 A home
inspection on this house in Hollywood,
Maryland revealed rotting
T-111 wood siding and plywood damage in the
attic; so we're digging in . . .
|
As expected,
we have discovered plywood damage all the way
up the exterior wall and around the
chimney. Now for the back . . . |
It's pretty
bad plywood rot around the chimney, indicating
that the chimney flashing was leaking for a
long time. |
It's the
same story on the back of the chimney. |
. . . and on
the right side as well. |
 |
OK, we've
strategically cut the 1/2" plywood, removed
it, and replaced with new 1/2" CDX
plywood. We used #10 coated sinker nails
to fasten the new roof deck to the roof
rafters. |
New plywood
was also installed on the right side of the
chimney. |
. . . and on
the rear of the chimney as well.
Evidently the flashing was leaking around the
entire perimeter of the brick chimney. |
For the next
step we've installed 30 pound roofing felt in
the roofing and wall areas. |
Roofing
tarpaper is applied around the chimney as
well. |
Now it's
time to start nailing the 25 year 3-tab
shingles. |
Notice the
orange plasticaps which are the preferred way
to attach roofing felt to the roof deck. |
 |
Integrating
the step flashing into the shingles next
to the wall is the proper method for
waterproofing this area. It's the
overlap and weaving action that makes this
system work properly. |
After the
step flashing has been applied in the same
manner around the brick chimney, the custom
made aluminum counter flashing is secured and
permanently sealed with Geocel Tripolymer
Sealant. |
The custom
made flashing assembly will keep the chimney
and roof deck area leak free for years to
come. |
It's hard to
imagine the amount of work caused by a simple
chimney leak. A simple roof
maintenance program could have
eliminated these repairs and expense. |
The roofing
and flashing part of the project has been
completed and now it's time to install the
prestained T111 wood siding and the prepainted
rake board and trim. |
A good
amount of reconstruction work was done here;
all resulting from a little water leak over a
long period of time. |
