ROOF CLEANING SEATTLE WA

All roof surfaces, especially asphalt shingles can accumulate debris and can become breeding ground for moss, algae and lichen.  Keeping your roof clean not only improves the appearance of your home, it can dramatically lengthen the life of your roof.  Any organic matter on a roof will trap moisture, which means that shingles designed to have water roll off and dry quickly will stay wet for hours, even days after a rainfall.  This prolonged exposed to moisture erodes the surface of the shingle and can cause the wood under the shingles to decay. This is a particularly pernicious problem in the Pacific Northwest with 9 plus months of rain a year.  I have been on the roofs of dozens of homes across the greater Seattle area and have a first hand knowledge of how fragile a roof is.  Unlike lots of other larger companies, I do not use any pressurized or power washing on roofs given how important it is to save as many asphalt granules as possible. The method I use to remove moss and all other growth and debris from a roof is by hand.  It is difficult and time consuming work, but it is the safest way to preserve the integrity of the roof.  Also unlike many other companies, I do not use harsh chemicals on the surface of your roof to remove moss.  Many roof cleaning companies simply spray chemicals on your roof and wait for time and rain to do the work.  While this can kill the moss, it does not fully remove it. Several of my clients have called me to remove the moss that a previous company simply sprayed and killed.
