Recoating your metal roof at appropriate intervals can be immensely beneficial and is arguably a necessity. Metal roofs are more expensive than architectural shingles but are a popular choice for homeowners who like the aesthetic and are looking for an energy-efficient roofing material. Although they can last a long time, their longevity can be cut short by neglect. Recoating can preserve the benefits metal roofing offers and ensure homeowners get the most out of their investment while spending less.

What Material Should Be Used to Recoat Metal Roofs?

Rubber, silicone and aluminum coatings suit metal roofs best. They provide a durable waterproofing membrane that can handle your roof’s expansion and contraction in certain weather conditions, offering superior protection against rust and cracking and enhancing the metal’s longevity. While most elastomeric coatings can work well with metal roofs, certain ones don’t. Water-based acrylic elastomeric coatings can help shield against leaks but are ineffective in preventing water pooling.

Benefits of Recoating Metal Roofs

Reduce Repairs: Recoating metal roofs can protect them from wear and tear, providing an extra layer of protection against storms, hail, high heat and other harmful weather conditions that can damage your roof. Recoating can limit roof repairs, which is particularly beneficial since metal roofs are more expensive to repair and replace than other roof types. As a result, recoating can safeguard its quality, saving you more in the long run.

Delay Replacement: Homeowners can also extend their roof’s lifespan by recoating, which delays the need for replacement. Roof replacement is one of the most expensive – yet eventually necessary – home improvement projects. Metal roofs are already beneficial in this regard, as they have a longer lifespan than other roof types. Most metal roofs perform optimally for 30 to 50 years, but with recoating and proper maintenance, metal roofs can last up to 70 years.

Increase Energy Efficiency: Adding another coat to your metal roof can limit heat gain. Roof coating is designed to reflect UV rays, cooling your roof and consequently your home, reducing reliance on your HVAC system. By conserving their energy usage, homeowners can save more on utilities while staying cool during the brutal Dallas summers.

Provide Water Sealant: Recoating gives additional coverage to more vulnerable areas of your roof that might be cracking, sagging or rusting, sealing any potential leaks and protecting your home from water damage.

Customizability: Recoating gives homeowners the opportunity to change their roof’s color, allowing them to shake up their home’s curbside appeal hassle-free without having to undergo an expensive overhaul that may involve replacing their roof.

How Often Should You Recoat Your Roof?

Typically, metal roofs should be recoated every five to 12 years, although your exact timeline will vary. Certain roof types can require more frequent recoating. Different roof coatings also have different lifespans – elastomeric coatings can last up to 18 years, while a silicone coating usually doesn’t last more than 10 years.

Texas homeowners will also have to recoat their roofs more often due to the state’s warmer climate. Excessive UV exposure can accelerate rusting, potentially compromising your roof’s structural integrity. At Billy Harris Roofing, we make each maintenance appointment worthwhile, applying multiple layers of recoating to give your roof long-lasting protection against Texas’s harsh weather conditions.

Can I Recoat My Own Metal Roof?

Recoating requires experience to do it correctly. While you technically can attempt it on your own, you risk spending a lot of money on materials and then getting subpar results with limited efficacy. Applying numerous coats while recoating is crucial for extending the job’s effectiveness. One coat tends to only last four years at most, while adding even just a second coat can keep the coating strong for another five to seven years. Not only do homeowners not have easy access to powerful coating materials, but they usually don’t have the training or experience to apply multiple coats properly.
