HOW CEDAR ROOFS FAIL
YOUR ROOFS CEDAR SHAKES DECOMPOSE LIKE COMPOST
Cedar Grows Like This…
Straw-like filaments draw nutrients from the ground to the branches, and over the years become filled with resins and oils. This heartwood, in cedar, is the weather-resistant shake material of choice. The older it is, the more full it is of this natural preservative. Thus, old growth cedar is preferred, but rare in today's market. The structure of the wood is mainly made up of lignin, which, in cedar, is not particularly strong. When resin depletes for any reason, cedar weakens.
Once wood is cut, it is dead, and nature sees it as a prime candidate for reduction into soil. Your cedar shakes or shingles are a prime target for decomposition.
Microbes, in thousands of forms, are designed by nature to reduce dead wood to soil. Friends of nature generally, these are enemies to your cedar roof and your pocketbook!
| Slime Mold Algae Mildew | These three pervasive types cover entire wood surfaces wherever there is moisture, warmth and shade. They feed on oils and resin in the wood, are generally greenish and create a slippery surface. |

ROT SPOTS
One of many types of Algae, Rot Spots grow like this…
Microbes, each with hundreds of sub-groups, are carried in the air in the form of spores. A group of spores attack the weakest wood first. They colonize. Any success in de-composition creates an environment ideal for other types of microbes, and they attack, in wave after wave of progressively more damaging species.
The rot spots begin small, at the weakest points, and grow. Rot spreads exponentially as water ingresses to the underside of shakes.
HOW DOES ROTBAN "EAT" ALGAE & OTHER MICROBES?
These destructive microbes need an acid environment to flourish. ROTban works by neutralizing the acids. It clings to the cells and remains in the wood for years, re-activating with every rainfall. Thus it eliminates rot producers and protects against re-colonizing for years.
Do it now, before the rot starts! Colony establishment becomes most damaging by about the 10th year of your roof's life. By 19 your roof will be "gone",unless you act. Call Professional Roofing Group now! Repeat Action Sterilization Keeps Stains, Moss and Damage Away.
ALGAE DAMAGES SHINGLES
"Millions of homeowners across the country are learning that the black streaks are not just a barrier to maintaining an attractive roof - there are many other complicating and potentially costly repercussions." Roofer Magazine - Aug. 1994
Specially made granules adhere to the bitumen of the asphalt shingles. They form the coloured surface, and are there to protect the bitumen from "cooking" in Ultra Violet Rays.
In the moisture, shade and warmth of mild climates, an algae known as Gloeocapsa attaches to the granules and form a "colony". It is dark in colour to protect itself from the U.V. Rays.
Over the years, the colony grows between the granules, and on the bitumen. Gradually, damage is done to the bonding of the granules to the surface, and some granules fall off. The bald spot left on the bitumen leaves it exposed to UV rays, which damage it.
The sun causes curling and cracking - premature failure.
