Protecting the Slab from Above
The International Roofing Expo (IRE) 2026 is taking place January 20-22 in Las Vegas. While roofing might seem distant from floor testing, the two are intrinsically linked through the building envelope’s integrity. Water infiltration from a compromised roof during construction can saturate concrete slabs, leading to months of delays in drying.
Temporary Roofs and Slab Drying
One critical topic for General Contractors is the timing of the “dried-in” status. IRE 2026 will showcase temporary waterproofing solutions that allow interior work, including slab analysis, to proceed earlier in the schedule. However, if these temporary measures fail, the slab acts as a sponge. We advise all clients to verify the roof’s integrity before scheduling sensitive moisture testing.
Vapor Barriers vs. Roof Membranes
Interestingly, the technology behind underslab vapor retarders and roof membranes is converging. Understanding the permeance ratings discussed at IRE can help specifiers choose better protection for the entire building shell.
