Depending on the type of debris, how much debris, and whether or not some of the roofing material (such as tiles) need to be removed in order to remove the debris. One of the most common ways debris is removed is to blow it from the roof, using a leaf blower. Although an attempt is made to control the debris as much as possible, it is not uncommon for the debris to sift into the attic or garage spaces, through skylights or vents, as well as litter the grounds.
