Barn roofs are steep – that’s why they’re ideal for keeping out the rain, snow and even some types of bird poop (not really, but you didn’t hear that from me). Roofs such as these were once a vital part of everyday farm life and were especially useful to keep the hay in your barn nice and fresh. With a few simple tools and materials, you too can build a strong barn roof.
Building a barn roof is a complex process. It involves adhering to strict building codes, having knowledge of the materials involved, and extreme precision with the installation. There are numerous tutorials for constructing a barn roof online and even in books.

This is a guide for building a barn style roof with overhang. The process involves hanging 30 foot gambrel roof trusses and building a gambrel roof structure.
A barn style roof is one of the easiest and most common types of roofs to build. It consists of two sloped sides, each supported by a pair of trusses. A gable roof is another common type of barn roof, but it does not have a loft area like this design does. This article will show you how to build a barn style roof with overhang using 30 foot gambrel roof trusses.
There are many different ways to build a gambrel roof structure, but this method is very easy to understand and only requires basic carpentry skills. The first thing we’ll do is install our trusses, which will form the base for our structure. We’ll need 14′ long 2x10s for each side of the structure (a total of 28 boards), plus two additional pieces that will form an overhang on each side – these will be 16′ 2×6s cut in half lengthwise (so they’re 8′ long).
The gambrel roof is a popular choice for barns, and with good reason. It’s a simple design that can be adapted to suit a variety of situations. The following guide will show you how to build a barn-style roof with overhang and trusses, using only basic tools and materials.
How to build a barn roof
Building a barn roof can be a simple process, but it’s one that requires a good deal of planning. The first thing you’ll need to do is decide which type of roof you’re going to build.
There are two main types of barn roofs: hip and gambrel. A hip roof is one that slopes down in all directions from the top of the structure, while a gambrel roof slopes down on two sides and up on two sides. Both types have their advantages and disadvantages.
Hip Roofs
A hip roof is often considered the more traditional option for barns, and it works well if you have enough space on your property to accommodate such an expansive structure. Hip roofs also tend to be more energy efficient than gambrel roofs due to their ability to shed snow more easily during winter months. However, this style may not be ideal if you intend to use your barn as living space or if there are any other obstructions nearby that could obstruct sunlight from entering through windows or doors located on either side of the building’s front facade
Gambrel Roofs
A gambrel roof offers some advantages over a hip roof when it comes protecting livestock or equipment stored within its confines
Barn roof framing is a fairly simple structure. It’s basically a rectangle made of 2x4s (or larger lumber) with the bottom of the rectangle being on the ground and the top of the rectangle being where you want your roof to be.
There are two main types of barn roofs: hip roofs and gable roofs. A gable roof has a single ridge that runs across its peak, while a hip roof has two ridges that meet at right angles. Both are common in barns because they’re easy to build, stable and strong enough to withstand heavy snow loads.
To build a hip or gable barn roof, first decide what length of trusses you’ll need for your project. Trusses are long pieces of lumber that have been cut at an angle so they fit together like puzzle pieces to form triangles. They’re free-standing units that don’t need support from columns or posts.
There are many different sizes and styles of trusses available at home improvement stores or online retailers such as Amazon and eBay, but most people use either 30-foot or 36-foot lengths for their barn roofs. The average cost for these materials is around $1 per foot for smaller jobs (under 1,000 square feet), but can go

Attaching gambrel roof trusses can be a difficult task. The key to making the job easier is using the right type of gambrel roof brackets
The most common way to attach a gambrel roof truss is with a saddle hook. A saddle hook is basically a metal hook that connects the two rafters together. It’s important to use a saddle hook because it allows you to install the trusses quickly and easily, but it also allows for flexibility in case there are any problems later on down the road.
Building a gambrel roof offers a lot of benefits over gable roofs. It’s more aesthetically pleasing, easier to build, and provides more space inside the attic. The only downside is that it can be tricky to install trusses on a gambrel roof. The unique design makes it difficult to find standard trusses that will work properly.
The good news is there are some easy ways to make sure you get the right trusses for your project.
Here are some tips for choosing gambrel roof brackets:
Make sure they’re rated for your region’s climate zone
Just like any other part of your home, you want to choose gambrel roof brackets that will stand up against harsh weather conditions. You might have to spend more money upfront, but it will be worth it in the long run when you don’t have to replace them every year because they didn’t hold up.
Choose heavy-duty brackets if possible
While most brackets will hold up just fine under normal conditions, if you live in an area prone to high winds or storms (such as coastal areas), then you want something that’s going to withstand windy conditions without blowing over or bending out of shape too easily. When shopping around for brackets
The gambrel roof bracket is the most common type of bracket found on a barn. This bracket is made of steel and is designed to hold up large trusses. The brackets are usually attached to the trusses with lag bolts and washers. The length of the lag bolt depends on the thickness of the wood.
Gambrel Roof Brackets
The Gambrel roof is the most popular of the three roof types. It is a combination of a gable roof and a hip roof. The gable end of the house may be at either end, or both ends, or one end and not the other. This type of roof has several advantages over gable roofs, but it also has some disadvantages.
Gambrel Roof Advantages:
1) Provides more headroom in attic area than any other roof type (great for storage).
2) Provides more usable floor space than any other roof type (great for storage).
3) Can be built to last 50 years or more (as long as you don’t live in an area that gets hurricanes and tornadoes).
4) Has a lower slope than most hip roofs, so snow slides off easier than from most hip roofs (this is especially important if you live in an area that gets snow).
