Rooftop amenity decks and paver systems turn otherwise unused roof areas into functional spaces for seating, walking, dining, recreation, equipment access, and other building uses. In Florida, however, these systems…

Laying out roof zone dimensions is an important step in designing, inspecting, repairing, or replacing a commercial roof. Roof zones help identify areas that experience different wind pressures and determine…

A blue roof is a roof designed to temporarily store and control rainwater rather than immediately draining all stormwater from the roof. Unlike a traditional roof, which is generally designed…

A Florida green roof can provide stormwater management, energy benefits, and additional usable landscape space, but its vegetation must be kept healthy through an appropriate irrigation strategy. Florida green roofs…

A protected membrane roof (PMR) assembly, also called an inverted roof, inverted roof membrane assembly (IRMA), or “upside-down roof,” is a low-slope roofing system in which the waterproofing membrane is…

Wind pressure zones are designated areas on a low-slope roof that experience different levels of wind uplift during severe weather. These zones are important when designing and installing commercial roofing…

A wind uplift calculation letter is a professional engineering document that confirms the wind pressures a roof system is designed to resist. It is commonly requested for commercial roofing projects,…

Building height is an important factor when engineers calculate roof uplift pressures caused by wind. As a building becomes taller, its roof can be exposed to stronger and more complex…

The ground elevation factor (Ke) is a wind-design factor used in ASCE 7 to account for changes in air density caused by a building’s elevation above sea level. It is…
