Patent number: 11813703Abstract: Disclosed is an additive manufacturing process for making shingles and roof tiles. The entire shingle, including the substrate, can be manufactured on location, or a substrate can be manufactured at a manufacturing plant and then colored and textured on location to provide a wide variety of shapes and colors of shingles and roof tiles. Costs for inventory and shipping are reduced and a greater variety of shapes and colors can be provided for the shingles and roof tiles. The additive manufacturing equipment can be mounted on a truck so that the additive manufacturing techniques can be a mobile application of the additive manufacturing technology.Type: GrantFiled: May 20, 2020Date of Patent: November 14, 2023Assignee: TAMKO Building Products LLCInventors: David C. Humphreys, Chris Freeborg

Patent number: 11186747Abstract: An asphalt shingle coating system that includes a coater, a mixer, a viscosity gauge, a wax supply, a wax pump and a control system. The coater applies a layer of a coating asphalt mixture on an asphalt shingle substrate. The mixer mixes the coating asphalt mixture and is positioned upstream of the coater. The viscosity gauge may be positioned between the coater and the mixer, and it measures the viscosity of said coating asphalt mixture before it is delivered to the coater. The wax supply is in fluid communication with the mixer and a wax pump may deliver a volume of wax from the wax supply to the mixer, and the control system may selectively adjust the operation of the wax pump to substantially maintain a desired viscosity of said coating asphalt mixture.Type: GrantFiled: October 11, 2019Date of Patent: November 30, 2021Assignee: TAMKO Building Products LLCInventor: David C. Humphreys

Patent number: 10857759Abstract: Disclosed is waterproofing sheeting that uses a polyester layer that provides high lateral stability and puncture resistance. The waterproof sheeting can be used in many applications including waterproof roof underlayments waterproof sheeting for foundations, underlayment for tile and flooring and various other applications. The waterproof sheeting can be manufactured without many of the problems associated with the granular coatings of existing waterproof sheeting that create excessive wear and environmental hazards.Type: GrantFiled: June 14, 2018Date of Patent: December 8, 2020Assignee: TAMKO Building Products, LLCInventors: David C.

Patent number: 10415248Abstract: A roofing shingle comprising a base mat having a tab portion covered with granules and a headlap portion covered with a mask or film layer. An asphalt-based coating is applied to at least a top surface of the base mat. The film layer is adhered to the asphalt-based coating applied to the headlap portion and the granules are adhered to the asphalt-based coating applied to the tab portion. The film layer is adapted for preventing granules from adhering to the headlap portion of the base mat and, as such, the headlap portion may be substantially free from any granules adhered thereto. A method for manufacturing a roofing shingle is also provided wherein granules that are not adhered to the tab portion of one shingle may be collected and reapplied the tab portion of another shingle.Type: GrantFiled: March 11, 2014Date of Patent: September 17, 2019Assignee: TAMKO Building Products LLCInventors: David C.

Publication number: 20150126088Abstract: A roofing underlayment comprising a carrier substrate included a felt mixture and a binder mixture, and a volume of asphalt flux saturating the carrier substrate. The felt mixture may comprise between about seventy-five percent and about ninety-five percent by weight corrugated paper/cardboard fibers and between about five percent and about twenty-five percent by weight fiberglass fibers. The volume of asphalt flux may comprise between about twenty-five and fifty percent of a total weight of the roofing shingle underlayment and may saturate the carrier substrate at a saturation percentage between about thirty and about one hundred percent. The binder mixture may include a mixture of alum and rosin having a mixture ratio by weight of alum to rosin in a range between one to one (1:1) and four to one (4:1).Type: ApplicationFiled: October 31, 2014Publication date: May 7, 2015Inventors: Michael R.
