Disposing of solvent-based sealants also can be trickier, since they may be considered Household Hazardous Waste HHW and need to be disposed of at an appropriate facility. Within the two main categories, there are five types of roof sealants: acrylic, polyurethane, silicone, rubber, and sealant tape. A sealant with a C1 certification can only tolerate environments with minimal corrosive elements, like heated buildings with clean atmospheres.
A sealant with a C5 certification can tolerate highly corrosive environments, like buildings with high levels of condensation or humidity and high pollution. The C5 rating can be further divided into C5I for industrial settings, like factories with high humidity and pollution.
And C5M for marine settings like boats and docks exposed to high levels of moisture and salt. Every type of roof sealant will offer some protection against water, but not all are capable of producing a completely waterproof membrane. If your main goal is to waterproof your roof, the best sealant types are rubber, silicone, and polyurethane.
Regardless of the type of sealant used, multiple coats are often required to create a completely waterproof seal over your entire roof. The exception includes repairing small isolated leaks, where a single coat of most sealants will create a sufficient waterproof barrier. Rubber, acrylic, silicone, and polyurethane sealants all possess high levels of reflectivity. White and light colored sealants generally possess the highest reflectivity, while black and darker colored sealants offer the lowest amounts of reflectivity.
Sealant tapes will usually last this long without any special application process, but the longevity of liquid sealants depends on the thickness of the applied coating. Obtaining the proper thickness might require several coats of sealant, and sealant manufacturers will often specify the necessary amount of coats needed to obtain the desired thickness. Maintaining the performance includes inspecting the roof at least once a year under normal weather conditions and repairing any damage after adverse weather, like heavy rain, snow, and intense sun exposure.
Some sealant manufacturers and roofing contractors recommend resealing your roof every five years, regardless of its condition, to maximize longevity. Thicker, solvent-based sealants, like silicone and some rubber sealants, are harder to apply than water-based sealants, like acrylic and some water-based rubber sealants.
Also, thicker sealants may be easier to work with in hot weather, since thin sealants might become too runny to achieve a required thick coat. Both thick and thin sealants can be applied with a paint brush or roller, but with thinner sealants you have the additional option of using a paint sprayer. For isolated repair work, sealants in caulking tubes can more easily access nooks and crannies that would be difficult to reach with a brush, and sealant tapes can be easily applied to the affected area with minimal effort and no additional tools.
