While roofing tar is beneficial, it is essential to consider some precautions when using it. First, proper ventilation is crucial during application, as the fumes from roofing tar can be hazardous. Homeowners should also ensure that the roofing surface is clean and dry to achieve optimal adhesion. Finally, periodic inspections of the roof are recommended, as the effectiveness of roofing tar may diminish over time and may require reapplication.
