On the roofing market, there are a variety of coatings to choose from. Because the material compositions, uses, and application methods vary, contractors should consult the manufacturer’s material data sheets to identify which product is best for your home. An Atlanta roofing contractor knows very well that across all roof surfaces, not all coatings are appropriate or compatible.
Also, all pre-application protocols must be carried out following the roof coating manufacturer’s stipulations. It is a must to taking into account that proper on-site material storage is critical for all liquids and adhesives used in the roofing sector, and all of these materials have a shelf life.
Roof coatings are not the same as the underlying material used to construct a roof. Coatings are what keep your roof in good shape in the face of the elements. Roof coatings have several advantages, and here we share a few of them with you:
- Roof coatings can help protect your roof from harsh weather, particularly hail. Hailstones can wreak havoc on your roof, but roof coatings provide an extra layer of protection.
- A new roof can cost thousands of dollars. Roof coatings are often only 30% to 40% of the cost of a full tear-off.
- Roof coatings can help you save money on electricity by lowering the amount of energy required to chill your home. Since most of the roof coatings have reflecting qualities, they will reflect rather than absorb the ultraviolet (UV) rays that hit your roof and cause the increase of temperature within your home.
Here’s a rundown of some popular roof coating materials to consider for your roof:
Silicone Roof Coating
Silicone coatings are made from 100 percent silicone with high solids dispersion. It’s a highly flexible polymer with good adherence to existing surfaces. Silicones are resistant to the elements and rarely grow hard or brittle. In the past decade, silicone coatings have acquired a market share in the roofing industry.
The material’s capacity to endure long-term exposure to ponding water has led to an increase in applications, as most other coatings cannot withstand ponding water. In severe temperatures and harsh environments, silicone coatings also provide good UV protection and can withstand oxidation. Silicone comes in a wide range of colors and has good reflectivity and emissivity ratings.
Cost, application restrictions, and the fact that only a few materials – other than silicone – may be put directly to the silicone surface are some of the disadvantages. Silicone also attracts dirt and can lose its reflectivity over time.
Acrylic Roof Coatings
Acrylic coatings were originally used to protect sprayed urethane foam applications from the sun. Now, this type of coating can be found on a variety of roof membrane surfaces, including single-ply membranes and metal systems. Acrylic-based polymers have good radiation and hail protection, as well as the inherent flexibility necessary to overcome the dimensional instability of most roof membrane surfaces.
According to some studies, when exposed to direct sunshine at 85 degrees F, appropriately designed acrylic coatings can reduce the surface temperature by as much as 20 degrees F. Acrylic coatings are made entirely of acrylic and can be applied in a single or many coats. Please, be sure to remember that acrylic coatings should not be applied in temperatures below freezing or when precipitation is expected within a certain time frame after application.
Polyurethane Roof Coatings
Polyurethane coatings were designed to be placed over sprayed-in-place foam roofs initially. They are now applied as a coating to a range of existing roof membranes. Polyurethane coatings outperform all other coatings in terms of impact resistance and foot traffic. Currently, there are two types: aromatic and aliphatic polyurethane roof coatings. These products are usually used in conjunction with a base coat and a topcoat.
The base coat material is tough, but it doesn’t have a lot of UV protection, and since it is UV stable, keeps clean, and holds color longer than other coatings, the aliphatic coating is employed as a top surface.
Fluid-applied Asphaltic Rubber Membrane Roof Coating
An asphaltic rubber membrane system has been created which can be used for life extension repairs in cold-process fluid-applied applications. The asphaltic rubber material blends rubber’s elasticity with highly refined emulsified asphalt’s waterproof/weatherproof qualities. The resulting compositions are unique materials that form a monolithic, seamless rubber membrane that adheres completely to your roof and providing waterproofing-weatherproofing features.
