A multi-layered shingle includes an underlay sheet having a longitudinally extending axis and a leading edge. The underlay sheet further defines a first layer and a second layer. The second layer is connected to the first layer along a first longitudinally extending fold line and folded against the first layer. An overlay sheet is bonded to the underlay sheet, and the first and second layers of the underlay sheet define multiple layers of a multi-layered shingle.

A ventilation system for ventilating of an attic is provided. The ventilation system includes an intake vent, a first member and a ventilation fan. The ventilation fan is configured to draw a flow of air from areas external to the building, through the intake vent and through the first member. A manifold adapter is connected to the ventilation fan and configured to receive a flow of air from the ventilation fan. A plurality of manifolds is connected to the manifold adapter. Each manifold has a plurality of apertures and is configured to receive flows of air from the manifold adapter and channel the flows of air through the apertures. A plurality of exhaust vents is in fluid communication with the flows of air from the apertures. The ventilation system is configured to allow flows of air exiting the apertures to circulate within the attic and exit through the exhaust vents.

A shingle blank includes a substrate coated with asphalt. A substantially V-shaped perforated cut line is formed in the substrate, and a substantially straight cut line extends from an apex the V-shaped perforated line toward a leading edge of the shingle blank. The V-shaped perforated cut line and the substantially straight cut line are structured and configured to facilitate separation of the shingle blank into discrete portions.

Shingle blanks are provided. The shingle blanks include an underlay portion having a substrate coated with an asphalt coating and granules, the underlay portion having an upper edge and a lower edge. An overlay portion is adhered to the underlay portion, the overlay portion having a plurality of continuous layered segments, the layered segments having a sealant bead therebetween. A plurality of perforation lines extend in a substantially perpendicular direction from the upper edge to the lower edge of the underlay portion. The plurality of perforation lines are sufficient to facilitate separation of the shingle blank to form hip and ridge roofing shingles configured for application across a ridge or hip.

Shingle blanks including a first fold region, a second fold region, a third region, a lower edge and an upper edge are provided. The shingle blank has a length. The first and second fold regions extend substantially across the length of the shingle blank. The second fold region is positioned between the first and third fold regions. A first perforation line is positioned between the second and third fold regions. A second perforation line is positioned between the first and second fold regions. A reinforcement material is positioned over the first perforation line and configured to reinforce the first perforation line. The reinforcement material includes apertures configured to allow an asphalt coating to bleed through the reinforcement material. The first and second perforation lines facilitate folding of the first and second fold regions on top of the third region to form a three layered stack.

An apparatus and method for monitoring the status of a steam trap include a device for sensing a process condition of the steam trap and a device for processing the sensed condition. The apparatus can include a processor positioned on a steam trap. The connection of the monitoring device to the steam trap can be to the trap itself or to an adjacent pipe or other apparatus.

An apparatus for dispensing granules onto a moving asphalt coated sheet includes first and second granule feed chambers containing granules that are fed to a discharge slot by first and second pockets. The pockets are formed in a slidable divider positioned between the feed chambers and the discharge slot. The divider is slid between a first position and a second position by a fluid powered actuator via an actuator rod. In the first position, the first pocket is in communication with the first granule feed chamber to receive granules from the feed chamber and the second pocket is in communication with the discharge slot for discharging the granules contained in the second pocket. In the second position the first pocket is in communication with the discharge slot for discharging the granules contained in the first pocket and the second pocket is in communication with the second feed chamber to receive granules from the feed chamber.
