I'm not sure how much a attic bear weighs but I've heard polar bears are about 1000 lbs

Thanks Jimbo. If my wife makes me go back up there I'm taking a tranquilizer gun with me

It must be noted that is you put any decking up there you should NOT crush the insulation, in fact there should ideally be air space between same.

You can use plywood or strand board, but to save weight and make it easy to get thru your attic stair opening if you go to HD have them cut the pieces into 3 equal parts about 16" x 96" and space them apart for air circulation and better coverage.

The garage has a span of about 20' so be mindful of that if anything is heavy, it is better to place that stuff over interior walls if you can for better support.

The first type light storage is design for 20 pounds per square foot (PSF) to the bottom chord.



The other type is a true attic truss for heavier loads upto about 35# per sq',

you can clearly see the bottom chord is bigger like a 2x6 or 2x8.

So if you have this type it can support more weight than the first type.



Bottom line don't overload spread out the boxes in my unprofessional "guess" you should be ok.

good info ,thanks

I was very concerned about the weight limits in my attic over the garage as I had lots of business stuff I'm required to keep for years. I ended up storing about 60 plastic tubs, each weighing between 50 and 75 lbs. So something between 3000 and 4500 lbs. Plus I added additional items over the joists on the wings. So far it's all been up there for about 6 weeks. When we had the big storms a couple of weeks ago I was expecting the to hear it crashing down as the house was moving. So far so good. So my unprofessional opinion would be either you can put a lot more up there than you think or I will be in big trouble soon. Hope it's the former.

My home inspector had said that the attic would hold a lot of weight. Today, I took another look, and I have the second type of truss system in jimbo's diagrams. Good to know.
