The invention relates to a method for determining a topology of a defined, bounded surface (1) for dewatering said surface by means of at least one specified dewatering point (21), so that the surface (1) comprises a monotonically increasing slope starting from the dewatering point (21) to a collision point (16), said method avoiding the disadvantages of eth prior art and determining in a more efficient, simple, and less error-prone manner a topology of a defined, bounded area (1) for dewatering the same by means of at least one specified dewatering point (21), so that the surface (1) comprises a monotonically increasing slope, starting from the dewatering point (21) to a collision point (16), and proposes that the topology is determined such that the surface (1) is subdivided into individual surface elements (2) each having at least one plane (3), wherein a slope in a first direction and/or a second direction perpendicular to the first direction is successively determined in every plane (3) for each area element (2), starting from the dewatering point (21).

A flashing overlay system for overlaying roofing materials occupying a roof valley includes multiple planar flashing units having at least one first non-planar feature, the flashing units arranged in pairs including a left flashing unit and a right flashing unit, the flashing unit pairs covering the roofing materials occupying the roof valley along the length and track of the roof valley, the paired flashing units abutted together along the edges of the planar material supporting the at least one first non-planar feature, the first non-planar features aligned generally with the center line of the roof valley. The units are tired together with at least one elongated saddle strip folded over at longitudinal center and clamped over, fastened over, or otherwise fitted over the abutted first non-planar features of the multiple planar flashing units paired together and overlaying the roofing materials occupying the roof valley.

The invention refers to a drainage system (100), in particular a roof drainage system, comprising an outlet member (10) and a flow restrictor (20), whereby the flow restrictor (20) is situated above the outlet member (10). The flow restrictor (20) comprises a contact portion (22) and the outlet member (10) comprises a flange portion (12), whereby a first sealing member (30) is arranged on and/or along the flange portion (12) of the outlet member (10) and a second sealing member (40) is arranged at the contact portion (22) of the flow restrictor (20).

The present disclosure provides a sump drain apparatus comprising a drain inlet and a ramp coupled to the drain inlet comprising an incline plane configured to divert drainage water toward the drain bowl, wherein at least a portion of the ramp is configured to be positioned on top of a roof deck.

A gutter uplift channel assembly is configured to mount skylights, smoke vents, or other roof accessories to a roof having a pair of longitudinally extending roof curbs. A gutter extends between the pair of roof curbs and is secured to the roof curbs to channel water laterally over the roof curbs. The gutter receives longitudinal ends of a pair of roof accessories to be mounted next to each other. An uplift channel or cap of the gutter channel assembly extends over the longitudinal ends or rims of the roof accessories and is secured to the gutter via threaded rods extending up from the gutter through corresponding holes in the uplift channel and nuts placed on the threaded rods.

The roof ice and water shield includes a bottom layer of asphalt material configured to lay against a roof surface following installation on a perimeter of the roof surface, the bottom layer having a terminal lower section configured to be adjacent a roof edge at the perimeter of the roof surface following installation, and the bottom layer having a terminal upper section opposite the terminal lower section. A top layer of asphalt material extends from the terminal lower section of the bottom layer in a direction towards the terminal upper section of the bottom layer, an upper section of the top layer is configured to create a watertight seal with the terminal upper section of the bottom layer, and a lower section of the top layer defines a flap configured to overlap the terminal lower section of the bottom layer during installation. A sealable drip edge pocket is between the flap and the bottom layer and configured to sealably envelop a top portion of a drip edge following installation.

The roof scupper overflow with sensor cooperatively engages and replaces a conventional roof opening through a wall or in a corner to prevent trash from reaching and clogging the conventional roof basket and drain. Accumulating trash builds up on the screen of the roof scupper overflow causing a foam float or buoy connected to a trash tray to rise permitting water to run under the trash trap at roof level. The trash tray is retained to a base with magnets. When the water reaches a predetermined level, the foam buoy rises pulling the trash tray away from the base allowing water to flow to the conventional roof drain basket and activating a magnet switch sending a signal to overflow sensor and a control module connected to WIFI service.
