Today’s blog post takes a look at the merits of installing a fully adhered roof system on a commercial building. We start by examining what a fully adhered roof system is, and then proceed to examine the benefits it provides. We conclude by looking at this system in the context of a multi-ply spray foam roof system.
What is a Fully Adhered Roof?

Roofing professionals note it is best to adhere the membrane product to an insulation system. In most cases, commercial roofing contractors will use insulation cover board. When covering areas with angle changes, such as locations around rooftop units, walls, or curbs, the roof membrane is fastened and adhered for more effective long-term anchoring.
Building product manufacturers tend to give fully adhered roof systems the highest ratings for wind resistance. However, third party testing authority Factory Mutual assigns its highest wind ratings to mechanically fastened roof systems. Factory Mutual puts a higher premium on mechanically fastened roof systems in this performance measure since they are easily secured in weak points such as areas around a roof’s corners or perimeters.

Despite concerns about wind uplift, a fully adhered roof has many benefits that offer value. Full adherence is particularly a regularly-used method for securing single-ply roofing systems to commercial building overheads. Here are four quick benefits that explain why this roofing system is valuable:
- Fully adhered roof systems tend to have great aesthetic appeal.
Performance value, longevity, and long-term costs are all driving concerns for building architects and commercial construction professionals. But aesthetics is an important point of consideration as well. Other methods of securing a roof system to the substrate can be less appealing, as they make use of fasteners or ballast to keep the roof system anchored. The sight of many fasteners can disturb a commercial roof’s uniformity in its overall appearance. Moreover, ballast does not offer the flexibility for aesthetic concerns that full adherence can present. After all, the adhesive products that keep the roof membrane secured are hidden from view beneath the roof membrane’s surface.
- Fully adhered roofs tend to have little trouble with roof membrane fluttering.
The popular alternative to a fully adhered roof, a mechanically fastened roof, makes use of fasteners to keep the roofing membrane secure. But these fasteners do not account for as much square footage of the commercial roofing membrane as adhesive products do. Once an insulation system has been fastened onto a roof deck, in a fully adhered roof system every square foot of the membrane is secured to the insulation system. Because of the membrane’s stronger bonds to the insulation per square foot, the installed roof membrane tends not to flutter around as much when powerful winds roll around.
- Full roof adhesion is a time-tested roof securing method.
Innovations in the commercial construction sector have brought about many product novelties, such as cool roof coatings and their applications. Drawing from this wave of innovation, new methods for construction work like full roof adhesion arose in the 1960s. Fully adhered roofs specifically appeared in the mid-1960s, and ever since then full adhesion has become a time-proven method in the process of roof installation. Today, millions of square feet of fully adhered single-ply roofing systems have been installed. Many commercial building owners opt to have their roofs installed to the underlying substrate with this method due to fully adhered roofs’ performance value and track record of longevity, as seen in many single-ply roofs today.
The areas where a fully adhered system can begin peeling and then fail – namely the areas around roof perimeters, curbs, walls, and appliances—can be addressed by ensuring these areas stay strong and intact. Cutting down on opportunities for air infiltration into the roof system will also help—the seal-up of deck and wall interfaces are what is needed there.
Fully Adhered, Multi-Ply Conklin® Spray Polyurethane Foam System

Breaking it down, this multi-ply system is composed of:
- Spray polyurethane foam insulation system
- Base coat of roof coating product
- Fabric-embedded coating system
- Two layers of top-coat roof coating product
On top of being a fully adhered system, this multi-ply roof is made up of many alternating layers of fully adhered, monolithic roof coating and spray foam products. It is completely without seams, which makes it impervious to leaks, and it therefore offers many benefits:
- Significant tensile strength and exceptional durability
- Performance value equivalent to that of a multi-layered built-up roofing system
- Substantially improved wind resistance and greatly strengthened building structure provided by the multiple layers of roofing product applications
- Roof damage is localized and repairs are easily made
- Exceptionally long roof lifecycle—easily 40+ years or more—with proper roof maintenance and caretaking
- Strong-performing roof system that generates huge savings on cooling and heating costs year-round
- Completely seamless, completely waterproof, and fully adhered roof protection so leaks and other roof problems are kept at bay
- No lateral water travel possible with a multi-ply spray polyurethane foam system
- Easily applied on rooftops with challenging architectural designs or areas with difficult angle changes
- Backed by non-prorated warranty guarantee covering 100% of labor and material costs

Gone are the days when professionals rely solely on cold calling or print advertising to grow successful businesses; especially in highly competitive markets such as construction and roofing. Highly profitable companies today utilize niche-networking opportunities to attract a steady flow of fresh prospective customers. Companies subject to the ebb and flow of seasonal work can especially benefit from contacts made while networking with others.
The owner of KCI Roofing, a large residential roofing company that did as much as $12 million in annual sales with 25 salespeople before the great recession, found us online last month while researching the best way to enter the commercial roofing industry and within a few days decided to sign up himself and two of his best salespeople to go to this month’s roof systems warranty eligibility training classes.
Scott Hackney, owner of Bright Spot Wind and Solar, happens to be a personal friend of Jonathan Keim. He drove over 700 miles to be part of this month’s warranty training classes.
Dave Chwalibog of Spray Foam Systems also attended. We’ve been looking forward to meeting him for months and had a great time connecting over the two-day warranty training event and a great steakhouse dinner where we shared the best ways to grow in the commercial roofing market with everyone who attended the Conklin product training event.
Many entrepreneurs are attracted to the prospect of starting their own roofing business. But starting and running a roofing company can be demanding, and it is probably more suitable for people who like working with their hands or enjoy the rigors of the construction industry.

Generally speaking, repair costs can be difficult to estimate because they often vary according to roof system type. Factors such as how many appliances are on top of a building, a roof’s configuration, and a roof’s age, are also reasons for why roof repair costs differ on each building.
A study of buildings owned by Carnegie Mellon University provides insights into how much roof repairs can cost on multiple buildings over time. In the study, data gathered over nine years on 38 buildings in Carnegie Mellon University’s asset portfolio was used.
How much does a commercial roof replacement cost? One study reports on a roof with average dimensions of 10,000 square feet, a new commercial roof can cost over $42,500, or over $4.25 per square foot. That study also found 80% of the roofs tracked had been replaced before they needed to be.
One well-known study looked at commercial roof replacement costs over time. The study drew upon data collected over a space of 9 years. The study concentrated on lifecycle costs for low slope
