Copper Counter Flashing

Also referred to as brick flashing, this is the metal work that ties a roof area together with a masonry wall. The shingles or other roofing material, and "step flashing", must be installed prior to the installation of the counter flashing. If clay or concrete tile roofing is selected, the step flashing is not used in this area, but is replaced by a different type of flashing made specifically for this purpose. The counter flashing is then installed in the normal manner, but before the installation of the tile. We manufacture and install all of the various flashing detail items necessary for these types of roofs.

In some cases it is advisable to precede the installation of the roof materials with "Ice & Water Shield". This is a self-adhering waterproof membrane that provides an invaluable level of protection against ice dams and wind-driven rain infiltration. Such areas would include chimney saddles and valleys that dead-end into a wall. It is also often used along eaves, to prevent infiltration into soffits during periods of heavy snow or ice accumulation.

Counter flashing can be installed by the straight method, stepped method, or in the case of copper hoods with a "swoop", the curved method. Each method is shown below.

(Note: It is easy to confuse the term "stepped counter flashing " with "step flashing". Stepped counter flashing looks like a staircase on the side of the wall. Step flashing is each individual piece of copper, aluminum or galvanized steel that is bent to a ninety-degree angle and inserted between each shingle or slate at each roof-to-wall junction. Counter flashing is then installed so as to cover and seal the step flashing. We recommend the use of copper (preferred) or aluminum step flashing when using copper counter flashing to avoid or minimize corrosion due to the use of dissimilar metals.)
