Interchangeable underlayer for a roofing device
View Patent ↗An interchangeable underlayer for a roofing device is provided. The interchangeable underlayer includes a base having a roof engaging first side and a roofing device engaging second side. The first side includes a plurality of protrusions and channels that engage with a surface of a roof. The second side includes a set of protrusions that secure to the roofing device, such as a roofing step that provides a non-sloped surface while working on a roof. In some embodiments, the roofing device includes a top side, a bottom side, and a pair of lateral sidewalls therebetween, wherein the bottom side can receive the set of protrusions of the second side of the base, forming the underlayer of the roofing device. The base is interchangeable with a second base having a differently configured first side to allow the roofing device to be used on a variety of different types of roofs.
1. An interchangeable underlayer for a roofing device, comprising:
a base having a first side and a second side, wherein the second side is configured to removably secure to the roofing device and the first side is configured to be placed directly on a roof;
wherein the first side comprises a plurality of projections and a channel formed between the plurality of projections;
wherein the second side comprises a first fastener configured to secure the base to a first mating fastener of the roofing device;
wherein the base is interchangeable with a second base, wherein the second base comprises a first side having a different configuration of projections.
2. The interchangeable underlayer of claim 1 , wherein the first fastener comprises a first set of protrusions and a second protrusion, wherein the first set of protrusions are disposed around a perimeter of the second side of the base and the second protrusion is elongated and centrally disposed on the second side of the base.
3. The interchangeable underlayer of claim 1 , wherein the second base comprises a foam material having a second side with a second fastener having a same configuration as the base and configured to secure the second base to the first mating fastener of the roofing device.
4. The interchangeable underlayer of claim 1 , further comprising a tie down extending from the channel, wherein the tie down is configured to secure to the roofing device.
5. The interchangeable underlayer of claim 1 , further comprising the roofing device having a top side, a bottom side, and a pair of lateral sidewalls therebetween, wherein the bottom side is configured to receive the fastener of the second side of the base, forming the underlayer of the roofing device.
6. The interchangeable underlayer of claim 5 , wherein the fastener comprises a first set of protrusions disposed around a perimeter of the first side of the underlayer.
7. The interchangeable underlayer of claim 6 , wherein the bottom side of the roofing device comprises a mating fastener having a first set of recesses configured to align with and receive the first set of protrusions.
8. The interchangeable underlayer of claim 5 , wherein the first fastener further comprises a second protrusion that is elongated and centrally disposed on the first side of the base.
9. The interchangeable underlayer of claim 8 , wherein the bottom side of the roofing device comprises a second recess configured to align with and receive the second protrusion.
10. The interchangeable underlayer of claim 5 , further comprising a tie down extending through the channel, wherein the tie down is configured to secure to the roofing device.
11. The interchangeable underlayer of claim 10 , wherein the roofing device comprises a receiving member disposed on each lateral sidewall for receiving the tie down therearound.
12. The interchangeable underlayer of claim 11 , wherein the receiving member is a knob.
13. The interchangeable underlayer of claim 5 , wherein the roofing device comprises a handle inset within each lateral sidewall.
14. The interchangeable underlayer of claim 5 , wherein the roofing device comprises a handle extending outward from a lateral sidewall of the pair of lateral sidewalls.
15. The interchangeable underlayer of claim 5 , wherein the roofing device comprises a front side and a rear side extending between the pair of lateral sidewalls, wherein the front side comprises a plurality of ridges.
16. The interchangeable underlayer of claim 1 , further comprising a magnetic fastener secured to the base.
17. The interchangeable underlayer of claim 1 , wherein the base is injection molded.
