What roofing detail is the gable flashing used for?
The gable flashing shapes and covers the linear connection between the roof area and a vertical gable or wall. Its L-shaped profile provides separate arms for the two surfaces but does not by itself define the entire waterproofing assembly. The underlayment, roofing material, upper wall termination, and fasteners must be coordinated according to the specific construction.
What are the dimensions of the "Gable flashing / 2m"?
The profile is 2 meters long and has two main arms of 140 mm each, shown in the technical diagram as 14 × 14 cm. Small reverse bends are formed at the free ends, whose dimensions are not separately indicated. Before ordering, it should be checked whether the two arms cover the necessary areas on the roof and wall with the intended overlaps.
Which variants of the gable flashing are available in the product?
The gable flashing has a glossy finish and two color options: RAL 8017 and RAL 7016. In Shopify, they are separate variants with their own SKUs, so the color must be selected before adding to the cart. The RAL code coordinates the flashing with the other sheet metal details, but the perceived shade from a photo may differ from the actual surface.
Is the 140 × 140 mm gable flashing universal for every wall?
No, the fixed 140 × 140 mm profile is suitable only when both arms and the angle correspond to the actual assembly. The slope of the roof, wall irregularities, height of the upturn, thickness of the covering, and space for upper sealing are checked. For different geometry, another profile or custom cutting is needed, rather than forcibly bending the finished element.
How are two-meter flashings calculated for a long gable?
The quantity is determined by the linear length of the connection divided by the effective length of one profile after overlapping. The nominal 2 m is not equal to 2 m of finished detail because adjacent elements must overlap in a direction that does not retain water. The result is rounded up and additional pieces are added for bends, starts, and ends.
Is the gable sheet metal alone sufficient for a watertight connection?
No, the profile is only the visible sheet metal part of the detail. A reliable connection also depends on a properly installed underlayment, sequence relative to the tiles, overlaps between profiles, suitable fasteners, and protected upper termination to the wall. Specific sealants are chosen according to the substrate and system; it should not be assumed that any silicone compensates for improperly installed flashing.
