These traditional post and beam barn kits are inspired by the old high gable barns found near the Grand River in Michigan. High pitched barns are one of the oldest barn designs. Farmers of old needed a very steep pitched roof on their barns for a few reasons.
Rain Water tends to run off faster.
Many of the oldest gable barns had a thatched roof. Thatched roofs are basically a tight bundle of stiff straw. If rain water was allowed to sit on the roof it would eventually leak through. Therefore these barns needed to have a very high pitched roof so that rainwater would not sit and soak through.
The same is true today. Even though we have more advanced roofing products, they are still effected by the pitch of the roof. The longer water snow and ice can sit on a roof the faster the roofing material deteriorates. You don’t have to worry about that if you get a steep pitched roof like the barns in these kits have.
Your roof will last much longer.
Twice the storage space.
High gable barn roofs allow more space than what is found in your typical pole barn kits. Most pole barns come with a 4/12 pitch. Which simply means you have 4 feet of rise in 12 feet of width. For example if you have a 24’ wide barn with a 4/12 pitch you will have 4’ in height from the top of the wall to the peak in the roof.
Let me explain.
The peak (high point) of the gable roof is 12’ from the sidewall, and located at the center of the building. (half of 24’) Lets say your sidewall is 10’ then your peak would be 14’. If you have a 10/12 pitch on that same building then you have 10’ of height from the top of the sidewall to the peak on the same 24’ wide barn.
As a result you have more usable storage space. You can have the same size gable barn and have double the square footage of floor space. That 10’ of space coupled with our open timber truss design can be utilized by adding a full loft. Add a few dormers and you have an attractive usable living space.
The more upright your rafter timbers are the more strength they have.
Try this simple experiment to see for yourself.
You will need a popsicle stick, a table top or other stable flat surface, and some books. Place one book on the table. Now set the popsicle stick with one end on the edge of the book and the other end on the surface of the table. Now push down on the center of the popsicle stick and notice how hard you need to push on the stick to make it bend. Now stack another book on top or the first book. Move your popsicle stick end on that book and try it again. Then a another book.
Did you notice that it takes more force to bend the popsicle stick when you add more books?
This is because the flatter, or more horizontal the stick is, the more gravity is pulling the stick down therefore the less energy it takes to bend the stick.
It works the same way in a gable barn. The more vertical the timbers are, the less gravitational stress they are under. What this means for you is a stronger longer lasting roof support system.
I higher pitched gable roof allows more space for natural ventilation. Warm air rises to the peak of the barn and escapes through cupolas. This pulls cooler air into the barn. This cycle allows for a continuous fresh air supply. This is healthier for you and your animals. See our barn ventilation page for more information.
As you can see there are many advantages to a high pitched roof.
So why then are so many modern buildings built with a 4/12 pitch? There is only one reason. It is cheaper. The lower the roof pitch, the less material it takes to build it. After World War Two their was a sharp increase in the demand for cheap animal shelters and housing. Builders and truss manufacturers needed to find the cheapest methods they could get away with to build more houses and barns quickly. The 4/12 pitch was ideal for this. It was the minimum pitch they could use, just steep enough to prevent any big short term problems.
Of course that won’t work for you. You are not willing to sacrifice quality for a few dollars worth of materials. You want a barn that you can truly feel good about. You want a barn with real value.
