Why do barns look so different?
Barn design grew from need. Builders considered local weather, available timber and stone, the crops and animals on the farm, and traditions brought by settlers from other places. A barn in a snowy region may have a steep roof, while one in a hot place may favor ventilation.
Regional differences and family tradition also play a part. Because styles overlap and many barns have been altered, labels are guides and not strict categories.
Looking at barns from the road is a fine hobby. Notice the roof, the doors and the direction the barn faces, and compare with others nearby.
What are some common styles?
Many people recognize a few forms. Gable-roofed barns have a simple peaked roof. Gambrel roofs have two slopes on each side, giving more room in the loft. Bank barns are built into a hillside so that a ramp reaches the upper level. Round and polygonal barns are less common but striking.
Other forms include English-style barns, often with a central threshing floor, and large dairy and tobacco barns suited to specific crops. Local historians can tell you which forms are common in your county.
Walking a county road with a notebook can teach you more about local barn styles than any book, and neighbors usually enjoy sharing what they know about the barns they pass.
- Gable-roof barns with a simple peak
- Gambrel-roof barns with more loft space
- Bank barns built into a slope
- Round and many-sided barns
- Crop-specific barns for dairy, tobacco or hay
How do you read an old barn?
Look at the frame, the roof shape, the doors, the siding and the foundation. Hand-hewn timbers, pegged joints and saw marks can give clues to age and method. Additions, patches and filled openings tell the story of how use changed.
Do not climb into a weak structure. Old barns can have rotten floors, loose beams and hazards such as nests or sharp nails. If you are unsure, keep out and ask a professional.
Take photographs from the outside and record the location and any history the owner shares, which can become a useful record for a local historical society.
What about barn quilts, paint and signs?
Painted advertisements, quilt squares and weathered lettering are part of local culture. They show how barns served as billboards and community symbols. Ask the owner before you photograph or step onto private land.
If you want to paint or repair a historic barn, consult a preservation specialist first, since the wrong materials can damage old wood.
Many local groups document barns in their county, and they welcome volunteers who like to drive back roads.
How do you care for an old barn?
Water is the main enemy. Keep the roof sound, gutters clear and the ground sloped away from the foundation. Watch for leaning walls, sagging ridgelines and damaged sills, and tackle problems early.
Repair needs a skilled hand. Ask a qualified timber framer or preservation contractor, check references and get written estimates. Local building rules and permits vary by county.
Fire is a serious risk in barns full of hay and wiring. Ask a licensed electrician to check the wiring, and talk with your local fire department and insurance agent about safety and coverage.
Are there programs to help preserve barns?
Some states and local groups offer information, grants or tax programs for historic buildings. Availability changes, so ask your state historic preservation office and your county. Do not assume a program exists or that you qualify.
For financial or tax questions, ask a licensed accountant or attorney. Never rely on a stranger who promises money for your barn in exchange for a fee.
Ask about programs well before a roof fails, since applications can take time and funds are often limited.
What if the barn is no longer useful?
Some barns are too far gone to save, and some no longer fit the farm's needs. Before taking one down, consider alternatives such as repair, new uses or salvage. Ask a preservation office or local historical society whether it holds value for your community.
If you salvage lumber, be careful about lead paint and structural hazards. Contact your county health department and a licensed contractor for safe handling.
Documenting the barn with photographs and measurements before any change preserves its story even if the building does not stay.
