COATINGSPRO ROOF COATINGS 2016 29 metal roofs), and flashings should be inspected and notated. On low-slope roofing, a moisture scan, such as infrared, nuclear, or other method, should be used to determine if the roof is holding moisture. Saturated insulation should be removed and replaced, but this can add to the cost of a coating significantly. e rule of thumb is that anything over 20 percent of saturation across the roof makes the project economically unviable for coating restoration. e extent of improper repair materials, dirt, debris, or other laitance that exists will also add to the price to prepare the roof for coating. Taking this into account, the labor involved in a complete tear-off and re-roof is significantly more expensive than coating prep and installation. Often, the cost of a coating is less than a re-cover, depending on the amount of prep work required. Another item to note with the customer is that International Building Code will not allow a structure to have more than two roofs. W hen the life of a second roof is complete, both roofs must be torn off, down to the deck, and replaced with a new roof; however, this rule does not apply to roof coatings. Since they are considered a maintenance product, they are a very responsible option for structures with two existing roofs. Many times, roof coatings may be maintained and warranted by the manufacturer for the entire remaining life of the building. On top of all of the savings from the cost of installation, building owners should ask their accountants about the tax benefits of roof coatings. Since they are considered a mainte- nance item, it is often permissible for the customer to write off the full amount of the coating installation in the same year. 2. Coatings are wildly effective. ere is no doubt about it: I have seen the black eyes that bad installations have given the roof coating market. I have seen roof coatings peel up, turn brittle, crack into pieces, and lose adhesion. I don't blame anyone who has been burned in this way to be gun-shy when presented with another coating option for his or her roof. On the other hand, I would not feel comfortable letting my customers miss out on the benefits of a properly installed system because of a bad experience in the past. Millions upon millions of square feet of roofing have been coated and re-coated, and performed as promised. When applied correctly, roof coatings are completely seamless. Unlike traditional roofing products, which rely on heat-welded seams or sealants to hold the sheets together, roof coatings are monolithic. is trait makes them perfect for protecting the roof underneath from ultraviolet (UV) degrada- tion, water penetration, and other environmental stressors. Roof coatings are also elastomeric. is just means that Roof coatings can be less expensive than other roof solutions. Cost savings from the installation as well as tax benefits are two potential items to share with the facility owner. Marketing Roof Coating Systems
