4 Barn Truss Maintenance Tips

If you have a barn truss, then there are a few different types of things that you can do to try to keep it lasting for as long as possible. The maintenance for a barn truss is something that is not very difficult and can be done pretty easily as long as you stay on top of the task. Not regularly performing the maintenance can lead to you having to completely take down the truss and rebuild a new one.

Keep It Clean

Like with most things that need to be maintained, you will need to make sure that your barn truss is kept clean. This is something that may be a little bit difficult to do because of its location. You will need to use a pressure washer to clean your barn truss every so often. Typically, spring is a good time, especially after a particularly hard winter. This is when the truss will need the most amount of maintenance. You can rent a pressure washer at most home improvement stores and save on the cost of a full purchase.

Paint It

It is a really good idea for you to keep your barn truss maintained by keeping the paint on it new and fresh. While this is something that you will not need to do on a yearly basis (hopefully), you may still want to make sure that you check the condition of the paint every so often. Use a paint that is tough and can withstand the weather and the sun beating down on it for long periods of time. The paint can help to protect your barn truss from getting too worn out whenever there is inclement weather. Look for paints designed for exterior use to get the best protection.

Make Repairs Quickly

It is a good idea, at least once or twice a year, to take the time to get a close look at your barn truss. Use a ladder to get up close to the truss and make sure that there are no rotted pieces that are extremely damaged, as these can end up ruining the entire structure of the barn truss. The sooner that you notice an issue with the damaged pieces, the less time they will have had to ruin any other pieces. Remember that rot and mold can spread and end up doing a lot of damage very quickly if they are not removed promptly and correctly. You can find spray solutions that will inhibit the growth of damaging mold and mildew at any home improvement retailer. These should be applied every couple of years.


The best thing that you can do in terms of maintenance happens before you even build your barn truss. Make sure that you use really good and solid materials. This is something that may cost a little bit more up front, but it is going to really save you money and headaches later down the road.
