The roof covering is the exterior part of the roof and does not contribute to the building's stability. It is designed to endure all weather conditions such as rain, snow, hail, and wind, as well as external environmental factors like marine environments and the weight of maintenance personnel.
For low-slope roof applications, a roof product qualifying for the Energy Star label under its Roof Products Program must have an initial solar reflectivity of at least 0.65, and weathered reflectance of at least 0.50, in accordance with EPA testing procedures. [53]
ICF decking can also be designed in conjunction with ICF walls to form a continuous monolithic structure joined together by rebar. ICF deck roofs are popular in storm-areas, [14] but it is harder to build complex roof shapes and concrete can be poured only up to a point on angled surfaces, often 7:12 maximum pitch. [15]
Flat roofs, or "low-slope" roofs, are also commonly found on commercial buildings throughout the world. The U.S.-based National Roofing Contractors Association defines a low-slope roof as having a slope of 3 in 12 (1:4) or less. [2] Flat roofs exist all over the world, and each area has its own tradition or preference for materials used.
A hot roof is a roof designed not to have any ventilation and has enough air-impermeable insulation in contact with the sheathing to prevent condensation [11] such as when spray foam insulation is applied directly to the under-side or top-side of the roof deck or in some cathedral ceilings. [12]
Steel panels are popular roof coverings in some areas, preferred for their durability. Slate or tile roofs offer more historic coverings for light-frame roofs. Light-frame methods allow easy construction of unique roof designs; hip roofs, for example, slope toward walls on all sides and are joined at hip rafters that span from corners to a ridge.
