16 Gambrel Truss Plans for Homeowners and Builders

Gambrel truss plans are a great option for homeowners and builders looking to create a unique and functional space. These plans typically feature a distinctive double-pitched roof with two slopes on each side.

A gambrel roof can add visual interest and character to a home. The plans can also be customized to fit different architectural styles and budgets.

The 16 gambrel truss plans we'll be exploring offer a range of options for homeowners and builders. From simple to complex designs, there's something for everyone.

Cut the necessary number of truss pieces with 22 1/2 degree angles on each end and a length of “H” along the long side.

First, you'll need to cut all the truss pieces, which are identical. This will ensure that your truss is symmetrical and sturdy.

Next, mark and cut OSB web pieces by placing a 6×12 piece of OSB under the joint where the ends meet. Make sure it’s symmetrical.

You'll also need to mark along the top of both truss pieces with a pencil, then remove the OSB piece. This will help you get the right measurements for your OSB web pieces.

Cut along the marked lines and use this piece as a template to mark and cut the rest of the OSB web pieces.

Assemble half trusses by placing truss pieces in the jig and attaching the OSB web with 6 to 8 (1 3/4in) nails or screws into each side.

You can use glue or construction adhesive for extra strength to ensure a solid bond.

Before removing the first truss, place a pencil mark on the floor at the outside edge of the joint to serve as a reference point for the rest of the trusses.

Assemble half trusses by placing truss pieces in the jig and attaching the OSB web with 6 to 8 (1 3/4in) nails or screws into each side. This will help ensure a strong and sturdy truss assembly.

Before you remove the first truss, place a pencil mark on the floor at the outside edge of the joint. This mark will serve as a reference point to check if all further trusses match up correctly.

To ensure consistency in your truss assemblies, it's essential to follow a systematic approach. Mark the outside of the joint on the floor to use as a check for the rest of the trusses.

Here's a summary of the materials needed for the trusses:

Remember to use glue or construction adhesive for extra strength in your truss assemblies.

When assembling the trusses, there are specific instructions to follow for the last two trusses.

For all trusses except the last two, you'll want to leave the OSB webbing intact.

The last two trusses will be the gambrel end trusses, which means they'll need to be prepared differently.

These trusses will be used to attach the siding, so it's essential to leave the OSB webbing off the back side of the last two trusses.

This will provide a clear surface for nailing the siding, ensuring a secure and even attachment.

If you're looking to build a 12×16 gambrel barn shed, it's essential to have a clear estimate of the materials and costs involved. You can download a free PDF version of the cost estimate worksheet to print out and fill in the prices for each item.

The worksheet breaks down the materials into 17 categories, including lumber, siding, and fasteners. For example, you'll need 6 pieces of 4x4x8ft pressure-treated lumber and 51 pieces of 2x4x92 5/8 (PC) lumber.

Here's a breakdown of the lumber needed:

You can use this list to take down to your local building supply store to calculate the cost of building the shed. Additionally, you'll need to factor in the cost of felt paper, shingles, and assorted fasteners, which are estimated to be around $25.00.
