Expert Verdict — Reviewed by the SuperArbor Pro Desk
Pick the 18-inch width where you need to extend protection well beyond an opening onto the field of the wall; keep 12-inch rolls for sill pans, jambs, and headers. Lapse the wrap so water runs onto, not under, the lower course, and coordinate it with your flashing sequence before siding goes up. Always verify fastening and seaming requirements with the manufacturer's current installation instructions for your climate zone.
Modified bitumen rolls are heavy and work best on dry, moderate-temperature days; follow the manufacturer's installation guidance and keep the work area clear of slip and fall hazards when handling rolls at height.
Order Tamko Moisture Wrap in the 12 in. or 18 in. x 75 ft. roll that fits your opening schedule.
