Ludowici Interlocking Tile Installation Manual: Lexington Slate & Century Shake <br />70 www.ludowici.com <br /> Snow Guards <br />Snow guards are generally required in areas where snow <br />and ice may accumulate on the roof. Snow guards are <br />sometimes used on sloped roofs to prevent a mass of snow <br />or ice from sliding off the roofs and injuring persons, <br />damaging gutters or plants and blocking walks and <br />driveways. Snow guards hold the snow in place above the <br />eaves until it can melt and the water runs off. <br />It is recommended that snow guards should be installed <br />on at least 3 or 4 courses, offset from course to course, <br />spaced in staggered interval rows. Begin with the third <br />or fourth row. However, spacing and quantity of snow <br />guards is a matter of judgement based on local weather <br />conditions (see Figure 75.1). <br />Alpine conditions will require a professional engineer to <br />design the required snow retainage system. Tile should <br />not be exposed to ice and snow loads exceeding 100 <br />pounds per square foot. <br />A snow guard must be made of nonferrous material to <br />prevent possible rust stains. <br />Figure 70.1 Snow Guard Spacing <br />Repair <br />To replace a broken or damaged tile do not use an <br />exposed Copper strap. These are unsightly and can <br />work loose allowing the replacement tile to slide out. <br />Completely remove damaged <br />tile and fasteners. A slate <br />ripper will facilitate removal <br />of fasteners. Measure the <br />distance from the top of the <br />course below to the bottom <br />of the adjacent tile to the <br />replacement. <br />Align a Quik-Tach™ <br />Bracket on the back of the <br />replacement tile to the <br />correct bracket spacing. <br />Wire bracket to the <br />replacement tile with 16 ga. <br />Copper Wire. <br />Lift the tile in the course above <br />and slide the replacement <br />tile into place so the bracket <br />engages the top of the tile <br />below the replacement. <br />Apply a small bead of <br />Sealant or roofing Cement <br />under replacement tile. <br />Quik-Tach™ <br />Bracket Spacing <br />Replacement <br />Tile Small Bead of <br />Sealant <br />Figure 71.3 <br />Replacement Tile with <br />Quik-Tach™ Bracket <br />Figure 71.2 <br />Remove Damaged Tile <br />Figure 71.1 <br />Damaged Tile <br />Ludowici’s Quik-Tach™ Brackets are a quick, efficient <br />and concealed method for tile replacement.
