Commercial roofers in Indianapolis typically offer metal roofs pre-coated. However, this can fade over time, and it’s often a great idea to re-coat your metal roof to extend its lifespan and spruce up its appearance.
Our commercial roofing contractors in Indianapolis offer tips and guidance for when and how to coat a metal roof.
Re-Coating a Commercial Metal Roof 
Commercial roofing in Indianapolis can extend its lifespan significantly with re-coating. Common material options include galvanized or Galvalume steel – the latter especially is resistant to rust, but time and weather take their toll on any system.
A re-coating doesn’t just enhance the appearance of the system – it offers an extra decade or more of protection against the elements. This ensures that the roof will hold firm and be safe for commercial roofing contractors in Indianapolis to walk on when they perform maintenance, as well as minimizing the chance of leaks caused by corrosion.
As much commercial Indianapolis metal roofing is ridged or corrugated, a spray-on application tends to be the most effective technique, as rollers can miss gaps. For flatter models, rollers are a cost-effective way to apply a gorgeous new coating.
Re-Coating a Residential Metal Roof
Homes protected by a metal roof in Indianapolis can look forward to decades of extra protection compared with conventional asphalt systems. Materials like copper, steel, zinc, and aluminum are popular choices that resist corrosion – however, refreshing the protective layer is still important.
For residential applications, commercial roofers in Indianapolis can recommend a wide variety of color options to freshen up the appearance of your residential property. It’s worth noting that new coating should only be applied if proper roof repair in Indianapolis has been maintained through the years – while you can save a lot of money by re-coating compared to replacing, there’s no point re-coating a roof that has been poorly maintained and left derelict.
Coating Applications Used by Commercial Roofers in Indianapolis
Roller and spray applications are the most common and effective ways to treat a metal roof and are favored for most Indianapolis metal roofing. Here’s how they work.
Roller Coatings
The roller method is cheap and works well for flat roofs. Panels and tiles can be effectively treated using this method and its main goal is to enhance the appearance of the building and protect against rust. It’s also preferred for many larger applications.
Spray Coatings
The spray method is very common and works best for residential roofs and systems that a roller would struggle to cover completely. It’s also the most appropriate for steep slopes, as it’s easier to apply when using fall protection.
Color Considerations
White and light colors are perhaps the most popular color choice, as they reflect sunlight and look great. However, a huge range of color options is available for Indianapolis metal roofing.
