What is the best time to apply roof coating?

Best Time to Apply Roof Coating

As a homeowner, it is important to be proactive in caring for your home and ensuring it’s in good condition. One particularly important task to keep up with is roof maintenance, including the coating on your roof.

If left unchecked for too long, your roof may be dealing with problems that you won’t know about until the problem is severe, such as water seeping into the roof. The coating prevents such problems from threatening the building’s structural integrity and it’s advisable to coat your roof as a pre-emptive measure. 

But when is the best time to coat your roof? Can it be too hot or too cold to coat your roof? Continue reading for more information and then speak to your Local Roof Expert for an estimate or inspection.

Cool Coating Your Roof in Arizona

To answer the question of the best time to get your roof coated, let’s dive into what that even is. Elastomeric Coating, more commonly known as “Cool Coating” is a great option for your home in Arizona for many reasons.

Elastomeric roof sealers – acrylic, butyl, polyurethane, and silicone – are an incredibly thick yet flexible coating that creates a waterproof and weatherproof seal when applied to a roof. Cool Coating is a great option for homes and businesses in Arizona for multiple reasons including:

  • Cool Coat Systems are designed to keep water out while withstanding the sun, rain, and wind.
  • On Average, Cool Coating has a lower surface temperature than other kinds of roof systems, which results in lower Air Conditioning Bills and Electric Bills.
  • Compared to tile and shingle, a coated system is quite a bit easier to work on.
  • Elastomeric Coating is less expensive to apply than most other roofing systems.
  • In most cases, the coating itself will last for 3-6 years depending on variables of roof design, drainage, tree or plant debris, quality of the product, the technique of application, and patches that were done throughout its lifetime.

The Best Roof Coating in Arizona

Depending on the climate where you live, Cool Coating might be the best option for your residential or commercial property. That leaves two questions: what is the best Elastomeric Roof Coating and when is the best time to get it?

Elastomeric Roof Coating that is regionally produced or produced specifically for the climate you are living in is the best kind of coating to get. You’ll need to speak with a Professional Roofing Company to discuss the types they provide and installation. 

For example, Here at AA Brite in Tucson, AZ our favorite for the past 4 years or so has been Tucson Rubberized 7000. It provides maximum adhesion, strength, and elasticity to resist cracking and peeling while ensuring the highest grade of protection from extreme weather conditions. 

When is The Best Time to Get the Roof Coating Done?

The temperature has multiple effects but is not as significant as most people would think. In order for an elastomeric coating to be at its maximum strength and perform at the highest level, the liquids the manufacturer used to produce the cool coating need to be completely evaporated. If the process of evaporating was too fast or out of order then the coating can be compromised. Drying times and curing times are two different things.

Due to the property of Elastomeric Roof Coating, it’s best to apply when temperatures are above 60 Degrees Fahrenheit for the entire drying process (at least 8 hours after application). Residual moisture can affect the coating’s adhesion and take longer to dry, so there should be no chance of precipitation (rain, fog, humidity, or freezing temperates) for 24-48 hours after the application to allow the coating to dry correctly.

If you’re dealing with an Emergency Situation, it’s best to quickly contact a local roofing company to assess and assist you with your roof.

Can It Be Too Hot To Apply Roof Coating?

Yes, it can be too hot to apply roof coating. Especially for energy tan-colored roof coatings. The primary heat-related problem for new coating applications is blistering. As long as the material remains wet long enough to roll or brush out, then it’s fine. If it dries so fast that individual stripes are being painted instead of an area, then there will be edges on each brush stroke and there is a significant chance for blisters to form.

One cause of blistering is when the surface of a coating dries well before the interior of the coating does. This rapid drying traps liquid in the coating. Other than blistering, heat-related issues with new applications are rare.

Can It Be Too Cold To Apply Roof Coating?

Yes, it can be too cold to apply roof coating but this is not very often in Tucson, AZ. If the actual temperature of the roof, which is different than the ambient air temperature, is over thirty-five degrees and it’s not very humid and the roof is not freezing in the next six hours – then generally speaking it will be fine if premium materials were used.

If it’s cold and wet, then the material will take much longer to completely cure. While the cool coating is soft and curing, it’s vulnerable to being physically damaged. Elastomeric roof coatings can even be applied much thicker than normal and used to fill small ponding areas when it’s going to be cool out for long periods of time.
