Roof coatings are vital to repair roofs and increasing their service life, but there is more to it than choosing the best coating. Managers in maintenance and engineering should also consider the coating’s lifespan after it has been applied. Roof coatings can be a fluid-applied, fully adherent membrane or a non-membrane material. As long as their tensile strength and elastic limit are not exceeded, they can be stretched and restored to their original shape without being permanently deformed. These two features, breathability (the ability to release moisture and water), UV reflectivity (the ability to block the sun’s rays), and permeability, are crucial for managers to consider when specifying the best product for the work. Managers may better define available products to meet facility demands and train to assure excellent installation and a long performance life if they have a firm grasp of the costs and benefits of roof coatings.
Managers can handle the issue of providing a roof with extended performance life and sustainability at optimal cost with the help of roof coatings. When it comes to roofing, sustainability implies addressing the needs of the present and those of the future. To achieve sustainability, managers may need to reassess current roof management strategies if they result in material waste, pollution, higher costs, and diminished future supply. Compared to installing a whole new roof, the cost of applying a coating is minimal.
Since roof coatings can be put directly over an existing roof, the job can often be completed in a single day without any tear-off. In addition, overlays can have their lifespans prolonged by having coatings on top of them.
Unlike the cost of a new installation, which must be amortized over several years, the cost of roof coatings can typically be written off as an expense in the same year it is installed. Financial guidance should be sought to ensure that the organization reaps the full benefits of this current opportunity.
Managers need to determine which attributes are most relevant for their particular installation, rank the coatings in order of preference, and then define the layer or combination of coatings that provide the best service.
Synthetic rubber has exceptional durability. Elongation at a break of 1,100 percent, the tensile strength of 700 pounds per square inch, and moisture absorption of 0.1 perms are all associated with a 60 to 80 mils thickness. The lower the number, the better the protection against water and dampness. Synthetic rubber is black in color, long-lasting, renewable, impermeable to air, and resistant to ponding and hail.
Using non-destructive testing, workers can ensure they meet rating coverage requirements and coating life. The deck must be prepared following the manufacturer’s instructions based on industry codes. The deck is dry enough for painting when measured using a moisture meter. Samples with a standard surface roughness can be used as a benchmark for determining what kind of bonding is required. Coating dry thickness is accurately measured with thickness meters.
When specified, applied, and maintained correctly, roof coatings can extend the life of a roof by 20 years. Quality control procedures should begin with education and exploration, then progress to study of the roof, product choice, installation, and upkeep.
Regardless of the length of any applicable warranties, a properly trained team is the key to enduring success in these areas. Training time at each level of this process can easily exceed 500 hours. In-house and contract installers need training that includes knowledge of product limits and compatibility with the roofing on which coatings are placed for the best results.
The success of a roof coating project depends on every step being carried out safely that maximizes the benefits with minimal waste, and this can only be achieved via proper training. No smoking is allowed where combustible items are handled or stored, certain materials become slippery when wet, and all employees must wear protective gear.
Managers can learn all about roof coating from a variety of resources. Some movies are free online or packaged with the device; the manufacturer or contractor can provide others. Both in-person and online learning options are readily available. Roof coating application is a complex task that requires several hours of training to assure quality and cost benefits; therefore, this investment is well worth it.
In conclusion, an extraordinarily extended roof life can be achieved by following a maintenance plan outline with specific due dates for each phase. Here’s a sample maintenance schedule for the first decade after application:
The best performance and durability from a coating can be achieved by following the codes and manufacturer’s recommendations. Meeting the code standards for a coating’s life cycle is accomplished by following the manufacturer’s recommendations based on destructive testing. The specifier is responsible for ensuring that all items meet all applicable regulations.
