[0032] In some embodiments, the hooking feature 110 may further comprise a bracing portion 113 configured to facilitate a greater surface area of the hooking feature 110 and enhance surface grip. The hooking feature 110 may also comprise an enlarged looped profile, including but not limited to, a circle, teardrop, or polygonal shape. A padding feature may also be disposed upon the surface of the hooking feature 110, configured to enhance the surface grip of the hooking feature 110 while coupled to the surface of a roof 140.

[0033] In some embodiments, the scaffold member 100 may further comprise at least one wheel 170, shown in FIG. 5, coupled to a side of the stick member 160, configured to facilitate movement of the scaffold member 100 during assembly and adjustment of the system 10 while coupled to the surface of a roof 140. The at least one wheel 170 may be coupled to a side of the stick member such that the wheel 170 is in constant contact with the surface of the roof 140 while the system 10 is in use. The at least one wheel 170 may be coupled to a side such that contact between the wheel 170 and the surface of the roof 140 occurs only during assembly, adjustment, and disassembly of the system 10.

[0034] The at least one platform member 130, as shown in FIG. 6, comprise a top surface 131, bottom surface (not shown), and a plurality of sidewalls 132, configured to couple at least one platform support structure 120 attached to the scaffold member 100. The platform member 130 may also comprise a groove disposed upon the top surface 131 or bottom surface, configured to facilitate coupling of the platform member 130 to the platform support member 120. In some embodiments the top surface 131, bottom surface, and sidewalls 132 of the platform member 130 may comprise surface features configured to enhance surface grip between both the platform member 130 and the support member 120, as well as between the platform member 130 and a user. The surface features may include a rubberized coating or further configured with a pattern disposed therein and the pattern may include, but is not limited to, grooved or studded patterns.

[0035] In other embodiments of the invention, as shown in FIG. 7, the scaffold member 100 may comprise a plurality of step features 180 disposed at an interval along a side of the stick member 160, configured to allow a user to climb the scaffold member 100 in a ladder-like fashion. The plurality of step members 180 may be composed of materials similar to the rest of the system 10, and may be coupled to the scaffold member 100 by an attachment mechanism that is the same or similar to the attachment mechanism between the platform support structure 120 and scaffold member 100.

[0036] In some embodiments, the scaffold member 100 may also comprise at least one rail member 190 coupled to the plurality of step features 180, configured to stabilize a user while traversing the step features 180. The rail members 190 may comprise at least one support structure 191 coupled to the step features 180. The support structure 191 is coupled to and configured to support at least one guide rail 192, configured to be gripped by and guide a user during ascent or descent of the plurality of step features 180.

[0037] The method for using the adjustable roof scaffolding system 10 comprises coupling at least one platform support structure 120 to each of the plurality of scaffold members 100, at an initially suitable frequency along each scaffold member 100. The hooking feature 110 is then coupled to an end of each scaffold member 100. Each scaffold member of the plurality of scaffold members 100 with at least one attached platform support structure 120 and hooking feature 110 is then placed upon the surface of the roof 140. Each of the plurality of scaffold members 100 are then positioned such that the hooking feature 110 extends over a peak of the roof 150, abutting an adjacent slope of the roof 145, thereby securing each of the scaffold members 100 to the surface of the roof 140. At least one platform member 100 is then coupled to the corresponding platform support structure 120 of each scaffold member 100, thereby coupling each scaffold member 100 to another and completing the scaffold system 10. The coupling of a platform member 130 is then repeated until the system 10 comprises at least one platform member 130 configured in a pattern suitable for the purposes of the user, as shown in FIG. 8.

[0038] To adjust the scaffold system 10, the at least one platform member 130 is decoupled from the at least one platform support structure 120. The platform support structure or structures 120 are then decoupled from each scaffold member of the plurality of scaffold members 100. Each platform member of the plurality of scaffold members 100 are then decoupled from the surface of the roof 140 by raising the scaffold member 100 over the peak of the roof 150 until the hooking feature 110 is no longer abutting the opposite surface of the roof 145. The scaffold members 100 are each then placed in a new position along the surface of the roof 140, the hooking features 110 reengaged with the peak 150 and opposite surface of the roof 145. The at least one platform support structure or structures 120 are then recoupled to the scaffold member 100 in positions to suit the needs of the user. Each platform member 130 is then recoupled to the corresponding platform support structures 120 to relink the system 10 together. One of ordinary skill in the art would understand that not all the above described steps need be performed to adjust the system 10, and that the steps may be performed in such an order to provide sufficient customization of the system 10 to configure a coverage area suitable for the needs of the user.

[0039] Disassembly of the system 10 may be performed by first decoupling each platform member 130 from each of the platform support structures 120. At least one of the platform support structure 120 may then be decoupled from the plurality of scaffold members 100. Next, the plurality of scaffold members 100 may be decoupled from the surface of the roof 140 by raising the scaffold member 100 over the peak of the roof 150 until the hooking feature 110 is no longer abutting the opposite surface of the roof 145. The scaffold members 100 may then be rotated until the hooking feature 110 is disposed along a horizontal axis that is parallel to and clears of the peak of the roof 150. The scaffold members 100 are then further removed from the surface of the roof 140 by either utilizing the at least one wheel (not shown) disposed along a side of the scaffold member 100, or by sliding the scaffold member 100 off the surface of the roof 140. Once removed from the surface of the roof 140, the hooking feature 110 may be decoupled from the stick member 160 of the scaffold member 100.

[0040] A person of ordinary skill in the art will appreciate that the above described steps for disassembly of the system 10 may be performed in any order deemed necessary by the user for a given situation or project. The system 10 may be removed from the surface of the roof 140 as one piece and then dissembled, or each component disassembled and then removed from the surface of the roof 140.

[0041] Those of ordinary skill in the art will understand and appreciate the foregoing description of the invention has been made with reference to certain exemplary embodiments of the invention, which describe an adjustable roof scaffold system and method of use. Those of skill in the art will understand that obvious variations in construction, material, dimensions or properties may be made without departing from the scope of the invention which is intended to be limited only by the claims appended hereto.
