Roof Slope Fire Egress
This means for every 12 horizontal units the roof must rise a minimum of 3 vertical units.
Roof slope fire egress. For example a fire escape is defined as a means of egress because it s a way for someone to exit a building in an emergency. Lapped nonsoldered seam metal roofs without applied lap sealant must have a minimum roof slope of 3 12 25 slope. I interpret this to mean that if the door is locked on the stair side preventing free access to the roof it does not need to provide free egress from the roof. The occupant load number of dwelling units and common path of egress travel distance do not exceed the values in table 1006 3 2 1 or 1006 3 2 2.
The minimum roof slope for metal roof panels depend on 3 different scenarios. Low or no slope roofs up to a 10 degree pitch can be installed without the need for any additional anchoring other than what is found in a flat roof system. Most states and townships have building codes that require means of egress on each floor sometimes including finished basements and attics. A single exit or access to a single exit shall be permitted from any story or occupied roof where one of the following conditions exists.
Emergency exits on these floors usually come in the form of egress windows.
