Tin Roof Insulation: Best Practices

Install a tin roof on your home or shed. This material is durable, lightweight and inexpensive. However, installation requires more than just nailing on the sheets of metal. You must add proper insulation so the structure can withstand different weather conditions.

Roof insulation is measured in terms of R-value. An insulation material with a higher R-value has better thermal resistance. Here are some roofing insulation options that are used for making tin roofs energy-efficient and noise-proof as well.

Foam Roof Insulation

This is one of the most popular types of insulation. Foam roof insulation is a product of polyurethane foam that is directly applied to the roof of a building. The foam is durable, rigid and is known to stop cold or heat from entering through the roof. This means that buildings with foam insulation do not require excess cooling or heating. You would be able to save a lot of money on your electricity bills.

Fiberglass Insulation

This type of insulation is not only used for tin roof but for other types of roofs as well. Fiberglass insulation is available in two types - fiberglass sheets that can be fixed as insulation to roofs from the inside and loose fibers that are mixed with adhesive. These are blown into place and help to make the tin roof energy efficient.

Cellulose Fiber

Another popular type of insulation is cellulose fiber. This type of insulation is slightly better than fiberglass insulation and offers you excellent quality for the price you pay. Cellulose fiber is generally treated with a flame-resistant chemical which makes it a much safer alternative than some of the other types of insulation materials.


Tin roofs are known to make a great deal of noise during rains and hailstones. The clatter that is produced when hailstones and rain fall on tin roofs can be quite annoying to live with. Fortunately, tin roofs can be insulated against these to provide a noise proof roof. Usually, plywood is installed first and the tin sheets are laid on top of the wood. The plywood absorbs the noise of the tin roof, ensuring that nothing can be heard on the underside. Plywood insulation is most commonly used for tin roofs.

These are the most popular insulation materials used for tin roofs. Besides these, there are many other types of insulation available. The important thing to remember when insulating tin roofs is that the insulation should withstand weather elements. So choosing the first thing you find is not a really good idea. Take into consideration your location and the type of weather that you experience first. This will help you decide on a type of tin roof insulation that will suit your needs perfectly.
