What is through-wall flashing, and why is it important for Iowa buildings?

Through-wall flashing is a waterproof barrier installed within masonry walls to redirect moisture out and away from the building. In Iowa, where buildings are frequently exposed to rain, snow, and freeze-thaw cycles, flashing helps prevent water damage, structural deterioration, and mold growth within walls.

Is through-wall flashing required by building codes in Iowa?

Yes. Most commercial and multi-family residential structures in Iowa are required to have proper moisture control systems, including flashing. Compliance with local codes in cities like Des Moines, Cedar Rapids, and Iowa City often requires professionally installed flashing to pass inspection.
