How to Choose the Right Coating for a Commercial Flat Roof?

When someone says, “a roof over your head,” the initial implication is that they are referring to a place to live; also, the first picture that commonly comes to mind is the form of a peak, maybe with a vertical chimney stack jutting from one of the two sloping sides.

However, not all structures are private dwellings, and not every roof is designed with a pitch or slope. Flat roofing is a popular alternative for commercial projects such as retail malls, condos, office buildings, and multi-level parking structures owing to its many benefits. 

What to Think About When Choosing Commercial Roof Coatings

Whether you are constructing a new home, starting a new company, or renovating a commercial building’s roof, you will need to evaluate the roof’s current state, climate, and other considerations before deciding on the appropriate coating for your roof application. These elements, particularly the weather, will influence the sort of coating required to repair or restore your business roof. A structure in a dry, hot climate with a lot of sun exposure may need a different roof covering than a structure in a cold, snowy one.

Seasonal Variations and Weather Extremes

Seasons and temperature are indicators of the sort of damage your roof system may experience, and this informs the sort of coating your roof will need. It is important to consider how the seasons vary in your area as well as the sorts of weather extremes your roof will endure when selecting the correct business roof coating. Sun exposure, rainfall, and snowfall all contribute to the possibility of roof damage, which may be mitigated with the right roof coating.

The Existing Roof’s Condition

Before selecting a business roof coating, examine the state of your roof and the purpose of the new coating. Do you need to fix a particular issue with your current roof, such as corrosion, leaks, or alligatoring? Are you applying a coating on a brand-new roofing system that has not been damaged? Your responses will aid in determining the sort of coating to apply on your roof. 

Commercial Roof System Type

When selecting a restorative and protective coating, it is essential to consider the materials used on your roof, as well as its size and slope. These elements influence the sorts of damage that may occur on your roof. A metal roof, for example, would often leak due to expansion and contraction or rust from years of exposure to the weather, while a spray polyurethane foam roof can soon degrade due to sun exposure if not covered. You will want to choose a coating that provides the advantages and protection that your unique roof requires based on the kind and condition of your roofing system.
