Trim is an essential part of a metal roof. Trim is what helps seal all joints where a transition is made in the slope and direction of a roof. It also has many aesthetic qualities. For some of the trim listed below, there will be several different trim profiles to choose from based on the look you would like to achieve. But for now, we’ll start off with what kind of trim goes where.
This trim will be found anywhere two rising roof surfaces meet one another.
This trim is found anywhere a sloping edge ends, such as the end of a gable or the end of a dormer.
Eave trim is installed on the lowest edge of the roof. Its main purpose is to give a finished look to the roof. If gutters are requested, they would be installed directly below Eave Trim.
Downspouts are used when gutters installed. They drain water from the gutters to the ground.
Any time a vertical wall surface meets a sloped roof surface, Sidewall flashing is required in order to keep water from getting underneath the roof panels. A similar trim is also needed around chimneys.
Endwall flashing is needed anytime the high side of a roof plane meets a vertical wall. Siding or counter flashing can be used to cover the endwall flashing on the wall side and outside closures are used between the flashing and the metal panels. A similar trim is needed around chimneys.
Valley trim is required anywhere two roof surfaces meet to form a valley. The Valley Trim is installed underneath the roof panels to help guide water and keep it from getting under the panels.
Any time a roof pitch changes, transition trim is required. It is used to keep water from getting under the roof panels.
