The growth of fungus and algae spores can create black streaks on asphalt and fiberglass roofs. This can lead to water leaks, the need for roof replacements and may even reduce the value and appeal of your home.
Most often you will find these streaks on the north side of your roof, as this side of your house receives the least amount of sunlight during the day. The moist environment creates a breeding ground for algae and fungus to grow.
To do their job, gutters and downspouts must be clear of leaves and debris. If they aren’t, drain outlets will dam up and rainwater will fill the gutters, overflow, and eventually pull the gutters loose. Water that pools in the eaves troughs will rot the wood behind the gutters and rust surrounding metal. Foundation problems can also occur from plugged gutters. All of these can add up to costly repairs that can be alleviated through proper maintenance. Gutter cleaning is recommended twice a year to minimize structural damage.
The “Tiger Stripes” on your gutters are unsightly. These black streaks are a result of electrostatic bonding of tar & asphalt from roofing material and other debris to metal material. Call us today for a free estimate on “whitening” your gutters, making them look new again!
