Roof Cleaning

The black roof stains common to our area are actually an algae called Gloeocapsa Magma.  This type of algae is often referred to as “roof mold” and loves to grow in humid and warm climates. This algae usually appears first on the North slope of the roof where there is the most shade and moisture. Rain then spreads this algae down the roof, causing black streaks. This algae feeds on the limestone filler used in roof shingles and gradually begins to break down the protective granules, causing them to fall off into your gutters...This causes the roof to deteriorate and also lessens it’s ability to reflect heat rays.  If left untreated, this algae will reduce the life of your roof, decrease your home’s curb appeal, and increase your home’s cooling cost. If you are trying to sell your home, it can also create a very negative perception in a prospective buyers mind, as they may feel the roof is in need of replacement. A professional roof “soft-wash” will restore that healthy “like new” appearance to your roof, extend it’s life, increase your property value and dramatically improve curb appeal.

Before; ugly, algae stained roof. Probably lots of discoloration from car exhaust, smoke from burning leaves and other environmental contaminants as well. The customer had a lot of doubt that the roof would come clean.

After; same roof, completed with a low pressure wash. This looks like a new roof, and the house sold shortly after. The home had been on the market for a long period, prior to the cleaning!

One of the worst roofs we've ever seen. This is what can happen if neglected for too long. This moss holds water like a sponge and over time can can cause non reversible damage to your roof.

It almost looks like the roof has green carpet. We urge you to call us at first sight of this green moss, so we can safely remove it before more damage is done to the roof. This one is already almost too far gone to restore.

Upon multiple treatments, and time, we were able to remove the moss growth. Once removed, you're able to see the pitting where granules were eaten away by the living organisms! It still looks so much better, and there was no use of high pressure use
