Will these streaks damage my roof?

There is debate over the actual harmfulness of this form algae some ‘experts’ say it holds moisture within shingles causing premature aging, rotting, and/or granule loss. At Grime Solutions our opinion is no it will not cause damage, however the lichens and moss that commonly grow along side the algae have a root system and can cause extensive damage if left go.

I’ve never had a problem with unsightly streaks before. Why now?

Fiberglass/asphalt shingles that are used today are made with a limestone filler. These shingles hold moisture and organic “bacteria food” material longer (especially on the North-side) than the paper/asphalt/ceramic shingles of 20+ years ago. Additionally, these particular bacteria enjoy the limestone as a food source.
