Exposure C: Open terrain with scattered obstructions having heights generally less than 30ft (9.1m). This category includes flat open country, grasslands, and all water surfaces in hurricane prone regions. Exposure C applies for all cases where Exposure B or D does not apply.
Exposure B: Urban and suburban areas, wooded areas, or other terrain with numerous closely spaced obstructions having the size of single-family dwellings or larger. Exposure B shall apply where the ground surface roughness condition prevails in the upwind direction for a distance of at least 2,600ft (792 m) or 20 times the height of the building, whichever is greater.
Exposure D: Flat, unobstructed areas and water surfaces outside hurricane prone regions. This category includes smooth mud flats, salt flats, and unbroken ice. Exposure D shall apply where the ground surface roughness prevails in the upwind direction for a distance greater than 5,000ft (1,524m) or 20 times the building height, whichever is greater.
The Occupancy categories range from I to IV, where Occupancy Category I represents buildings and other structures with a low hazard to human life in the event of failure and Occupancy Category IV represents essential facilities.
Buildings and other structures that represent a low hazard to human life in the event of failure, including, but not limited to:
All buildings and other structures except those listed in Occupancy Categories I, III and IV

Built-Up Roofs: Built-Up Roofsystems are commonly referred to as “tar and gravel” roofs. It is composed of alternating layers of bitumen and reinforcing fabrics that create a finished membrane. The bitumen typically used in Built-Up Roof systems is asphalt, coal tar or cold-applied adhesive. The surface may be smooth, capped with mineral surfaced cap sheet or gravel.
Modified Bitumen: Modified Bitumen are composite sheets consisting of copolymer modified bitumen often reinforced and sometimes surfaced with various types of films, foils and mats. Common types are APP and SBS.
Single-Ply: Single-Ply is a layer of flexible membrane that can be applied as fully adhered, mechanically attached or ballasted.
Other Roof Membrane:
Fully Adhered: A fully adhered membrane is attached to the roof by application of liquid-applied contact adhesive. Seams are sealed by membrane suitable method.
Mechanically Attached: A mechanically attached membrane is applied loose and is attached to the roof using fasteners. Seams are sealed by membrane suitable methods.
Ballasted: A ballasted membrane is applied loose without adhesives or mechanical fastening. Stones or paver ballasts are placed on top of the roof membrane.
