The Liability of Clogged Valleys and Moss Growth
The function of the roof system is to shed rainwater efficiently and prevent it from entering the home. Wind-blown leaf and twig litter tend to accumulate in roof valleys, slowing the flow of rainwater from two sides of the roof. Colonies of moss swell with moisture and trap dust dislodged by rainwater. Both factors slow the shedding of rainwater over the roof and with heavy buildup can cause unwanted pooling of water on the roof and shingles.

Roof Moss and Lichen




Moss and lichen colonies can be the silent killer for your roof.
Characteristics and effects of lichen and moss:
Lichen is a self-sufficient symbiosis between fungi and algae
Moss is a primitive version of a plant that forms spores
We find both on north-facing roofs (least amount of sun)
Also found where trees and large shrubs shade the roof
Both lichen and moss colonies attach to and degrade shingles

Colonies of moss may look dead in the summer but watch out
when there is a hint of moisture! Click link to right:
Mats of moss trap dust and organic material, creating
a self-perpetuating, moisture trapping danger to roof shingles.


We treat your property as if it were our own. Aggressive techniques and harsh chemicals are avoided in favor of non-abrasive methods and eco-friendly cleaners. Our priority is to minimize stripping asphalt granules from your expensive shingles.
Without abatement, over time, moss filaments with collected particles wedge underneath singles and can even force them upward.
