Ludowici Interlocking Tile Installation Manual: Morando 14" & 16" <br />34 www.ludowici.com <br />Morando 14" & 16" Tile Installation <br /> <br />NOTE: Each flat Interlocking field tile is provided with <br />two fastening nail holes and French field tile with one. <br />When installing field tiles or accessories care should be <br />taken to fasten each tile with nails or screws in every <br />provided fastening hole. <br />The following roof preparations must be completed <br />before installing any roof tile. <br />For detailed information on these items refer to the previ- <br />ous sections in this manual or the NRCA Manual on Steep <br />Roofing. <br />• Install the flashings required for ensuring <br />watertightness: <br /> – Eave Flashing <br /> – Rake Edge Flashing (if required) <br /> – Valley Flashing <br /> – Dormer and Sidewall Flashing, Skylight Flashing, <br />Chimney and Cricket Flashing <br /> – Vent Flashing <br />• Underlayment for the entire roof deck, including the <br />appropriate waterproof underlayments required for all <br />flashing and, where required, the ice dam membrane <br />• All cant strips and Hip and Ridge stringers should be <br />installed and covered in underlayment. <br />• Roof surface chalked with vertical and horizontal lines <br />• To avoid damaging the new roof adjoining walls, <br />chimneys and other above the roof line components <br />of the structure should be complete prior to installing <br />the tile to minimize other trades traversing the <br />completed roof. <br />Points to Remember During <br />Field Tile Installation <br />Tile installation will generally progress in a diagonal fashion, <br />moving from the starting point of the under eave tile. <br />• Use the chalk lines as a guide. <br />• Watch for any irregularities in the roof deck <br />construction. <br />• After the installation of about 75-100 tiles, the roof <br />should be inspected from the ground at a distance <br />greater than 40 feet to determine that there are no <br />streaks or blotches. To ensure a good range of tones, <br />this inspection must be done at regular intervals. <br />• When each course is 10 to 12 tiles from the terminating <br />end, compare the remaining distance to the width of <br />the tiles to determine if a slight crowding or stretching <br />of the tile may be required to ensure the last piece in <br />the course is an end band (1/2 tile) or a full tile. DO NOT <br />crowd or pull to the extreme any more than 5 or 6 <br />pieces positioned side by side. <br />V-Ridge <br />V-Closed Ridge End <br />FINISHER <br />Under Eave Tile <br />Right Detached Gable <br />Rake Tile <br />End Band Tile <br />V-Hip Starter <br />V-Hip <br />V-Ridge Terminal <br />2Hip/1 Ridge FINISHER <br />Figure 34.1 Interlocking Tile
