Structural engineers look at the specifics of your construction and determine precisely how much weight your joists and trusses can support. I always thought they just ensured a bridge didn’t collapse or a building didn’t slide down the back of a hill. When in doubt, go light on the weight you’re storing up there.īefore I bought my first house, I’d never heard of using a structural engineer for a residential home. Don’t look at the advertised weight capacity and think your ceiling can automatically support that. How much weight your roof can hold before it caves in is a totally different question. Manufacturers of overhead garage storage only care about how much weight their product can hold before IT breaks. Monkey Bar Storage and Topp Rax are just a couple manufacturers that have this option. This will give it extra support and eliminate any flexing and shaking. Look for an overhead storage rack that also mounts to the wall studs. That’s great in an earthquake, but not when stuff is hanging over your car. That means it can flex and bend as the weight on it shifts. Most DIY overhead storage I’ve seen on Amazon is only mounted to the ceiling and hangs down from thin metal support brackets. It will be much weaker than if you installed it over multiple joists. Never mount your ceiling brackets along the length of a single joist. Most support beams will run horizontally across the width of your garage (parallel to your garage door). The most important thing you can do when installing overhead storage is to spread the weight load over as many trusses or joists as possible.
What Kind of Ceiling Do You Have in Your Garage? That’s great news because floor joists are built to withstand more weight than a ceiling truss.īut just what is the difference between trusses and joists? So instead of ceiling joists in my garage, I have the trusses supporting the second floor as my garage ceiling. In my case, I have a two-story home with my master bedroom directly above the garage. This varies by the span of the joist and the size, grade, and species of lumber used.

Ceilings in single-story homes are only designed to support a constant load of 5 lbs/SqFt., plus a live load of 10 lbs/SqFt.

However, how your home’s ceiling was constructed impacts how much weight you can hang from it.Īccording to the International Residential Code (IRC), lower-level ceilings in multi-story homes are designed to support a minimum constant load of 20 lbs/SqFt, including the weight of the floor above it, plus a live load of 30 lbs/SqFt. However, it’s good to know how much weight you can safely hang from your garage ceiling before you do.Īfter all, you don’t want everything falling down on my car or your head if you’re in the garage at the time. One of the best ways to open up some extra space in your garage is to put as much as possible in overhead storage.
