Cedar Roof Cleaning & Treating
cedar roof is slowly being destroyed by fungus and the elements
of weather. The fact is, unprotected wood weakens and decomposes
as it loses natural oils. Although natural cedar oil,
thujaplicin oil, is a good preservative, it is depleted from the
wood in three to five years.
Heat and sunlight shorten wood life through cellular breakdown—the
effect doubling with each 18-degree F. rise in temperature.
Water damage occurs when moisture builds up and leaches
thujaplicin oils from the wood—exposing the wood to damage
from fungi, lichens, mosses, and other decaying organisms.
Without care, a cedar roof will disintegrate from drying stress and
internal rot. Untreated wood leads to irreversible cracking and splitting
damage. Brown rot (dry rot) develops through the growth of various fungi.
If left untreated, it penetrates into the wood—feeding on the remaining
cellulose until only a brown or black residue remains.
will pressure wash your roof to remove fungi, lichens, mosses,
and debris. We use a very gentle 1600 psi washing system that
uses water volume, not pressure, for effective and safe
cleaning. After cleaning, we will repair and replace any
weather-damaged shakes and shingles.
cleaning, when your roof is dry, we will spray our specially
formulated wood stain & preservative. We use Rodda’s Wood
Preservative—non-toxic and fire-resistant. After treatment,
your roof will have a silver-gray look, like natural sun-dried
cedar. This comes with our 5-year moss warranty.
