Which device is used to dispense asphalt on a roofing job?

• A. Mini-Mopper
• B. Roofing hatchet
• C. Roller-type felt layer
• D. Slater's hammer

Answer: (A)

In built-up roofing, spreading a tack coat of hot asphalt onto the roof deck is a essential step before laying the felt. The mini-mopper is the tool designed specifically to dispense that hot asphalt in a controlled, even manner. Its small size lets you apply a thin, uniform layer precisely where you need it—around penetrations, edges, and tight spots—without waste. This even tack coat is what lets the felt bond properly to the deck and to subsequent asphalt and fabric layers. The other tools aren’t meant for dispensing asphalt. A roofing hatchet is a nail-driving and shingle-cutting tool used during installation, not for applying asphalt. A roller-type felt layer is used to press and embed the felt into the asphalt after an application has been laid, helping with adhesion but not primarily for dispensing the asphalt itself. A slater’s hammer is a slate-roofing tool used to trim and fasten slates, not for asphalt work.
