The asphalt shingle waste comprises 60 wt. % to 95 wt. % of limestone, granules, and/or impurities based on the total weight of the asphalt shingle waste. The method comprises obtaining a phase modifier. The method comprises mixing the virgin asphalt, the asphalt shingle waste, and the phase modifier to form an asphalt mixture. The phase modifier is present in an amount of 0.25 wt. % to 25 wt. % based on the total weight of the asphalt mixture. The asphalt mixture is configured to be applied to a roof substrate to obtain a roofing shingle.

Abstract: Systems and methods of applying self-seal strips of multiple different adhesives are disclosed. In one embodiment, two spaced apart spoked applicator wheel assemblies are positioned beneath a web of moving shingle stock such that each of the applicator wheels applies dots of different adhesives in an alternating pattern. In other embodiments, a layer of a second adhesive is deposited onto previously applied dots of a first adhesive to form layered adhesive dots with dual properties of both adhesives.

Abstract: Asphalt sealcoats and asphalt shingle waste coatings for roofing materials are provided. A roofing material comprises a substrate having an exposed surface and an unexposed surface. An asphalt shingle waste coating is located on at least a portion of the exposed surface of the substrate. The asphalt shingle waste coating comprises an asphalt shingle waste, wherein the asphalt shingle waste comprises a waste asphalt and a limestone. An asphalt sealcoat is located on at least a portion of the asphalt shingle waste coating. The asphalt sealcoat is substantially free of the asphalt shingle waste. The asphalt sealcoat has a thickness of no greater than 50% of a thickness of the asphalt shingle waste coating.

Abstract: A system for providing cryptographically-secured communication is disclosed. The system receives activities from clients including data for inclusion on a distributed ledger of a distributed ledger architecture. The system then processes each activity and determines whether an activity corresponds to an event subscribed to by at least one computing device. The event may correspond to the presence of a communication in an activity received by the system. The system validates the data associated with the activity by utilizing a plurality of validators and without requiring a threshold level of consensus if the activity corresponds to the event. If the activity does not correspond to the event, the system validates using the threshold level of consensus. Once the activity is validated, the system submits the data associated with the activity for inclusion on the distributed ledger so that the communication is made available to the at least one off-chain computing device.

Abstract: A roofing mock-up kit includes a container having at least two sides, at least one side is clear so as to visually display contents within the container, and at least three modular interchangeable roofing components, the at least three modular interchangeable roofing components configured to be assembled by a user, the modular interchangeable roofing components positionable in an assembled state within the container to form a scale replica of a roofing system, the modular interchangeable roofing components including at least one distinct interchangeable base layer, at least one distinct interchangeable insulation layer, and at least one distinct membrane layer.

Abstract: Silicone roofing materials are provided. A roofing material comprises at least one of a plurality of particles, a silicone coating, a substrate, an adhesive layer, a release liner, or any combination thereof. The substrate is located between the silicone coating and the adhesive layer. The adhesive layer is located between the substrate and the release liner. The release liner covers at least a portion of the adhesive layer. The plurality of particles covers at least a portion of a surface of the silicone coating. Each of the plurality of particles has a surface. When the roofing material is installed on a roofing substrate, at least a portion of the surface of the plurality of particles is exposed to an environment. Related systems and related methods are also provided.

Abstract: A method includes obtaining a spray device having a pump and a container containing an adhesive composition that does not include a propellant, operating the pump to pressurize the adhesive composition in the container to a pressure of 1 psi to 200 psi, spraying the adhesive composition from the container onto a roofing substrate to form an adhesive layer on the roofing substrate, and applying a roofing material to the adhesive layer on the roofing substrate.

Abstract: A roofing material is provided. The roofing material comprises a first layer, The first layer comprises 1% to 65% by weight of a first non-styrenic propylene copolymer based on a total weight of the first layer. The first layer comprises 1% to 65% by weight of a second non-styrenic propylene copolymer based on the total weight of the first layer. The first non-styrenic propylene copolymer is different from the second non-styrenic propylene copolymer. The roofing material does not comprise an olefin block copolymer. Other roofing materials, and related systems and related methods, are provided.

Abstract: Shingles have self-seal strips with features that include sealant dashes or dots separated by drainage gaps. The self-seal strips are registered with each shingle so that the features are positioned at the same locations on each shingle. A method of making such shingles includes synchronizing the rotation of sealant applicator wheels with the shingle chop cutter so that cuts are made at repeated designated locations along the applied self-seal strips.

Abstract: Some embodiments of the present disclosure relate to a method comprising mixing at least one compatibilizer precursor with at least one polymer, so as to result in a polymer concentrate and mixing the polymer concentrate with asphalt, so as to result in a polymer modified asphalt (“PMA”). Some embodiments of the present disclosure relate to formulations comprising a compatibilizer precursor, a polymer concentrate, PMA, or any combination thereof.

Abstract: Sprayable adhesive compositions are provided. A sprayable adhesive composition comprises at least one propellant, at least one solvent, and at least 50% by weight of solids based on a total weight of the solids and the at least one solvent. The solids comprise at least one polymer and at least one tackifier. Methods of installation, roofing systems, and various other related systems and related methods are provided.

Abstract: A solar module for a roof covering system that generates electrical power from sunlight includes a frame having a bottom surface supported on a deck of a roof, a top surface, and a thickness between the bottom surface and the top surface. The solar module also includes a solar element mounted to the top surface of the frame which has an upper surface. a micro-inverter mounted to the top surface of the frame and to the side of the solar element, and a raised access panel that is removably coupled to the frame to surround the micro-inverter. The raised access panel has an access panel top surface that is elevated above the upper surface of the solar element. The top surface of the frame forms a water shedding surface below the micro-inverter for directing water away from the roof.
