While many of the building failures
I investigate are caused by some
structural oversight — like a weak
framing member or an inadequate
connection — just as many have
another cause: water intrusion. Over
the years, I have seen many cases of
decayed framing, water-damaged interiors,
and opportunistic carpenter
ants nesting in wall framing, all
because the builder failed to provide
weathertight detailing.
Roofs generally receive a lot of
attention, but keeping the water out
of walls is equally important. It's easy
to overlook important details when
jobs fall behind schedule or the work
gets rushed because of impending
rain. Here are the most common
trouble spots I see, with advice on
proper prevention.
