Construction site safety is an aspect of construction-related activities concerned with protecting construction site workers and others from death, injury, disease or other health-related risks.

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.

Ponding is the (typically) unwanted pooling of water, typically on a flat roof or roadway. Ponding water accelerates the deterioration of many materials, including seam adhesives in single-ply roof systems, steel equipment supports, and particularly roofing asphalt. On low-slope asphalt roofs, ponding water allows the oil solvent components of the asphalt to leach out and evaporate, leaving the roof membrane brittle and susceptible to cracking and leaking in the ponding location. The time taken for water to saturate a zone, usually from rainfall, causing a pond to form, is referred to as the "ponding time" or "time of ponding".

A roof seamer is a portable roll forming machine that is used to install mechanically seamed structural standing-seam metal roof panels, as part of an overall metal construction building envelope system. The machine is small and portable to be handled by an operator on top of a roof. The machine is applied to the overlapping area when two parallel roof panels meet. The action of the machine bends the two panels together to form a joint that has weather-tight qualities superior to other types of roof systems and cladding.
