Once you determine the function of a roof coating, you must also consider the type of roof system you have that is going to be coated. Roof coating suppliers and manufacturers (like Conklin) generally offer two types of coatings: all-purpose, which are suitable for a range of substrates, and application-specific which tailored to one type or a limited range of substrates.
It is important to know that different substrates require different roof coatings. For example, it is more difficult for coatings to adhere to hard, smooth, chemically-inert surfaces, and much easier on rough, irregular, chemically-active surfaces.
Roof coating adhesion to a particular substrate improves when the installer applies a primer or base coat. Manufacturers like Conklin recommend very specific base coats (or primers) to match a specific top coat with a specific substrate. The installing roofing contractor should use only the base coat or primer specified by the coating manufacturer.
Coating primers and base coats for built-up roofs offer some very good examples. Manufacturers have designed products specifically to work on these surfaces - they work well on these often-hot surfaces by bonding to the asphalt and preventing it from bleeding into the white topcoat.
Enhancing the sustainability of a coated roof requires re-coating periodically to extend its service life. Most roof coatings are field-applied, and success depends on real-world conditions as well as the skill of the installer. To ensure proper curing, an experienced roofing contractor should pay careful attention to consistent application and changing weather conditions.
If you are considering a roof coating for your home or commercial building, make sure to ask the contractor why they are specifying the coating(s) being quoted and if that particular material is best suited for your roof.
