The venting hood on the roof, in this picture,
is improperly flashed and sealed to roof
decking. No determination can be made
whether the venting hood is operable on
observation because of the amounts of
sealant and application method used are
beyond normal methods. The venting hood
is improperly installed.
Repairs will be recommended.
The asphalt shingles, on this roof, are
damaged. The shingle tabs have chipped
edges which are possibly from mechanical
or weather damage. Damage to shingles
reduces the overall lifespan of the roof
covering system.
Repairs will be recommended.
This is a picture of a severely damaged
shingle on a roof. Water intrusion at this
point is very likely and could also damage,
the roof decking, below.
Repairs will be recommended.
In this picture the flashing at the chimney
roof junction is damaged, missing in some
areas and modified by a non-standard
roof flashing method in others. Water
intrusion is very likely to occur at this point,
leaking through to the roof decking, and
could also lead to considerable costly
damage to a home.
Repairs will be recommended.
In this picture the roof shingle's improper
installation on the roof at the rake edge,
which is a non-standard method that
creates a single continuous channel
from the apex of the roof to the eaves,
where possible water intrusion can occur,
under the adjacent shingles and to the roof
decking. The water shedding design method
is not present with this installation method.
Repairs will be recommended.
This picture shows numerous trees and
limbs coming in contact or in very close
proximity to the roof. Physical damage
to the roof will occur when branch and
limb movement make contact with the
roofing system. Debris from trees can
also accumulate on the shingles and
promote algae growth, fill the gutter
system and reduce the lifespan of the
roofing system.
Repairs will be recommended.
In this picture, utility company cables are
visibly in contact with the surface of the roof.
Mechanical damage to roofing shingles
takes place at the contact point when the
cables move against the roof, reducing the
roof's lifespan.
Repairs will be recommended.
A temporary tar patch over a severely
damaged roofing shingle can be observed
on a roof, in this picture. A tar patch is
used as a temporary fix and is not
considered a reliable, long term fix since
tar will eventually crack over time, with
exposure.
Repairs will be recommended.
This is a picture of an improperly flashed
drainage waste vent on the roof. The boot
and vent has tar applied over the metal boot
instead of a metal flashing system, also
cracking is visible in the tar and at the pipe
boot junction. This should not be a
permanent sealing method because it
allows water intrusion in the gaps,
between the boot and the pipe, to enter
the roofing system. Major water intrusion
can lead to major damage and costly repairs
to the interior and structure below the
intrusion point.
Repairs will be recommended.
In this picture, the roof decking, or
sheathing, at the junction point where
drainage waste vent pipe exits through
the roof has large, highly visible moisture
damage. Discoloration of the sheathing
and evidence of water leakage is present,
on the piping. The boot and/or flashing is
probably the cause of this condition.
Repairs will be recommended.
In this picture, missing and damaged shingle
caps on the ridge of the roof and an open
ridge along with exposed nails, are visible.
Water can easily enter this area and cause
major roofing system damage.
Repairs will be recommended.
This is a picture of major shingle loss on a
roof. Roof decking, or sheathing, is visible
at the most exposed points of damage and
the remaining asphalt shingles are damaged
or near the end of it's useful lifespan.
Repairs will be recommended.
In this picture, the chimney chase has a large
gap in the siding at the roof chase junction
towards the eaves. The siding on the chase
is in contact with the roofing shingles and
flashing is not visible at this junction. Water
intrusion will occur, at that point, leading to
further damage below the chase and to the
roof decking.
Repairs will be recommended.
