Self-adhered roofing systems and methods
Some embodiments of the present disclosure relate to roofing systems. In some embodiments, the roofing system includes a deck, a roofing material, and an underlayment configured to be positioned between the roofing material and the deck. In some embodiments, the underlayment comprises a foil layer and an adhesive layer that is attached to the foil layer and attachable to the deck. Methods of manufacturing roofing systems are also disclosed.
1. A roofing system comprising:
a deck;
a roofing material; and
an underlayment between the roofing material and the deck, wherein the underlayment comprises
a non-woven surface layer,
a first polymer layer,
a reinforcement layer,
a second polymer layer,
a foil layer,
a first adhesive layer, and
a second adhesive layer,
wherein the first adhesive layer comprises an asphaltic adhesive or butyl adhesive,
wherein a top surface of the first adhesive layer contacts the foil layer,
wherein a bottom surface of the first adhesive layer contacts the deck,
wherein a bottom surface of the second adhesive layer contacts the foil layer,
wherein the first polymer layer is disposed above the second adhesive layer,
wherein the non-woven surface layer is disposed above the first polymer layer,
wherein the reinforcement layer contacts the first polymer layer and the second polymer layer,
wherein the non-woven surface layer contacts the second polymer layer, and
wherein the roofing material contacts a top surface of the non-woven surface layer.
2. The roofing system of claim 1 , wherein the first adhesive layer comprises a thickness of 4 mils and 100 mils.
3. The roofing system of claim 1 , wherein the first adhesive layer is a self-adhering adhesive.
4. The roofing system of claim 1 , wherein the roofing material comprises a shingle, a waterproofing membrane, or a tile.
5. The roofing system of claim 1 , wherein the non-woven surface layer is resistant to ultraviolet light.
6. The roofing system of claim 1 , wherein the non-woven surface layer is reflective of infrared light.
7. The roofing system of claim 1 , wherein the non-woven surface layer comprises polymer fibers, natural fibers, glass fibers, or any combination thereof.
8. The roofing system of claim 1 , wherein the foil layer comprises aluminum.
9. The roofing system of claim 1 , wherein the foil layer comprises a thickness of 1 μm to 100 μm.
10. The roofing system of claim 1 , wherein the foil layer is a fire barrier.
11. The roofing system of claim 1 , wherein the second adhesive layer contacts the first polymer layer.
