Roof Moss Removal Seattle

Leave a comment

Removing Moss from Roofs

The moss on your roof has been introduced to your substrate by airborne spores that periodically pollinate their surroundings. In high winds these spores travel. Regardless of where it came from we are going to be discussing how it spreads, what damages it causes to roofing materials and the proper way to remove it.

How Moss Grows

Moss spreads thru its spores, it has no vascular system. It is of the plant family Bryophytes. Bryophytes absorb water through their leaves. It receives nutrients by absorbing it through photosynthesis. Since it has no vascular system it must find a damp place to live. Roofing makes a very great abode, as it is one of the dampest places on a home. Seattle has an average of 150-days of rain a year, making Seattle one of the rainiest places in America. The combination of location and environment make roof moss in Seattle, a normal occurrence.

Damage to Roofing

Moss grows in mats 1-3 inches tall. These mats act as a dam and do not allow water to flow freely down your roofing into your gutters. Water begins to pool at portions of your roof affected with moss growth. The shingles underneath aren’t allowed to naturally repel water or breathe.  In a very short amount of time, when left untreated, moss will completely destroy a roof.

Methods of Removal

There are several methods of removal that are practiced by roof cleaning contractors in Seattle:

  • Power washing
  • Manual Scrubbing with a  stiff bristle brush
  • Chemical Treatment

Chemicals to Kill Moss

No method is complete without the use of a biocide after the cleaning has been done. The preferred chemicals to kill moss are:

  • Zinc Powder
  • Copper Powder
  • Sodium Hypochlorite

Roof cleaning contractors in Seattle know that cleaning a roof, without administering of moss inhibiting chemicals is likely to cause moss to return very rapidly. When applying chemicals the manufacturer’s directions for proper application should be observed. Improper application or insufficient use of chemicals when mixing will cause damage to the roofing material or dilution to potency not suitable for killing moss.

Conclusion

Moss is a very destructive force to roofing materials. Proper application of moss killing chemicals can only be administered by an experienced roof cleaner in Seattle. There are several methods of roof cleaning but all must end with the application of moss killing chemicals.

Roof Cleaning in Bellevue, Washington

Bellevue has some of the steepest and highest roofs in the area. Roof Cleaning in Bellevue are practiced in an  similar manner to any other roof cleaning in our area , however due to the steepness of the roof slopes, certain safety precautions need to take place. These precautions are:

  • Safety Monitors: One man is constantly looking out for his partner from the ground, while another performs the actual work.
  • Safety Straps in multiple locations: based on our experience  a home in Bellevue requires 3 straps or more. This can drive up the cost on a roof cleaning in Bellevue, by up to $150 dollars as compared to other areas.
  • The volume of cedar roofs is much higher. A big percent of our jobs in the area are cedar shake cleanings. Cedar shake cleanings require safety precautions not found on asphalt shingles.

The residents of Bellevue and the eastside take great care of their homes and are savvy when it comes to making decisions on the right contractors to hire. Based on our professionalism and track record for completing jobs on time and on budget we have received an enormous amount of referrals from the area.  We hope to continue to be able to serve the residents of bellevue and look forward to many more years of visting this great city and its wonderful residents.
