manufacturers alike have been affected by legislation restricting the allowable amount of VOCs—often referred to colloquially as solvents—in commercial construction products such as coatings. While the true long-term health and environmental effects of VOCs in coatings have been disputed, what cannot be denied is the inevitable nationwide limiting of allowable VOC content in residential and commercial construction products.  (An April 2008 article discussing VOC regulations in the United States, “What are VOCs in paint, and is more or less of them better?[6]”) With VOC regulations in the majority of provinces becoming stricter, the need for lower-emitting products has increased. (VOC regulations in most provinces mirror the state of California, which has the strictest regulations in the United States. For more on Canadian VOC rules, click here[7].) Manufacturers are now being forced to adjust to this new market factor, and will need to adapt to survive. The most successful roof coating manufacturers are beginning to formulate low-VOC alternative products in conjunction with their traditional offerings to satisfy the evolving needs and preferences of their customers, but as legislation becomes more strict, the differences between these types of products will gradually decrease.

Increasing demand for eco-friendly products
Working in conjunction with the two aforementioned market forces is newfound customer demand for more sustainable, environmentally responsible, and renewable products. This phenomenon has been a large driver in every major worldwide market (e.g. energy and technology), as well as in the manufacturing sector. (This information was obtained from an October 2015 report, “Renewables to Lead World Power Market Growth to 2020,[8]” from the International Energy Agency.)

Obviously, this trend lends itself to the increase in solar panel-laden roofs, but it is also beginning to impact the coatings market. Reflective coatings are an environmentally beneficial technology not necessarily new to the market, but ‘green’ coatings have the potential to take sustainability to a new level by incorporating bio-based or recycled content and decreasing the complete carbon footprint of the product’s life cycle, from manufacture to disposal. Customers, now more than ever, are demanding environmentally conscious products, and manufacturers who cannot meet this criterion will be missing out on a lucrative and loyal demographic.

Strategic innovation
A driver shaping virtually all industries—certainly including roof coatings—is the market variable of strategic innovation. Strategic innovation is the creation of corporate growth strategies, new product categories, services, or businesses that ‘change the game’ and generate significant new value for consumers and new revenue for the corporation. (For more, read “A Framework for Strategic Innovation[9].”) To revolutionize the marketplace and attain first-mover advantage, proactive manufacturers are perpetually developing products and systems addressing the changing needs of the consumer, including solutions to common headaches such as ponding water resistance, adhesion, reduction of application time/labour, and cost reduction. Largely due to the rapid growth and evolution of the market space in which they reside, roof-coating manufacturers are being incentivized more than ever to stress the importance of strategic innovation to short- and long-term success.

As roof coatings continue to grow in popularity and relevance, more manufacturers will enter the battle for market space, particularly in the rapidly expanding Canadian market. Informed building owners will benefit from this competition, and those who communicate regularly with local roofing professionals about these trends will find quality insight and recommendations are available for their unique needs.

As for manufacturers, the companies that succeed will be those who track and predict current and future market shifts, thus gaining the competitive advantage. (One method of doing this is to rely on industry organizations like the Roof Coatings Manufacturers Association [RCMA], of which this author is an active member. RCMA is a national trade association representing manufacturers of asphaltic and solar reflective roof coatings and industry suppliers. It promotes the benefits of roof coatings and provides members with up-to-date information on building codes and standards, technical developments, and other topics of interest.) If manufacturers continue to incorporate accurately predicted consumer behavior trends with strategic innovation, the future of the industry will be brighter than ever.
