What Is the Most Effective Way to Prevent Roof Rust?

Roof rust typically happens when metallic elements of a roof are affected by rainwater. In most cases, metal roofs are at risk, but rust can also affect elements such as roof flashing, which are typically added to just about every type of sloped roof you can think of.

To prevent roof rust, you have to prevent the coating that protects the metal from being damaged or washed away. Most of the time, the coating will be affected by wind, hail, water and heat. However, any damage should be easily visible simply by climbing a ladder to the top of your roof and doing a quick visual inspection.

Depending on the extent of the damage, there can be various approaches to dealing with it. If a metal panel or shingle is damaged, it can simply be replaced. If the damage isn’t extensive, but there is rust set in, the rust can be scraped off and the affected area re-coated.

In some cases, you might find that there is rust in certain areas, while it hasn’t touched others. Replacing the affected shingles or flashing elements can help in this case, but it is also necessary to use preventive measures for dealing with the unaffected parts that no longer have a proper amount of coating protection. In many of these cases, it’s a good idea to contact one of your local Denver roofing companies, so they can make a valid assessment and suggest what course of action you should take.
