Roof Coating vs. Roof Paint: PROS and CONS
Posted on April 30, 2023 by Phillip Camerer
When it comes to protecting a roof from the elements, you have two main options:
- Roof coatings
- Roof paints
There are differences between the two, despite the similarities. Roof coating is a thicker material applied in layers to create a protective barrier against moisture and UV rays. Roof paint, on the other hand, is a thinner liquid that gets applied in one or two coats to give your roof a new look.
There are two common types of roof resurfacing material.
- Elastomeric Roof Coating
- Acrylic Roof Paint
Elastomeric roof coatings provide an extra layer of protection against extreme weather conditions. In contrast, acrylic roof paints are designed for roofs with flat surfaces and provide excellent coverage and durability that can hold up in adverse weather conditions.
Elastomeric Roof Coating Pros and Cons
A roof coat is one of the most effective solutions. Elastomeric coating is a proven flat roof membrane, sometimes referred to as a modified bitumen.
Many of these benefits can protect the roof of your home or business:
- Increased energy efficiency
- Improved longevity
- UV protection
Whether you’re looking for an elastomeric or a reflective roof coating, there are many advantages to using either type of product. Elastomeric roofing material also has its benefits, which make it an attractive option for homeowners and business owners. But when it comes to a reflective roof coating, it’s designed to reflect more sunlight and absorb less solar energy.
Elastomeric paints are expensive compared to other options and may require up to 50% more money. However, it covers the same space but in a thicker finish, increasing your expenses. Some other cons include the following:
- Cumbersome Product Descriptions
- Difficult Application
- Peeling and Permeation
Incorrect application can lead to thin, fragile coatings that quickly come off. Water can also affect elastomeric coating, causing it to thin and peel. However, if you hire an experienced roofing contractor, they can provide a durable waterproof sealant that will exceed any warranty.
For these reasons, not every elastomeric coating you see is the right choice for the job. It’s also recommended that homeowners and businesses read the warranty to get a better idea of what is covered before proceeding with a purchase.
Acrylic Roof Paint Pros and Cons
Roof paint, in contrast, is a great way to protect and enhance your home’s curb appeal. As a bonus, it may also increase the value of your property.
Acrylic paint is a popular choice for roof painting, as it offers several advantages over other types of paint, including:
- Easy application
- Excellent adhesion
- Resistance to fading and chalking
Additionally, acrylic paint on roofs can reduce energy costs as an extra layer of insulation against heat and cold air. Furthermore, it’s a popular choice for its adhesive sealant on roofs, which provides additional protection from water damage and other elements.
Although a popular choice for its return value to homeowners, acrylic paint has several cons, which include:
- Ponding Water
- Negative Results in Cold Temperature Applications
- Loss of Mil Thickness
Acrylic roof coatings get compromised if exposed to pooled water. Building owners and managers should consult with a roofing specialist before deciding on an acrylic roofing system or product to avoid this problem. That way, they can ensure that the roof structure won’t be negatively affected by any ponding water issues.
Acrylic coatings are a water-based product and must be applied when the temperature outside is at least 50°F or warmer. Otherwise, it won’t stick properly to the roofing substrate in colder weather.
Acrylic roofing systems may experience a decrease in mil thickness due to the elements, and it is essential to research the product before purchase. Ensure it’s rigorously tested for environmental conditions specific to the roofing application results you seek.
