Testing Method
We had each product applied to a test panel at a commercial metal roofing contractor, following the manufacturer’s instructions. The contractors used airless spray equipment with 0.017-inch needles and 0.015-inch tips to apply the coatings.
We used a spray bottle to apply water to the test panels at 15-minute intervals over a 24-hour period, which allowed the coatings to cure and the rain to soak in. The next day, we checked each panel for rust spots, flaking, and peeling, as well as color retention.
We also checked the panels for wet-out, or how evenly the coatings covered the surface of the panel. Finally, we checked the coating’s adhesion: Was it easy to remove a small piece of the coating?

Considerations Before Making a Purchase
Durability
Before purchasing a rusty metal roof coating, it is important to consider the durability of the product. Look for a coating that is specially formulated for metal roofs and is designed to resist cracking, peeling, and fading. It should also be resistant to UV light, moisture, and extreme temperatures. This will ensure that the coating will last for many years.
Water Repellency
Another important factor to consider is the water repellency of the coating. Make sure that the product you purchase is designed to repel water and prevent water from penetrating the metal roof. This will help to protect the roof from rusting and other forms of damage.
VOCs
When purchasing a rusty metal roof coating, make sure that the product is low in Volatile Organic Compounds (VOCs). VOCs are harmful chemicals that can be released into the air when the product is applied. Look for a product that is low in VOCs and has been certified as safe for indoor and outdoor use.
Adhesion
The adhesion of the coating is another important factor to consider. Make sure that the product you purchase has strong adhesion to the metal surface, so it will stay in place and not peel or flake off. It should also be able to withstand extreme temperatures and weather conditions.
Ease of Application
Finally, look for a product that is easy to apply. Make sure that the coating is user-friendly, so you can apply it quickly and easily with minimal experience and effort.
What Can I Put on a Rusty Metal Roof?
When dealing with a rusty metal roof, the first step is to check for any structural damage. If there is any major damage, it is best to get it professionally repaired before proceeding. Once any repairs have been made, the next step is to clean the rusty metal roof.
This can be done with a pressure washer and a metal scrub brush. Once the roof is clean, it is important to apply a rust inhibitor, such as a water-based metal roof paint, to the surface. This will help prevent further rusting.
Make sure to allow the first coat of paint to dry thoroughly before applying a second coat. This process should be repeated until the desired color is achieved. With proper maintenance, the paint job should last for many years.
It is also important to keep an eye on the roof to make sure that no further rusting is occurring, and if it is, take the necessary steps to repair it.
How Do You Seal a Rusty Metal Roof?
Begin by examining the rusty metal roof for any holes or cracks that need to be repaired. Use a putty knife to spread a layer of urethane roof cement over the damaged area, ensuring that there is a surplus of 1 1/2 inches on all sides. If the damage is around rusted fasteners, be sure to include them in this repair.
Cut a piece of steel roofing mesh with tin snips to fit the size of the area needing repair. Place the mesh on top of the cement and press down firmly. Smooth the edges of the mesh with a putty knife.
Apply a second layer of roof cement over the mesh, ensuring that it is even and smooth. Allow the cement to fully dry and cure before using the roof. The repaired area should be completely sealed and rust-free.
Regularly check the roof to ensure that no additional damage has occurred and that the seal is still intact.
What Is the Best Paint for a Rusty Metal Roof?
Polyurethane coatings are the best paint to use on a rusty metal roof. They are designed to provide protection and durability, while also being resistant to impact and foot traffic. The polyurethane coatings are applied as a coating over existing roof membranes, and they provide superior protection against rust and corrosion.
They are also easy to apply and maintain, making them an economical choice for metal roofs. The polyurethane coatings are also aesthetically appealing and are available in a wide range of colors to suit any home or business. With the right preparation and application, polyurethane coatings can last for years and are an excellent choice for a rusty metal roof.
What Is the Best Coating to Put on a Metal Roof?
Metal roofs are popular due to their durability and longevity, but they can still suffer from corrosion and wear over time. To protect the roof and extend its life, a quality coating should be applied. The best coating to put on a metal roof is a silicone-based product.
This type of coating adheres well to the surface of the metal and is resistant to water and UV rays. It is also highly weather resistant and can withstand extreme temperatures. Additionally, this coating forms an impermeable barrier that prevents rust and corrosion, as well as protects against dirt, dust, and grime.
For added protection, a topcoat of acrylic or polyurethane can also be applied. Overall, silicone-based coatings are the best choice for metal roofs, as they offer superior protection and ensure the roof lasts for years to come.
What Is the Longest Lasting Roof Coating?
SPF roof coatings are the most durable roof protection available. Applied through the use of a spray gun, this material is made up of polyurethane foam and other compounds that create a strong, waterproof layer on top of the roof. With regular maintenance, this roof coating can last up to 50 years or more, making it an ideal choice for homeowners looking for long-term roof protection.
SPF roof coatings are also ideal for flat or low-slope roofs as they provide excellent protection from the elements. Additionally, SPF roof coatings are often less expensive than other types of roof coatings, making them a cost-effective choice. With its long-lasting protection and cost-effectiveness, SPF roof coatings remain one of the top choices in roof protection for homes in Fort Lauderdale and beyond.
Which Is Better Silicone or Elastomeric Roof Coating?
Silicone roof coating has many advantages when compared to elastomeric roof coating. Silicone coatings are highly resistant to both UV rays and moisture, making them more durable and long lasting. Additionally, they are typically more flexible than elastomeric coatings, which can be important in areas that experience extreme temperatures or large changes in temperature.
When it comes to adhesion, silicone coatings are superior to elastomeric coatings and tend to form a more uniform and stable bond. In terms of cost, silicone coatings are usually more expensive, but their longer life expectancy offsets this cost. Furthermore, silicone coatings are easier to apply and require no extra primers or solvents.
Overall, silicone roof coatings are the better option for most roofs, offering superior protection and longevity.
Should You Coat a Metal Roof?

Metal coatings are also very durable, weatherproof, and UV resistant, making them ideal for outdoor use.
Furthermore, metal roof coatings are relatively inexpensive and can be applied quickly, making them a great choice for those on a budget. All in all, coating a metal roof is a great option for those looking for an inexpensive, long-lasting roofing solution.

After this, you may need to use a primer to ensure the paint adheres properly. Finally, you can use either acrylic latex paint or a combination of oil-based alkyd paint and galvanized metal primer to give your roof a fresh coat of paint. Make sure to use a brush designed for metal roofs and to wear protective gear when handling the paint.
If done correctly, your metal roof should look as good as new.
