Frequently Asked Questions

It is easy to see on most homes while the growth is in the process; there are dark black streaks, particularly on the north-facing roof, though once the algae have fully taken over it is sometimes hard to tell. (It's never too late to remove.) The best place to look to find out if your roof is dirty is below metal roof jacks flashing and skylights. There you should find lighter colored streaks or patches...that are the original color and that is what your roof will look like after we have completed our service!

Yes. Pressure washing will dislodge the granules from the surface of the shingles and can scar the shingles causing more problems than you started with. Shingle manufacturers make it very clear that no pressure should be used to clean roofs. Although leaving the roof apparently clean looking, pressure washing alone does not kill the algae and the problem quickly returns. Tile roofs are also susceptible to damage from pressure, particularly the glaze finish and color pigment. The typical result is that the tile loses its color and is left far more porous. The new porous surface fosters the regrowth of algae, lichen, and moss. Removing the outer surface of roof tile using pressure also allows moisture to enter the tile which accelerates degradation.

As soon as you notice any signs of shading or staining. The gloeocapsa magma bacteria is relatively easy to remove. Moss and lichen require much more time and effort. Even after the treatment, a small amount of dead moss will remain, left to decompose over time. The best time to treat a dirty roof is before signs of moss or lichen.

Yes. Cleaning your roof can save you money in more ways than one...

  • First, the algae and fungus that grow can cause premature roof granule loss, and shorten roof shingle life. So you save money because your roof lasts longer
  • Second, when the algae turn your roof black, it becomes less reflective, and it retains heat; If you use an air conditioner it has to work harder to overcome the increased heat load, costing money in electric bills.
  • Third, the aesthetics of cleaning your roof when it comes to selling your home can not only save you money but can make you money too.
