If you look at the picture above, any water that's
rolling off of the upper deck can easily work its way down, following
the path of the black arrows, on to the top of the 2 x 6 post cap.
Once water starts to accumulate for long periods of time, it will start
to work its way into the smallest gaps or cracks, eventually creating
water damage problems for your these areas of your wood deck.
Home Repair Tip: If you notice the lowest black arrow is pointing to the
biggest water damage problem area. All horizontal areas like these need
to be protected and maintained regularly by caulking any cracks or gap's
and then painting.
