Metal Roof Valley

A metal roof valley is a specially designed channel, typically made of metal, placed at the intersection where two sloping roof sections meet. It helps manage water runoff.
Metal Roof Purlins

A purlin is a horizontal board on roofs for attaching metal. They span the roof deck, are spaced 3 feet apart, and are fixed to the rafter. Radiant barriers can replace felt under purlins for a better underlayment.

TPO Skin Overlay

TPO skin refers to the process of installing a layer of roofing membrane over an existing roof surface. Instead of completely removing the old roof, a new TPO membrane is placed on top.
ISO for Drainage

ISO Boards are rigid insulation sheathing commonly used in flat roofs. They are tapered, allowing construction of a custom slope that tapers toward the roof drainage system. The drainage system is reinforced with TPO tape and the entire roof is coated with membrane.
