What to Expect on the Roofing Inspection Roane
County, TN Quality Home Inspections
The roof inspection portion of the home
inspection covers the visible aspects of the home's roofing system.
During the roof inspection I will be looking at the general
condition of the roofing material and looking for current issues and
areas that could be problematic later on. The primary job of a
roofing system is to shed water. Roofs aren't meant to be air tight
or water proof, but should shed water down to the gutters where the
water can be safely directed away from the house. If water gets hung
up anywhere on the roof it can cause water leaks into the attic. For
example, a wide chimney missing a chimney cricket can capture
water and hold it on the roof long enough to create a leak.
Typically, asphalt shingles
have a life expectancy up to 20 years. Architectural asphalt
shingles can have a life expectancy up to 30 years. Of course,
extreme weather conditions, moss, and trees that are too close can
shorten these life expectancies. Metal roofs can have life
expectancies ranging from 40-80 years, but keep in mind roofs of all
types occasionally need maintenance.
Below are some common defects
that may show up on your home inspection report.
I want to see a drip edge on the edge of the roof
to protect the wood from rotting due to contact with moisture. Below
is an example of a missing drip edge.
Moss growing out of the shingles is an
obvious defect that we run into a lot.
Moss holds moisture down onto the
shingles, which can shorten their life expectancy,
and, over time, its presence can create points of water
penetration through the roof. Ridding your roof top of moss
growth should be part of your regular roof maintenance along
with making sure your gutters are cleaned out.
How do I keep moss off my roof?
For asphalt shingled roofing, nail pops
are one of the issues that stand out to an inspector. Nail
pops is a nail that hasn’t been fully driven down. With this
condition, you will notice that shingles do not lay flat.
You‘ll see one side or the other sticking up slightly. This
condition can create an opportunity for water to enter into
the roofing system.
On metal roofs I pay particular attention to the screws. Are
they too loose or too tight. If they are too loose that
could allow water to get in, or worse make the roof less
structurally sound in the event of a wind storm.
Below is an example of vent pipe flashing
that is not covered correctly by the roofing shingles.
Another part of the roofing inspection
is satellite dish connections. You could have a leak in
your attic and not know it, simply because fasteners on your
satellite dish were not properly installed. It’s best to
avoid installing a satellite dish on your roof to start
with, but if you have one already it is a good idea to
monitor your roof in that area closely. The screws should be
sealed with a roof patch tar or a material specifically
designed for sealing to asphalt. Besides screws leaking,
satellite dishes tend to create a barrier to water,
preventing it from running straight down and off your roof
as quickly as it normally would. Water can pool up at the
base of a dish and this can lead to a roof leak eventually.
Below is another example of a defect that
if found would be reported on your home inspection report.
Tree limbs should not touch or hover over a roof.
This defect can cause the roof to
deteriorate faster underneath the tree limb due to moisture
build-up. Also tree limbs hovering over a roof could fall
and cause damage to the roof.
Your inspection report will combine
everything observed in every visible area of the home to
give you a full picture of the condition of the home. For
example, your report will reflect the findings in the attic
space and how they relate to the roof. Most signs of leakage
are most readily observed in the attic and can usually be
tracked back to problematic areas listed above such as
failed flashing, satellite dish connections, lack of chimney
