Grueling Winter Problems Affecting The Temperature to Apply Roof Coating on Metal Roofs in Denver CO

It's never easy when your metal roofs get into trouble in the middle of winter. Unfortunately, even the best roofing materials such as metal roofs cannot withstand a truly brutal winter storm. When the storm clears, your reliable and experienced Denver CO roofing contractor may refuse your work request and for good reason: their equipment and team cannot function properly during winter. You're left with one choice, and that's to use acrylic and know the temperature to apply roof coating on your roof effectively.

True enough, metal roof coating isn't rocket science. However, knowing the right temperature to apply roof coating is important. Winter's sub-zero temperatures can cool down and harden your coating without warning. At this point, it does seem like a bad idea, but if you know the freezing point of all types of coating, you may have a chance to re-coat your metal roof effectively. American Weather Star has an excellent article about this -- there's an excerpt that may interest you below.

The Right Temperature to Apply Roof Coating During Winter

Working with roof coatings in winter months can be slightly challenging. Since the chemistry of each roof coating will react a little differently in cold weather, we will address the cold weather concerns for the materials that compose our core systems.


Acrylic coatings make up our Met-A-Gard and Met-A-Gard+ roof coating systems. Acrylic 211, High-Tensile Acrylic 211, Butter-Grade 221 and Red Oxide Primer 912 are the key components of these high-performance roof restoration systems.

As water-based products, they will freeze when left in below freezing temperatures for an extended period of time. Once frozen, even after they have thawed, these products can no longer be used for effective roof coating restorations.

A warehouse that reaches 30-32 °F will not cause a problem but if it will be much cooler you will need to move to a heated area. During application make sure that it is 50°F and rising. The dry time of acrylic coatings will slow down dramatically if the air temperature is below 50°F.

If freezing may not be a concern, dew that comes in this time of year can cause major problems with the coating while still wet. Humidity is just as important to acrylic coatings as temperature. The higher the humidity the more reason for concern. (Continue Reading)

How To Apply Roof Coatings During Cold Seasons?

Always check weather conditions before application and never apply if rain is anticipated within 24 to 48 hours.

Air temperatures should be at a minimum of 55˚F with temperatures expected to rise for the following 24 hours. This includes temperatures during nighttime.

Apply the roof coating system in the early morning, finishing early into the afternoon to allow for a minimum of four hours of sunlight for the coating or sealants to cure.

Areas such as California, Hawaii, Texas, Arizona and Florida often have warm winter temperatures averaging between 60˚F to 90˚F in January. As long as these temperatures do not drop below 55˚F during the evening and rain is not expected, these weather conditions are acceptable for installing a roof coating system during the winter.
