DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to FIG.
1, a peaked sloping roof 11 with rafters 13 utilizing the invention is shown.
A series of base members 15 are mounted on the rafters 13.
A riser 17 is used to elevate the base member 15 of the first tier 19.
The base members 15 may be made from a wide variety of materials including solid wood, plywood strips or even fiberglass.
Starting with the base member 15 of the first tier 19, the base members 15 are mounted, as previously stated on the rafters 13, but with the lower edge 21 of the first base member 15 elevated off the rafters 13 by the riser 17.
The riser 17 is secured rigidly to the rafters 13 by nailing or other equivalent fasteners.
The riser 17 is secured to the rafters 13 at the lowest point or the bottom edge 23 of the rafters 13.
The base member 15 of the first tier 19 extends from the riser 17 back to the rafters 13 and both the riser 17 and the base member 15 are secured to the rafters 13 by any suitable means such as nailing.
The riser 17 causes the base member 15 of the first tier 19 to be located at an acute angle with the horizontal less than the acute angle to the horizontal of the rafters 13 which is substantially the same angle of all the base members 15
