Syracuse Roofing: Article About Reasons To Clean Asphalt Shingle Roofing
Every homeowner, at some point or another, may be confronted with the issue of cleaning an asphalt shingle roof. It is important to consider the procedures and techniques behind such a task. Speaking with a Syracuse roofing specialist may be helpful.
Investing in a roof cleaning may be a good idea if the homeowner is looking to sell the house in the near future. A thorough roof cleaning improves the appearance of the entire home. Roof cleaning removes the black streaks and brown stains caused by algae, moss and lichens.
If algae, lichens and moss only caused a problem with appearance, perhaps it would not be so necessary to clean the roof. However, all three are harmful to asphalt shingles over time. Each of the organisms negatively affects shingles in its own way. Algae and moss use the material within the shingles as a food source. Lichens, on the other hand, may be acidic. That acid can eat into the shingles. Further, lichens have roots that burrow into the shingles, which weakens them over time. The longer these organisms remain, the more damage they cause the shingles. They must be cleaned off the roof in order to prevent long-term damage.
If lichens, moss and algae are permitted to grow on the roof, they may begin to eat into the sheathing and roof deck and cause rot. Once the wood begins to rot, moisture may seep into the wood and encourage the growth of mold.

If left unchecked, this mold can penetrate the house and cause health risks.
In addition, a dirty roof, whether from the presence of dirt, algae, moss or lichens, is not as energy efficient as a clean roof. Debris, dirt and harmful organisms can be a barrier to a roofing system's performance. They can cover the shingles so that the shingles fail to reflect sunlight well. In this scenario, the shingles will begin to absorb heat and increase temperatures within the attic space. A roof that absorbs heat increases cooling costs.
Roof cleaning, once done, is a preventative measure. If a roof has been cleaned by professional roofers, the chemicals used to clean the roof may be reapplied every year and a half to every three years in order to keep the roof free from destructive organisms.
Roof cleaning in itself is preventative in another aspect. It extends the lifespan of the roof. If a roof is not cleaned, it may become damaged to the point of needing to be replaced. Replacing a roof is much more costly than simply cleaning it or having it professionally cleaned.
Many reasons exist for cleaning an asphalt shingle roof. A homeowner considering the benefits of cleaning a roof may choose to speak to a roofing professional.
