Roof tile construction using sandwiched adhesive
First Claim
1. A method for applying roof tiles with one-component, polyurethane adhesive to a roof, each roof tile having opposing leading and trailing edge portions intersecting with opposing side marginal edge portions, an underside surface adapted to face the roof and an outside surface adapted to face the elements when the roof tile is installed on the roof, said method comprising the acts of:
- a) dispensing for each tile, the adhesive as a bead in a contiguous integral U-shaped, bead pattern having top and bottom adhesive leg deposits extending from the leading edge portion a distance towards the trailing edge portion adjacent the upper and underside surfaces, respectively, of the tile and a bight bead adhesive deposit adjacent to and extending away from the leading edge portion, but integral with and connecting the top and bottom leg bead deposits;
b) positioning an upper tile to partially overlie an immediately adjacent lower tile in that the upper tile'"'"'s leading edge portion is adjacent the roof while the upper tile'"'"'s trailing edge portion extends past the leading edge portion of an immediately adjacent lower tile so that the U-shaped bead pattern of the lower tile is sandwiched between roof tiles and roof by i) its bottom bead deposit in contact with the roof and the underside of the lower tile;
ii) its top bead deposit in contact with the outside surface of the lower tile and the underside surface of the upper tile and iii) its bight bead deposit in contact with the roof, the underside surface of the upper tile and the leading edge portion of the lower tile; and
pressing the upper tile against the roof and lower tile to cause the adhesive in the U-shaped sandwiched bead pattern to spread out into additional sealing contact areas while the tile is vertically aligned with an adjacent tile at a desired spaced distance from the roof;
c) laying tiles side by side while repeating acts (a) and (b) for each placed tile to form a longitudinally extending tile course, each course, with the exception of the lowest first course, overlying a lower course, and each course, with the exception of the last, highest course, being overlaid by a higher course whereby, with the exception of the first and last courses, the tiles are secured to the roof by placing a single U-shaped bead pattern on each tile which becomes sandwiched into sealing contact with the roof and adjacent tiles as the tiles are laid into position; and
, d) thereafter, bonding the tiles to the roof after the polyurethane adhesive has cured.

Abstract
A roof construction uses a one-component adhesive to adhere roof tiles to a roof. The adhesive is formed in a U-shaped pattern in that the adhesive is dispensed in a bottom leg deposit on the tile'"'"'s underside, a bight deposit extending about the tile'"'"'s leading edge and a top adhesive deposit overlying the bottom deposit and extending on the outside surface of the tile. As the tiles are laid onto the roof in an overlying fashion, the U-shaped adhesive is sandwiched between the tile, the overlying tile and the roof forming sealing contact therewith and therebetween.

30. A method for installing roof tiles onto a roof comprising the acts of:
-
providing a supply of one-component adhesive foam;
providing a supply of roof tiles for attachment to said roof, each of the roof tiles having opposing leading and trailing edge portions interconnected by side edge portions, each of said roof tiles having an undersurface which opposes said roof when installed thereon and an outside surface substantially exposed to the elements;
choosing a set of first roof tiles from said roof tile supply;
dispensing at least a first bead deposit of adhesive foam spaced from but adjacent to the trailing edge portion of each first tile and a second bead deposit in the form of a U-shaped bead pattern of adhesive foam extending around the leading edge portion of each first tile;
placing said first roof tiles onto said roof in a course so that said trailing edge portions of said first roof tiles are positioned closer to an eave of said roof than said first roof tiles leading edge portions and laying said first roof tiles onto said roof so that contact is effected between said first bead deposit, said roof and said underside of the first tiles and between said roof and the adhesive in a bottom leg bead portion of the U-shaped bead pattern and the underside of the first roof tiles and between said adhesive in a bight bead portion of the U-shaped bead pattern and said roof;
choosing a set of second roof tiles from said roof tile supply;
dispensing the U-shaped bead pattern of said adhesive foam from said adhesive foam supply about the leading edge portion of said second tiles;
placing said second roof tiles onto said roof either before or after the U-shaped bead pattern has been formed so that said trailing edge portions of said second roof tiles are positioned over said leading edge portions of said first roof tiles and said leading edge portions of said second roof tiles are positioned over said roof and laying said second roof tiles onto said roof and said first roof tiles after the U-shaped bead pattern has been formed so that contact is effected a) between the roof and the underside of the second tiles and the adhesive in said bottom leg bead portion of said second roof tiles'"'"' U-shaped bead pattern and b) between the underside of said second roof tiles, said outside of said first roof tiles and the adhesive in said top leg portion of said first tiles'"'"' U-shaped bead pattern and c) between the underside of said second tile, the roof and the adhesive in the bight portion of the first tiles'"'"' U-shaped bead pattern;
choosing a set of subsequent roof tiles from said roof tile supply;
dispensing said adhesive foam in the U-shaped bead pattern about the leading edge portion of said subsequent tiles;
placing said subsequent roof tiles onto said roof so that leading edge portions of said subsequent roof tiles are positioned over said roof and trailing edges of said subsequent roof tiles are positioned over a preceding set of roof tiles, and laying said subsequent tiles onto said roof so that contact is effected a) between said roof and said underside of said subsequent tiles and the adhesive in said bottom leg bead portion of said subsequent tiles'"'"' U-shaped bead pattern and b) between said underside of said subsequent roof tiles, said outside of said tiles being overlapped and the adhesive in said top leg bead portion of said U-shaped bead pattern of the tiles being overlapped by said subsequent tiles and c) between the underside of said subsequent tiles, said roof and the adhesive in said bight bead portion of the tiles being overlapped by said subsequent tiles; and

-
dispensing a one-component, polyurethane froth in a U-shaped bead pattern extending from the underside of any given tile, around the leading edge portion of the given tile to the outside of the given tile, and placing the tile in overlapping relationship to a lower tile whereby the adhesive on the underside of the given tile contacts the roof adjacent the leading edge portion of the given tile while the underside of the given tile adjacent the trailing edge portion contacts the adhesive pattern dispensed on the lower tile to establish sealing contact between the underside of the given tile adjacent its trailing edge portion with the outside of the lower tile and between the underside of the given tile adjacent its leading edge portion with the roof. - View Dependent Claims (36, 37, 38, 39, 40)
