Tin roofing is usually coated with a thin layer of aluminum to protect it from the elements. When the coating starts to rust, the metal underneath is exposed and can cause extensive damage. If you notice rusty spots or flakes on your roof, it’s time to take action. In This Article we will deeply understand about Tin Roof Rusting.

What is Tin Roof Rusted?

Tin roof rusted means that the tin roofing has been corroded by the elements and is now in poor condition. This can occur due to weathering, acid rain, or salty air. The tin may start to flake off and lose its protective coating, exposing the steel beneath. This can lead to further corrosion, which in turn can cause the entire roof to fall down.

Types of Tin Roof

There are many different types of tin roofs and each has its own set of pros and cons. Here we’ll discuss the most common types.

1.    Sprayed-on Tin (SOT)

This type of roof is made up of numerous, small tin sheets that are sprayed onto a roof surface using a high-pressure water gun or a sprayer. The tin sheets are roughly one-half inch thick and overlap each other by about 1/8th of an inch.

The main advantage of Sprayed-on Tin (SOT) roof is that it’s cheaper to install than other types, and it doesn’t require special sealant for waterproofing. It also has the disadvantage of being less durable than other types, particularly if it’s subjected to heavy hail or rainstorms.

2.    Painted Tin (PT)

Like SOT roofs, PT roofs are made up of numerous, small tin sheets that are applied to a roof using a high-pressure water gun or sprayer. However, instead of being sprayed all at once, PT roofs are painted one section at a time by hand so that the seams between the individual sheets don’t show.

This type of roof is slightly more expensive than SOT roofs, but it’s also much more durable. PT roofs can stand up to Hail and Rainstorms better than SOT roofs because the individual metal sheets don’t overlap as much and there’s less chance for them to come in contact with one another. Additionally,  PT roofs can be painted any color, which makes them more versatile than SOT roofs.

3.    Asphalt Shingles (AS)

AS roofs are made up of dozens, or even hundreds, of small, flat sheets of asphalt that are spread over a roof surface using a trowel. Like PT roofs, AS roofs are more expensive than SOT and PS roofs, but they’re also much more durable.

AS roofs can withstand heavier hail and rainstorms than either SOT or PT roofs, and they’re also less likely to corrode or leak. However, AS roofs are not as versatile as PT or SOT roofs, because they only come in one color (usually black).

4.    Metal Roofs (MR)

The most popular type of tin roof, metal roofs, are made up of numerous, thick sheets of metal that are fastened to a roof surface using either nails or screws. Metal roofs are the most expensive type of tin roof and they’re also the most durable.

However, metal roofs are also the largest and most difficult type of tin roof to install. They require a lot of extra time and resources, and they’re not suitable for all types of roofs.

Why Does Tin-Roof Rust?

Tin roofs may rust because of various factors including exposure to the elements, improper maintenance, and corrosion. Tin tends to corrode more quickly than other metals, so a tin roof may be at risk for deterioration if left unprotected. The metal can also become corroded by acidic rain or water that has been polluted by chemicals or salt. Acid rain can attack the metal from the inside out, causing it to lose its strength and buckle. In severe cases, tin roofs may buckle and leak, creating serious safety hazards.

Importance of Tin Roof

A corroded tin roof can produce dangerous emissions that can include poisonous gasses and lead particles. In extreme cases, a tin roof may even collapse and cause serious injury. When a roof is in poor condition, it takes in water and humidity which causes the metal to rust.

Rust is an accumulation of iron oxide that forms on the surface of metal. This process makes metal soft, reduces its strength, and creates hazardous chemicals.

Tin roofs are a popular choice for decorative and weather-resistant roofing. They are also a cheap option, which is why they are used on a large scale.

Maintaining tin roof can be a costly and time-consuming process. It is important to contact a professional when any alarming sign of corrosion is detected, in order to avoid potential safety hazards.

Tin Roofs are Important for a variety of reasons.

  • First and foremost, they are very durable and can last for many years without rusting.
  • Secondly, a tin roof is an efficient conductor of heat and makes a great outdoor flooring option in summertime.
  • Finally, a tin roof provides excellent shade in the summertime and can be used to shelter an exterior wall from the sun.


When any alarming sign of corrosion is detected, it is important to contact a professional who can assess the condition and recommend corrective action.

How do I Replace my Tin Roof?

  2. Retrofit an existing roof with new material
    If your home doesn’t have a tin roof, you can still replace it with a new material. contractors can install new shingles, tiles, or metal panels on top of an existing roof. This can be a more cost-effective option than replacing the entire roof, but it may not be suitable for all homes.
