The first problem in this installation: Not enough
air is allowed behind the wood shingles to make the wood
dry between rain falls and seasonal changes. Much of this
could have been prevented by using a pine tar and organic
linseed oil mixture.
In Europe, we have seen examples of wooden shingled roofs
that are over a hundred years old. These roofs have been
maintained every 10 to 20 years with pine tar and organic
linseed oil. Please use Allback's
purified linseed oil to prevent mildew. Problems with
wood, always comes down to the paint or wood preservatives
used. You never find a problem with the wood when using
organic purified linseed oil. Organic linseed oil and the
organic linseed oil paint will last for generations and
is easy to maintain.
