Tin Roofing: How To Prevent And Repair Rust

Tin roofing isn't as commonly used as other forms of roofing these days (such as asphalt and tile), but it's still quite common to find on older homes and buildings. If your home has a tin roof, one problem you may have encountered is that of rust spots developing on the roof itself. Over time, if not repaired, rust can lead to corrosion, which will cause roof leaks. Fortunately, there are some steps homeowners can take to repair a rusty tin roof and prevent rust from becoming a repeated problem in the future.

Repairing Rusty Tin Roofing

The first step you'll need to take when it comes to repairing your rusty tin roof is to remove all traces of the rust; this can be done by carefully climbing onto your roof and using a wire brush to sand away the rusty spots. Be sure to wear gloves and goggles while scrubbing the rust away so as to protect yourself from possible injury. Once no more rust is visible, use a hose with a pressure wash setting to rinse off your roof and allow it to dry.

In the event that rust has already begun to corrode your roof, you'll need to patch it before you spray any water on it. This can be done by using urethane roofing cement to patch layers of metal mesh over the holes. For larger corrosion spots, you may need to replace the section of the roof entirely.

Preventing Rust On Tin Roofing

Once your roof is restored to the best possible condition, you'll want to take preventative measures to avoid rust and corrosion issues in the future. Contrary to what many homeowners believe, simply painting your tin roof won't protect it from rust. Instead, you'll need to use a primer that's rust-resistant and allow it to dry completely before covering it with a layer or two of a water-based paint that's specifically designed for use on metal roofing. By following these steps, your tin roof should be protected from rusting for several years before you'll need to re-prime and paint it again.

Having a tin roof at your home can require a little more maintenance than a traditional asphalt roof, but it is possible to protect and prolong the lifespan of your roof by following these steps. From there, you may be able to save yourself some money in roofing repairs and replacement down the road.
