Roofing system with changeable decorative elements
A roofing system comprises layered construction panels, each having a bottom structural layer to provide strength and support. A performance layer overlies the structural layer and provides performance or functional characteristics such as water proofing, water shedding and/or impact resistance. An upper or decorative layer overlies the performance layer and provides aesthetic features or a decorative appearance for the roofing system. The decorative layer of the construction panels can be removed without damaging or affecting the performance layer. The appearance of a roof can thereby be changed at will without requiring that the entire roofing system be removed and replaced.
1. A roofing system comprising:
a roof deck or substrate;
a plurality of roofing panels attached in series along the roof deck or substrate, each roofing panel having a selected decorative appearance and comprising:
a base layer including plywood, oriented strand board, structural insulated panels, metal, standing seam panels, cement, quartz, foam panels, polymers, or combinations thereof;
a performance layer overlying the base layer, the performance layer configured to provide one or more performance characteristics to the roofing system, including waterproofing, water shedding, impact resistance, wind resistance, fire resistance, microbial or algae resistance, and/or combinations thereof; and
a decorative layer overlying the performance layer, the decorative layer having at least one aesthetic characteristic selected and configured to provide the selected decorative appearance to the roofing panel;
wherein the decorative layer is selectively removable from the performance layer and replaceable with another decorative layer without substantially modifying the one or more functional characteristics of the performance layer so that the aesthetic characteristics imparted to the roofing panel by the decorative layer can be altered to alter or maintain the decorative appearance of the roofing panel without removal and/or replacement of the roofing panel or the performance layer or the base layer.
2. The roofing system of claim 1 wherein the aesthetic characteristics of the decorative layer comprise an appearance of shingles, shakes, slate, metal roofing, or tile roofing materials.
3. The roofing system of claim 1 wherein the decorative layer is releasibly attached to the performance layer with removable fasteners, debondable adhesives, or combinations thereof.
4. The roofing system of claim 1 wherein the aesthetic characteristics of the decorative layers of a plurality of the roofing panels installed together along the roof deck or substrate define an overall decorative appearance of a roof formed by the roofing system.
5. The roofing system of claim 1 wherein the performance layer comprises one or more of a thermoplastic polymer material, metal, composite materials, or combinations thereof.
6. The roofing system of claim 1 wherein the performance layer comprises polyethylene, polypropylene, acrylic, PET, polystyrene, polyvinyl chloride, polyisoprene, polyvinyl butyral, polycarbonates, multilayer thermoplastic constructions, or combinations thereof with and without fillers.
7. The roofing system of claim 1 , wherein the base layer is attached to the roof deck or substrate by bonding using sealant or adhesive materials, thermal bonding, hook and loop or similar connectors, fasteners, mechanical interlocking systems, or combinations thereof.
8. The roofing system of claim 1 , wherein the roofing panels of the plurality of roofing panels are positioned along the roof deck in a substantially abutting arrangement, and wherein adjacent panels are coupled together along joints defined therebetween by adhesives or thermal bonding.
