General Application Data: Roof replacement usually involves more complexities than new construction roofing. Often encountered are situations such as rusted/deteriorated decks, rotted wood components, rooftop equipment which cannot be moved or shut down, and numerous other conditions.
The following application information is designed to serve as a general guide. Your local Tremco Representative will prepare detailed specifications based upon your roof’s conditions.
Structural Deck: Must be properly designed and structurally sound.
Drainage: Ponding conditions are unacceptable and will adversely affect performance of any roofing system. If positive drainage does not exist, water removal must be facilitated by lowering drains, and/ or installing additional drains, tapered insulation, or Tremco approved lightweight insulating concrete slope system.
Insulation: Insulation must be dry and kept dry. No more insulation shall be installed than can be covered that day.
Installation Procedures: According to particular job specifications, prepare surface to be covered:
• Replace areas of wet insulation, deteriorated deck, and wood components.
• Install roof insulation or base sheet.
Plan placement of THERMglass Type IV Roofing Ply to ensure that water will flow over or along, but not against exposed edges.
Starting at low point of roof, apply uniform and continuous mopping of the specified hot-melt adhesive using a standard roofing mop or Tremco approved felt layer.
Three ply membrane: Start and finish roof membrane along edges, terminations and projections, use starting/finishing strips; 12, 24, and 36” (305, 610, 914 mm) wide plies. Install THERMglass Type IV in shingle fashion.

Overlap starter strips 26” (660 mm) with first ply, then overlap each succeeding ply 24-2/3” (626 mm).
Four ply membrane: Start and finish roof membrane along edges, terminations and projections, use starting/finishing strips: 9, 18, 27, and 36” (229, 457, 685, 914 mm) wide plies.
Install THERMglass Type IV in shingle fashion. Overlap starter strips 29” (737 mm) with first ply, then overlap each succeeding ply 27-1/2” (699 mm).
Interply adhesive: Embed each ply in uniform and continuous mopping of specified hot-melt adhesive. Ply shall never touch ply. Apply specified hot-melt adhesive no more than 10’ (3 m) ahead of each roll. Lightly broom plies from unmopped side to ensure complete adhesion. Overlap previous work 24” (600 mm). Lap ply sheet ends 6” (150 mm). Extend all plies to top edges of all cants and cut excess evenly. Stagger end laps.
Avoid walking on plies until adhesive has cooled.
BUR systems: 25 lb/100 ft2 (1.2 kg/m2) ± 20% Install flashing as specified.
Gravel and smooth surfacing options are available. Consult your local Tremco Representative for specific surfacing options.
• Not intended to perform under ponding conditions. Positive drainage is required.
• Do not apply when ambient temperature prevents installation of hot-melt adhesives within stated application temperature range.
• Do not expose to solvents, oils, or other contaminants harmful to asphaltic materials.
Your local Tremco Roofing Sales Representative can provide you with effective maintenance procedures which may vary, depending upon specific conditions. Periodic inspections, early repairs and preventative maintenance are all part of a sound roof program.
