Local climate is a big consideration when selecting materials for a roof replacement project. Ideally, you should pick a roofing material that isn’t vulnerable to the sun’s UV rays. If your roofing materials are not UV-resistant, it shouldn’t come as a surprise to see them damaged or breaking down at some point.
In this article, Fields Roof Service lists some of the harmful effects of UV radiation on roofing materials. We also share some basic information about acrylic elastomeric coatings and how they can protect against UV.
Effects of UV on Roofing Materials
UV degradation typically affects a number of natural and synthetic polymers including some types of rubber, neoprene and polyvinyl chloride (PVC). If these materials receive excessive exposure to UV, they can experience the following issues:
- fading color
- becoming less flexible
- losing strength
- cracking
Because of this vulnerability, these materials will likely need a higher level of roof maintenance. Consult a roofing professional to know the best way to care for such materials.
Additionally, certain types of inks and dyes can be affected too. This type of damage, which is often called photodegradation or photo rendering, causes materials like textile and polymers to change or fade in color or produce a chalky surface.
Acrylic Elastomeric Coatings
Acrylic elastomeric roof coatings are a liquid-applied monolithic membrane that fully adheres and is formed in situ on the roof. These coatings are typically 5 to 10 times thicker than the paint used in homes. Since this type of coating is applied as a liquid and it forms a tough membrane as it dries, it has no seams that you need to worry about. It offers two benefits: 1) it reduces temperature and 2) its UV blocking properties reduce the risk of premature degradation and deterioration of the roofing membrane.
