Dry Rot
Dry-Rot must be repaired before the new roof is applied, so it is
very important to locate and determine what
areas of the roof have dry-rot damage. We have provided some info. on
how to locate, determine and
describe the different areas of the roof overhangs that are most likely to have dry-rot damage.
Most home owners will get multiple roof estimates and what info.
they were given by the estimator may
be the deciding factor as to who gets the job. So we have provided
some info on dry-rot to consider
when giving roof estimates. Homeowners like to know that you are
very knowledgeable and they also appreciate all the options and
considerations you point upon reviewing your
estimate the customer notices you don’t mention any dry-rot repairs
needed, but one of your
competitors does in his estimate. Who do you think will get the job?
And if you do get the job and they notice
you did not repair this dry-rot after the new roof is applied that
may be grounds for them not to pay you
or they could make you repair it which would require tearing off the
new roof . So you can see why
this is important, by using our provided info. combined with
using Roof Estimators
Contract/Proposal forms that you can give to the customer via mail,
fax, or email attachment, you will keep
the upper hand on
all your competition.
How to Locate, Determine and Describe Dry
Rotted wood under the over hangs of your roof. Refer to picture below:
1.
Roof Sheathing
is nailed
to the top of the rafters on the
overhangs
of the
roof
. Usually its plywood
or
V-rustic,
V-rustic boards are re-sawn with lap sides, they're
usually 1”x 8” or 1”x 6” re-sawn side down.
2. Fascia board
is nailed
to the end of the rafter tails. Usually they’re re-sawn 1”x 6”or 2”x
6”
boards. The
Rafter board size can determine the size of the fascia board. Gutters are installed
flush against the fascia.
Not all houses have fascia.
3.
Rafter Tails are the end of the
rafters on the over hangs of the roof. Usually
they’re 2”x 4”, 2”x 6”
or 2”x 8”.
4. Barge Rafters
are
usually 2”x 6", 2”x 8”, or 2”x10” they're the last piece of wood on
a gable end facing
the weather.
The rafter tail in the picture could be the barge rafter if the roof were
to end there.

parts.

Locating Dry Rot:
Dry Rot is soft when probed, when the wood is pushed with a
probing tool
like a long steel rod the wood will be spongy,
allowing the steel rod to sink into the wood
making little
push holes in the wood like in this picture, this was caused
from water damage.
Where non-dry rotted wood is hard and
dense.This Picture is a good example of dry rot on
all 3 Different Parts of the over hang of a roof.
To repair the dry rot in this picture the roof (s) will have
to be removed around the dry rotted
area, and the
dry rotted wood will be Cut out or pulled out and new wood
will be installed, and the roof area
re-installed.
Dry Rot
Dry rot is probably the nastiest risk to timber. It is a fungus that
will attack and destroy
timber very quickly and it will
penetrate brick walls to get to more timber. It thrives in
moist, poorly ventilated conditions indoors. It can be there unseen
for many years, the
first you may know of it is when the symptoms appear. It thrives in
those areas of
the house which are not
seen very often, such as under wooden floors
and in the roof space. Dry rot normally arrives as airborne
fungal spores
which finds a welcome on wet timber.
What
to look for:
Dry rot is easy to identify once you suspect you have it and know
what to
look
for.
In the early stages, the spores send out fungal strands along the
timber
and through/along any wall. These strands can became quite dense
to
form a mass like cotton wool penetrating, and destroying the timber.
The fungus can also become attached to carpets covering infected
timber
floors.
The final part of the fungal life cycle is the formation of a
mushroom-like fungus,
which produces millions of new spores which the
air carries away to
look for
some more damp timber. The first sign of
dry rot is often its
distinctive
musty smell when you lift a floorboard or
even just the carpet.
Dry rot is an equity eater and it will attract
termites. They love the damp rotting wood.
So getting it repaired as soon as possible
will save you money.
