A Weighty Subject

My husband and I want to install 1" X 4" T&G beaded carsiding on the ceiling of our detached garage which seems to be a very solid structure and was built in the 1890's. We have taken off the garage doors and spanned a large header system across the front that anchors the side walls. There is a loft that has boards that rest on the top plate on three sides of the garage and nail into the rafters. We are putting V-groove carsiding on the walls which we are hoping will also add to the stability of the building. We removed the rotted shakes from the roof but left the board sheathing. We then put 1/2" plywood sheathing over the board sheathing and applied shingles. Our question is: Should we be concerned with the weight of the beadboard carsiding that we want to put on the ceiling? We certainly don't want the weight to splay the walls and have everything come crashing down. Everything "appears" tied together but we can't tell how much weight the building can withstand. Thanks!

Without looking at the structure, it seems unlikely beadboard added to the ceiling would cause a collapse.
Well constructed in 1890 should still be well constructed today as long as their isn't rot or insect damage.
If you've added a loft with heavy storage & wonder about the added load, have an engineer run some calclations. It shouldn't be that hard to do yourself if you understand or learn how to calculate the dead & live loads & then check span charts. The over nominal dimensions of the old lumber would be a bit of a safety factor with todays lumber sizes.

Thank you for your quick response. We did not add the loft. It was built in the original design. We do not plan to use the loft as a living space, merely a storage place. But, there would still be weight in the storage items. We would like to think that they planned on the walls carrying extra weight since the loft was original. We don't know anything about calculating weight but we will try to research that out. Thank you for letting us know about that. We appreciate your time. Thank you!
