You can help your roof last longer and stand up to the elements with the right roof sealant.

Type of Sealant
In general, there are two types of roof sealant—water-based and solvent-based. A water-based sealant is cost-effective and has no scent. However, it is not as durable as a solvent-based substance.
In the meantime, a solvent-based sealant can do a great job at holding up against the elements. However, it is typically more costly, heavier, and harder to apply.
Roof Sealant C5M Certification
Manufacturers score a roof sealant on a scale from C1 to C5. This scale identifies the ability of a roof sealant to survive the environment.
