What is the best method to determine whether an existing building includes asbestos-containing roofing materials before the project?

Counting the number of doors in the building
Checking the exterior paint color
Analysis of test samples of existing roof materials
Measuring the height of the building

The correct answer is: Analysis of test samples of existing roof materials

The most effective way to determine if existing roofing materials contain asbestos is through the analysis of test samples taken from those materials. This method provides conclusive evidence regarding the presence of asbestos, as laboratory testing can accurately identify asbestos fibers within the sample. The other options lack a direct connection to identifying asbestos. Counting the number of doors in a building does not provide any information about roofing materials. Checking the exterior paint color is unrelated, as paint does not typically contain asbestos, particularly in roofing contexts. Measuring the height of the building also has no relevance to the roofing materials themselves. Therefore, conducting a material analysis is the only reliable approach for confirming the presence of asbestos in roofing.
