Inland Coatings introduced RC-2500 medium-grade fiber-reinforced SEBS mastic, which can be trowel or brush applied to roofing seams, flashings, and penetrations where thicker build is required.

This article is the author's second in a series on waterproofing penetrations.  Waterproofing Penetrations 102 takes a deep dive into unique penetrations and often challenging conditions. The types of assemblies that will be explored include cluster penetrations, fireproofed penetrations, and extreme temperature pipes (hot or sub-freezing).

Seven points that, if kept in mind during the design process, can eliminate many roofing-related change orders and reduce installation time and costs.

If a penetration is coordinated, detailed, and installed properly, it will achieve its desired result without creating unintended performance issues.

Flashing or stripping ply should extend into scupper throat, and be fully welded. Seal exterior of scupper at wall penetration. Continuous cleats are recommended when flashing face dimension exceeds 3 inches and in areas deemed a high-wind zone as categorized by local building code.

Roof leaks are often a nuisance for a building owner or property manager. Often difficult to track down, leaks can cause damage to interior finishes and lead to tenant complaints – and, if not resolved, unhappy tenants.

The most critical application points on low-slope roof systems are at flashings, penetrations and accessories.
