What is the Cost to Replace the Metal Roof on a Barn?

Brenda Priddy

Replacing a metal barn roof is something that must be done at some point. Over the years, even metal roofs break down and leak. If a roof was not originally well-designed, replacing the roof with quality metal becomes even more important. The cost of replacing the roof is a large concern.

In many cases the cost is the largest determining factor in what sort of roof is chosen.


When replacing a metal roof there are many expenditures in addition to the cost of the metal. The cost of the metal will depend on the type of metal used and how large the barn is. Most sorts of metal roofing cost anywhere from $1.80 to $6 per square foot. This does not include additional materials such as tools and insulation. Many contractors will include the price of these items with their estimates, but if the barn is a DIY project, then the cost of materials becomes more important.


There are several different types of metal that can be used to replace a barn roof. The original form of metal barn roofing is made from tin. This is the least expensive form of metal roofing. However, a tin roof will have to be replaced sooner than other sorts of metal roofs. Steel roofing is a heavier form of metal roofing. It usually costs anywhere from $2 to $4 per square foot depending on the finish and style of the shingles. Copper shingles are the most expensive, running anywhere from $4 to $6 per square foot of roofing. Aluminum shingles are usually anywhere from $1.25 to $3 per square foot.


The size of the barn also plays a large part in the cost of the roof replacement. Larger barns are going to cost more to recover than smaller barns. This is not only because of the metal costs. Labor, additional materials, insulation and even the pitch of the roof can all play a part in the final cost, and that will vary depending on the size of the barn. The size of the metal shingles is also a cost factor.


Whether or not you decide to replace the roof yourself will have a big effect on the price of the roof replacement. Roofing contractors will offer prices based on multiple factors, including what sort of roofing material will be used, if there are existing problems to the roof, how tall the roof is, how many people will be necessary to complete the job and how long the project will take. If the roof replacement will be done as DIY, then the labor costs will not be an issue.


There are many things to consider when replacing the roof of a barn. The weight of the roof plays an important role in how long the roof will last and what sorts of roofing can be used for a particular structure. Metal roofs are generally considered light-weight roofs, and so they can often be used where other roof types cannot. The weight of most metal roofs is anywhere from 50 to 150 pounds per 100 square feet. It is also important to consider the whole life of the roof. It might be better to purchase a more expensive kind of metal roof that will last longer through storms rather than the least expensive sort of metal that will have to be repaired or replaced much sooner.
