Without knowing how the roof was constructed and with what dimension of lumber or steel, there is no way to estimate.
100 lbs
Most roof racks have a total capacity or around 165 pounds.
Care must be taken in calculating the roof weight of a floating storage tank. The amount of weight per square foot is the most important measurement and must take into account the fluid nature of the whatever is being stored. Checking the ability of the roof to hold the weight is another important fact to not overlook.
The liner panel for a Butler roof system will support the weight of several weighing up to 300 pounds and their equipment during the erecting of a roof system. Safety standards require that the structure be able to hold at least one ton of weight.

I might be wrong to whoever reads this, but I think a house-top carpenter is a person who replaces or makes the roof of a house. The carpenter might build the trusses that hold up the roof. A roofer is the person who puts the roof covering (tar paper, shingles, etc.) on top of the trusses.
A load-bearing wall in a house is a wall that supports the weight of the structure above it. It is usually positioned in a way that helps distribute the weight of the roof and upper floors to the foundation of the house.

For a 1999 Suburban (so likely also applies to 94-98 models as well) the max load on the roof rack is 200#.
I have a 1999 Grand Cherokee with the standard roof bars, the maximum limit recommended in the owners manual is 68Kg or 150ibs.
