Roof coatings are applied on roofs to protect them from damaging effects of UV light, water and water. They help in extending the life and efficacy of the roofs.
We may see roofs all around us, but most of us do not realize the importance of a well-maintained roof for any house or building. However, as soon as there is some problem or inefficiency in our house or building roof we understand the importance of roofs and how important it is for them to function effectively.
Roofs are highly impacted by prolonged sun exposure, changing weather conditions and environmental fluctuations. When seasons change we change our wardrobe and dress according to the season to keep ourselves protected. But, unlike us, roofs do not get the required coverage for protection from damage.
Roof coatings provide an extra layer of protection to the roofs adding more years of life. Roof coatings help in extending the life and efficacy of the roofs.
Roof coatings involve repairing, patching, and coating the roof with an appropriate application. This roof coating service includes restoring and weatherproofing the roofing system enabling it to survive even the roughest of weather conditions.
Generally,the design of roof coatings allows it to expand and retract along with the roof materials in changing weather conditions. This helps the coating to remain adhered to the roof even in harsh conditions, thereby preventing any chances of rupturing the membrane.
Depending on the type of roof installed, one can expect a roof life of around 10, 20, 50 or even more years. The roof material, changing weather conditions are factors that can affect the life span of a roof.
What is a roof coating?
Roof coatings are applied on roofs to protect them from the damaging effects of UV light, water and water. They are thicker in consistency as compared to paint and have a higher solids content. They can provide protection for several years. They contain a high level of good quality resin making the coatingextremely elastic. The volume of resins in the coating allows the coating to maintain its elastic properties throughout its life cycle. Once cured, the resins create an elastomeric and durable film, providing a waterproofing effect. It also helpsfill up the small cracks and membrane seams present on the roofs.
What are the different types of roof coatings?
While restoring the roof system, you can choose fromthree types of roof coatings. The three main types of roof coatings are silicone coating, elastomeric coating, and acrylic coating.
While selecting the roof coating, you need to understand the difference in each formula. Study your roof, location, and slope, exposure to chemicals, heat, and UV rays and then determine the right type of roof coating for your roof.
- Silicone Coating
Silicone coatings are produced with a high solids’ dispersion of 100 percent silicone. It is a highly elastic material providing excellent bond and adhesion to the roof. Silicone coating offers excellent weather resistance. The coating rarely hardens or becomes brittle. This coating has the ability to withstand long-term exposure to ponding water which is not possible in other coatings.It providesvery good ultraviolet protection in extreme temperatures and is also oxidation-resistant. Silicone is available in different colors and is known to offer high reflectivity. A key feature of silicone roof coatings is that it is moisture-cured and eliminates the need for a primer.
- Acrylic Roof Coating
Acrylic is a water-based solution suitable for most roofs. Acrylic roof coatings are highly reflective and UV-resistant. Acrylic-based materials offer superb resistance to radiation and hail damage. They are inherently flexible and can easily withstand the dimensional instability of most roof membrane surfaces. Research has shown that properly formulated acrylic coatings can help reduce surface temperature by around 20 degrees F when exposed to direct sunlight at 85 degrees F.
- Elastomeric Roof Coatings
Thanks to its resilient formula, elastomeric roof coatings are able to withstand different weather conditions. They are comparatively cheaper than other roof coatings. They offer great reflectivity but are not UV stable as long as silicone is. Combining elastomeric coating with another coating makes it extremely durable.
How to Apply Roof Coating?
Before application of a roof coating, the roof needs to be prepared. The roof needs to be inspected for any damaged or worn sections or if any repairs are required. The roof is required to be pressure-washed to get rid of any residue. The coating cannot adhere properly to the roof if there is any residue on the roof.
Before the application of roof coating, a primer coat is applied to the roof. This will allow the coating to adhere better to the roof. Hire a professional roof coating services provider like Tucson Rubberized Roof Coating to apply roof coating to your roofs. Their knowledge and experience will ensure the coating stays for long and it protects the roof efficiently.
