Roof Relief Vents

If roof relief vents are deemed appropriate they should be of a suitable type with minimum 4" flange and weather resistant hood, spaced 20' from roof edge perimeter and every 40' o.c. thereafter.

Proper Tools

To the professional roofer, the importance of proper tools is understood. However, here’s a brief recap of the ideal tools for applying Flintlastic modified bitumen:

  • For torch applications, a U.L. listed torch designed specifically for the application of modified bitumen membrane with U.L. listed high-pressure hose, and U.L. listed regulator. Use an appropriate length field torch for applying the field roof membrane, and a “detail” torch for accomplishing flashing details.

  • Propane tank with pressure gauge.

  • At least one ABC type fire extinguisher, fully charged (min. 20 lbs.) per each operating torch and the appropriate number of fire extinguishers at the kettle area if hot asphalt is used.

  • For hot asphalt applications, appropriate asphalt heating, handling and application equipment. Mop size should be not less than 32 ounces.

  • For self-adhering applications, 18" wide, 2"– 4" diameter industrial steel roller for pressing membrane into place; long-handled (standing) roller with 1/8" –1/4" nap for applying primer (1/8" nap for smooth surfaces, 1/4" nap for more porous surfaces); caulk gun for applying beads of FlintBond adhesive; hand-held hot air welding gun such as the Leister Triac™ (110 volt power required) or Primus Sievert PNS-4™ Hot Air Kit; seam probing tool to check for small voids.

  • A roofer’s hooked blade knife (the hooked blade is ideal for cutting the membrane).

  • A roofer’s trowel with beveled edges and rounded tip (allows smoothing of details without cutting or marking the membrane); trowels that allow adequate room between the roofer’s gloved fingers and the warm membrane are the best.

Proper Attire

  • Long pants and long sleeved shirts.
