Flat roof torch down requires proper surface preparation, modified bitumen rolls, base sheets, flashing, edge metal, heat equipment, and experienced installation. The roof surface must be clean, dry, stable, and free from damaged materials before work begins.

Because this system uses heat during installation, safety and skill are extremely important. The contractor must properly bond the membrane, seal seams, protect roof edges, and secure areas around vents, drains, and walls. Correct slope, drainage, and flashing details are also required to prevent leaks and extend the life of the flat roof for reliable roof performance in demanding weather conditions year round.
