Have you ever wondered what types of questions people “Ask a TRI Expert?” This series, brought to you by the Tile Roofing Instituteallows anyone to ask anything about tile roofing installation, maintenance, etc. The Tile Roofing Institute (TRI) is a non-profit association of producers and associates of concrete and clay tile and is considered one of the leading experts in the industry. Here’s a recent question from a roofer repairing a concrete tile roof, and the response from TRI National Training Manager, John Jensen.


“When repairing older tile roofs, sometimes there is mortar around the pipes. Can we repair the mortar or are we required to install a metal secondary flashing?”


“Page 18 of the Concrete and Clay Roof Tile Installation Guide has a drawing of the requirements for pipe penetrations, as shown. Although it was common for roofers to pack mortar around the pipe, mortar is not a flashing. We are required to have two flashings at each pipe penetration; one integrated into the underlayment, and one installed with the tile. The drawings on Page 18 are very clear and Footnote #2 (below the drawings) states: All penetrations require a deck flashing and a tile flashing.”

If you have any questions regarding concrete tile or installation, the Tile Roofing Institute’s website, www.tileroofing.org, is a great resource. TRI also offers installation certification courses throughout the United States, so be sure to check their course schedule to register for one in your area!
