What You Should Know About Roof Coating

Having your commercial roof coated is an excellent way to elongate its life, as it adds a thick layer of protection. Alternatively, you can also use roof coatings to fix small areas of damage or wear instead of replacing the entire roof.

What Are Roof Coating Benefits?

Covering your commercial roof with a coating adds more benefits than simply extending the life of the roof or patching damage. Some of the benefits associated with roof coating include:

Prevents most roof leaks from occurring
Improves the aesthetics of the roof
Helps lower energy costs
Reduces the transfer of heat into the building

If you do a side-by-side roof coating comparison, you'll see that there are many different types of roof coatings. However, the benefits of using coatings primarily apply across the board, regardless of type used.

What Types of Roofs Are Eligible for Coating?

Roof coating is typically recommended for commercial roofs as opposed to residential applications. However, there are many types of commercial roofing that coatings are ideal for, such as:

Built-up asphalt roofs: Coatings work well to reduce heat transfer on these hot roofs, which can exceed very high temperatures on a hot day.
Mod-bit roofs: These types have a tendency to get moisture trapped in the roof, and a good coating prevents this from happening.
Concrete roofs: A coating is ideal to fill fractures and hairline cracks that happen with concrete.
Metal or rusted metal roofs: A protective coating prevents damage from occurring, and for rusted metal roofs, it can prevent rust from progressing any further.
EPDM rubber roofs: This type of roof can wear with age, similarly to a rubber tire. Coating restores this type of roof.

What Types of Roof Coatings Are There?

There are many different types of roof coatings that can benefit different types of roofs. For example, acrylic works well for metal and polyurethane is ideal for rubber roofs. Reading silicone roof coating reviews and roof coating reviews can help you make an informed choice. Coatings include:

Acrylic, which is ideal for metal
Butyl, which works for foam or metal applications
Polyurethane, which is an ideal pick for rubber or EPDM
Silicone, which is a versatile choice that works with many roof styles

Repairing Patches

Depending on the type of roof you're working on, using a coating is ideal for both smaller repairs and as a protective coating for an entire roof. You can use coatings to stop leaks, repair hairline cracks and damage, coat worn rubber or stop rust from forming. You'll have the coating applied as you normally would, but can have the contractor concentrate solely on the area of damage.

When Should Coating Be Applied?

Whether you use a professional or are applying the coating yourself, you want to make sure that conditions are ideal in order to apply the coating. Ideally, you want an outside temperature of 50 degrees Fahrenheit, with no pending rain in the forecast. Solvent-type coatings can be applied in colder weather. If there's pooling water in the area you wish to coat, it's best to check with the manufacturer before use; some coatings don't apply well over standing water. Overall, you can expect the coating to dry in roughly 24 hours, but this can be affected by the elements, humidity, wind and other factors.
