Metal roofs are very durable even under extreme heat, torrential rains, high winds and hail. However, the overall longevity of a metal roof depends on the type of metal substrate, metallic layer and exterior coating.
Though the primary function of specialty exterior coatings is to protect metal roofs from direct exposure to UV radiation, rain water, moisture and other weather elements, even the best coating systems will eventually degrade in time. To avoid a complete roof replacement, it’s advisable to re-coat your metal roof at the first sign of deterioration, such as fading, chalking, cracking or peeling.
While re-coating isn’t a cure-all that can correct every roofing problem homeowners, building owners and facility managers encounter, it provides a series of advantages, among which the most essential one is cost effectiveness in the form of:
- Improved Performance Characteristics – Re-coating your metal roof goes beyond restoring it to a maintainable condition. Applying a specialty coating system will provide a durable, easy-to-maintain roofing membrane that enhances your roof’s characteristics, including UV resistance and rust/corrosion resistance. One notable aspect is that some coatings can be applied to existing rust. These products encapsulate rust, sealing minor imperfections like small cracks and holes, and keeping the roof weathertight. As long as the new coating is maintained in good condition, it will protect the metal substrate from further degradation.
- Increased roof life – When a metal roof is re-coated using proper metal preparation techniques along with the right products, and then maintained regularly, it can withstand years of abuse in the harsh climate of Florida. Since choosing the right products is critical to ensure long-lasting results, you need to consider the climate along with the current condition of your roof in conjunction with the technical characteristics of the product you intend to use. Today, the specialty coatings for metal roofs are divided into four main categories: acrylic, polyurethane, silicone and poly-vinylidene fluoride (PVDF) coatings. To maintain your roof in good condition and extend its service life, our professionals recommend re-coating it with an adequate, high-quality product every few years. The frequency at which your roof should be re-coated depends on the service life of the previous coating and weather conditions.
- Energy Savings – According to experts, a highly reflective coating system combined with proper attic insulation can save up to 50 percent in cooling costs during the hot Florida summers. These systems form a cool reflective layer, which reflects up to 80 percent of the sun’s rays back into the atmosphere. Not only will this prevent the metal roof surface from overheating, which reduces the thermal movement and prolongs your roof's lifespan; it will also improve indoor comfort, decrease air conditioning needs and reduce the energy bills. A cool roof coating may also bring you a series of tax advantages.
By re-coating your metal roof with the right product, you’re almost guaranteed to come out a winner. Besides enjoying great looks, solid protection and energy savings, re-coating your roof maximizes the market value of your home. Should you ever decide to sell it, you can get a higher price.
