A bi-functional roof drain includes a housing forming a drain manifold and a primary drain outlet to connect to a primary drainage system. A backup drain pipe penetrates the housing and extends through the manifold. The top of the backup drain pipe is positioned a distance above the housing, which may be variable. With this drain a method of retrofitting a roof drainage system to provide primary and backup water drainage is also presented. This method includes removing an existing uni-functional roof drain from a deck penetration through the roof, and installing a bi-functional roof drain in the same deck penetration. The two drain outlets are connected to the primary and backup drainage system. The height of a top opening of a backup drain pipe of the bi-functional roof drain may be adjustable in relation to a surface of the roof.

The clip of claim 3 wherein said fist and second flange-support legs are substantially equidistantly spaced from the opposite ends of said clip so that said two end sections which extend out from said bottom portion of said clip extend out from said first and second flange-support legs to said opposite ends of said clip and said first and second flange-support legs are centered on said clip. 5. The clip of claim 1, further including two end sections extending out from said opposite ends of said bottom portion, respectively, so that the overall length of said clip is equal to the length of said bottom portion and the length of said two end sections, said predetermined leg spacing being substantially less than said overall length of said clip. 6. A deck structure for attaching a deck board to a surface, comprising: a clip for attachment to said surface, said clip having a bottom portion which can be attached to said surface, said bottom portion having a length defined by a pair of opposite ends, said clip having a pair of flange-support legs extending up from a center section of said bottom portion, said flange-support legs being spaced in from said opposite ends of said bottom portion and being spaced apart from each other by a predetermined leg spacing; so that two end sections of said bottom portion of said clip extend out from said flange-support legs, respectively, to said opposite ends of said bottom portion, a pair of flanges, each flange being attached to and extending from at an upper end of a respective one of said pair of flange-support legs, so that each flange is spaced up by a predetermined flange height from said bottom portion, said flanges extending in opposite directions and away from each other and generally parallel to said bottom portion, an elongated deck board, said elongated deck board having a width substantially equal to the length of said clip, said deck board having an upper surface and an under side, said under side of said deck board having a bottom surface which is substantially parallel to said upper surface and an elongated recess in a portion of said bottom surface, said elongated recess extending along the length of said deck board, said elongated recess having a pair of sidewalls which directly face each other and which are spaced apart by a distance substantially the same as said predetermined leg spacing, said deck board having a pair of side portions on the respective sides of said portion of said bottom surface, said side portions having a width at least equal to that of said end sections of said bottom portion of said clip, the bottom portion of each of said pair of sidewalls of said elongated recess tapering up and inward toward the opposite sidewall to a ledge which faces upward, so that each of said sidewalls contains an upwardly facing ledge, one ledge extending from and being spaced up from the bottom of each sidewall by a distance substantially equal to said predetermined flange height, said ledges extending into said recess from said respecti
