Have you ever wondered what types of questions people “Ask a TRI Expert?” This series, brought to you by the Tile Roofing Institute, allows 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 President and Technical Director, Rick Olson.

 

Question:

“Are tiles on a 5/12″ slope required to be nailed? If not, what are the requirements?”

Response:

“The answer is found on Table 1B, page 11 of the manual. Assuming the roof is in a moderate climate (not high-wind), and the tiles are installed with battens, fasteners are not required for field tile. Table 1B states: ‘Number of fasteners…with battens: for 5 units vertical in 12 units horizontal and below (42% slope), fasteners not required…All perimeter tiles require one fastener (fn5)*.’

*Footnote #5: Perimeter fastening areas include three tile courses but not less than 36 inches from either side of hips or ridges and edges of eaves and gable rakes.”

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!
