WHICH COATING IS RIGHT FOR YOUR ROOF?
Any time a building owner is considering a new roof coating for their roof, they have a tough choice to make between either acrylic or silicone roof coatings. At Progressive Materials, we are big fans of silicone coatings thanks to their superior performance, but there are some reasons why you might want to choose an acrylic. Let’s compare the two coatings.
Acrylic or Silicone?
The most common reason we hear as to why building owners choose acrylics when comparing between acrylic or silicone is that the material is less expensive. While this is generally true, per gallon acrylics do tend to be less expensive, the overall project cost is usually higher with an acrylic coating for two reasons:
The roof needs to be primed.
More material is required.
For most jobs, an acrylic coating has to go on thicker than a silicone coating – because it is an inferior product – which means you pay more for material on the job. You also tend to install acrylic coatings in 2 coats, meaning more material and more costly labor.
As you can see, acrylic isn’t really a less expensive product than silicone, it simply appears to be less expensive.
How Silicone Beats Acrylic
So how does a silicone coating outperform the competition in an acrylic or silicone scenario? Well, as you might guess, it rarely requires a primer and doesn’t require as many coats or as much material as an acrylic coating, but it also outperforms acrylic coatings once it’s installed on the roof.
Silicone coatings are also much more reflective than acrylic coatings, saving you money on energy. They leak less, last longer, and can resist ponding water, rather than crumbling when exposed to ponding water like an acrylic coating.
When Silicone Works Best
Silicone coatings are your best choice for a roof that is in good structural condition, but is either out of warranty or needs a “facelift”. In other words, the roof can still remain on the building without posing a safety threat, but it is leaking, sagging, or some other problem. As long as the roof is mostly dry, a silicone coating is a great fit for the building.
As you can see, silicone simply outperforms acrylic coatings in cost, ease of application, and performance once installed. Don’t be fooled by the “acrylic coatings are less expensive” rhetoric. Acrylic coatings are cheaper, but they aren’t less expensive.
