44 M AY / J U N E 2 0 1 8 in the Tile Replacement Mount saving time. Although, there are a number of variables that affect installation times, the Tile Replacement Mount will save on average a minute per mount." Quick Mount's Tile Replacement Mount comes with a 25-year warranty and features a universal base mount, which works with three f lashing profiles including a f lat tile, S-shaped tiles and W-shaped curved tiles. "Once you see more of these large-scale installs, it will drive the market for tile replacements," says Brandon Gwinner, the western region sales manager for SunModo. One of his customers using SunModo's tile replacement on a large cement tile project in Hawaii with 2,800 support points, reports cutting project labor costs in half — with no tile breakage. The SunModo tile replacement can be attached either by a single bolt into a rafter, like most tile replacement designs, or by four screws into the sheathing, in cases where a rafter is not reach- able. The industry is now trending toward the sheathing-attached method since it is more reliable and is now proven, Gwinner notes. While his company specifies no less than 1/2-in. oriented strand board (OSB) sheathing, many home builders or roofers opting for cement tiles are upgrading the sheathing by using thicker OSB, if not structural-grade 5-ply plywood, he notes. Here Comes a Regular After the construction downturn resulting from the recession in 2008, roofing is on an upturn and expected to reach a global value of $95 billion by 2024, according to a September report by Global Industry Analysts. Cement tile is the fastest growing segment of the global roof ing market, with an estimated combined average growth rate of close to 7 percent by 2020, according to a recent study by Technavio. Recent hurricanes and other adverse weather have helped demonstrate the durability of cement tiles over asphalt shingles and over clay tiles, which are much lighter than cement tiles. In the U.S. South and Southwest, where daily temperature highs and lows range widely, and air conditioning is a major use of electricity, cement tiles are a favorite because they can be used for cool roofs as well as for evening heat retention. Tile replacements for cement tiles already are highly waterproof and manufactured with formable aluminum. But cement tiles also are evolving via nanotechnology. Nanotech coatings for cement tiles will provide additional benefits for protection against heat, mold, mildew, fungus and algae, according to Global Industry Analysts. Overall, signs indicate that the U.S. adoption rate for tile replacements should accelerate. However, at the heart of the market is installer awareness and preference. "For the market to grow, installers will need more education about the advantages of tile replacements," suggests Stella Sun, the marketing director for SunModo. Charles Thurston is a freelance writer covering solar energy from Northern California. He is not to blame for all of the Replacements song references. SnapNrack's tile replacements feature a base assembly for simply lagging the base into place and then sliding the riser shaft into position for the tile replacement flashing.
