Why should I have my roof cleaned?

(Besides the fact that it looks bad)

Why should I have my roof cleaned?

The black streaks and algae you see are eating away at the roofing material. As time goes on it causes premature aging and rotting! The longer your roof has this growing on it, the sooner you will have to replace it costing you thousands of dollars for a new roof.

Some contractors use light pressure washing to clean a roof, is this safe?

You should never use a pressure washer to clean a roof. Some contractors that don’t know how to clean a roof will tell you it’s ok so that they can make a quick dollar. Your warranty on your roof will void and the bacteria will grow right back.

Why does my roof have black discoloration?

These “black streaks” are a form of cyano bacteria (algae.) This bacteria thrives in humid climates. It also feeds on the limestone filler being used on your shingles causing premature aging, rotting, and granule loss. Each year the black agale will get worse and decrease the life of your shingles. Shingle manufacturers recommend that it be removed and treated to fullfill the life of the shingles.
