Exterior durability is crucial when choosing a high performance elastomeric roof coating. Below is are two questions you should research before selecting a roof coating system for you building to guarantee excellent protection and long-lasting durability.
What kind of UV protection will the coating provide?
Go to the Cool Roof Rating Councils (CRRC) website to determine how reflective the elastomeric roof coating is based on initial and aged solar reflectance and thermal emittance values. The greater the number is for each of the values, the better! (Check out NCC’s roof coatings and systems that are listed with the CRRC.)
Highly reflective coatings are able to reflect a majority of the sun’s UV rays away from the building, back into the atmosphere, allowing the building to absorb only a very small percentage of the sun’s heat. When you choose a roof coating with excellent UV protection, your roof is safeguarded against its biggest enemy – ultraviolet rays aka the sun’s heat. Protection against UV rays allows your roofs lifespan to last longer, remain flexible for longer without becoming embrittled, and will lower roof maintenance costs.
Does it Protect Against Foot Traffic
Your roof needs to be accessed from time to time to perform routine maintenance checks, unclog drains, work on rooftop equipment (such as solar panels or HVAC equipment), and more. It is essential to choose an elastomeric roof coating that can withstand normal foot traffic while accessing these locations. There is an AcryShield A550 elastomeric roof coating that provides additional protection against foot traffic and physical abuse. A coating such as the A550 would be good to use directly around roof hatches and equipment that will be accessed regularly to ensure proper protection and durability.
The AcryShield elastomeric roof coating line offers excellent durability, UV resistance, and substrate protection from degradation from sunlight. These roof coatings even provide enhanced longevity and brightness (for maximum reflectivity) with superior dirt pick up resistance (allows the coating to remain white and reflect greater) and protection against biological attack such as algae and mold.
