IIBEC Technical Advisory No. 018-2019 (updated 2021) Electronic Leak Detection

June 08, 2021

With the desire to improve the service life of roofing and waterproofing systems, a need has arisen to improve both quality control (QC) and trouble-shooting techniques of these systems. The introduction of nondestructive electronic leak detection (ELD) testing has provided additional options to meet this demand. Since QC is an increasingly important aspect in today’s construction projects, ELD is becoming a commonly specified and utilized procedure to determine watertightness in roofing and waterproofing assemblies...

IIBEC Technical Advisory No. 020-2021: Roof Covering Systems and New Concrete Roof Decks

January 14, 2021

Roof membrane and roof assembly installations over new concrete roof decks have always been prone to moisture-related problems due to latent moisture release by the concrete as it continues to cure. The problems are due to the release of excess moisture from the concrete into the roof assembly, which can impact roof system securement, the roof membrane, roof insulation, and related components. Moisture-related problems for roof membrane and roof assembly installations over concrete decks have increased significantly in recent years with changes in roofing materials, adhesives, construction practices, and schedules.

IIBEC Technical Advisory No. 016-2018: Reuse of Roof Insulation

September 01, 2018

Billions of square feet of roofing are replaced or repaired every year, and the existing roof insulation is typically removed and disposed into landfills. However, when roofs are recovered or repaired, the existing insulation is typically left in place rather than removed. Roofs are generally replaced when reaching the end of the useful service life or experiencing widespread/uncontrolled water entry. Owners, designers, and contractors may consider reusing the existing roof insulation when replacement of the roof system is performed. As such, IIBEC recommends members review the following when considering reuse of existing roof insulation on roof replacement projects.
