DRY ROT (Scroll down page for Dry Rot Estimate Request)
How to Locate, Determine and Describe Dry Rotted wood under the over hangs of your roof.
Refer to picture below: (for example of these 4 different described parts of an over hang of a roof.)
1. Roof Sheathing on the overhangs of the roof is nailed to the top of the rafters. 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” Rough 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.
Rafter size can determine size of fascia. 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 ended at it.

Roof over hangs are at the bottom of the roof where the gutters go, they extend out past your house.
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. T
he 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.
