Roof Cleaning for Farmington Hills homes

Black streaks on Farmington Hills roofs are a type of algae, Gloeocapsa magma, that feeds on the limestone filler in asphalt shingles and grows fastest where trees keep a slope shaded and damp. With the city's tree cover, north facing slopes on colonials and the long rooflines of ranches both streak early. Branches that hang over the roof also leave moss along the lower edge. A low pressure soft wash kills both without stripping the granules that protect the shingles.

  • North slopes under mature trees streak first.
  • Long, low ranch rooflines show streaks plainly from the street.
  • Moss collects along edges where branches overhang the roof.

Roof Cleaning questions from Farmington Hills

How much does roof cleaning cost in Farmington Hills?
It depends on roof size, pitch and growth. Most Farmington Hills roofs can be measured from satellite.
Are the black streaks on my Farmington Hills roof dirt or damage?
Neither. They are algae living on the shingles. They do not mean the roof is failing, but they make it look older, and a soft wash removes them.
Should I trim trees before having my roof cleaned?
Trimming branches that touch or hang over the roof lets it dry faster, which slows the algae and moss from coming back. It is not required before cleaning.
Can you clean a long, low ranch roof?
Yes for shingled slopes. If part of the roof is a flat membrane over a porch or addition, that section is handled differently, so point it out when you book.
Will cleaning the roof affect my gutters?
The rinse water runs through the gutters, so we check that they drain before we start. Many customers have the gutters cleaned on the same visit.
