Roof Coatings Phoenix: Comparison between commercial Elastomeric Roof Coating and Aluminum Roof Coating
Commercial roofs are a vital part of any business and provide protection from heat and cold for its occupants. When constructing flat or low sloped roofing systems, contractors, architects and building owners are typically unaware of the important roll roof coatings can play in the performance of their new or existing roofing systems. Aluminum and elastomeric coatings are among the many varieties that are available today in the roofing industry. Roof Coatings Phoenix tell us that these coatings can help extend the life of a new or existing roof if applied properly on the top layer of a roof system to protect the roofing materials from the damaging effects of ultra violet light degradation and everyday weather conditions.
Benefits of roof coatings
Benefits of roof coatings
Coatings can deliver cost benefits no matter which type you use. Roof Coatings Phoenix says the important thing to remember is that they need to be applied professionally in the recommended manner to provide long term sustainable performance and a given value for the money invested. Commercial roof coatings help save on costs due to roof problems and avoid the disruption to a business that comes with replacing a roof due to damages caused by a failed roofing system. Coatings can typically be used to restore roofs made of metal, polyurethane foam, single ply, built-up and modified bitumen among others types. Among the widely used types of roof coatings are acrylic elastomer coatings and aluminum coatings. But how do you decide which type of roof coating is better and enduring?
Elastomeric commercial roof coating
Most elastomeric commercial roof coatings are a premium, water-based acrylic latex coating with superior elongation, tensile strength, ponded water and ultra violet light resistance. Properly applied, white elastomeric roof coatings can reflect up to 88% of sun’s heat and UV rays, lower roof and interior temperatures, prolong roof life, and reduces air conditioning usage and costs. But keep in mind, not all elastomerics are the same, elongation and tensile strength properties are often used by Roof Coatings Phoenix to promote one elastomeric coating over another. Unfortunately, a coating may yield different properties depending upon how the coating is formulated. What about low temperature properties? A coating that may provide satisfactory elongation in warm climates may not be suitable for colder climates. Moreover, a coating applied to a roofing substrate that is less dynamic, such as pre-cast concrete or metal roofing may perform satisfactorily. Thus, substrate dynamics must be considered when making a prudent choice.
Aluminum commercial roof coatings
Summer heat can severely distort many types of commercial roofs that have a built-up or modified bitumen roof and create splits, voids, and cracks in the surface of the existing roof. However, not all roofing systems can be coated with white elastomeric coating if they have been previously coated with aluminums. In most cases, aluminum coatings are typically used when trying to keep costs to a minimum. Though highly reflective, aluminum coatings do not provide the cooling effects and the reduced heat transfer in to the building structure of white elastomeric coatings. If you’re a building owner with an existing built-up or modified roof already coated with an aluminum this will be the best choice as aluminum coatings will bond well together than that of a white elastomer coatings. Aluminum coatings also work well for restoring existing metal roofs.
Here are two very important factors to consider when choosing and aluminum roof coating:
1. Some manufacturers incorporate rust inhibitors into their formulations to smother and prevent any further damage to rusted metal panels.
2. Some manufacturers have Energy Star certification.
Roof Coatings Phoenix states that this is another one of the many ways in which aluminum roof coatings help save you money. However, do your homework because not all aluminum coatings are created equal and these two factors can make a big difference in how well your aluminum coating performs.
