House Washes, Roof Washes, & More!

  Tree coverage

 create the ideal shaded environment for moss.

Leaves or loose debris

 hold constant moisture on surfaces, accelerating stains.

Dormers, bump-outs, chimneys, & skylights

 create additional roof shade.

Gutter downspouts

 create stains from dirty water run-off.

Type of material

the more porous the material, the more likely to stain.

Moss and algae thrive in shaded areas with limited to no sunlight, especially areas that can hold moisture for long periods of time. If your roof does not receive direct sunlight due to the environment surrounding your property, it is likely that moss and organic staining will grow.

 Although all factors may not be controllable in some regions (woodsy areas or areas exposed to limited sunlight), it is important to know what is causing stains to spread in order for us to provide the best options for prevention!
