Drip cap or not

arnoldk | Posted in General Questions on

Hi,

These window are install below a 24″ roof overhang and normally I would still install a drip cap cover the window trim. The difference here in this case is the windows are install to a stained 6″x8″ wood beam which will remain exposed.

Would caulking (when the weather warms up) the exterior trim where it meets the wood beam and add a couple of additional coat of paint on the top of the trim be sufficient or should I still install a drip cap?

Thank you,
Arnold

    Could you take a photo from a little farther away? It's hard to understand what you have without more context.

    How much rain and wind do you get? How far above the window is the roof overhang?

      Hi Michael,

      Two pictures show the front and back of the sunroom while the third one is the side with the gable end. Note that there will be two triangle window install there but the supply forgot to include the nailing flange.

      Thank you,
      Arnold

        I see, thank you, these photos help a lot. I don't know of a way to make that assembly reliably watertight. I would cover the natural wood with a WRB and trim.

    We're going to maintain the stained post and beam as they are and I have already taped using 3M 8067 the windows to the post & beams.
    I am wondering if it makes any sense in adding a drip cap on top of the trim shown in the above picture (not yet installed)? In in situation, it would mostly serve to protect the LP Smartside trim.

    Any thought would be welcome.

    Thanks,
    Arnold
