Roof coating is a monolithic, fully adhered, fluid applied roofing membrane. Many roof coatings are elastomeric, which means they have elastic properties that allow them to stretch and return to their original shape without damage. Roof coatings are used for roof types that collect water and debris, such as flat roofs. They are also used on other angled roof types as they age to protect from long term damage. Roof sealants make your roof more fire-resistant and help prevent the growth of mold and algae.
As an added benefit, reflective or white coatings can minimize solar gain and can reduce heating costs in the summer. Coatings extend the roof service life by reflecting harmful ultraviolet radiation away from the roof membrane. When a roof has been coated during installation, recoating is performed when the existing coating deteriorates and no longer protects the underlying membrane.
Conflict with Roofing Material
Seal coats may achieve the same objective as a replacement, if your roof is not yet at a point of failure. The average delivery wait time in the current market for EPDM, TPO, PVC and similar roofing materials is 5 to 6 months. All building trades are experiencing shortages in materials due to the shutdowns the pandemic caused. With fewer workers, the manufacturers cannot keep up with the demand. Furthermore, the raw materials that go into manufacturing roofing products are being held up at the ports.
Multiple suppliers have stated in the last month of price increases between 8 percent to 12 percent on multiple materials including shingles, TPO, PVC and others. In July of 2022, the price of these materials is expected to increase yet again at a rate of up to 18 percent. The Producer Price Index illustrates the severe price increases of 2021 of all raw materials. Asphalt products and accessories increased in price by 33 percent from 2018 and among the purchaser prices of industrial products, the prices of fuel and power increased by 30.0 percent, the prices of chemical raw materials increased by 17.9 percent, the prices of non-ferrous metal materials and wires increased by 17.4 percent, and the prices of ferrous metal materials increased by 9.8 percent. To avoid paying out-of-pocket to cover material price spikes, roofing professionals must plan for further price volatility in 2022. Choosing a seal coat and adding a roofing maintenance program will extend a roofing systems performance from 5 to 25 years.
