It weighs 3 Ibs per one square footage of asphalt shingle
Roofing shingles weight between 200 & 250 lbs per square. 1 square = 3 bundles. So if you know how many square of shingles are on a house, you will know about how much the roofing debris will weigh.
Depends on the type of shingle (asphalt, shake, slate, etc.). Most asphalt shingles weigh about 75lbs/bundle, at 3 bundles per square (100 square feet per square).
It will depend on the weight per 100 square feet of shingle coverage. In the U.S., the average weight per 100 square feet will be in the range of 240 pounds, and the normal number of bundles it takes to cover 100 square feet is 3. With these rough approximations, 100 bundles would weigh 8,000 pounds, or 4 tons.
The pros and the cons of tin roofing weigh each other out. While tin roofing may be more aesthetically pleasing than shingles made out of wood, it does have a propensity towards rust and could cause problems for home-owners down the line.

It is a known fact that Metal roofs are durable, fire retardant and almost maintenance-free. They are also energy efficient; metal reflects heat and blocks its transfer into the attic. Research by the Florida Solar Energy Center in 1985 showed that metal absorbed 34 percent less heat than asphalt shingles, and homeowners switching to metal roofing reported saving up to 20 percent on their energy bills. Everyone needs to save as much as they can nowadays. Steel roofs offer other environmental benefits as well. They are made from between 60 percent to 65 percent recyclable material. Because they weigh very little, metal roofing can be installed over existing roofs, eliminating the need to dispose of excess material in a landfill.
