Limited Inspection
Date of Inspection: Wednesday,January 20, 2016
Property Address: 11110 SW 7911 Avenue, Tigard, Oregon
Client Names: Brian and Lora Helmer
Purpose of Inspection:
After moving into the home, the Helmer's have noticed a crack in the ceiling of the master
bedroom appear and lengthen over time. They wish to have the roof framing and specifically
the skylight framing checked for structural integrity. Determination of the cause of the cracking
is also of concern. They wish to know if this is an ongoing issue in need of repairs or something
of relatively minor importance.
Scope of the Inspection:
Drywall is to be checked for any signs of moisture, or other potential cause of the cracking.
The framing of the roof and ceiling support structure is to be checked for structural integrity.
The framing of the skylight walls is to be checked for structural integrity.
Observations:
The cracking in the
ceiling runs from the
NW corner of the
skylight opening at the
ceiling to the west,
then ends at the
exterior corner of the
master bedroom
closet. The photos at
left and below show
this cracking.
Crack runs from left corner
of the skylight to the
outside corner on the left.

A second crack, or more
accurately a ridge, has
developed near a
recessed light located to
the right of the skylight in
the photo above left.
That ridge is shown in the
adjacent photo. It runs
from top center to
bottom center in the
photo.
The attic space above the area of the cracking was accessed and entered by the undersigned.
The framing of the roof and ceiling support is a truss system of 2 x 4 wood components and
metal attachments between chords and webs. The trusses were checked for signs of any
structural issues such as cracking, and disconnected or broken components. No deficiencies in
the framing were evident. See photos below.

drywall in the
background on the right
side.
The attic side of the drywall in the area of the cracking was observed. No water or other
staining was present that indicates a roof leakage issue. Nor was there staining evident on the
bedroom side of the ceiling. The cracking and ridge in the ceiling are both at drywall sheet
edges where joint compound has been used. These are the typical weak points in drywall.
No other signs of movement or stress were noted in the attic around the area of the cracking or
ridge. The plywood sheathing was observed along with the truss framing and framing of the
skylight well.
The skylight wall framing appears to have been performed in a workmanlike manner. 2 x 4
studs were cut to fit snugly and to match the truss chord angle of the two trusses used to
construct the skylight walls. Nailing appears to have been performed with a finish nail gun, not
a framing nailer. Several finish nails were present at each connection. No signs of movement in
the framing of the skylight walls were noted.

corner of the skylight
wall framing. Nailing is
evident here.
The wall corners and intersections at the ceiling were observed in the bedroom and in the
closet at the west end of the crack. No other cracking was present, nor any other signs causing
concern or suggesting a source of the cracking.
Analysis:
The locations of the cracking and ridge are fairly typical, running from corners and along the
drywall /gypsum board edges. As with most small cracks, the source is often very minor and
not readily determined, unfortunately. They also typically appear and may lengthen for a
while, then cease any further movement. Most of this type of cracking appears during the first
year after construction, so this is somewhat unusual, unless the skylight was recently added. It
is probable that some event has caused this cracking. Earth movement or other events such as
a heavy truck passing by could cause the movement needed to produce this
cracking/movement.
I believe this cracking will most likely cease to increase in length or width or increase only in
small ways. The size of the cracking does not indicate a significant structural deficiency at the
time of this inspection.
I would advise periodic monitoring for signs of continued movement or changes in the width of
the cracking. If significant changes are noted, further evaluation would be suggested as this
may reveal a deficiency not previously apparent.
