If you have rust on your metal roof, it has to be removed before holes that cause roofing leaks can form. If it’s already rusting, there are steps to remedy the problem.
Removing the RustBefore performing repairs or applying any kind of coating, rust must be removed. This involves climbing the roof so your safest and best option is to hire a professional. If you choose to remove it yourself, you should first inspect the roof and mark the rust spots. You don’t have to remove all of them, just the parts that are starting to flake. Use a pressure washer or a light sand blaster to remove the flaking rust. Make sure the roof is completely dry before proceeding with the next step.
Apply Protective CoatingYour metal roofing system needs protective coatings to prevent rust from returning. Coat the roof with a zinc primer according to the manufacturer’s instructions. A spray paint applicator can apply even coats and can help speed up the process. Make sure the primer is dry before applying a top coat. There are specialized roof paints that add reflectivity to the roof surface, which can help reduce the heat absorbed through the roof. Acrylic is a good alternative, but may be more difficult to apply.
Why Hire a Professional?Any kind of work is inherently dangerous. Painting a metal roof may sound simple, but considering the length of time you need to spend on the roof – removing the rust, applying multiple coats and waiting for each coat to dry – you’re risking your safety without proper safety equipment. Professionals are issued complete safety gear, trained to use it and insured in case of an accident.
There’s also the fact that professionals deliver professional results. Matching the color of the original roof is especially difficult to do if the original was a custom blend. If it requires a whole-roof application, professionals can finish the job faster. Some contractors even warrant their work against recurring rust formation.
