I'm planning some renovations on my 1974 home, specifically raising the ceiling height on the second floor from 7.5 feet to 9 feet. Since my house has a flat roof, this will involve some extensive work like removing the roof and cutting into the walls. However, I'm not sure where to start, especially regarding the insulation between the roof and drywall ceiling, since there's no attic in my house. I'm worried about asbestos exposure and wonder if I should hire an asbestos inspector before any work begins. What steps should I take to ensure a safe renovation and avoid hiring a contractor who might inadvertently spread asbestos around?

You could buy an asbestos test kit online. It’s basically a box with ziplock bags where you put samples of insulation or plaster you're suspicious of. Then, just mail it to a testing company for results. Remember to wear an N95 mask when collecting samples to minimize dust. Stay tidy by cleaning up with a damp paper towel before taking off the mask, and make sure to wash your clothes afterward!
First, definitely test for asbestos! Also, keep in mind that renovations like this can be expensive, so make sure you're okay with investing in this project. Researching permit requirements is crucial since major structural changes often need stamped drawings. If you have a mortgage, be aware that your lender might be interested in this as well. Always hire licensed, insured contractors to minimize risks.
Start by hiring an architect to get a clear plan on how to modify the roof safely. After that, find a reputable construction company—they'll determine what’s needed for the job. Since the insulation needs to be removed and replaced, just keep in mind that you should clear the area and avoid it during the renovation. Just a heads up: this kind of work can get pretty pricey, so be prepared for that!

Before buying a kit, check for local testing labs. I got my results the next day from a lab nearby instead of waiting weeks for a mail-in kit.
