Tips For Preventing Rust On The Roof

Posted on: 17 December 2017

If you have a metal roof or any roof with lots of metallic materials on it, then you need to be worried about the risk of rust or corrosion. Deal with your worries by taking the following measures for preventing roof rust:

Keep the Roof Clean

One of the most important steps to keeping your roof rust free is to keep it dry. This is because moisture accelerates rusting. You are probably wondering what this has to do with keeping the roof clean. Well, debris will keep your roof perpetually moist by not only attracting moisture but also prevent the roof from drying up. For example, if the snow melts on a clean roof, the water will flow down into the gutters and get channeled away. However, if the snow melts on a dirty roof, some of the water will soak into and get retained by the debris.

Ensure Proper Drainage

Poor roof drainage can also cause rust formation on the roof by keeping it continuously wet. This is particularly a problem with flat roofs where drainage cannot be left in the hands of gravity. The drainage system should ensure that water doesn't stand on the roof, for example when it rains, but get drained off as soon as possible.

Prevent Roof Leaks

Roof leaks can also lead to rust formation, especially inside the roof structure. In fact, this is probably the worst place rust can attack your roof because it will be hidden from view, and it can fester even for years without you knowing anything about it. As you know, rust weakens metal, which means corrosion inside the roof's structure can weaken your roof and lead to its premature demise.

Treat the Roof

There are different ways of treating the roof to reduce its susceptibility to rust; here are some of the common ones:


Rust occurs when the roof is exposed to oxygen, and water accelerates the process. Therefore, preventing metal from coming into contact with water and oxygen will prevent rusting. A good way of doing this is to paint the roof so that the paint covers the metal surface and prevents it from coming into contact with water and air.

Galvanize the Roofing Material

Galvanization is the process of coating metal with zinc. It has a protective feature because the zinc will protect the agents of rust (water and air) from reaching the metal below. Even if rusting has to occur, it will attack the zinc first before the metal it is protecting. There are galvanized roofing materials that you just install without further preparation.

If you already have lots of rust on the roof, then you need to have it inspected because rust can cause serious damage to the roof. Consult a roofing contractor, such as from National Roofing Of Collier Inc,
to determine whether this is the case and help you deal with the issue.
