Flashing is a special kind of cladding and is used in conjunction with shingles or other roofing material to create a "roofing system". Flashing can be found everywhere on your roof but in many cases is hidden by other roofing materials, siding, and wooden trim.
Flashing is any material used to maintain watertight integrity other than the actual roofing material. Flashing can be made of any material, even rubber on a membrane roof, but is most commonly metal.
COPPER Flashing & Cladding is what we do, we see it every day.
Counterflashing is the "flashing for the flashing". It's purpose is to keep the water from getting behind or under the edge of the flashing. When properly installed, the horizontal edge of the counterflashing is inserting into a groove in the mortor joint called a "reglet".
To make it a little more confusing, counterflashing is often refererred to as "flashing".
The difference can be seen below...
This triangular shaped piece is a standing seam panel -the flashing. It is being protected by the stair-step shaped counterflashing. In this case, it has been face applied instead of inserted into the ground horizontal mortor joint or "reglet".
Large amounts of black sealant smeared over the horizontal joints is no substitute for a correct installation
We are replacing this, it is not our work!
This copper pan, extending under the shingles, is the flashing. The pan has a vertical bend (like the standing seam panel above) which extends behind the reglet counterflashing. It has been properly inserted into the reglet after the old sealant has been completely removed.
This is our work!

areas of your home. It ensures material longevity by protecting materials which are prone to degradation. Fascia, trim, bays and cupolas are all examples of areas where exterior cladding is used
