JC, I'm in the process of removing asbestos shingles from my home. In most states, it is legal for a homeowner to remove the shingles themselves. No license is required. (If you are going to be paying someone to remove them, they have to be licensed. Expect to pay about $800 per 100 square feet, a huge sum of money!). Protect the ground with plastic and dropclothes to gather up falling pieces. Removed the first course of shingles from the bottom (you'll probably have to break them) and then remove the nails for each success course and pull off the shingles without breaking them. It's very easy. Be sure to wear gloves and a mask; in general, the asbestos that was used on residences is in a cement suspension and is not friable, so the risk is minimal. A trip to the library for some research about the hazards of asbestos is probably a good idea before getting too far into the project. Disposal is harder than removing them. Disposal must be at a certified landfill. The shingles must be wrapped in two layers of 6 mil poly before moving; then they can be brought to the landfill. In New Jersey, a 10 yard dumpster will cost about $800 to get rid of.
