Flexible Drip Cap Flashing for Exterior Arched Openings

We looked for years for a quality drip cap product to sell with our custom made exterior mouldings.  
We finally found it with this polypropylene drip cap made specifically
for protecting radius top windows and doors.


We now stock this flexible drip cap product in all four colors so we can
supply it along with our custom made wood curved mouldings.

This curvable drip cap flashing is flexible enough
to bend around a tight radius opening yet rigid enough to
maintain a smooth matching curve.

(Note:  scroll to the bottom of the page for detailed specification drawings.)



There are four available colors for this flexible flashing:


BLACK
BROWN
WHITE
and
PAINTABLE BLACK
(not shown)

It is supplied in 6' lengths and includes seaming tape and instructions for longer runs.

The cost is $ 3.00 per foot in 6' lengths.
(Note that you need to call to order...there is no online ordering.)

This flexible drip cap solves the serious problem of how to keep
water out from behind exterior curved mouldings.  Without proper
flashing water gets behind the moulding and channels down
to the hidden window jamb and wall framing below.  Over time
this rots out the trim, window or door frame and the wooden
side walls of the building.  We make many replacement mouldings
for situations where proper flashing was not used and the original
trim, and often much more, has succombed to deterioration..

IMPORTANT:  caulking trim to prevent water penetration is
at best a temporary solution.  Even though high quality caulks are
guaranteed to last for many years, they do not prevent moisture
from seeping through in a horizontal sealing application. 
Within a few years of installation wind, weather and wood
movement will cause the caulk seal to fail and water WILL
penetrate behind the window trim. A quality window or
door installation will always incorporate some form of water
penetration protection, either in the form of a wide ceiling
overhang or proper bendable flashing, such as copper,
lead, vinyl or this new polypropylene product.
  





The flashing cleanly hugs the shape of most any
radius top window or door.  It is available in
6' lengths and multiple sections are easily joined
together for longer runs.  One piece is long enough to
protect a typical 36" diameter 1/2-round opening.







Here you can see special raised lips that force water towards
the outer edge of the flexible flashing.  The drip cap is easily installed
right over the sheating or house wrap just prior to installation
of the siding.  Note that a few staples or small nails will
hold  the drip cap in place until it is covered by the siding.


 




In this photo you can see the integrated triangular kick-out
panel at the lower end of each flashing section that shoots
the water out and away from the side of the building.
This may be cut away if your application works better without it.
