Bridging (Roofing)

What Does Bridging Mean in Roofing? Bridging is typically seen at roof-to-wall transitions on low-slope membrane roofs, where the roofing material changes direction from horizontal to vertical. Instead of following the shape of the surface below it, the membrane...
Ponding

Ponding

What Causes Ponding Water on Low-Slope Roofs Ponding water most commonly appears on flat or low-slope commercial roofs after heavy rainfall. Because these roofs are designed with minimal pitch, water can collect in low areas if slope is insufficient or water’s path to...

R-Value (Roofing)

Why R-Value Matters in Roofing R-value is most often referenced when discussing insulation in a roof systemRoof Types - A roof system (roof assembly) is the entire series of roofing layers and components above the roof deck that work together to weatherproof the...
Structural Slope

Structural Slope

Why Structural Slope Matters on Low-Slope Roofs Structural slope is often discussed during roof inspections, drainage diagnostics, or replacement planning. Low-slope roofs are not flat; they are designed with a minimum pitch of ¼ inch per foot to move water off the...
Thermal Bridging (Roofing)

Thermal Bridging (Roofing)

What Is Thermal Bridging in Roofing? Thermal bridging is typically discussed with metal fasteners, roof curbs and other components that allow heat to bypass part of the insulated roof assembly. Heat naturally follows paths with less resistance, like water finding the...
