Why Power Wash?

• Remove black mildew and roof fungus from shingles, to beautify your home and reduce summer cooling costs
• Removal of Algae, Moss & Lichen that also Damage the Roof & Shortens Roof Life.
• Clean leaves and branches from gutters which can stop up downspouts and cause fascia board rot

• Let the professionals do it; Pressure Washing a roof and cleaning gutters can be dangerous. A roof when wet becomes very slick, especially on a roof with a high pitch. When you are moving a ladder, on a ladder or a roof you should be very careful and comfortable- we perform exterior cleaing from ladders continuously, so we are always paying attention to best practices from heights. Let Shield Team Power Washing Services handle your roof wash so you can avoid the hazards of high ladders and slick roofs.

The ugly, dark stains that are so prevalent are caused by a very hardy “blue-green” algae, Gloeocapsa magma, that thrives on the asphalt (also called fiberglass or composite) shingled roofs in much of the country, especially in the more humid areas. Growth normally starts on the north side as well as shaded areas of the roof. As the algae grows, it holds moisture allowing the growth to accelerate. Thus the roof stains get worse and worse over time as well.

Algae, moss & lichen spores are carried by wind, birds, squirrels, etc. If your roof is currently clean, it likely won’t stay that way if other houses in the area are already stained.

Years ago, stains on asphalt shingled roofs were not a significant problem. Today it is a big problem because the design of asphalt shingles has changed over time. For the last 30 years or so, asphalt shingles have been manufactured using limestone as the base filler. Unfortunately, limestone is a favorite food of this strain of algae. Due to a lack of food, algae used to starve to death when it landed on your roof - now it thrives on your roof.

There are other types of stains and growths found on roofs. Green roof stains are often caused by mold and mildew. Lichen & moss are common growths found on roofs in some parts of the country. Roof-Be-Clean â also removes and prevents stains and growths caused by all these organisms.

It is bad enough that algae causes ugly roof stains, unfortunately it also damages the roof The algae takes root on the shingles dislodging the granules which protect & color the roof. It holds water to the roof's surface and can cause decay & rot of the roof's underlayment. Not only is your roof being discolored by the algae, but it is shortening the life of the roof leading to an early roof replacement. Moss and lichen do the same - however the damage normally occurs much faster.

What Happens if you don't maintain your deck?

Why maintain your deck? Rain, morning dew, and even melting snow are quickly absorbed by the unprotected wood, causing it to swell and soften. The sun's heat causes drying, this makes the wood shrink. These cycles of wet and dry, swelling and shrinking, cause wood to warp, split and crack. Consequently, this results in a
