How Much Does Roof Coating Cost?
Roof coating is an excellent investment in the life of a roof. The cost to seal a roof ultimately depends on the amount of roof that needs to be covered and the labor costs, which vary from state to state. It is a fair expectation for businesses to expect to pay anywhere from a quarter to a dollar per square foot for professional installation. These amounts translate to roughly $375 to $1,500 for a typical 1,500 square-foot roof. Clear coating shingles and tiles are on the lower side of the price spectrum, and the cost to seal a flat roof is on the higher end of the same spectrum.
What is the Best Elastomeric Roof Coating?
To begin with, there are four different types of roof coating, each serving a slightly different need. Consult the following list for alternative roof coatings.
- Acrylic. Acrylic roof coating is best utilized and applied on over-sloped roofs. Butyl typically tends to be less popular than acrylic because it is more environmentally friendly and long-lasting.
- Butyl. This type of roof coating serves its best application for flat roof repair and low-sloping roofs. Single ply roofs and built-up PVC are excellent examples of roofs that benefit from butyl roof coatings.
- Polyurethane. It is conclusive; polyurethane is the best coating for EPDM rubber roofs. This coating does not require high PH rinses and the coating can be used on other single ply roofs.
- Silicone. For polyurethane foam roofs, this coating is optimal. It is very efficient for repairing weather and is also good for recoating roofs (particularly those with a silicone coating.)
Does Roof Coating Stop Leaks?
For serious roof repairs, a roof coating would only be a bandage instead of major surgery. Roofs with significant roof leaks should be appropriately diagnosed and treated by a professional roofing company. In order to truly address small leaks in a roof, the roof should be properly cleaned, repaired, and dried before an approved roof coating is applied. Coatings may be able to seal pinhole leaks, but should not be counted upon to do so. Roof treatments should be accurately managed and applied.
What Does Roof Coating Do?
Roof coating is a perfectly acceptable covering for a commercial flat roof. In fact, roof coatings are known to be a monolithic, fully adhered roofing membrane that is applied in liquid form. Many roof coatings are elastomeric, which means that they have elastic properties that allow them to stretch and return to their original shape without damage. When properly applied, roof coatings can be seamless, solving many roof problems. Many roofing contractors advise for property owners to invest in regular roof maintenance and repairs in addition to a necessary roof coating.
What is the Best Roof Paint?
In all fairness, there are a number of different roof coatings on the market. Selecting one will depend on the kind of roof one owns and the desired longevity of the coating. Commercial roof coatings come in a wide variety of formulations. These formulations include liquid copolymer rubber based formulas, acrylic low odor formulations, and more. In fact, a silicone liquid rubber roof coating exists for commercial buildings that are at risk for prolonged UV exposure and heat.
Roof Coating to Stop Leaks
Selecting a professional roofing company to assist with prevailing roof problems is an investment that will pay off handsome dividends. While roof coatings provide an incredible amount of benefits for commercial property owners, completely sealing roof leaks is a task best left to the professionals. Business owners typically should invest in roof maintenance once a year, with potential problems diagnosed and repaired as necessary. A new roof coating can be administered based upon need and urgency.
Roof Coating to Reduce Heat
Reflective heat coatings reduce heat transfer. Reflective roof coatings extend the life of the roof, decreasing thermal shock, and assist with mitigating leaks. While roof coatings alone will not correct leaks, they are designed to be part of the fundamental roofing process. Roof coatings also diminish thermal shock, which is the name of the phenomenon of thermal expansion and contraction of the roof membrane during temperature changes. A reflective roof coating will also diminish the heat load on the roofing assembly, decreasing the overall temperature.
While commercial business owners are considering ways to improve the efficiency of their building, a consideration in a carbon filtration system provides long term benefits. Water filtration ensures that everyone on a property will receive high-quality water from a purified supply.
Roof Coating for TPO
TPO roofs are acknowledged to be one of the hardest, most stubborn roofing substrates to adhere to. Most roof coating manufacturers need a primer for an etching rinse to be applied before even beginning to administer a base coat. Acrylic roof coatings offer the best solution in the roofing industry for restoring a TPO roof. This is because acrylic can tenaciously adhere to the TPO membrane. Additionally, there is no need to capture caustic contaminated water from primers and etching rinses, which is usually required by municipalities. This provides safer work conditions and is better for the environment.
Elastomeric Roof Coating vs. Silicone
It is important to note that the composition of the roof coating and the composition of the roof have many different chemical properties that will either bind horribly or balance terrifically. Silicone coatings utilize non-water solvents. This means that silicone roof coatings will cure in wetter areas more effectively. However, this property also renders them as highly flammable until they have completely dried. While silicone roof coatings are effective against water, they can get dirty and lose reflectivity up to 45% very quickly. Because silicone is slippery, be prepared to invest in only silicone roof repairs in the future.
